Navigating

The following sections describe navigating in the MD-CLI.

Tree structure

The MD-CLI tree contains the following elements from the Nokia YANG models:

  • container

    This is an element that contains other elements.

Containers

In the following example, tcp-keepalive and gnmi are containers.

tcp-keepalive {
    admin-state disable
    idle-time 600
    interval 15
    retries 4
}
gnmi {
    admin-state enable
    auto-config-save false
}
  • list

    This is a sequence of list entries.

Lists

In the following example, the entire set of interfaces is a list.

        group "group-1" {
            connect-retry 600
            keepalive 33
        }
        group "group-2" {
            description "Text description for group-2"
            local-preference 8
        }
  • list entry

    This is an element similar to a container with multiple instances where each list entry is identified by the values of its keys.

List entries

In the following example, group ‟group-2” is identified in this way.

router "Base" {
    bgp {
        group "group-1" {
            connect-retry 600
            keepalive 33
        }
        group "group-2" {
            description "Text description for group-2"
            local-preference 8
        }
    }
}
  • key

    This is a unique identifier for a list entry.

Keys

In the following example, ‟group-1” and ‟group-2” are unique identifiers.

router "Base" {
    bgp {
        group "group-1" {
            connect-retry 600
            keepalive 33
        }
        group "group-2" {
            description "Text description for group-2"
            local-preference 8
        }
    }
}
  • leaf

    This is an element that does not contain any other elements and has a data type (for example, string or integer). A leaf can also be defined with no data type where the leaf takes no parameter value (that is, an empty leaf).

Leafs

tcp-keepalive {
    admin-state disable
    idle-time 600
    interval 15
    retries 4
}
gnmi {
    admin-state enable
    auto-config-save false
}
  • leaf-list

    This is an element that contains a sequence of values of a particular data type.

Leaf-list

In the following example, ‟policy” is a leaf-list element.

    policy ["policy-a" "policy-b" "policy-c"]
  • leaf-list entry

    This is one of the values of a leaf-list.

Leaf-list entries

In the following example, ‟policy-a”, ‟policy-b”, and ‟policy-c” are leaf-list entries.

    policy ["policy-a" "policy-b" "policy-c"]

The following terms are also used:

  • keyword

    This is an element with a name defined by SR OS. For example, enumerated values, leaf names, and container names.

  • variable parameter

    This is an element with a name defined by the user. For example, descriptions, names, integer or string leaf values.

  • immutable element

    This is an element that can only be configured in the transaction in which the parent element is created. It cannot be modified while the parent element exists.

  • choice element

    This is an element which is part of a set of mutually exclusive elements. Setting a choice element clears all configuration from the other choice elements.

Elements in the tree structure

In the following example, admin-state (leaf name), enable (enumerated value), and connect-retry (leaf name) are keywords, and ‟800” is a variable parameter.

*[ex:/configure router "Base" bgp]
A:admin@node-2# info
    admin-state enable
    connect-retry 800

Managing the router configuration using the MD-CLI involves accessing and configuring the appropriate elements (containers, lists, leafs, and leaf-lists).

The MD-CLI tree shows the commands and parameters (also known as elements) that are available in a hierarchical output.

tree detail command output

In the following, the bold elements are containers (or container lists) which contain leafs (or leaf-lists).

Command prompt

The MD-CLI command prompt displays on two lines. The first line contains the following information:

  • baseline status indicator

    This indicator displays an exclamation mark (!) to indicate an out-of-date baseline when in a configuration mode.

  • uncommitted changes indicator

    This indicator displays an asterisk (*) to indicate uncommitted configuration changes when in a configuration mode.

  • configuration mode reference

    When in a configuration mode, a configuration mode reference is displayed:

    • in round brackets for an explicit configuration workflow

    • prepended to the context, separated by a colon for an implicit configuration workflow

    The configuration mode reference can be one of the following:

    ex
    exclusive mode
    gl
    global mode
    pr
    private mode
    ro
    read-only mode
  • context

    The present working context is displayed in square brackets ([]) when in operational or configuration mode.

For an explicit configuration workflow, the format of the first line is as follows:

<baseline status indicator > <uncommitted changes indicator> (<configuration mode>) [context]

Explicit configuration workflow

(ro)[/]

(ex)[/configure router "Base" bgp]

For an implicit configuration workflow, the format of the first line is as follows:

<baseline status indicator> <uncommitted changes indicator> [<configuration mode>:context]

Implicit configuration workflow

[ro:/configure]

*[ex:/configure]

The second line contains the following information:

  • CPM

    The active CPM slot can be A or B on 7450 ESS and 7750 SR routers, and A,B,C, or D on 7950 XRS routers.

  • user

    The user is the name of the current user for this session.

  • name

    The name is the system name, as configured with the configure system name command. The system name can change dynamically during the session if it is configured to a different name.

The format of the second line is as follows:

CPM:user@name#

Two-line prompt usage

The following examples display the two-line prompt in different modes.

  • prompt in operational mode
    [/]
    A:admin@node-2#
    
  • prompt in the operational root, with exclusive configuration mode
    (ex)[/]
    A:admin@node-2#
    
  • prompt in operational mode show router bgp
    [/show router "Base" bgp]
    A:admin@node-2#
    
  • prompt in exclusive configuration mode configure router bgp
    (ex)[/configure router "Base" bgp]
    A:admin@node-2#
    
  • prompt in exclusive configuration mode configure router bgp with uncommitted changes
    *(ex)[/configure router "Base" bgp]
    A:admin@node-2#
    
  • implicit configuration workflow prompt for a session in private configuration mode, with a present working context of configure router bgp with uncommitted changes in the private candidate datastore, and the baseline datastore out-of-date
    !*[pr:/configure router "Base" bgp]
    A:admin@node-2#
    

Environment commands

The MD-CLI has two environment configurations:

  • the global environment configuration in the configure system management-interface cli md-cli context, which is persistent in the saved configuration file. Changes made to the global environment configuration apply only to new sessions and do not affect current sessions.
  • the per-session environment configuration in the environment context, which is not persistent and applies only to each user's current session. The global environment configuration is copied to the per-session environment configuration when a new session is started.

See the 7450 ESS, 7750 SR, 7950 XRS, and VSR MD-CLI Command Reference Guide for information about the environment commands in the MD-CLI.

Command aliases

The MD-CLI can be customized to provide an enhanced user experience through the use of command aliases.

Aliases can be configured to execute a user-defined command name that performs a specific action. Supported actions include:

  • executing an MD-CLI command
  • executing a Python application

Creating aliases

Aliases can be created and modified in the per-session context or the global configuration configure system management-interface cli md-cli environment context. Aliases (or elements of the aliases) that are deleted in the per-session environment context return to their defaults (usually to the state of the global environment alias defined in the configuration context).

When an alias is configured, the alias acts as a substitute for a command or set of commands that can then be executed. Nokia recommends defining alias names that are meaningful to the operator. Alias names must not use any string that is an MD-CLI root element, such as admin, or that is an MD-CLI global command, such as insert. Aliases are displayed in command completion and ? help, where applicable.

The MD-CLI command history displays what was entered in the CLI. Instead of recording the resultant operation, the history records the alias name and any arguments.

Typical use cases for MD-CLI command aliases include:

  • shortcuts for navigating MD-CLI contexts
  • creating new MD-CLI output commands
  • aliasing existing MD-CLI commands
Note: Expressions (wildcard, range, and regular expressions) are not supported in alias list keys.

Mounting an alias

Aliases are mounted at specific points in the MD-CLI contexts. Aliases may be mounted globally using the mount-point global option. A globally mounted alias may be executed from any MD-CLI context.

Execution of a globally mounted alias

The following example shows the execution of a globally mounted alias that creates the alias up for the back command.


command-alias {
    alias "up" {
        admin-state enable
        cli-command "back"
        mount-point global { }
    }
}

[ex:/configure router "Base" bgp]
A:admin@node-2# up  # Moved back one level by typing “up”


[ex:/configure router "Base"]
A:admin@node-2# uPress Tab  # Integrated into MD-CLI command completion

 up

 update

[ex:/configure router "Base"]
A:admin@node-2# up ?  # Accepts parameters and displays ? help for aliased command

 [[levels] <number>]
 <number> - <1..4294967295>
 Default  - 1

    Number of levels to move up

Alternatively, an alias may be mounted at one or more specific locations, which limits the contexts from which the alias may be executed. The execution of such an alias can be considered equivalent to executing the resultant operation from the present working context of the mount point.

Execution of an alias mounted in the /show and /tools perform contexts
command-alias {
    alias "hello-from-some-places-only" {
        admin-state enable
        python-script "hello"
        mount-point "/show" { }
        mount-point "/tools perform" { }
    }
}

[/]
A:admin@node-2# show hello-from-some-places-only
Hi

[/]
A:admin@node-2# tools perform hello-from-some-places-only
Hi

[/show]
A:admin@node-2# hello-from-some-places-only
Hi

[/tools]
A:admin@node-2# hello-from-some-places-only
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^
MINOR: MGMT_CORE #2201: Unknown element - 'hello-from-some-places-only'

Mount points may contain lists. Where lists are provisioned, the keys must be provided. If lists have default keys, these may be omitted. List keys do not need to be present in the current configuration.

Alias using a nonexistent list key in a mount point

The key vpn3 does not exist as a current VPRN service. When vpn3 is entered on the command line, the resultant configuration shows the string vpn3 enclosed in quotation marks, escaped by the backslash (\) character.

[ex:/configure system management-interface cli md-cli environment command-alias]
A:admin@node-2# info /state service vprn Press Tab

 <service-name>
 "vpn1"
 "vpn2"

[ex:/configure system management-interface cli md-cli environment command-alias alias "list-keys-in-mount-point-example"]
A:admin@node-2# mount-point "/state service vprn vpn3"

*[ex:/configure system management-interface cli md-cli environment command-alias alias "list-keys-in-mount-point-example"]
A:admin@node-2# info
    admin-state enable
    python-script "hello"
    mount-point "/state service vprn \"vpn3\"" { }
Alias automatically available

When the list key is created, the alias automatically becomes available in the context, as shown in the following example.

[/]
A:admin@node-2# state service vprn "vpn3" list-keys-in-mount-point-example
                                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
MINOR: MGMT_CORE #2201: Unknown element - 'list-keys-in-mount-point-example'

[/]
A:admin@node-2# edit-config exclusive
INFO: CLI #2060: Entering exclusive configuration mode
INFO: CLI #2061: Uncommitted changes are discarded on configuration mode exit

(ex)[/]
A:admin@node-2# configure service vprn vpn3

*(ex)[/configure service vprn "vpn3"]
A:admin@node-2# customer "1"

*(ex)[/configure service vprn "vpn3"]
A:admin@node-2# commit

(ex)[/configure service vprn "vpn3"]
A:admin@node-2# state service vprn vpn3 list-keys-in-mount-point-example
Note: Ranges are not supported in cli-command or mount-point commands.

Configuring aliases to execute Python applications

An alias can execute a configured Python application. The alias python-script command can reference a Python application configured in the /configure python python-script context.

See Accounting and authorization of aliases for information about authorizing Python application execution using the alias command.

Configuring aliases to execute MD-CLI commands

An alias may execute an MD-CLI command by using the alias cli-command command. The command is configured using a string that contains the MD-CLI command to execute. The string must be syntactically correct and quotation marks (single or double quotes) must be escaped using the backslash (\) character. If the string contains a list, the list key must be provided, except in the following cases:
  • the list key has a default entry
  • the list key is the last element of the CLI command
Simplified navigation within the MD-CLI
command-alias {
    alias "go-to-alias" {
        admin-state enable
        cli-command "configure system management-interface cli md-cli environment command-alias"
        mount-point global { }
    }
}

[ex:/configure router "Base" bgp]
A:admin@node-2# go-to-alias

[ex:/configure system management-interface cli md-cli environment command-alias]
A:admin@node-2#

Key provided as a parameter

A list key can be omitted if the last element of the CLI command string is a list. This allows the key to be provided as a parameter when executing the alias, as shown in the following example.

command-alias {
    alias "vprn-state" {
        admin-state enable
        cli-command "info candidate /state service vprn"
        mount-point "/show" { }
    }
}

[/]
A:admin@node-2# show vprn-state
                     ^^^^^^^^^^

    creation-origin manual
    vrtr-id 2
    oper-router-id 255.0.0.0
    oper-route-distinguisher-type auto

...snip...
Extra parameters executed

Aliases can also accept arguments, allowing extra parameters to be executed, as shown in the following example.

[/]
A:admin@node-2# show vprn-state vpn1 interface "test1" ipv4 icmp
    statistics {
        icmp-in-msgs 0
        icmp-in-errors 0
        icmp-in-dest-unreachables 0
        icmp-in-redirects 0
        icmp-in-echos 0
        icmp-in-echo-replies 0
        icmp-in-time-exceeds 0
        icmp-in-src-quenches 0
        icmp-in-timestamps 0
        icmp-in-timestamp-replies 0

        icmp-out-errors 0
        icmp-out-dest-unreachables 0
        icmp-out-redirects 0
        icmp-out-echos 0
        icmp-out-echo-replies 0
        icmp-out-time-exceeds 0
        icmp-out-src-quenches 0
        icmp-out-timestamps 0
        icmp-out-timestamp-replies 0
        icmp-out-address-masks 0
        icmp-out-address-mask-replies 0
        icmp-out-parm-problems 0
        icmp-out-discards 0
    }
Include output modifiers in definitions

Aliases that execute CLI commands may also include output modifiers in the definitions. In the following example, the alias bgp-top-line outputs the line from show router bgp summary that uses the output match modifier to select a specific string:

command-alias {
    alias "bgp-top-line" {
        admin-state enable
        cli-command "show router bgp summary | match \"AS:\""
        mount-point global { }
    }
}

[/]
A:admin@node-2# bgp-top-line
 BGP Router ID:255.0.0.0        AS:65535       Local AS:65535

Accounting and authorization of aliases

Aliases have specific accounting and authorization rules, as shown in the following configuration example.

command-alias {
    alias "my-python-alias" {
        admin-state enable
        python-script "hello"
        mount-point global { }
    }
    alias "my-cli-alias" {
        admin-state enable
        cli-command "info running /state service vprn"
        mount-point global { }
    }
    alias "my-cli-python-alias" {
        admin-state enable
        cli-command "pyexec cf3:\hello.py"
        mount-point global { }
    }
}

The command entered by the operator on the MD-CLI command line is sent to the accounting system, including all arguments supplied to the alias.

For example, if the operator enters my-cli-alias vpn1, the string my-cli-alias vpn1 is sent to the accounting system. If the operator enters my-python-alias, the string my-python-alias is sent to the accounting system.

The string sent to the authorization system depends on whether cli-command or python-script is configured in the alias context.

When an alias uses a CLI command, the resulting MD-CLI command is sent to the authorization system. For example, if the operator enters my-cli-alias vpn1, the string sent to the authorization system is info running /state service vprn vpn1. If the operator enters my-cli-python-alias, the string sent to the authorization system is pyexec cf3:\hello.py

If the alias is configured with the python-script option, the string sent to the authorization server is the referenced Python application name prefaced by the string python-script. This allows Python applications initiated with the pyexec command to be authorized independently of those initiated from within MD-CLI command aliases. Administrators can predefine approved Python applications that may be executed by users who otherwise have no access to run the pyexec command.

For example, if the operator enters my-python-alias, the string sent to the authorization server is python-script \”hello\”.

Customizing per-session environment settings

The environment can be customized for all sessions in the configuration under the configure system management-interface cli md-cli environment context, or per session using the environment command. When a new MD-CLI session is started, the per-session environment configuration is copied from the global environment configuration. Changes made to the global environment configuration after the session begins apply only to new sessions and do not affect current sessions. Changes made to the environment parameters for a session apply only for that session.

The per-session environment is accessed by entering environment at the operational root or with /environment from any other mode or context. Changes made in the per-session environment are immediate.

The info command displays the difference between the per-session environment and the configured global environment parameters. Therefore, for a new MD-CLI session, the info command has no output, as the per-session environment is the same as the global environment. The info detail command displays the current values in the global environment for all parameters.

Customizing the session prompt

Customizing the uncommitted changes indicator

As the default setting of the environment configuration, the uncommitted changes indicator is displayed as part of the command prompt. This setting can be modified per session or it can be changed for all MD-CLI sessions by changing the environment configuration.

The uncommitted-changes-indicator command under the environment prompt context suppresses or displays the change indicator for an MD-CLI session. Environment changes are applied immediately and are lost when the session disconnects.

*[/environment prompt]
A:admin@node-2# uncommitted-changes-indicator false

[/environment prompt]
A:admin@node-2#

[/environment prompt]
A:admin@node-2# uncommitted-changes-indicator true

*[/environment prompt]
A:admin@node-2#

Customizing the line preceding the command prompt

By default, a blank line precedes the command prompt. This setting can be modified for each MD-CLI session.

The newline command under the environment prompt context suppresses or displays a new line before the prompt.


[/]
A:admin@node-2# environment prompt

[/environment prompt]
A:admin@node-2# newline false
[/environment prompt]
A:admin@node-2# newline true

[/environment prompt]
A:admin@node-2#

Customizing the context information in the command prompt

By default, the context is displayed in the command prompt. This setting can be modified for each MD-CLI session.

The context command under the environment prompt context suppresses or displays the current context.

[/environment prompt]
A:admin@node-2# context false

[]
A:admin@node-2# context true

[/environment prompt]
A:admin@node-2#

Customizing the date and time output

By default, the timestamp is not displayed before the command prompt. This setting can be modified for each MD-CLI session.

The timestamp command under the environment prompt context suppresses or displays the timestamp.

Suppress or display the timestamp
[/environment prompt]
A:admin@node-2# timestamp true

Tue, 16 Feb 2021 16:37:26 UTC
[/environment prompt]
A:admin@node-2# timestamp false

[/environment prompt]
A:admin@node-2#

The environment time-display command configures the time zone display to UTC or local time (as configured in configure system time).

Configure the time zone display
[/environment]
A:admin@node-2# time-display ?

 time-display <keyword>
 <keyword> - (local|utc)
 Default   - local


    Time zone to display time

The environment time-format command specifies the format for the time display.

Specify the format for the time display
[/environment]

A:admin@node-2# software-last-boot-time
    software-last-boot-time 2020-09-01T23:27:17.0+00:00

Customizing the progress indicator

The progress indicator appears on the line immediately following the command and disappears when the MD-CLI command completes or when output is available to display. The indicator is a display of dynamically changing dots.

Progress indicator

[ex:/configure]
A:admin@node-2# compare
...                    # progress indicator displays here as dots 

The delay interval can be configured using the delay command or the indicator can be disabled with the admin-state disable command under the environment progress-indicator context.

Customizing the progress indicator for logged sessions

[/environment progress-indicator]
A:admin@node-2# ?

 admin-state          - Administrative state of the progress indicator
 delay                - Delay before progress indicator is displayed
 type                 - Progress indicator output style

Customizing the pagination setting

The environment more command enables pagination when configured to true and disables pagination when configured to false.

Using the environment more command

Customizing the console settings

The default size for a console terminal is 80 characters wide by 24 lines long. The environment console command can be used to change these settings.

[/environment]
A:admin@node-2# console ?

 console

 length               - Number of lines displayed on the screen
 width                - Number of columns displayed on the screen

Customizing the message level security settings

The INFO: CLI messages are displayed by default. The environment message-security-level command suppresses the INFO messages by changing the setting to warning.

[/environment message-severity-level]
A:admin@node-2# cli ?

 cli <keyword>
 <keyword> - (warning|info)
 Default   - info

    Message severity threshold for CLI messages

Following are examples of INFO: CLI messages that are suppressed when the setting is changed to warning.

INFO: CLI #2051: Switching to the classic CLI engine
INFO: CLI #2052: Switching to the MD-CLI engine
INFO: CLI #2054: Entering global configuration mode
INFO: CLI #2056: Exiting global configuration mode 
INFO: CLI #2055: Uncommitted changes are present in the candidate configuration
INFO: CLI #2057: Uncommitted changes are kept in the candidate configuration

Customizing configuration output display

Default values are always displayed in the info detail command output and not in the info command output. Use the environment info-output always-display admin-state command to display the values of the admin-state element in the info command output (without using the detail option), even if these values are set to the default. Enabling the admin-state command allows the info command output to always show the admin-state value without showing all the configured, default, and unconfigured values that are displayed using the info detail command. For more information, see Using the info command.

In the following configuration output, the admin-state for port 1/1/2 with a default configuration is not displayed using the info command. The admin-state is displayed after the environment info-output always-display admin-state command is configured to true.

[ex:/configure port 1/1/2]
A:admin@node-2# info

[ex:/configure port 1/1/2]
A:admin@node-2# /environment info-output always-display admin-state

[ex:/configure port 1/1/2]
A:admin@node-2# info
    admin-state disable

Preventing changes to environment settings

The environment datastore is subject to AAA command authorization. A user can be prevented from modifying the global environment settings or the per-session environment settings, or both.

In the following configuration output, entry 113 blocks user ‟tstuser” from modifying the global environment settings. In addition, entry 114 prevents the user from changing the per-session environment settings.

 Default     - TiMOS CLI

    Script policy owner

Immutable elements

An immutable element can only be configured in the transaction in which the parent element is created. It cannot be modified while the parent element exists. Any modification to an immutable element in model-driven interfaces causes SR OS to automatically delete the parent element and recreate it with the new value for the immutable element.

Immutable elements defined in online help

 'level' is: mandatory, immutable

    Maintenance Domain Level (MD Level)

    Warning: Modifying this element recreates
    'configure eth-cfm domain "example_domain"' automatically for the new value
    to take effect.

Mutually exclusive choice elements

Elements that are part of a choice are listed in a separate section in the online help. Mandatory choices are listed first. Each choice contains a set of mutually exclusive elements or groups of elements. The first element of a group is indicated with a colon (:).

The following example shows a set of two mutually exclusive choice elements for an ingress queue rate. If configuring one of the choice elements, either the cir and fir values can be configured or the police value.

*[ex:/configure qos sap-ingress "ing-1" queue 1 rate]
A:admin@node-2# ?

 pir                   - Administrative PIR

 Choice: rate-cir-fir-or-police

 fir                   - Administrative FIR
 police               :- Drop the traffic feeding into queue above the PIR rate

Optional indicators in the online help

The following help display is an example of optional indicators.

Optional indicators

The square brackets ([]) around slot-number indicate that the slot-number keyword is optional when entering the command.

[ex:/configure]
A:admin@node-2# card ?

 [slot-number] <number>
 <number> - <1..20>

    Slot number within the chassis

The card context can be entered as one of the following.

[ex:/configure]
A:admin@node-2# card slot-number 5

or

[ex:/configure]
A:admin@node-2# card 5

Angle brackets (<>) indicate a variable name and the vertical bar (|) indicates a choice.

sub-group command

For the sub-group command, a number in the range of 1 to 8 can be entered, or one of the keywords auto-iom or auto-mda.

*[ex:/configure lag "lag-8" port 1/1/1]
A:admin@node-2# sub-group ?

 sub-group (<number> | <keyword>)
 <number>  - <1..8>
 <keyword> - (auto-iom|auto-mda)
 Default   - 1

 'sub-group' is: immutable

    Subgroup of the port in the LAG

    Warning: Modifying this element recreates
    'configure lag "lag-8" port 1/1/1' automatically for the new value to take
    effect.

  • back

    The back command can be used to go back one or more levels. If no parameter value is specified for the number of levels to go back, the default is one level. Using back at the top of the current command tree moves the context to the operational root level. If the number of levels specified is greater than the current depth, the context moves to the operational root. A closing brace (}) can also be used to go back one level.

    *[ex:/configure card 1 mda 2 network]
    A:admin@node-2# back
    
    *[ex:/configure card 1 mda 2]
    A:admin@node-2# back 2
    
    *[ex:/configure]
    A:admin@node-2# back 5
    
    *[ex:/]
    A:admin@node-2#
    
  • top

    The top command moves the context to the top of the current command tree without exiting the mode. Use the top command instead of issuing the back command multiple times to move the context to the top of the command tree.

    *(ex)[/]
    A:admin@node-2# configure
    
    *(ex)[/configure]
    A:admin@node-2# card 1
    
    *(ex)[/configure card 1]

    A:admin@node-2# top
    
    *(ex)[/configure]
    A:admin@node-2#
    
  • exit

    The exit command moves the context to the previous context in the current command tree. If the previous context was up one level, the exit command functions similarly to the back command. Using exit all moves the context to the operational root. A slash (/) or Ctrl-Z can also be used instead of exit all. Using exit at the operational root has no effect. To log out of the system, the logout command must be used.

Available commands with mutually exclusive commands

When a command that is part of a choice of commands is entered at the MD-CLI command prompt, the other mutually exclusive commands are no longer available to be entered on the same prompt line. Other commands that are not associated with the particular choice commands are still available.

In the following example, if either the cir or fir command is entered, the police command is not available. The pir command is available regardless of which choice command is entered.

*[ex:/configure qos sap-ingress "ing-1" queue 1 rate]
A:admin@node-2# ?

 pir                   - Administrative PIR

 Choice: rate-cir-fir-or-police
 cir                  :- Administrative CIR
 fir                   - Administrative FIR
 police               :- Drop the traffic feeding into queue above the PIR rate

*[ex:/configure qos sap-ingress "ing-1" queue 1 rate]
A:admin@node-2# cir max Press Tab

 fir     pir

 delete

Similarly, if the police command is entered, the cir and fir commands are unavailable on the same command prompt line.

*[ex:/configure qos sap-ingress "ing-1" queue 1 rate]
A:admin@node-2# police ?

 police - This element has no values

    Drop the traffic feeding into queue above the PIR rate

 pir                   - Administrative PIR

*[ex:/configure qos sap-ingress "ing-1" queue 1 rate]
A:admin@node-2# police Press Tab

 pir

 delete

Using command completion

The MD-CLI supports both command abbreviation and command completion. When typing a command, Tab, Spacebar, or Enter invokes auto-completion. If the text entered is enough to match a specific command, auto-completion completes the command. If the text entered is not sufficient to identify a specific command, pressing Tab or Spacebar displays options in alphabetical order matching the text entered.

The environment command-completion command controls what keystrokes can trigger command completion. Each keystroke is independently controlled with its own Boolean value.

(ex)[/environment command-completion]
A:admin@node-2# info detail
    enter true
    space true
    tab true
Note: If Spacebar completion has multiple matches and also matches an keyword, the space is considered a separator and auto-completion is not triggered.
  • configure por+Spacebar displays auto-completion results

  • configure port+Spacebar inserts a space and suppresses auto-completion results

  • configure por+Tab displays auto-completion results

  • configure port+Tab displays auto-completion results

Variable parameter completion

Variable parameter completion works only with the Tab key. All configured variables from the candidate and running configuration datastores are displayed. Line wrapping may occur for variables with long names. Parameters are displayed in alphabetical or numerical order. The variable parameter name is always displayed as the first line.

In the following example, "interface-name" is the variable parameter name and "int-1" and "system" are configured names.

*[ex:/configure router "Base"]
A:admin@node-2# interface Press Tab 

 <interface-name>
 "int-1"
 "system"

*[ex:/configure router "Base"]
A:admin@node-2# interface

Completion for lists with a default keyword

Some list elements have a default keyword defined, such as the router command, where the default keyword is "Base". When the command completion parameters (Enter, Spacebar, and Tab) are at their default settings (true), and the initial input matches an element in the list and a unique command keyword, the matching keyword is completed instead of the variable.

For example, the router command has a default keyword defined as "Base". If router "bf" is created using the command configure router "bf" (with quotation marks), and there is an existing bfd command context, the variable completion is as follows.

Display for router+Spacebar+Tab
*[ex:/configure]
A:admin@node-2# router Press Tab

 <router-name>
 "Base"
 "bf"
 "management"

 aggregates             allow-icmp-redirect    allow-icmp6-redirect
 apply-groups           apply-groups-exclude   autonomous-system
 bfd                    bgp                    bier
 
---snip---
Display for router bf+Tab
*[ex:/configure]
A:admin@node-2# router bfPress Tab

 "bf"

 bfd
Entering router bf+Enter

Entering router bf+Enter completes to router bfd and enters the router "Base" bfd context:

*[ex:/configure]
A:admin@node-2# router bfd Press Enter

*[ex:/configure router "Base" bfd]
A:admin@node-2#
Entering router bf+Spacebar

Similarly, router bf+Spacebar completes to router bfd and enters the router "Base" bfd context when Enter is pressed:

*[ex:/configure]
A:admin@node-2# router bfd Press Spacebar+Enter

*[ex:/configure router "Base" bfd]
A:admin@node-2#
Using quotation marks to specify a variable

To enter the context for router "bf", use quotation marks to specify the variable:

[ex:/configure]
A:admin@node-2# router "bf"

*[ex:/configure router "bf"]
A:admin@node-2#
Command completion for enter set to false

If the command completion for enter is set to false, router bf+ Enter allows the match to router "bf". Similarly, when the command completion for space is false, router bf+Spacebar also matches to router "bf" instead of the bfd context

*(ex)[/environment command-completion]
A:admin@node-2# info detail
    enter true
    space true
    tab true

*(ex)[/environment command-completion]
A:admin@node-2# enter false

*(ex)[/environment command-completion]
A:admin@node-2# space false

*(ex)[/environment command-completion]
A:admin@node-2#

*(ex)[/]
A:admin@node-2# configure

*(ex)[/configure]
A:admin@node-2# router bf Press Enter 

*(ex)[/configure router "bf"]
A:admin@node-2# back

*(ex)[/configure]
A:admin@node-2# router bf Press Spacebar+Enter

*(ex)[/configure router "bf"]
A:admin@node-2#

Completion for keyword-based leaf-lists

For keyword-based leaf-lists, command completion displays all possible values, not only those that are configured. When deleting values in a leaf-list, only the values that are currently configured are displayed.

In the following example, when defining the forwarding traffic classes, all keyword values are listed. When deleting the forwarding traffic classes, only the configured classes are displayed.

*[ex:/configure policy-options policy-statement "ss" entry 3 from]
A:admin@node-2# family ?

 family <value>
 family [<value>...] - 1..20 system-ordered values separated by spaces enclosed
                        by brackets

              vpn-ipv6|sr-policy-ipv4|sr-policy-ipv6|flow-vpn-ipv4|flow-
              vpn-ipv6)

    Address family as the match condition
   
*[ex:/configure policy-options policy-statement "ss" entry 3 from]
A:admin@node-2# family [ipv4 mcast-ipv4 mcast-vpn-ipv4 label-ipv4]

*[ex:/configure policy-options policy-statement "ss" entry 3 from]

A:admin@node-2# delete family Press Tab

 <family>
 ipv4
 mcast-ipv4
 mcast-vpn-ipv4
 label-ipv4
 *

Completion for Boolean elements

The explicit use of the keyword true for a Boolean element is optional. If neither true or false is entered, the keyword true is assumed.

(ex)[/environment]
A:admin@node-2# more ?

 more <boolean>
 <boolean> - ([true]|false)
 Default   - true

    Activate the pager when output is longer than a screen

When Tab is used for command completion with Boolean elements, the values of false and true are displayed, along with the names of possible elements that can follow.

In the following example of the environment more command, the commands command-completion, console, message-severity-level, and so on, can be defined following the more command.

(ex)[/environment]
A:admin@node-2# more Press Tab

 <more>
 false
 true

 command-completion      console                 message-severity-level
 progress-indicator      prompt                  time-display
 time-format

 delete

Modifying the idle timeout value for CLI sessions

A single idle timeout applies to all CLI engines in a CLI session (classic and MD-CLI). The idle timeout can be modified to a value between 1 and 1440 minutes.

The following points apply:

  • The idle timeout only affects new CLI sessions. Existing and current sessions retain the previous idle timeout.

  • The idle timeout can be disabled by setting the value to none.

  • The "Idle time" column in the show users display is reset after an action in either CLI engine.

A warning message is displayed when a session reaches one-half the value of the idle timeout, and another message is displayed when the idle timeout expires and the user is logged out.

Idle timeout interaction with the classic CLI

The idle timeout configured in the classic CLI affects all new sessions as well as the current session. However, the current session is only affected if the classic CLI engine is active when the idle timeout expires. Configuration changes via the MD-CLI or any other interface only affect new sessions that begin after the change.

Using the pager

The MD-CLI pager paginates command output one screenful at a time. It supports movement and searching in forward and backward directions.

The status line at the bottom of the screen displays the following information.

--(more)--(p%)--(lines b-e/t)--

where

  • p - indicates the position percentage in the output
  • b - indicates the beginning line of the output on the screen
  • e - indicates the ending line of the output on the screen
  • t - indicates the total lines in the output
--(more)--(5%)--(lines 1-29/527)—

If the command output is still being generated, a question mark ("?") is displayed after the total lines and a warning indicates that the search is incomplete. These indicators are removed when the command output completes.

--(more)--(0%)--(lines 1-29/49833?)--(warning: search will be incomplete)--

The pager supports a high number of output lines. If the command output exceeds the pager memory, an asterisk (*) is displayed after the total lines and a warning indicates that the search is incomplete.

--(more)--(0%)--(lines 3578-3607/93151747*)--(warning: search will be incomplete)--

The following table describes the general and movement commands available for use.

Note: (n) indicates that a command may be preceded by a number n.
Table 3. General and movement commands
Action Command

Move to the beginning of the output g, p, open angle bracket (<), Ctrl-A, Home
Move to the end of the output G, closed angle bracket ( >), End
Jump to line (n) g, G

The output can be searched by entering a search command followed by a string or regular expression at the bottom of the screen. The first match in the output is highlighted and underlined on the screen, and repeating the search displays the next match. Re-entering the search command displays the previous search so that it can be edited.

Searching with a string

The following string search matches any string containing "mda".

/mda

Searching with a regular expression

The following regular expression search matches the neighbor with the IP address that ends with 42 (neighbor "10.81.192.42").

/nei.*42

See Using regular expressions for more information about using regular expressions. The regular expression is highlighted until it is valid. Highlighting occurs when delimiters such as () and [] are unmatched, or when an asterisk (*) or question mark (?) is entered without a preceding expression.

The following table describes the search commands available for use.

Table 4. Search commands
Action Command
Forward search forward slash (/)
Backward search question mark (?)
Repeat previous forward search n
Repeat previous backward search N
Clear search highlighting c, Ctrl-L, Esc+U

The following usage guidelines apply to the pager:

  • the minimum supported terminal size is 80 characters wide by 24 lines long
  • resizing the terminal when the pager is active is not supported

Using output modifiers

Output modifiers provide support for post-processing of CLI output. Output modifiers are specified using a vertical bar (|) character. The following points apply when using output modifiers:

  • Output modifiers can be appended to any CLI command in any command context.

  • Output modifiers work across soft line breaks (visual lines) that are wrapped because of the terminal width; for example, using match or count. They do not work across hard line breaks (logical lines).

  • Modifiers can be combined in any order. No hard limit exists for the number of combinations. Output is processed linearly and there is little impact on the system performance except to the operator session that entered the modifier combination.

Using | match options

The following options are supported for use with the pipe (|) match command:

  • ignore-case

    This specifies to ignore case in pattern match.

  • invert-match

    This specifies to invert the pattern match selection.

  • max-count

    This specifies the maximum number of displayed matches.

  • post-lines

    This specifies the number of lines to display following the matched line.

  • pre-lines

    This specifies the number of lines to display preceding the matched line.

The default pattern matching is a string match. If the required pattern to match includes a space, the pattern must be delimited by quotation marks ("). Regular expressions are delimited by apostrophes ('). See Using regular expressions for more information about using regular expressions.

The following example matches on the pattern autonomous-system in the tree detail under the configure router "Base" context, and starts the display with ten lines preceding the pattern match.

[ex:/configure router "Base"]
A:admin@node-2# tree detail | match autonomous-system pre-lines 10
|   |   +-- local-preference <number>
|   |   +-- policy <reference>
|   |   +-- summary-only <boolean>
|   |   +-- tunnel-group <number>
|   +-- apply-groups <reference>
|   +-- apply-groups-exclude <reference>
+-- allow-icmp-redirect <boolean>
+-- allow-icmp6-redirect <boolean>
+-- apply-groups <reference>
+-- apply-groups-exclude <reference>
+-- autonomous-system <number>

---snip---

Using the | count option

The | count option displays the line count of the output.

Note: Error messages are not processed by output modifiers. They are always displayed and are not affected by the count or match modifiers.
[ex:/configure router "Base"]
A:admin@node-2# tree flat detail | match seamless-bfd
bfd seamless-bfd
bfd seamless-bfd peer <unicast-ipv4-address | global-unicast-ipv6-address>
bfd seamless-bfd peer <unicast-ipv4-address | global-unicast-ipv6-address> apply-groups <reference>
bfd seamless-bfd peer <unicast-ipv4-address | global-unicast-ipv6-address> apply-groups-exclude <reference>
bfd seamless-bfd peer <unicast-ipv4-address | global-unicast-ipv6-address> discriminator <number>

[ex:/configure router "Base"]
A:admin@node-2# tree flat detail | match seamless-bfd | count
Count: 5 lines

Using the | no-more option

The | no-more option displays the output with pagination disabled for the command. This option is similar to the environment more false setting that applies to all commands, where the entire output text is printed without page interruptions.

Using the | reverse-dns option

The | reverse-dns option performs a reverse DNS lookup on any IPv4 or IPv6 address in the input to the output modifier. The result of the lookup is inserted as the next line in the output on each line where an IP address is identified. If no match is found, no additional output is printed.

Using the file redirect option

The > option can be used to redirect output to a local or remote file. The > redirect must be specified at the end of a command and cannot be combined with other redirects.

[ex:/configure router "Base"]

Using regular expressions

Regular expressions (REs) used by the MD-CLI engine are delimited by apostrophes ('); for example, '.*'. REs cannot be delimited by quotation marks ("); for example, ".*" because this indicates a string match.

MD-CLI REs are based on a subset of The Open Group Base Specifications Issue 7 and IEEE Std 1003.1-2008, 2016 Edition REs, as defined in chapter 9. MD-CLI REs only support Extended Regular Expression (ERE) notation as defined in section 9.4. Basic Regular Expression (BRE) notation as defined in section 9.3 is not supported.

In ERE notation, a backslash (\) before a special character is treated as a literal character. Backslashes are not supported before ( ) or { }, as they are in BREs to indicate a bracket expression or marked expression.

Table 5. Special characters in extended regular expressions
Special character Description

.

Matches any single character

*

Matches the preceding expression zero or more times

?

Matches the preceding expression zero or one time

+

Matches the preceding expression one or more times

[ ]

Matches a single character within the brackets

[^]

Matches a single character not within the brackets

^

Matches the starting position

$

Matches the ending position

( )

Defines a marked subexpression

{m,n}

Matches the preceding expression at least m and not more than n times

{m}

Matches the preceding expression exactly m times

{m, }

Matches the preceding expression at least m times

{ ,n}

Matches the preceding expression not more than n times

|

Matches either expression preceding or following the |

\

Escapes and treats the following character as a match criterion

-

Separates the start and end of a range

The following examples show the use of a bracket expression as a matching list expression.

Using no match expressions

The first output does not use any match expressions and therefore shows the entire output.

Using matching list expression

In this matching list expression, a match is any single character in the bracket expression, which in this case is 1, 3, or 5.

[/]
A:admin@node-2# show port | match '1/1/[135]'
1/1/1         Down  No   Ghost   8704 8704    - netw null xcme

1/1/12        Down  No   Ghost   8704 8704    - netw null xcme

Using non-matching list expression

In this non-matching list expression, a match is any single character not in the bracket expression, that is, not 1, 2, or 4.

[/]
A:admin@node-2# show port | match '1/1/[^124]'
1/1/3         Up    No   Ghost   1514 1514    - accs null xcme

1/1/9         Down  No   Ghost   8704 8704    - netw null xcme

Using the range operator

The range operator (-) can be used in a matching or non-matching list expression.

[/]
A:admin@node-2# show port | match '1/1/[3-7]'
1/1/3         Up    No   Ghost   1514 1514    - accs null xcme

1/1/12        Down  No   Ghost   8704 8704    - netw null xcme

Using the alternation operator

The alternation operator (|) can be used with or without a bracket expression to match against two or more alternative expressions.

[/]
A:admin@node-2# show port | match '1/1/[2-5|7-9]'
1/1/2         Up    No   Ghost   1514 1514    - accs null xcme
1/1/3         Up    No   Ghost   1514 1514    - accs null xcme
1/1/4         Up    No   Ghost   1514 1514    - accs null xcme
1/1/5         Up    No   Ghost   1514 1514    - accs null xcme
1/1/7         Down  No   Ghost   8704 8704    - netw null xcme
1/1/8         Down  No   Ghost   8704 8704    - netw null xcme
1/1/9         Down  No   Ghost   8704 8704    - netw null xcme

Using no bracket expression

Without a bracket expression, an exact match is attempted against two or more alternative expressions.

*[ex:/configure card 1]
A:admin@node-2# info | match '10g|100g'
        mda-type imm4-10gb-xp-xfp
        mda-type cx2-100g-cfp

MD-CLI REs match on the output format of an element, as is shown in the configuration. For example, if the value of an element is shown in hexadecimal in info output, a decimal RE does not match the value.

Using anchoring special characters

MD-CLI REs are not implicitly anchored. This complete configuration is used to show how the ^ or $ anchoring special characters can be used to match in the following examples.

*[ex:/configure router "Base" bgp]
A:admin@node-2# info
    group "external" {
    }
    group "internal" {
    }
    neighbor "192.168.10.1" {
        group "external"
        keepalive 30
        peer-as 100
    }
    neighbor "192.168.10.2" {
        group "external"
        peer-as 100
        family {
            ipv4 true
        }
    }

Using the anchor character preceded by four spaces

This example uses the ^ anchor character to match on "group" preceded by four spaces at the beginning of the line.

*[ex:/configure router "Base" bgp]
A:admin@node-2# info | match '^    group' pre-lines 1
    group "external" {
    }
    group "internal" {

Using the anchor character preceded by eight spaces

This example uses the ^ anchor character to match on "group" preceded by eight spaces at the beginning of the line.

*[ex:/configure router "Base" bgp]
A:admin@node-2# info | match '^        group' pre-lines 1
    neighbor "192.168.10.1" {
        group "external"
    neighbor ""192.168.10.2" {
        group "external"

Using the compare command

In the following configuration example using the compare command, the | match option filters out those commands to be deleted (configuration statements beginning with minus (-)) and those to be added (configuration statements beginning with plus (+)).

*[ex:/configure log accounting-policy 5]
A:admin@node-2# /compare
+   admin-state enable
-   collection-interval 105
+   collection-interval 75
-   include-system-info true
+   include-system-info false

*[ex:/configure log accounting-policy 5]
A:admin@node-2# /compare | match '^-'
-   collection-interval 105
-   include-system-info true

Using the backslash

The backslash (\) is used to match the literal "+" character that denotes additions to the configuration seen in the compare command.

*[ex:/configure log accounting-policy 5]
A:admin@node-2# /compare | match '^\+'
+   admin-state enable
+   collection-interval 75
+   include-system-info false

A character class expression is expressed as a character class name enclosed within bracket colon ("[:" and ":]") delimiters.

Character class expressions must be enclosed within brackets. The expression ‛[[:digit:]]’ is treated as an RE containing the character class ‟digit”, while ‛[:digit:]’ is treated as an RE matching ‟:”, ‟d”, ‟i”, ‟g”, or ‟t”.

Collating symbols and equivalence classes are not supported in MD-CLI REs.

Configuring an empty container or a list where the only children are keys does not navigate into the context. These elements are displayed with aggregated braces with a space ({ }) on the same line. It is possible to enter the element name with an opening brace; however, no options are available in this context.

Configuring the list element sdp-include

For example, configuring the list element sdp-include with a key of ‟ref_group_name” does not change the existing context.

*[ex:/configure service pw-template "tt"]
A:admin@node-2# sdp-include ref_group_name

*[ex:/configure service pw-template "tt"]
A:admin@node-2# info
    sdp-include "ref_group_name" { }

*[ex:/configure service pw-template "tt"]
A:admin@node-2#

Exiting contexts

The back and top commands are used to navigate contexts, but it is also possible to use closing braces (}) to navigate.

The behavior of an explicit closing brace depends on the contents of the current command line. If the command line contains an explicit opening brace, the closing brace exits to the parent context of the opening brace.

In the following example with an opening brace on the command line, the closing brace exits VPRN 1, and then enters the context of VPRN 2.

(ex)[/]
A:admin@node-2# configure service vprn 1 { interface "intf1" description "vprn-if" } vprn 2

*(ex)[/configure service vprn "2"]
A:admin@node-2#

In the following example without an opening brace on the command line, the first closing brace exits interface "int1", and the second closing brace exits VPRN 1 and enters the VPRN 2 context.

*[ex:/configure service]
A:admin@node-2# vprn 1 interface "int1" description "vprn-if" } } vprn 2

*[ex:/configure service vprn "2"]
A:admin@node-2#

Executing commands from a file

The exec command executes commands from a file as if the user typed or pasted the input into the MD-CLI.

The exec command:

  • errors if it detects an interactive input

  • terminates in the CLI engine in which it completes execution as follows:

    • If there are no commands that switch CLI engines, the CLI engine is always the one in which exec started.

    • If there are commands that switch CLI engines, exec ends in the last CLI engine that was entered.

    • //exec returns to the engine in which it was started.

  • may error when used with file redirect (>) or output modifiers (|)
  • terminates execution and displays an error message if an error occurs, leaving the session in the same context as when the error occurred

The system executes the file as follows:

  • disables pagination while the command is running

  • disables command completion while the command is running

  • suppresses the commands in the file from the command history

Note: The exec command should not be used to enter configuration statements. Use the load command instead.

Using commands that switch engines in an executable file

When using commands that switch between CLI engines within an executable file, the following commands are recommended:

  • Use /!classic-cli to switch explicitly to the classic CLI engine and /!md-cli to switch explicitly to the MD-CLI engine, instead of // to toggle between engines.

  • Use exit all to get to a known starting point: the operational root of the classic CLI or the MD-CLI engine.

  • Include edit-config if the script needs to change the candidate configuration in the MD-CLI engine. Use quit-config after changes are committed in the script.

    Note:
    • An executable with edit-config may fail if other users have locked the configuration.

    • Issuing the quit-config command with changes in the candidate configuration while the session is in exclusive configuration mode fails the executable because of the ‟discard changes” prompt.

Displaying information

Using the info command

The info command shows configuration or state information from the present context. The command can only be executed in a configuration mode for a configuration region or for the state branch. By default, all configured parameters in the candidate configuration datastore are displayed for a configuration region. For a state region, all elements that have a value are displayed.

Table 7. Displaying configuration from configuration groups and third-party models with info options
Usage Info option Datastore Nokia configuration Configuration groups Third-party model configuration
Display third-party configuration converted to Nokia configuration converted Running Nokia and converted third-party configuration with origin comments groups and unexpanded apply-groups statements
Display the configuration with configuration groups inheritance inheritance Any groups and expanded apply-groups statements with origin comments Native format
Display third-party configuration converted to Nokia configuration with configuration groups inheritance converted inheritance Running Nokia and converted third-party configuration with origin comments groups and expanded apply-groups statements with origin comments
Display the expanded configuration applied by the router intended Intended Expanded configuration without groups or apply-groups statements or origin comments Native format
Note: The converted and model options are only available when configure system management-interface yang-modules openconfig-modules is set to true.
Note: The output of info flat and info full-context display braces relative to the context from which the command is executed so that the session remains in the context if the output is pasted.

Execute the command from the configuration root to stay at the root context without navigating.

Note: As indicated in the choice statement, the flat, json, and xml options are mutually exclusive options. Other unsupported combinations include:
  • [from] candidate and converted

  • [from] intended and converted

  • [from] intended and detail

  • [from] intended and inheritance

  • full-context and flat

  • model and detail

  • model and inheritance

  • units and json

  • units and xml

The order of the configuration output is as follows:

  • Keys are displayed on the same line as the command element.

  • apply-groups is displayed, if applicable.

  • apply-groups-exclude is displayed, if applicable.

  • admin-state is displayed, if applicable.

  • description is displayed, if applicable.

  • Other top-level elements are displayed in alphabetical order.

Displaying configured information

The following displays configured information for configure router bgp.

*[ex:/configure router "Base" bgp]
A:admin@node-2# info
    connect-retry 90
    local-preference 250
    add-paths {
        ipv4 {
            receive true
        }
    }

The following output displays the same information in JSON IETF format.

[ex:/configure router "Base" bgp]
A:admin@node-2# info json
{
    "nokia-conf:connect-retry": 90,
    "nokia-conf:local-preference": 250,
    "nokia-conf:add-paths": {
        "ipv4": {
            "receive": true
        }
    }
}

The following output displays the same information in XML format:

[ex:/configure router "Base" bgp]
A:admin@node-2# info xml
<connect-retry xmlns="urn:nokia.com:sros:ns:yang:sr:conf" xmlns:nokia-attr="urn:nokia.com:sros:ns:yang:sr:attributes">90</connect-retry>
<local-preference xmlns="urn:nokia.com:sros:ns:yang:sr:conf" xmlns:nokia-attr="urn:nokia.com:sros:ns:yang:sr:attributes">250</local-preference>
<add-paths xmlns="urn:nokia.com:sros:ns:yang:sr:conf" xmlns:nokia-attr="urn:nokia.com:sros:ns:yang:sr:attributes">
    <ipv4>
        <receive>true</receive>
    </ipv4>
</add-paths>

The configuration output can display all elements that are configured, even if an element is set to the system default state or value. The detail option displays all data for the context, including default configurations. The double hash (##) indicates an unconfigured element or a dynamic default.

Displaying all configured elements

*[ex:/configure router "Base" bgp]
A:admin@node-2# info detail
 ## apply-groups
    admin-state enable
 ## description
    connect-retry 90
    keepalive 30
    damping false
    local-preference 250
    loop-detect ignore-loop
    loop-detect-threshold 0
    selective-label-ipv4-install false
    min-route-advertisement 30
    aggregator-id-zero false
    preference 170
    block-prefix-sid false
 ## multihop
 ## med-out
 ## authentication-key
    client-reflect true
    vpn-apply-export false
    vpn-apply-import false
    asn-4-byte true

When using the info command with both the detail and xml options, the double hash (##) elements (indicating unconfigured elements or dynamic defaults) are enclosed within XML comments.

Using the detail and xml options

*[ex:/configure router "Base" bgp] 
A:admin@node-2# info detail xml
<!-- ## apply-groups -->
<!-- ## apply-groups-exclude -->
<admin-state xmlns="urn:nokia.com:sros:ns:yang:sr:conf" xmlns:nokia-attr="urn:nokia.com:sros:ns:yang:sr:attributes">enable</admin-state>
<!-- ## description -->
<connect-retry xmlns="urn:nokia.com:sros:ns:yang:sr:conf" xmlns:nokia-attr="urn:nokia.com:sros:ns:yang:sr:attributes">90</connect-retry>
<keepalive xmlns="urn:nokia.com:sros:ns:yang:sr:conf" xmlns:nokia-attr="urn:nokia.com:sros:ns:yang:sr:attributes">30</keepalive>
<damping xmlns="urn:nokia.com:sros:ns:yang:sr:conf" xmlns:nokia-attr="urn:nokia.com:sros:ns:yang:sr:attributes">false</damping>
<local-preference xmlns="urn:nokia.com:sros:ns:yang:sr:conf" xmlns:nokia-attr="urn:nokia.com:sros:ns:yang:sr:attributes">250</local-preference>

...

When using the info command with both detail and json options, the output does not include unconfigured elements. Unconfigured elements in the MD-CLI are denoted with ## and there is no standard method of displaying comments within the JSON format.

Using the detail and json options

[ex:/configure router "Base" bgp]
A:admin@node-2# info detail json
{
    "nokia-conf:admin-state": "enable",
    "nokia-conf:connect-retry": 90,
    "nokia-conf:keepalive": 30,
    "nokia-conf:damping": false,
    "nokia-conf:local-preference": 250,

    "nokia-conf:inter-as-vpn": false,
    "nokia-conf:purge-timer": 10,
    "nokia-conf:route-table-install": true,

...

The flat option displays the context of every element in the present working context on a single line. Braces ensure that the context stays in the present working context for copy and paste purposes.

Using the flat option

*[ex:/configure router "Base" bgp]
A:admin@node-2# info flat
connect-retry 90
    local-preference 250
    add-paths ipv4 receive true

The full-context option displays the full context of every element from the present working context on a single line.

Using the full-context option

*[ex:/configure router "Base" bgp]
A:admin@cses-V93# info full-context
    /configure router "Base" bgp connect-retry 90
    /configure router "Base" bgp local-preference 250
    /configure router "Base" bgp add-paths ipv4 receive true

When the full-context option is used in conjunction with the json or xml option, the output is modified to display the configuration back to the YANG model-aware root of the configuration tree.

Using the full-context option with the json or xml option

[ex:/configure router "Base" bgp]
A:admin@node-2# info full-context json
{
    "nokia-conf:configure": {
        "router": [
            {
                "router-name": "Base",
                "bgp": {
                    "connect-retry": 90,
                    "local-preference": 250,
                    "add-paths": {
                        "ipv4": {
                            "receive": true
                        }
                    }
                }
            }
        ]
    }
}
[ex:/configure router "Base" bgp]
A:admin@node-2# info full-context xml
<configure xmlns="urn:nokia.com:sros:ns:yang:sr:conf" xmlns:nokia-attr="urn:nokia.com:sros:ns:yang:sr:attributes">
    <router>
        <router-name>Base</router-name>
        <bgp>
            <connect-retry>90</connect-retry>
            <local-preference>250</local-preference>
            <add-paths>
                <ipv4>
                    <receive>true</receive>
                </ipv4>
            </add-paths>
        </bgp>
    </router>
</configure>

The depth option displays configuration from the present working context limited to the specified depth. Use this option to suppress output that is lower in the hierarchy. For example, if the present working context is configure, the depths of the commands are:

  • configure router = 1
  • configure router description = 2
  • configure router interface description = 3

Using the depth option

[ex:/configure router "Base"]
A:admin@node-2# info depth 1
    autonomous-system 65816
    router-id 172.16.255.0
    }
    interface "system" {
    }
    bgp {
    }
    isis 0 {
    }

Displaying lists

The info command requires the user to enter a list key name. Users can enter the wildcard asterisk (*) character, a range, or a regular expression instead of a list key name to display a subset of keys with one command. For more information, see Using expressions in commands.

Displaying lists with a list key name
[ex:/configure]
A:admin@node-2# info sfm 1
    sfm-type sfm-s

[ex:/configure]
A:admin@node-2# info sfm 2
    mda-type sfm-s
Displaying lists with the wildcard * character
[ex:/configure]

        sfm-type sfm-s
    }
    sfm 2 {
        sfm-type sfm-s
    }
    sfm 3 {
        sfm-type sfm-s
    }
    sfm 4 {
        sfm-type sfm-s
    }
Displaying lists with a range
[ex:/configure]
A:admin@node-2# info sfm [3..4]
    sfm 3 {
        sfm-type sfm-s
    }
    sfm 4 {
        sfm-type sfm-s
    }

[ex:/configure]
A:admin@node-2# info sfm [1,3]
    sfm 1 {
        sfm-type sfm-s
    }
    sfm 3 {
        sfm-type sfm-s
    }

[ex:/configure]
A:admin@node-2# info port 1/1/[1..3]
    port 1/1/1 {
        admin-state enable
    }
    port 1/1/2 {
        admin-state enable
    }
    port 1/1/3 {
        admin-state enable
   }
Displaying lists with a regular expression
[ex:/configure router "Base"] 
A:admin@node-23# info interface 'sys'
 interface "system" {
     ipv4 {
         primary {
             address 172.16.255.0
             prefix-length 32
         }
      }
  }

The info command always displays all keys of the list on the same line. The first key of a list is unnamed in the MD-CLI, however, there are exceptions where the key is named and must be entered. (See the online help for the correct command syntax , or the 7450 ESS, 7750 SR, 7950 XRS, and VSR MD-CLI Command Reference Guide). All other keys are named.

For example, the collector list has two keys, ip-address and port. The name of the first key, ip-address, does not appear in the info display. The name of the second key and any subsequent keys are always displayed.

*[ex:/configure cflowd]
A:admin@node-2# info
    collector 10.10.20.30 port 7 {
    }
    collector 10.10.30.40 port 8 {
    }

Operational command availability

The clear, monitor, show, and tools commands in the MD-CLI display the same information and provide the same functionality as they do in the classic CLI. No additional outputs or enhancements are included in the MD-CLI. See the 7450 ESS, 7750 SR, 7950 XRS, and VSR Clear, Monitor, Show, and Tools CLI Command Reference Guide for more information about the SR OS CLI commands that are used to manage the SR OS in either CLI engine.

Note: Follow the classic CLI context when using the show command. For example, route policy information is displayed using the show router policy command in both the MD-CLI and classic CLI engines, even though this information is configured in the configure policy-options context in the MD-CLI and in the configure router policy-options context in the classic CLI.

The following classic CLI show commands are not available in the MD-CLI and have equivalent commands:

  • show alias

    Use the MD-CLI info detail environment command-alias command.

  • show bof

    Use the MD-CLI admin show configuration bof command or the info command in the bof configuration region.

  • show debug

    Use the MD-CLI admin show configuration debug command or the info command in the debug configuration region.

  • show system candidate

    Use the MD-CLI info command in a configuration mode.

  • show system rollback

    Use the MD-CLI show system management-interface commit-history command.

Displaying configuration with admin commands

The admin show commands display the same configuration as the info command but are not subject to command authorization and do not require configuration mode access.

See the 7450 ESS, 7750 SR, 7950 XRS, and VSR MD-CLI Command Reference Guide for information about the admin commands in the MD-CLI.

The following examples show the admin show configuration output of the running configuration in the default configuration region (configure). Other configuration regions can also be specified, including bof, debug, and li.

Using paths in commands

As described in Navigating hierarchy levels, the pwc command displays the present working context. Navigating around the MD-CLI hierarchy changes the present working context.

The MD-CLI path format, also known as cli-path, is displayed in the MD-CLI user prompt.

MD-CLI path format

[ex:/configure card 1 mda 1]
A:admin@node-2# pwc
Present Working Context:
  configure
  card 1
  mda 1

For the following commands, an absolute or relative MD-CLI path can be specified to provide path qualified attributes:

The CLI path is accepted as an unnamed last parameter of the command. The information is displayed for the specified path.

Information displayed for a specified CLI path


[ex:/configure]
A:admin@node-2# info candidate detail units /configure system
 ## apply-groups
 ## apply-groups-exclude
 ## contact
    name "node-2"
 ## location
    icmp-vse false
    selective-fib false
 ## coordinates
 ## clli-code
    ospf-dynamic-hostnames false

---snip---

A configuration lock from either implicit or explicit configuration mode is required to display paths for a configuration region.

The state branch does not have a lock and can always be specified.

state branch

[ex:/configure]
A:admin@node-2# info detail /state system
    oper-name "node-2"
    base-mac-address aa:bb:cc:00:00:00
    platform "7750 SR-12"
    chassis-topology standalone
    crypto-module-version "SRCM 3.1"
 ## fabric-speed
    temperature-status ok
    fp-generation-fp2 false
    fp-generation-fp3 false
    fp-generation-fp4 false
    fp-generation-fp5 false
    system-profile none
    active-cpm-slot "A"

info command with a state path

The following example shows the use of the info command with a state path from operational mode.

[/]
A:admin@node-2# info /state system
    oper-name "node-2"
    base-mac-address aa:bb:cc:00:00:00
    platform "7750 SR-12"
    chassis-topology standalone
    crypto-module-version "SRCM 3.1"
    temperature-status ok
    fp-generation-fp2 false
    fp-generation-fp3 false
    fp-generation-fp4 false
    fp-generation-fp5 false
    system-profile none
    active-cpm-slot "A"

Establishing a configuration lock

In the next example, to use the info command in a state context to a configuration region, a configuration lock must be established.

[/state system]
A:admin@node-2# info /configure system
                      ^^^^^^^^^
MINOR: MGMT_CORE #2203: Invalid element - currently not allowed

[/state system]
A:admin@node-2# edit-config read-only
INFO: CLI #2066: Entering read-only configuration mode

(ro)[/state system]
A:admin@node-2# info /configure system
    name "node-2"
    management-interface {
        configuration-mode mixed
        snmp {
            admin-state disable
        }

---snip---

Supported commands with a CLI path parameter

(ex)[/state router "Base" bgp]
A:admin@node-2# info /state router bgp statistics routes-per-family ipv4
    remote-routes 45
    remote-active-routes 6
    backup-routes 0

*(ex)[/state router "Base" bgp]
A:admin@node-2# compare /configure system
-   name "test1"
+   name "test"

(ex)[/configure router "Base" bgp]
A:admin@node-2# discard /configure system

(ex)[/configure router "Base"]
A:admin@node-2# tree bgp group "mesh" add-paths ipv4
+-- receive
+-- send

[/]
A:admin@node-2# admin show configuration /configure router isis interface "system"
    passive true

(ex)[/configure policy-options]
A:admin@node-2# copy policy-statement "mytest" to /configure policy-options policy-statement "my_new_policy"

(ex)[/configure router "Base" bgp]
A:admin@node-2# rename /configure policy-options policy-statement "mytest" to "another_new_policy" 

Absolute path

An absolute CLI path is specified using the slash (/) as the MD-CLI tree structure from the root.

CLI path references a section of the MD-CLI tree under the indicated context

/configure card 1 mda 1

CLI path references a specific leaf in the tree

/state system oper-name

Relative path

A relative CLI path specifies the MD-CLI tree structure from the present working context.

In the following example, the two info commands display the same information. The first command usage is an absolute path reference and the next usage is a relative path from the present working context (pwc).

[ex:/configure router "Base" bgp]
A:admin@node-2# pwc
Present Working Context:
  configure
  router "Base"
  bgp

[ex:/configure router "Base" bgp]
A:admin@node-2# info /configure router "Base" bgp group "grp1"

[ex:/configure router "Base" bgp]
A:admin@node-2# info group "grp1"

Using expressions in commands

Several commands accept a path. For these commands, use expressions to specify multiple list keys in one command instead of entering multiple commands. For example, expressions can be used with the info command to display configuration or state information, and in configuration statements to enter parameter values. The following tables lists the expressions that can be used with each command.

Table 8. Using expressions in commands
Command Wildcard Range Regular expression

admin show configuration

annotate

compare

copy

delete

discard

info

insert

rename

replace

The wildcard asterisk (*) character can be entered to specify all list keys, for example info port * or configure port * admin-state enable.

To specify a range of numbers that is expanded sequentially into list keys, enter a numerical range enclosed in brackets ([]). Ranges entered with numbers separated by two periods (..) are incremented by 1 when expanded, for example port 1/1/[1..5]. A comma (,) can be used to enter multiple numbers or ranges.

The following table lists some example ranges and how they are expanded. Numbers are processed in the order they are entered; for example, a range of [3,6] expands to 3 and 6, and a range of [6,3] expands to 6 and 3. Ranges can be at any place in a string, for example vprn[1..3].

Table 9. Example range and expansion
Range Expansion

[1..5]

1 2 3 4 5

[3,6]

3 6

[6,3]

6 3

[1..5,9]

1 2 3 4 5 9

[1..3,6,8..10]

1 2 3 6 8 9 10

A range can have a backreference to a previous range in the same command line. The reference has the form [$n]

where n is a single digit from 0 to 9 and 0 is the first match.

For example:

  • configure service vprn [1..5] router-id 10.20.[$0].1 expands to:
    • configure service vprn 1 router-id 10.201.1.1
    • configure service vprn 2 router-id 10.201.2.1
    • configure service vprn 3 router-id 10.201.3.1
    • configure service vprn 4 router-id 10.201.4.1
    • configure service vprn 5 router-id 10.201.5.1
  • configure router interface int[1..4] ipv6 address 2001:db8:[$0]:[1..10]::1 prefix-length 64 expands to:
    • four interfaces named int1, int2, int3, int4, each with 10 IPv6 addresses

To specify a set of strings that is expanded sequentially into list keys, enter an alphabetical sequence enclosed in brackets ([]). Strings must be separated by a comma (,), and enclosed in quotes (“) if they contain spaces. For example, configure router interface [one,“second int",three] specifies interfaces named “one”, “second int”, and “three”.

To specify a matching condition for list keys, enter a regular expression enclosed in apostrophes (‘). See Using regular expressions for more information.
