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).
•
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 displays a log configuration example.
A:ALA-12>config>log# info
#------------------------------------------
echo "Log Configuration "
#------------------------------------------
        event-control "bgp" 2001 generate critical
        file-id 1
            description "This is a test file-id."
            location cf1:
        exit
        file-id 2
            description "This is a test log."
            location cf1:
        exit
        snmp-trap-group 7
            trap-target 11.22.33.44 "snmpv2c" notify-community "public"
        exit
        log-id 2
            from main
            to file 2
        exit
----------------------------------------------
A:ALA-12>config>log#
 
Common Configuration Tasks
The following sections are basic system tasks that must be performed.
•
Configuring a File ID
•
Configuring an Event Log
•
Configuring an Accounting Policy
•
Configuring Event Control
•
Configuring a Log Filter
•
Configuring an SNMP Trap Group
•
Configuring a Syslog Target
 
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:
CLI Syntax: config>log
log-id log-id
description description-string
filter filter-id
from {[main] [security] [change] [debug-trace]}
to console
to file file-id
to memory [size]
to session
to snmp [size]
to syslog syslog-id}
time-format {local|utc}
no shutdown
 
 
 
 
 
The following displays a log file configuration example:
ALA-12>config>log>log-id# info
----------------------------------------------
...
	log-id 2
            description "This is a test log file."
            filter 1
            from main security
            to file 1
	exit
...
----------------------------------------------
ALA-12>config>log>log-id#
 
Configuring a File ID
To create a log file a file ID is defined, specifies the target CF drive, and the rollover and retention interval period for the file. The rollover interval is defined in minutes and determines how long a file will be used before it is closed and a new log file is created. The retention interval determines how long the file will be stored on the CF before it is deleted.
Use the following CLI syntax to configure a log file:
CLI Syntax: config>log
file-id log-file-id
description description-string
location cflash-id [backup-cflash-id]
rollover minutes [retention hours]
 
The following displays a log file configuration example:
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: or cf2:) 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.
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 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.
Use the following CLI syntax to configure an accounting policy:
CLI Syntax: config>log
accounting-policy acct-policy-id interval minutes
description description-string
default
record record-name
to file log-file-id
no shutdown
 
The following displays a accounting policy configuration example:
A:ALA-12>config>log# info
----------------------------------------------
	accounting-policy 4
		description "This is the default accounting policy."
		record complete-service-ingress-egress
		default
		to file 1
	exit
	accounting-policy 5
		description "This is a test accounting policy."
		record service-ingress-packets
		to file 3
	exit
----------------------------------------------
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.
CLI Syntax: config>log
event-control application-id [event-name|event-number] generate [severity-level] [throttle]
event-control application-id [event-name|event-number] suppress
throttle-rate events [interval seconds]
 
The following displays an event control configuration:
A:ALA-12>config>log# info
#------------------------------------------
echo "Log Configuration"
#------------------------------------------
        throttle-rate 500 interval 10
        event-control "oam" 2001 generate throttle
        event-control "ospf" 2001 suppress
        event-control "ospf" 2003 generate cleared
        event-control "ospf" 2014 generate critical
..
----------------------------------------------
A:ALA-12>config>log>filter#
 
 
Configuring Throttle Rate
This command configures the number of events and interval length to be applied to all event types that have throttling enabled by the event-control command.
Use the following CLI syntax to configure the throttle rate.
CLI Syntax: config>log#
throttle-rate events [interval seconds]
 
The following displays a throttle rate configuration example:
*A:gal171>config>log# info
---------------------------------------------
        throttle-rate 500 interval 10
        event-control "bgp" 2001 generate throttle
----------------------------------------------
*A:gal171>config>log#
 
Configuring a Log Filter
The following displays a log filter configuration example:
A:ALA-12>config>log# info
#------------------------------------------
echo "Log Configuration "
#------------------------------------------
        file-id 1
            description "This is our log file."
            location cf1:
            rollover 600 retention 24
        exit
        filter 1
            default-action drop
            description "This is a sample filter."
            entry 1
                action forward
                match
                    application eq "mirror"
                    severity eq critical
                exit
            exit
        exit
...
log-id 2
            shutdown
            description "This is a test log file."
            filter 1
            from main security
            to file 1
        exit
...
------------------------------------------
A:ALA-12>config>log#
 
Configuring an SNMP Trap Group
The associated log-id does not have to configured before a snmp-trap-group can be created, however, the snmp-trap-group must exist before the log-id can be configured to use it.
The following displays a basic SNMP trap group configuration example:
A:ALA-12>config>log# info
----------------------------------------------
...
snmp-trap-group 2
trap-target 10.10.10.104:5 "snmpv3" notify-community "coummunitystring"
exit
...
	log-id 2
            description "This is a test log file."
            filter 1
            from main security
            to file 1
	exit
...
----------------------------------------------
A:ALA-12>config>log#
 
The following displays a SNMP trap group, log, and interface configuration examples:
A:SetupCLI>config>log# snmp-trap-group 44
A:SetupCLI>config>log>snmp-trap-group# info
----------------------------------------------
            trap-target "xyz-test" address xx.xx.x.x snmpv2c notify-community "xyztesting"
            trap-target "test2" address xx.xx.xx.x snmpv2c notify-community "xyztesting"
----------------------------------------------
*A:SetupCLI>config>log>log-id# info
----------------------------------------------
            from main
            to snmp
----------------------------------------------
*A:SetupCLI>config>router# interface xyz-test
*A:SetupCLI>config>router>if# info
----------------------------------------------
            address xx.xx.xx.x/24
            port 1/1/1
----------------------------------------------
*A:SetupCLI>config>router>if#
 
 
Setting the Replay Parameter
For this example the replay parameter was set by a SNMP SET request for the trap-target address 10.10.10.3 which is bound to port-id 1/1/1.
A:SetupCLI>config>log>snmp-trap-group 44
A:SetupCLI>config>log>snmp-trap-group# info
----------------------------------------------
            trap-target "xyz-test" address 10.10.10.3 snmpv2c notify-community "xyztesting" replay
            trap-target "test2" address 20.20.20.5 snmpv2c notify-community "xyztesting"
----------------------------------------------
A:SetupCLI>config>log>snmp-trap-group#
 
In the following output, note that the Replay field changed from disabled to enabled.

Shutdown In-Band Port
A shutdown on the in-band port that the trap-target address is bound to causes the route to that particular trap target to be removed from the route table. When the SNMP module is notified of this event, it marks the trap-target as inaccessible and saves the sequence-id of the first SNMP notification that will be missed by the trap-target.
Example: config>log>snmp-trap-group# exit all
#configure port 1/1/1 shutdown
#
# tools perform log test-event
#
The Replay from field is updated with the sequence-id of the first event that will be replayed when the trap-target address is added back to the route table.

No Shutdown Port
A no shutdown command executed on the in-band port to which the trap-target address is bound will cause the route to that trap target to be re-added to the route table. When the SNMP trap module is notified of this event, it resends the notifications that were missed while there was no route to the trap-target address.
Example: configure# port 1/1/1 no shutdown
#
# tools perform log test-event
After the notifications have been replayed the Replay from field indicates n/a because there are no more notifications waiting to be replayed and the Last replay field timestamp has been updated.

Modifying a Log File
Use the following CLI syntax to modify a log file:
CLI Syntax: config>log
log-id log-id
description description-string
filter filter-id
from {[main] [security] [change] [debug-trace]}
to console
to file file-id
to memory [size]
to session
to snmp [size]
to syslog syslog-id}
The following displays the current log configuration:
ALA-12>config>log>log-id# info
----------------------------------------------
...
	log-id 2
            description "This is a test log file."
            filter 1
            from main security
            to file 1
	exit
...
----------------------------------------------
ALA-12>config>log>log-id#
 
 
The following displays an example to modify log file parameters:
Example: config# log
config>log# log-id 2
config>log>log-id# description "Chassis log file."
config>log>log-id# filter 2
config>log>log-id# from security
config>log>log-id# exit
The following displays the modified log file configuration:
A:ALA-12>config>log# info
----------------------------------------------
...
	log-id 2
            description "Chassis log file."
            filter 2
            from security
            to file 1
	exit
...
----------------------------------------------
A:ALA-12>config>log#
 
Deleting a Log File
The log ID must be shutdown first before it can be deleted. In a previous example, file 1 is associated with log-id 2. 
A:ALA-12>config>log# info
----------------------------------------------
	file-id 1
            description "LocationTest."
            location cf1:
            rollover 600 retention 24
        exit
...
	log-id 2
            description "Chassis log file."
            filter 2
            from security
            to file 1
	exit
...
----------------------------------------------
A:ALA-12>config>log#
 
 
Use the following CLI syntax to delete a log file:
CLI Syntax: config>log
no log-id log-id
shutdown
The following displays an example to delete a log file:
Example: config# log
config>log# log-id 2
config>log>log-id# shutdown
config>log>log-id# exit
config>log# no log-id 2
 
Modifying a File ID
NOTE: 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.
Use the following CLI syntax to modify a log file:
CLI Syntax: config>log
file-id log-file-id
description description-string
location [cflash-id] [backup-cflash-id]
rollover minutes [retention hours]

            rollover 600 retention 24
        exit
----------------------------------------------
A:ALA-12>config>log#
 
The following displays an example to modify log file parameters:
Example: config# log

config>log>file-id# exit
The following displays the file modifications:
A:ALA-12>config>log# info
----------------------------------------------
...
file-id 1
            description "LocationTest."
            location cf2:
            rollover 2880 retention 500
exit
