Creating SNMP Notification Logs
Use the Administration > SNMP (Configure Notify Filter - Add) page to create an SNMP notification log.
Command Usage
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 be exceeding retransmission limits. The Notification Log MIB
(NLM, RFC 3014) provides an infrastructure in which information from other MIBs may be logged.
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.
If notification logging is not configured, when the switch reboots, some SNMP traps (such as warm start) cannot be
logged.
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 43. Then when
the switch reboots, SNMP traps (such as warm start) can now be logged.
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 using the Administration > SNMP (Configure Trap - Add) page described on page 218, a default
notify filter will be created.
The following table lists the options on this page:

Administration - SNMP Options
IP Address
The IPv4 or IPv6 address of a remote device. The specified target host must already have been
configured using the Administration > SNMP (Configure Trap - Add) page.
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.
