Simple Network Management Protocol
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 under
“Saving the Running Configuration to a Local File”
page 681. 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 under
on page 965, a default notify filter will be
created.
Parameters
These parameters are displayed:
•
IP Address – The Internet address of a remote device. The specified target host must already
have been configured using the Administration > SNMP (Configure Trap – Add) page.
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.
•
Filter Profile Name – Notification log profile name. (Range: 1-32 characters)
Interface
To create an SNMP notification log:
1. Click Administration, SNMP.
2. Select Configure Notify Filter from the Step list.
3. Select Add from the Action list.
4. Fill in the IP address of a configured trap manager and the filter profile name.
5. Click Apply
