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, when the switch reboots, some
SNMP traps (such as warm start) cannot be logged.
â—† To avoid this problem, notification logging should be configured as
described in this section, and these commands stored in the startup
configuration file using the System > File (Copy – Running-Config)
page as described on page 124. Then when the switch reboots, SNMP
traps (such as warm start) can now be logged.
â—† Based on the default settings used in RFC 3014, a notification log can
contain up to 256 entries, and the entry aging time is 1440 minutes.
Information recorded in a notification log, and the entry aging time can
only be configured using SNMP from a network management station.
â—† When a trap host is created using the Administration > SNMP
(Configure Trap – Add) page described on page 466, a default notify
filter will be created.

This remote host parameter is only required to complete mandatory
fields in the SNMP Notification MIB.
◆ Filter Profile Name – Notification log profile name. (Range: 1-32
characters)
