Notification Log Commands
– 196 –
Example
This example enables the notification log A1.
Console(config)#nlm A1
Console(config)#
snmp-server
notify-filter
This command creates an SNMP notification log. Use the no form to remove this
log.
Syntax
[no] snmp-server notify-filter profile-name remote ip-address
profile-name - Notification log profile name. (Range: 1-32 characters)
ip-address - IPv4 or IPv6 address of a remote device. The specified target
host must already have been configured using the snmp-server host
command.
Note:
The notification log is stored locally. It is not sent to a remote device. This
remote host parameter is only required to complete mandatory fields in the SNMP
Notification MIB.
Default Setting
None
Command Mode
Global Configuration
Command Usage
â—† Systems that support SNMP often need a mechanism for recording Notification
information as a hedge against lost notifications, whether there are Traps or
Informs that may exceed retransmission limits. The Notification Log MIB (NLM,
RFC 3014) provides an infrastructure in which information from other MIBs may
be logged.
â—† Given the service provided by the NLM, individual MIBs can now bear less
responsibility to record transient information associated with an event against
the possibility that the Notification message is lost, and applications can poll
the log to verify that they have not missed any important Notifications.
â—† If notification logging is not configured and enabled, when the switch reboots,
some SNMP traps (such as warm start) cannot be logged.
â—† To avoid this problem, notification logging should be configured and enabled
using the snmp-server notify-filter command and nlm command, and these
commands stored in the startup configuration file. Then when the switch
reboots, SNMP traps (such as warm start) can now be logged.
