◆ 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.
◆ When this command is executed, a notification log is created (with the
default parameters defined in RFC 3014). Notification logging is
enabled by default (see the nlm command), but will not start recording
information until a logging profile specified with this command is
enabled with the nlm command.
◆ 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.
◆ When a trap host is created with the snmp-server host command, a
default notify filter will be created as shown in the example under the
show snmp notify-filter command.
EXAMPLE
This example first creates an entry for a remote host, and then instructs
the switch to record this device as the remote host for the specified
notification log.
