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.
Configuring Trap Parameters
Configuration prerequisites
To send traps to the NMS, 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 bee established between the device and the NMS, and they can operate each
other.
Configuration procedure
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:
To do… Use the command… Remarks
Enter system view system-view —
Configure target host attribute for
traps
snmp-agent target-host trap
address udp-domain { ip-address
| ipv6 ipv6-address } [ udp-port
port-number ] params
securityname security-string [ v1 |
v2c | v3 [ authentication |
privacy ] ]
Optional
To send the traps to the NMS, this
command is required, and you
must specify ip-address as the IP
address of the NMS.
