Optional 

Enabled by default. 

 

To enable an interface to send linkUp/linkDown traps when its state changes, you need to enable the 

trap function of interface state changes on an interface and globally. Use the enable snmp trap 

updown command to enable the trap function on an interface, and use the snmp-agent trap enable 

[ standard [ linkdown | linkup ] * ] command to enable this function globally. 

 

To send traps to the NMS, you need to make the following preparations: 

z 

Basic SNMP configurations have been completed. These configurations include version 

configuration: community name is needed when SNMPv1 and v2c are adopted; username and MIB 

view are needed if SNMPv3 is adopted. 

z 

A connection has been established between the device and the NMS, and they can operate each 

other. 

After traps are sent to the SNMP module, the SNMP module saves the traps in the trap queue. You can 

set the size of the queue and the holding time of the traps in the queue, and you can also send the traps 

to the specified destination host (usually the NMS). 

Follow these steps to configure trap parameters:
