You can extend standard linkUp/linkDown notifications to include interface description and interface
type, but must make sure the NMS supports the extended SNMP messages.
To send informs, make sure:
•
The SNMP agent and the NMS use SNMPv2c or SNMPv3.
•
If SNMPv3 is used, you must configure the SNMP engine ID of the NMS when you configure
SNMPv3 basic settings. Also, specify the IP address of the SNMP engine when you create the
SNMPv3 user.
Configuration prerequisites
Configure the SNMP agent with the same basic SNMP settings as the NMS. If SNMPv1 or SNMPv2c is
used, you must configure a community name. If SNMPv3 is used, you must configure an SNMPv3 user,
a MIB view, and a remote SNMP engine ID associated with the SNMPv3 user for notifications.
Make sure the SNMP agent and the NMS can reach each other.
