Event and accounting logs
This chapter provides information about configuring event and accounting logs on the 7210 SAS.
Logging overview
The two primary types of logging supported on the 7210 SAS are event logging and accounting logs.
Event logging controls the generation, dissemination and recording of system events for monitoring status and troubleshooting faults within the system. The 7210 SAS groups events into four major categories or event sources:
security events
These are events that pertain to attempts to breach system security.
change events
These are events that pertain to the configuration and operation of the node.
main events
These are events that pertain to applications that are not assigned to other event categories/sources.
debug events
These are events that pertain to trace or other debugging information.
The following are events within the 7210 SAS and have the following characteristics:
a time stamp in UTC or local time
the generating application
a unique event ID within the application
the VRF-ID
a subject identifying the affected object
a short text description
Event control assigns the severity for each application event and whether the event should be generated or suppressed. The severity numbers and severity names supported on the 7210 SAS conform to ITU standards M.3100 X.733 and X.21 and are listed in the following table.
Severity number |
Severity name |
|---|---|
1 |
cleared |
2 |
indeterminate (info) |
3 |
critical |
4 |
major |
5 |
minor |
6 |
warning |
Events that are suppressed by event control do not generate event log entries. Event control maintains a count of the number of events generated (logged) and dropped (suppressed) for each application event. The severity of an application event can be configured in event control.
An event log in the 7210 SAS associates the event sources with logging destinations. Examples of logging destinations include, the console session, a specific Telnet or SSH session, memory logs, file destinations, SNMP trap groups and syslog destinations. A log filter policy can be associated with the event log to control which events are logged in the event log based on combinations of application, severity, event ID range, VRF ID, and the subject of the event.
The 7210 SAS accounting logs collect comprehensive accounting statistics to support a variety of billing models. The routers collect accounting data on services and network ports on a per-service class basis. In addition to gathering information critical for service billing, accounting records can be analyzed to provide insight about customer service trends for potential service revenue opportunities. Accounting statistics on network ports can be used to track link utilization and network traffic pattern trends. This information is valuable for traffic engineering and capacity planning within the network core.
Accounting statistics are collected according to the parameters defined within the context of an accounting policy. Accounting policies are applied to access objects (such as access ports and SAPs) or network objects (such as SDPs, network ports, network IP interface). Accounting statistics are collected by counters for individual services defined on the customer’s SAP or by the counters within forwarding class (FC) queues defined on the network ports.
The type of record defined within the accounting policy determines where a policy is applied, what statistics are collected and time interval at which to collect statistics.
The ‟location” field of the file-id allows the user configure the device and store it in any directory. The default value is cf1:, but it can also be uf1: (for devices supporting USB).
Log destinations
Both event logs and accounting logs use a common mechanism for referencing a log destination.
Only a single log destination can be associated with an event log or with an accounting log. An event log can be associated with multiple event sources, but it can only have a single log destination.
A file destination is the only type of log destination that can be configured for an accounting log.
Console
Sending events to a console destination means the message is sent to the system console. The console device can be used as an event log destination.
Session
A session destination is a temporary log destination that directs entries to the active Telnet or SSH session for the duration of the session. When the session is terminated, for example, when the user logs out, the event log is removed. Event logs configured with a session destination are not stored in the configuration file. Event logs can direct log entries to the session destination.
Memory logs
A memory log is a circular buffer. When the log is full, the oldest entry in the log is replaced with the new entry. When a memory log is created, the specific number of entries it can hold can be specified, otherwise it assumes a default size. An event log can send entries to a memory log destination.
Log files
Log files can be used by both event logs and accounting logs and are stored on the compact flash devices (specifically cf1:) in the file system.
A log file is identified with a single log file ID, but a log file is generally composed of a number individual files in the file system. A log file is configured with a rollover parameter, expressed in minutes, which represents the length of time an individual log file should be written to before a new file is created for the relevant log file ID. The rollover time is checked only when an update to the log is performed. Therefore, complying to this rule is subject to the incoming rate of the data being logged. For example, if the rate is very low, the actual rollover time may be longer than the configured value.
The retention time for a log file specifies the amount of time the file should be retained on the system based on the creation date and time of the file.
When a log file is created, only the compact flash device for the log file is specified. Log files are created in specific subdirectories with standardized names depending on the type of information stored in the log file.
Event log files are always created in the \log directory on the specified compact flash device. The naming convention for event log files is:
log eeff-timestamp
where:
ee is the event log ID
ff is the log file destination ID
timestamp is the timestamp when the file is created in the form of yyyymmdd-hhmmss where:
yyyy is the four-digit year (for example, 2007)
mm is the two digit number representing the month (for example, 12 for December)
dd is the two digit number representing the day of the month (for example, 03 for the 3rd of the month)
hh is the two digit hour in a 24-hour clock (for example, 04 for 4 a.m.)
mm is the two digit minute (for example, 30 for 30 minutes past the hour)
ss is the two digit second (for example, 14 for 14 seconds)
Accounting log files are created in the \act-collect directory on a compact flash device (cf1). The naming convention for accounting log files is nearly the same as for log files except the prefix act is used instead of the prefix log. The naming convention for accounting logs is:
act aaff-timestamp.xml.gz
where:
aa is the accounting policy ID
ff is the log file destination ID
timestamp is the timestamp when the file is created in the form of yyyymmdd-hhmmss where:
yyyy is the four-digit year (for example, 2022)
mm is the two digit number representing the month (for example, 12 for December)
dd is the two digit number representing the day of the month (for example, 03 for the 3rd of the month)
hh is the two digit hour in a 24-hour clock (for example, 04 for 4 a.m.)
mm is the two digit minute (for example, 30 for 30 minutes past the hour)
ss is the two digit second (for example, 14 for 14 seconds)
Accounting logs are .xml files created in a compressed format and have a .gz extension.
The \act-collect directory is where active accounting logs are written. When an accounting log is rolled over, the active file is closed and archived in the \act directory before a new active accounting log file created in \act-collect.
SNMP trap group
An event log can be configured to send events to SNMP trap receivers by specifying an SNMP trap group destination.
An SNMP trap group can have multiple trap targets. Each trap target can have different operational parameters.
A trap destination has the following properties:
the IP address of the trap receiver
the UDP port used to send the SNMP trap
SNMP version (v1, v2c, or v3) used to format the SNMP notification
SNMP community name for SNMPv1 and SNMPv2c receivers
security name and level for SNMPv3 trap receivers
For SNMP traps that are sent in-band, the source IP address of the trap is the system IP address of the 7210 SAS.
Each trap target destination of a trap group receives the identical sequence of events as defined by the log ID and the associated sources and log filter applied.
Syslog
An event log can be configured to send events to one syslog destination. Syslog destinations have the following properties:
syslog server IP address
UDP port used to send the syslog message
Syslog Facility Code (0 - 23) (default 23 - local 7)
Syslog Severity Threshold (0 - 7)
Events that exceed the configured level are sent
Because syslog uses eight severity levels whereas the 7210 SAS uses six internal severity levels, the severity levels are mapped to syslog severities. The following table lists the severity level mappings to syslog severities.

Event logs
Event logs are the means of recording system generated events for later analysis. Events are messages generated by the system by applications or processes within the 7210 SAS.
The following figure shows a function block diagram of event logging.
Event sources
In Event logging block diagram, the event sources are the main categories of events that feed the log manager:
security
The security event source is all events that affect attempts to breach system security such as failed login attempts, attempts to access MIB tables to which the user is not granted access or attempts to enter a branch of the CLI to which access has not been granted. Security events are generated by the SECURITY application and the authenticationFailure event in the SNMP application.
change
The change activity event source is all events that directly affect the configuration or operation of the node. Change events are generated by the USER application. The Change event stream also includes the tmnxConfigModify(#2006), tmnxConfigCreate (#2007), tmnxConfigDelete (#2008) and tmnxStateChange (#2009) change events from the SYSTEM application.
debug
The debug event source is the debugging configuration that has been enabled on the system. Debug events are generated by the DEBUG application.
main
The main event source receives events from all other applications within the 7210 SAS.
Examples of applications within 7210 SAS include IP, MPLS, OSPF, CLI, and services.
The following shows an example of the show log applications command output that displays all applications.

Event control
Event control preprocesses the events generated by applications before the event is passed into the main event stream. Event control assigns a severity to application events and can either forward the event to the main event source or suppress the event. Suppressed events are counted in event control, but these events do not generate log entries because they never reach the log manager.
Simple event throttling is another method of event control and is configured similarly to the generation and suppression options. See Simple logger event throttling.
Events are assigned a default severity level in the system, but the application event severities can be changed by the user.
Application events contain an event number and description that describe why the event is generated. The event number is unique within an application, but the number can be duplicated in other applications.
The following example, generated by querying event control for application generated events, displays a partial list of event numbers and names.

Log manager and event logs
Events that are forwarded by event control are sent to the log manager. The log manager manages the event logs in the system and the relationships between the log sources, event logs and log destinations, and log filter policies.
An event log has the following properties:
a unique log ID
the log ID is a short, numeric identifier for the event log (a maximum of ten logs can be configured at a time)
one or more log sources
the source stream or streams to be sent to log destinations can be specified. The source must be identified before the destination can be specified. The events can be from the main event stream, events in the security event stream, or events in the user activity stream
one event log destination
a log can only have a single destination (the destination for the log ID destination can be one of console, session, syslog, snmp-trap-group, memory, or a file on the local file system)
an optional event filter policy
an event filter policy defines whether to forward or drop an event or trap-based on match criteria
Event filter policies
The log manager uses event filter policies to allow fine control over which events are forwarded or dropped based on various criteria. Like other policies with the 7210 SAS, filter policies have a default action. The default actions are either:
Forward
Drop
Filter policies also include a number of filter policy entries that are identified with an entry ID and define specific match criteria and a forward or drop action for the match criteria.
Each entry contains a combination of matching criteria that define the application, event number, router, severity, and subject conditions. The entry’s action determines how the packets should be treated if they have met the match criteria.
Entries are evaluated in order from the lowest to the highest entry ID. The first matching event is subject to the forward or drop action for that entry.
Valid operators are listed in the following table.
Operator |
Description |
|---|---|
eq |
equal to |
neq |
not equal to |
lt |
less than |
lte |
less than or equal to |
gt |
greater than |
gte |
greater than or equal to |
A match criteria entry can include combinations of:
equal to or not equal to a specific system application
equal to, not equal to, less than, less than or equal to, greater than or greater than or equal to an event number within the application
equal to, not equal to, less than, less than or equal to, greater than or greater than or equal to a severity level
equal to or not equal to a router name string or regular expression match
equal to or not equal to an event subject string or regular expression match
Event log entries
Log entries that are forwarded to a destination are formatted in a way appropriate for the specific destination whether it be recorded to a file or sent as an SNMP trap, but log event entries have common elements or properties. All application generated events have the following properties:
a time stamp in UTC or local time
the generating application
a unique event ID within the application
a router name identifying the VRF-ID that generated the event
a subject identifying the affected object
a short text description
The general format for an event in an event log with either a memory, console or file destination is as follows.
nnnn YYYY/MM/DD HH:MM:SS.SS <severity>:<application> # <event_id> <router-
name> <subject> description
The following is an event log example:
475 2006/11/27 00:19:40.38 WARNING: SNMP #2007 Base 1/1/1
"interface 1/1/1 came up"
The specific elements that compose the general format are described in the following table.

nnnn |
The log entry sequence number. |
YYYY/MM/DD |
The UTC date stamp for the log entry. YYYY — year MM — month DD — date |
HH:MM:SS.SS |

<severity> |
The severity level name of the event. CLEARED — a cleared event (severity number 1) INFO — an indeterminate/informational severity event (severity level 2) CRITICAL — a critical severity event (severity level 3) MAJOR — a major severity event (severity level 4) MINOR — a minor severity event (severity level 5) WARNING — a warning severity event (severity 6) |
<application> |
The application generating the log message. |
<event_id> |

Simple logger event throttling
Simple event throttling provides a mechanism to protect event receivers from being overloaded when a scenario causes many events to be generated in a very short period of time. A throttling rate, # events/# seconds, can be configured. Specific event types can be configured to be throttled. After the throttling event limit is exceeded in a throttling interval, any further events of that type cause the dropped events counter to be incremented. Dropped events counts are displayed by the show>log>event-control context. Events are dropped before being sent to one of the logger event collector tasks. There is no record of the details of the dropped events and therefore no way to retrieve event history data lost by this throttling method.
A specific event type can be generated by multiple managed objects within the system. At the point this throttling method is applied the logger application has no information about the managed object that generated the event and cannot distinguish between events generated by object ‟A” from events generated by object ‟B”. If the events have the same event-id, they are throttled regardless of the managed object that generated them. It also does not know which events may eventually be logged to destination log-id <n> from events that will be logged to destination log-id <m>.
Throttle rate applies commonly to all event types. It is not configurable for a specific event-type. A timer task checks for events dropped by throttling when the throttle interval expires. If any events have been dropped, a TIMETRA-SYSTEM-MIB::tmnxTrapDropped notification is sent.
Default system log
Log 99 is a preconfigured memory-based log that logs events from the main event source (not security, debug, and so on). Log 99 exists by default.

Accounting logs
Before an accounting policy can be created, a target log file must be created to collect the accounting records. The files are stored in system memory on compact flash (cf1:) in a compressed (tar) XML format and can be retrieved using FTP or SCP.
A file ID can only be assigned to either one event log ID or one accounting log.
Accounting records
An accounting policy must define a record name and collection interval. Only one record name can be configured per accounting policy. Also, a record name can only be used in one accounting policy.
When creating accounting policies, one service accounting policy and one network accounting policy can be defined as default. If statistics collection is enabled on a SAP, access-uplink, or network port and no accounting policy is applied, then the respective default policy is used. If no default policy is defined, then no statistics are collected unless a specifically defined accounting policy is applied.
The record name, sub-record types, and default collection period for service and network accounting policies are listed in Accounting record names and collection periods for 7210 SAS-D, Accounting record names and collection periods for 7210 SAS-Dxp, Accounting record names and collection periods for 7210 SAS-K 2F1C2T , Accounting record names and collection periods for 7210 SAS-K 2F6C4T, and Accounting record names and collection periods for 7210 SAS-K 3SFP+ 8C.

Accounting record details
Each accounting record name is composed of one or more sub-records, which are in turn composed of multiple fields.
See Appendix: accounting record name details for 7210 SAS platforms for more information about accounting records and statistics for the 7210 SAS platforms.

The following information describes configuration guidelines:
On the 7210 SAS-D and 7210 SAS-Dxp, the ingress SAP counter counts both octets and packets simultaneously.
On the 7210 SAS-D, the egress SAP counter is disabled by default.
Ensure that egress SAP counters are enabled on 7210 SAS-D devices before associating accounting records of type service-egress-octets, service-egress-packets, combined-service-egress and complete-service-ingress-egress.
Before modifying the counter mode, disable account log generation. Execute the no collect-stats command. Changing the mode of the counter results in loss of previously collected counts and resets the counter.
Egress SAP statistics are not available on any of the SAPs of a port on which a dot1q SAP and dot1q default SAP configuration are present at the same time.
On the 7210 SAS-D and 7210 SAS-Dxp for VLL and VPLS services, the counter-mode of counters associated with SAP ingress meters/policers can be changed by executing the following command:
For 7210 SAS-D and 7210 SAS-Dxp devices — config>service>epipe/vpls>sap>statistics>ingress>counter-mode {in-out-profile-count | forward-drop-count}
For more information about the counter-mode command, See the 7210 SAS-D, Dxp, K 2F1C2T, K 2F6C4T, K 3SFP+ 8C Services Guide.
The statistics collected for the following accounting records vary based on the counter-mode selected:
Service-ingress-octets
Service-ingress-packets
Combined-service-ingress
Complete-service-ingress-egress
Reporting and time-based accounting
Node support for volume and time-based accounting concept provides an extra level of intelligence at the network element level to provide service models such as ‟prepaid access” in a scalable manner. This means that the network element gathers and stores per-subscriber accounting information and compare it with predefined quotas. After a quota is exceeded, the predefined action (such as redirection to a web portal or disconnect) is applied.
Configuration notes
This following information describes logging configuration restrictions:
A file or filter cannot be deleted if it has been applied to a log.
File IDs, syslog IDs, or SNMP trap groups must be configured before they can be applied to a log ID.
A file ID can only be assigned to either one log ID or one accounting policy.
Accounting policies must be configured in the config>log context before they can be applied to a service SAP or service interface, or applied to a network port.
The snmp-trap-id must be the same as the log-id.
Configuring logging with CLI
This section provides information to configure logging using the command line interface.
Log configuration overview
Configure logging parameters to save information in a log file or direct the messages to other devices. Logging does the following:
provides you with logging information for monitoring and troubleshooting
allows you to select the types of logging information to be recorded
allows you to assign a severity to the log messages
allows you to select the source and target of logging information
Log types
Logs can be configured in the following contexts:
Log file
Log files can contain log event message streams or accounting/billing information. Log file IDs are used to direct events, alarms/traps and debug information to their respective targets.
SNMP trap groups
SNMP trap groups contain an IP address and community names which identify targets to send traps following specified events.
Syslog
Information can be sent to a syslog host that is capable of receiving selected syslog messages from a network element.
Event control
Configures a particular event or all events associated with an application to be generated or suppressed.
Event filters
An event filter defines whether to forward or drop an event or trap based on match criteria.
Accounting policies
An accounting policy defines the accounting records that will be created. Accounting policies can be applied to one or more service access points (SAPs), access-uplink (network) ports, and access ports.
Event logs
An event log defines the types of events to be delivered to its associated destination.
Event throttling rate
Defines the rate of throttling events.
Basic event log configuration
The most basic log configuration must have the following:
log ID or accounting policy ID
a log source
a log destination

The following sections describe basic system tasks that must be performed.
Configuring an event log
A event log file contains information used to direct events, alarms, traps, and debug information to their respective destinations. One or more event sources can be specified. File IDs, SNMP trap groups, or syslog IDs must be configured before they can be applied to an event log ID.
Use the following CLI syntax to configure a log file:
config>log
log-id log-id
description description-string

----------------------------------------------
ALA-12>config>log>log-id#
Configuring a file ID
To create a log file, a file ID is defined, the target CF or USB drive is specified, and the rollover retention interval period for the log file is defined. The rollover interval is defined in minutes and determines how long a file is used before it is closed and a new log file is created. The retention interval determines how long the file is stored on the storage device before it is deleted.
Use the following CLI syntax to configure a log file:
config>log
file-id log-file-id
description description-string
location cflash-id
rollover minutes [retention hours]log file configuration
A:ALA-12>config>log# info
------------------------------------------
file-id 1
description "This is a log file."
location cf1:
rollover 600 retention 24
exit
----------------------------------------------
A:ALA-12>config>log#Configuring an accounting policy
Before an accounting policy can be created a target log file must be created to collect the accounting records. The files are stored in system memory of compact flash (cf1:) in a compressed (tar) XML format and can be retrieved using FTP or SCP. See Configuring an event log and Configuring a file ID.
Accounting policies must be configured in the config>log context before they can be applied to a service SAP or service interface, or applied to a network port.
The default accounting policy statement cannot be applied to LDP nor RSVP statistics collection records.
An accounting policy must define a record type and collection interval. Only one record type can be configured per accounting policy.
policy can be defined as default. If statistics collection is enabled on an accounting object, and no accounting policy is applied, then the respective default accounting policy is used. If no default policy is defined, then no statistics are collected unless a specifically-defined accounting policy is applied.
Use the following CLI syntax to configure an accounting policy:
config>log>
accounting-policy acct-policy-id interval minutes
description description-string

A:ALA-12>config>log#
Configuring event control
Use the following CLI syntax to configure event control. Note that the throttle parameter used in the event-control command syntax enables throttling for a specific event type. The config>log>throttle-rate command configures the number of events and interval length to be applied to all event types that have throttling enabled by this event-control command.
config>log
event-control application-id [event-name|event-number] generate [severity-level] [throttle]
event-control application-id [event-name|event-number] suppress

*A:Dut-A>config>log# Configuration guidelines for SNMP dying gasp trap
The system does not try to resolve the ARP when it needs to send out the SNMP dying-gasp trap, because the amount of time available during power loss event is very less. Instead, the system assumes that ARP entry to the gateway used to reach the SNMP trap server is always available. It is recommended that user run a periodic ping query to the SNMP trap server in the background using the cron utility.
The following is an example configuration of a cron job that initiates a ping to the server mentioned in the pingscript file every one minute.

Modifying a file ID
When the file-id location parameter is modified, log files are not written to the new location until a rollover occurs or the log is manually cleared. A rollover can be forced by using the clear>log command. Subsequent log entries are then written to the new location. If a rollover does not occur or the log not cleared, the old location remains in effect.
The location can be CF (cflash-id) or USB (usb-flash-id).
Use the following CLI syntax to modify a log file ID:
config>log
file-id log-file-id
description description-string

Description
This command creates a text description stored in the configuration file for a configuration context. The description command associates a text string with a configuration context to help identify the content in the configuration file.
The no form of the command removes the string from the configuration.
Parameters
- string
The description can contain a string of up to 80 characters composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, and so on), the entire string must be enclosed within double quotes.
shutdown
Syntax
[no] shutdown
Context
config>log
config>log>accounting-policy
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command administratively disables an entity. When disabled, an entity does not change, reset, or remove any configuration settings or statistics. The operational state of the entity is disabled as well as the operational state of any entities contained within. Many objects must be shut down before they may be deleted.
The no form of this command administratively enables an entity.
Default
no shutdown
Special Cases
- log-id
When a log-id is shut down, no events are collected for the entity. This leads to the loss of event data.
- accounting-policy
When an accounting policy is shut down, no accounting data is written to the destination log ID. Counters in the billing data reflect totals, not increments, so when the policy is re-enabled (no shutdown) the counters include the data collected during the period the policy was shut down.
Event control commands
event-control
Syntax
event-control application-id [event-name | event-number] [generate [severity-level] [throttle]
event-control application-id [event-name | event-number] suppress
no event-control application [event-name | event-number]
Context
config>log
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command specifies that a particular event or all events associated with an application is either generated or suppressed.
Events are generated by an application and contain an event number and description describing the cause of the event. Each event has a default designation which directs it to be generated or suppressed.
Events are generated with a default severity level that can be modified by using the severity-level option.
Events that are suppressed by default are typically used for debugging purposes. Events are suppressed at the time the application requests the event generation. No event log entry is generated regardless of the destination. While this feature can save processor resources, there may be a negative effect on the ability to troubleshoot problems if the logging entries are squelched. In reverse, indiscriminate application may cause excessive overhead.
The rate of event generation can be throttled by using the throttle parameter.
The no form of the command reverts the parameters to the default setting for events for the application or a specific event within the application. The severity, generate, suppress, and throttle options are also reset to the initial values.
Default
Each event has a set of default settings. To display a list of all events and the current configuration use the event-control command.
Parameters
- application-id
The application whose events are affected by this event control filter.
- event-name | event-number
To generate, suppress, or revert to default for a single event, enter the specific number or event short name. If no event number or name is specified, the command applies to all events in the application. To display a list of all event short names use the event-control command.
- generate
Specifies that logger event is created when this event occurs. The generate keyword can be used with two optional parameters, severity-level and throttle.
- severity-name
An ASCII string representing the severity level to associate with the specified generated events
- throttle
Specifies whether events of this type are throttled. By default, event throttling is on for most event types.
- suppress
Indicates that the specified events are not logged. If this keyword is not specified, the events are generated by default.
route-preference
Syntax
route-preference primary {inband | outband} secondary {inband | outband | none}
no route-preference
Context
config>log
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command specifies the primary and secondary routing preference for traffic generated for SNMP notifications and syslog messages. If the remote destination is not reachable through the routing context specified by primary route preference, the secondary routing preference is attempted.
The no form of the command reverts to the default values.
Default
no route-preference
Parameters
- primary
Specifies the primary routing preference for traffic generated for SNMP notifications and syslog messages.
- secondary
Specifies the secondary routing preference for traffic generated for SNMP notifications and syslog messages. The routing context specified by the secondary route preference is attempted if the remote destination was not reachable by the primary routing preference, specified by primary route preference. The value specified for the secondary routing preference must be distinct from the value for primary route preference.
- inband
Specifies that the logging utility attempts to use the base routing context to send SNMP notifications and syslog messages to remote destinations.
- outband
Specifies that the logging utility attempts to use the management routing context to send SNMP notifications and syslog messages to remote destinations.
- none
Specifies that no attempt is made to send SNMP notifications and syslog messages to remote destinations.
Log file commands
file-id
Syntax
[no] file-id file-id
Context
config>log
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
Commands in this context configure a file ID template to be used as a destination for an event log or billing file.
This command defines the file location and characteristics that are to be used as the destination for a log event message stream or accounting/billing information. The file defined in this context is subsequently specified in the to command under log-id or accounting-policy to direct specific logging or billing source streams to the file destination.
A file ID can only be assigned to either one log-id or one accounting-policy. It cannot be reused for multiple instances. A file ID and associated file definition must exist for each log and billing file that must be stored in the file system.
A file is created when the file ID defined in this command is selected as the destination type for a specific log or accounting record. Log files are collected in a ‟log” directory. Accounting files are collected in an ‟act” directory.
The filenames for a log are created by the system as summarized in the following table.
File type |
File name |
|---|---|
Log File |
log lff-timestamp |
Accounting File |
act aaff-timestamp |
where:
ll is the log-id
aa is the accounting policy-id
ff is the file-id
The timestamp is the actual timestamp when the file is created. The format for the timestamp is yyyymmdd-hhmmss where:
yyyy is the year (for example, 2022)
mm is the month number (for example, 12 for December)
dd is the day of the month (for example, 03 for the 3rd of the month)
hh is the hour of the day in 24 hour format (for example, 04 for 4 a.m.)
mm is the minutes (for example, 30 for 30 minutes past the hour)
ss is the number of seconds (for example, 14 for 14 seconds)
The accounting file is compressed and has a .gz extension.
When initialized, each file contains the following:
the log-id description
the time the file was opened
the reason the file was created
if the event log file was closed properly, the sequence number of the last event stored on the log is recorded
If the process of writing to a log file fails (for example, the compact flash card is full) and a backup location is not specified or fails, the log file does not become operational even if the compact flash card is replaced. Enter either a clear log command or a shutdown/no shutdown command to reinitialize the file.
If the primary location fails (for example, the compact flash card fills up during the write process), a trap is sent and logging continues to the specified backup location. This can result in truncated files in different locations.
The no form of this command removes the file-id from the configuration. A file-id can only be removed from the configuration if the file is not the designated output for a log destination. The actual file remains on the file system.
Parameters
- file-id
The file identification number, expressed as a decimal integer.
location
Syntax
location [cflash-id | usb-flash-id]
no location
Context
config>log>file file-id
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command specifies the primary location where the log or billing file is created.
When creating files, the primary location is used as long as there is available space. If no space is available, an attempt is made to delete unnecessary files that are past their retention date.
If sufficient space is not available, an attempt is made to remove the oldest to newest closed log or accounting files. After each file is deleted, the system attempts to create the new file.
A medium severity trap is issued to indicate that a compact flash is either not available or that no space is available on the specified flash and that the backup location is being used.
A high priority alarm condition is raised if none of the configured compact flash devices for this file ID are present or if there is insufficient space available. If space becomes available, the alarm condition is cleared.
The no form of this command reverts to default settings.
Default
Log files are created on cf1: and accounting files are created on cf1:.
Parameters
- cflash-id
Specifies the primary location.
- usb-flash-id
Specifies the USB location.
Note:The usb-flash-id parameter is applicable only to platforms that support USB port and USB storage devices.
rollover
Syntax
rollover minutes [retention hours]
no rollover
Context
config>log
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures how often an event or accounting log is rolled over or partitioned into a new file.
An event or accounting log is actually composed of multiple individual files. The system creates a new file for the log based on the rollover time, expressed in minutes.
The retention option, expressed in hours, allows you to modify the default time to keep the file in the system. The retention time is based on the rollover time of the file.
When multiple rollover commands for a file-id are entered, the last command overwrites the previous command.
Default
rollover 1440 retention 12
Parameters
- minutes
Specifies the rollover time, in minutes.
- hours
Specifies the retention, period in hours, expressed as a decimal integer. The retention time is based on the creation time of the file. The file becomes a candidate for removal when the creation datestamp, rollover time, and retention time added together is less than the current timestamp.
Log filter commands
filter
Syntax
[no] filter filter-id
Context
config>log
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configured an event filter. An event filter specifies whether to forward or drop an event or trap based on the match criteria.
Filters are configured in the filter filter-id context and applied to a log in the log-id log-id context. Only events for the configured log source streams destined for the log ID where the filter is applied are filtered.
Any changes made to an existing filter, using any of the sub-commands, are immediately applied to the destinations where the filter is applied.
The no form of the command removes the filter association from log IDs, which causes those logs to forward all events.
Parameters
- filter-id
Specifies the filter ID.
default-action
Syntax
default-action {drop | forward}
no default-action
Context
config>log>filter
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command specifies the action that is applied to events when no action is specified in the event filter entries or when an event does not match the specified criteria. When multiple default-action commands are entered, the last command overwrites the previous command.
The no form of this command reverts the default action to the default value.
Default
default-action forward
Parameters
- drop
Specifies that the events that are not explicitly forwarded by an event filter match are dropped.
- forward
Specifies that the events that are not explicitly dropped by an event filter match are forwarded.
Log filter entry commands
action
Syntax
action {drop | forward}
no action
Context
config>log>filter>entry
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command specifies a drop or forward action associated with the filter entry. If neither drop nor forward is specified, the default-action is used for traffic that conforms to the match criteria. This could be considered a no-op filter entry used to explicitly exit a set of filter entries without modifying previous actions.
Multiple action statements entered overwrite previous actions.
The no form of this command removes the specified action statement.
Default
Action specified by the default-action command applies.
Parameters
- drop
Specifies packets matching the entry criteria are dropped.
- forward
Specifies packets matching the entry criteria are forwarded.
entry
Syntax
[no] entry entry-id
Context
config>log>filter
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command creates or edits an event filter entry. Multiple entries may be created using unique entry-id numbers. The -TiMOS implementation exits the filter on the first match found and executes the action in accordance with the action command.
Comparisons are performed in an ascending entry ID order. When entries are created, they should be arranged sequentially from the most explicit entry to the least explicit. Matching ceases when a packet matches an entry. The entry action is performed on the packet, either drop or forward. To be considered a match, the packet must meet all the conditions defined in the entry.
An entry may not have any match criteria defined (in which case, everything matches) but must have at least the keyword action for it to be considered complete. Entries without the action keyword are considered incomplete and rendered inactive.
The no form of this command removes the specified entry from the event filter. Entries removed from the event filter are immediately removed from all log IDs where the filter is applied.
Parameters
- entry-id
The entry ID uniquely identifies a set of match criteria corresponding action within a filter. Entry ID values should be configured in staggered increments so you can insert a new entry in an existing policy without renumbering the existing entries.
Log filter entry match commands
match
Syntax

Syslog commands
syslog
Syntax
[no] syslog syslog-id
Context
config>log
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
Commands in this context configure a syslog target host that is capable of receiving selected syslog messages from this network element.
A valid syslog-id must have the target syslog host address configured. A maximum of 10 syslog IDs can be configured.
No log events are sent to a syslog target address until the syslog-id has been configured as the log destination (to) in the log-id node.
The no form of this command removes the syslog configuration.
Parameters
- syslog-id
Specifies the syslog ID number for the syslog destination, expressed as a decimal integer.
address
Syntax
address ip-address
no address
Context
config>log>syslog
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command adds the syslog target host IP address to/from a syslog ID.
This parameter is mandatory. If no address is configured, syslog data cannot be forwarded to the syslog target host.
Only one address can be associated with a syslog-id. If multiple addresses are entered, the last address entered overwrites the previous address.
The same syslog target host can be used by multiple log IDs.
The no form of this command removes the syslog target host IP address.
Default
no address
Parameters
- ip-address
Specifies the IP address of the syslog target host in dotted decimal notation.
facility

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures the facility code for messages sent to the syslog target host.
Multiple syslog IDs can be created with the same target host, but each syslog ID can only have one facility code. If multiple facility codes are entered, the last facility code entered overwrites the previous facility code.
If multiple facilities need to be generated for a single syslog target host, multiple log ID entries must be created, each with its own filter criteria to select the events to be sent to the syslog target host with a specific facility code.
The no form of this command reverts to the default value.
Default
facility local7
Parameters
- syslog-facility
Specifies the syslog facility name. The syslog facility name represents a specific numeric facility code. The code should be entered in accordance with the syslog RFC. However, the software does not validate if the facility code configured is appropriate for the event type being sent to the syslog target host.

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command adds the string prepended to every syslog message sent to the syslog host.
RFC 3164, The BSD syslog Protocol, allows an alphanumeric string (tag) to be prepended to the content of every log message sent to the syslog host. This alphanumeric string can, for example, be used to identify the node that generates the log entry. The software appends a colon (:) and a space to the string and it is inserted in the syslog message after the date stamp and before the syslog message content.
Only one string can be entered. If multiple strings are entered, the last string overwrites the previous string. The alphanumeric string can contain lowercase (a-z), uppercase (A-Z), and numeric (0-9) characters.
The no form of this command removes the log prefix string.
Default
no log-prefix
Parameters
- log-prefix-string
Specifies an alphanumeric string, up to 32 characters. Spaces and colons cannot be used in the string.

Description
This command configures an event throttling rate.
Parameters
- events
Specifies the number of log events that can be logged within the specified interval for a specific event. When the limit is reached, any additional events of that type are dropped, for example, the event drop count is incremented. At the end of the throttle interval, if any events have been dropped, a trap notification is sent.
- interval seconds
Specifies the number of seconds that an event throttling interval lasts.
SNMP trap group commands
snmp-trap-group
Syntax
[no] snmp-trap-group log-id
Context
config>log
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
Commands in this context configure a group of SNMP trap receivers and their operational parameters for a specific log-id.
A group specifies the types of SNMP traps and the log ID that will receive the group of SNMP traps. A trap group must be configured for SNMP traps to be sent.
To suppress the generation of all alarms and traps, see the event-control command. To suppress alarms and traps that are sent to this log-id, see the filter command. When alarms and traps are generated, they can be directed to one or more SNMP trap groups. Logger events that can be forwarded as SNMP traps are always defined on the main event source.
The no form of this command deletes the SNMP trap group.
Parameters
- log-id
Specifies the log ID value of a log configured in the log-id context. Alarms and traps cannot be sent to the trap receivers until a valid log-id exists.
snmp-dying-gasp
Syntax
snmp-dying-gasp primary trap-target-group-num trap-target-name [secondary {trap-target-group-num trap-target-name} [tertiary {trap-target-group-num trap-target- name}]]
no snmp-dying-gasp
Context
config>log
Platforms
Supported on all 7210 SAS platforms as described in this document, except the 7210 SAS-Dxp 16p and 7210 SAS-Dxp 24p
Description
This command notifies the SNMP trap server about node power failure. On power failure, the system sends dying gasp traps to the configured SNMP trap servers. Up to three SNMP trap servers can be configured to receive the trap. The traps are sent in the following order:
primary SNMP trap receiver
Secondary SNMP trap receiver
tertiary SNMP trap receiver
When this command is enabled, the node does not generate EFM OAM dying gasp message even if EFM OAM is enabled. That is, generation of an SNMP dying gasp trap is mutually exclusive to the use of an EFM OAM dying gasp message.
By default, the system generates an EFM OAM dying gasp message to remain compatible with earlier versions of the software releases. The user must explicitly configure the system to send out an SNMP trap on loss of power to the node using this command.
Typically, SNMP traps are generated only if the user configures a log to direct the system log events to SNMP. For an SNMP dying gasp trap, it is not required to do so. The DSCP value used by a SNMP dying gasp packet is AF (Assured Forwarding class, value 22).
The system IP address must be configured. The node uses this address to generate dying gasp traps. If It is not configured, SNMP dying gasp traps are not generated.
When sending out SNMP dying gasp traps, one of the available routes in either the management routing instance or the base routing instance is used to resolve the next-hop gateway IP address to reach the trap-server destinations configured under primary, secondary, and tertiary trap targets. The route to the destination is always searched first in the management routing instance and if not found, the routes in the base routing instance is looked up. Configuration of route preference does not change this behavior (that is, the order of route lookup does not change).
The no form of this command disables generation of SNMP trap messages. It enables generation of EFM OAM dying gasp on access-uplink ports, if EFM OAM is enabled on those ports. The generation of SNMP dying gasp traps is disabled by default.
Default

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command adds or modifies a trap receiver and configures the operational parameters for the trap receiver. A trap reports significant events that occur on a network device such as errors or failures.
Before an SNMP trap can be issued to a trap receiver, the log-id, snmp-trap-group, and at least one trap-target must be configured.
The trap-target command is used to add or remove a trap receiver from an snmp-trap-group. The operational parameters specified in the command include the following:
IP address of the trap receiver
UDP port used to send the SNMP trap
SNMP version
SNMP community name for SNMPv1 and SNMPv2c receivers
security name and level for SNMPv3 trap receivers
A single snmp-trap-group log-id can have multiple trap receivers. Each trap receiver can have different operational parameters.
An address can be configured as a trap receiver more than once, as long as a different port is used for each instance.
To prevent resource limitations, only configure a maximum of 10 trap receivers.
If the same trap-target name port port parameter value is specified in more than one SNMP trap group, each trap destination should be configured with a different notify-community value. This allows a trap receiving an application, such as NMS, to reconcile a separate event sequence number stream for each 7210 SAS event log when multiple event logs are directed to the same IP address and port destination.
The no form of this command removes the SNMP trap receiver from the SNMP trap group.
Parameters
- name
Specifies the name of the trap target up to 28 characters.
- address ip-address
Specifies the IP address of the trap receiver in dotted decimal notation. Only one IP address destination can be specified per trap destination group.
- port
Specifies the destination UDP port used to send traps to the destination, expressed as a decimal integer. Only one port can be specified per trap-target statement. If multiple traps must be issued to the same address, multiple ports must be configured.
- snmpv1 | snmpv2c | snmpv3
Specifies the SNMP version format to use for traps sent to the trap receiver.
The keyword snmpv1 selects the SNMP version 1 format. When specifying snmpv1, the notify-community must be configured for the correct SNMP community string that the trap receiver expects to be present in alarms and traps messages. If the SNMP version is changed from snmpv3 to snmpv1, the notify-community parameter must be changed to reflect the community string instead of the security-name that is used by snmpv3.
The keyword snmpv2c selects the SNMP version 2c format. When specifying snmpv2c, the notify-community must be configured for the correct SNMP community string that the trap receiver expects to be present in alarms and traps messages. If the SNMP version is changed from snmpv3 to snmpv2c, the notify-community parameter must be changed to reflect the community string instead of the security-name that is used by snmpv3.
The keyword snmpv3 selects the SNMP version 3 format. When specifying snmpv3, the notify-community must be configured for the SNMP security-name. If the SNMP version is changed from snmpv1or snmpv2c to snmpv3, the notify-community parameter must be changed to reflect the security-name instead of the community string used by snmpv1 or snmpv2c.
The following pre-existing conditions are checked before the snmpv3SecurityName is accepted.
The username must be configured.
The v3 access group must be configured.
The v3 notification view must be configured.
- notify-community community | security-name
Specifies the community string for the snmpv1, snmpv2c, or snmpv3 security-name. If no notify-community is configured, no alarms nor traps are issued for the trap destination. If the SNMP version is modified, the notify-community must be changed to the correct form for the SNMP version.
- community
Specifies the community string as required by the snmpv1 or snmpv2c trap receiver. The community string can be an ASCII string up to 31 characters in length.
- security-name
Specifies the security-name as defined in the config>system>security>user context for SNMPv3. The security-name can be an ASCII string up to 31 characters.
- security-level {no-auth-no-privacy | auth-no-privacy | privacy}
Specifies the required authentication and privacy levels required to access the views configured on this node when configuring an snmpv3 trap receiver.
The keyword no-auth-no-privacy specifies that no authentication and no privacy (encryption) are required.
The keyword auth-no-privacy specifies that authentication is required, but no privacy (encryption) is required. When this option is configured the security-name must be configured for authentication.
The keyword privacy specifies that both authentication and privacy (encryption) is required. When this option is configured the security-name must be configured for authentication and privacy.
- replay
Enables replay of missed events to target. If replay is applied to an SNMP trap target address, the address is monitored for reachability. Reachability is determined by whether there is a route in the routing table by which the target address can be reached. Before sending a trap to a target address, the SNMP module asks the PIP module if there is either an in-band or out-of-band route to the target address.
If there is no route to the SNMP target address, the SNMP module saves the sequence ID of the first event that is missed by the trap target. When the routing table changes again so that there is now a route by which the SNMP target address can be reached, the SNMP module replays (for example, retransmits) all events generated to the SNMP notification log while the target address was removed from the route table.
Note:The route table changes the convergence time so it is possible that one or more events may be lost at the beginning or end of a replay sequence.
Logging destination commands
filter
Syntax
filter filter-id
no filter
Context
config>log
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command adds an event filter policy with the log destination.
This command is optional. If no event filter is configured, all events, alarms, and traps generated by the source stream are forwarded to the destination.
An event filter policy defines (limits) the events that are forwarded to the destination configured in the log ID. The event filter policy can also be used to select the alarms and traps to be forwarded to a destination snmp-trap-group.
The application of filters for debug messages is limited to application and subject only.
Accounting records cannot be filtered using the filter command.
Only one filter-id can be configured per log destination.
The no form of the command removes the specified event filter from the log-id.
Default
no filter
Parameters
- filter-id
Specifies the filter with which to associate the log-id configuration. The event filter policy ID must already be defined in config>log>filter filter-id.
from
Syntax
from {[main] [security] [change] [debug-trace]}
no from
Context
config>log
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command specifies the source stream to be sent to a log destination.
One or more source streams must be specified. The source of the data stream must be identified using the from command before you can configure the destination using the to command. The from command can identify multiple source streams in a single statement (for example, from main change debug-trace).
Only one from command may be entered for a single log-id. If multiple from commands are configured, the last command entered overwrites the previous from command.
The no form of this command removes all previously configured source streams.
Parameters
- main
Instructs all events in the main event stream to be sent to the destination defined in the to command for this destination log-id. The main event stream contains the events that are not explicitly directed to any other event stream. To limit the events forwarded to the destination, configure filters using the filter command.
- security
Instructs all events in the security event stream to be sent to the destination defined in the to command for this destination log-id. The security stream contains all events that affect attempts to breach system security such as failed login attempts, attempts to access MIB tables to which the user is not granted access or attempts to enter a branch of the CLI to which access has not been granted. To limit the events forwarded to the destination, configure filters using the filter command.
- change
Instructs all events in the user activity stream to be sent to the destination configured in the to command for this destination log-id. The change event stream contains all events that directly affect the configuration or operation of this node. To limit the events forwarded to the change stream destination, configure filters using the filter command.
- debug-trace
Instructs all debug-trace messages in the debug stream to be sent to the destination configured in the to command for this destination log-id. Filters applied to debug messages are limited to application and subject.
log-id
Syntax
[no] log-id log-id
Context
config>log
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
Commands in this context configure destinations for event streams.
The log-id context is used to direct events, alarms and traps, and debug information to respective destinations.
A maximum of 10 logs can be configured.
Before an event can be associated with this log-id, the from command identifying the source of the event must be configured.
Only one destination can be specified for a log-id. The destination of an event stream can be an in-memory buffer, console, session, snmp-trap-group, syslog, or file.
Use the event-control command to suppress the generation of events, alarms, and traps for all log destinations.
An event filter policy can be applied in the log-id context to limit which events, alarms, and traps are sent to the specified log-id.
Log IDs 99 and 100 are created by the agent. Log ID 99 captures all log messages. Log ID 100 captures log messages with a severity level of major and above.
Log ID 99 provides valuable information for the admin-tech file. Removing or changing the log configuration may hinder debugging capabilities. It is strongly recommended not to alter the configuration for log ID 99.
The no form of this command deletes the log destination ID from the configuration.

Accounting policy commands
accounting-policy
Syntax
accounting-policy policy-id
no accounting-policy policy-id
Context
config>log
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command enables an access or network accounting policy. An accounting policy defines the accounting records that are created.
Access accounting policies are policies that can be applied to one or more SAPs or access ports.
Changes made to an existing policy, using any of the sub-commands, are applied immediately to all SAPs or access ports where this policy is applied.
If an accounting policy is not specified on a SAP or an access port, accounting records are produced in accordance with the access policy designated as the default. If a default access policy is not specified, no accounting records are collected other than the records for the accounting policies that are explicitly configured.
Network accounting policies can be applied to one or more network ports. Any changes made to an existing policy, using any of the subcommands, are immediately applied to all network ports where this policy is applied.
If no accounting policy is defined on a network port, accounting records are produced in accordance with the default network policy as designated with the default command. If no network default policy is created, no accounting records are collected other than the records for the accounting policies explicitly configured.
A total of 16 accounting records are available on the 7210 SAS-D. A total of 17 accounting records are available on the 7210 SAS-Dxp.
There are three types of accounting policies:
access
access port
network
When creating accounting policies, one access, access port, and network accounting policy can be defined as default. If statistics collection is enabled on an accounting object, and no accounting policy is applied, the respective default accounting policy is used. If no default policy is defined, no statistics are collected unless a specifically defined accounting policy is applied.
The no form of this command deletes the policy from the configuration. The accounting policy cannot be removed unless it is removed from all the SAPs, network ports, or channels where the policy is applied.
Parameters
- policy-id
Specifies the policy ID that uniquely identifies the accounting policy, expressed as a decimal integer.

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures the default accounting policy to be used with all SAPs that do not have an accounting policy.
If no accounting policy is defined on an access or network object, accounting records are produced in accordance with the default access policy. If no default access policy is created, then no accounting records are collected other than the records for the accounting policies that are explicitly configured.
When creating accounting policies, one access, one access port, and one network accounting policy can be defined as default.
The record name must be specified before assigning an accounting policy as default.
If a policy is configured as the default policy, a no default command must be issued before a new default policy can be configured.
The no form of this command removes the default policy designation from the policy ID. The accounting policy is removed from all access or network object ports that do not have this policy explicitly defined.

To configure an accounting policy for access SAPs, select a service record (for example, service-ingress-octets). To change the record name to another service record, enter the record command with the new record name and it replaces the old record name.
To configure an accounting policy for access ports, select access port type records such as access-egress packets. When changing the record name to another access port record, the record command with the new record name can be entered, and it replaces the old record name.
When configuring an accounting policy for network ports, a network record should be selected. When changing the record name to another network record, the record command with the new record name can be entered and it replaces the old record name.
If the change required modifies the record from one type to another, the old record name must be removed using the no form of this command.
Only one record may be configured in a single accounting policy. For example, if an accounting-policy is configured with an access-egress-packets record, to change it to service-ingress-octets, use the no record command under the accounting-policy to remove the old record and enter the service-ingress-octets record.
Collecting excessive statistics can adversely affect the CPU utilization and take up large amounts of storage space
The no form of this command removes the record type from the policy.

Description
This command displays an event log summary with settings and statistics or the contents of a specific log file, SNMP log, or memory log.
If the command is specified with no command line options, a summary of the defined system logs is displayed. The summary includes log settings and statistics.
If the log ID of a memory, SNMP, or file event log is specified, the command displays the contents of the log. Additional command line options control what and how the contents are displayed.
Contents of logs with console, session, or syslog destinations cannot be displayed. The actual events can only be viewed on the receiving syslog or console device.
Parameters
- log-id
Displays the contents of the specified file log or memory log ID. The log ID must have a destination of an SNMP or file log or a memory log for this parameter to be used.
- severity-level
Displays only events with the specified and higher severity.
- application
Displays only events generated by the specified application.
- expression
Specifies to use a regular expression as match criteria for the router instance string.
- from-seq [to-seq]
Displays the log entry numbers from a particular entry sequence number (from-seq) to another sequence number (to-seq). The to-seq value must be larger than the from-seq value.
If the to-seq number is not provided, the log contents to the end of the log is displayed unless the count parameter is present in which case the number of entries displayed is limited by the count.
- count
Limits the number of log entries displayed to the number specified.
- router-instance
Specifies a router name up to 32 characters to be used in the display criteria.
- subject
Displays only log entries matching the specified text subject string, up to 32 characters. The subject is the object affected by the event, for example the port-id would be the subject for a link-up or link-down event.
- regexp
Specifies to use a regular expression as parameters with the specified subject string.
- ascending | descending
Specifies sort direction. Logs are normally shown from the newest entry to the oldest in descending sequence number order on the screen. When using the ascending parameter, the log are shown from the oldest to the newest entry.
