To generate linkUp or linkDown traps when the link state of an interface changes, enable the linkUp or
linkDown trap function both globally by using the snmp-agent trap enable [ standard [ linkdown |
linkup ] * ] command and on the interface by using the enable snmp trap updown command.
After you enable a trap function for a module, whether the module generates traps also depends on the
configuration of the module. For more information, see the configuration guide for each module.
To enable traps:

trap function of other
modules is enabled.

By default, the link state
traps are enabled.
Configuring the SNMP agent to send traps to a host
The SNMP module buffers the traps received from a module in a trap queue. You can set the size of the
queue, the duration that the queue holds a trap, and trap target (destination) hosts, typically the NMS.
To successfully send traps, you must also perform the following tasks:
• Complete the basic SNMP settings and verify that they are the same as on the NMS. If SNMPv1 or
SNMPv2c is used, you must configure a community name. If SNMPv3 is used, you must configure
an SNMPv3 user and MIB view.
• Make sure the device and the NMS can reach each other.
