Why Does a Device Fail to Report Interface Up/Down Traps to the NMS and How Can I Disable the Up/Down Traps of a Specified Interface?
By default, the interface status trap function is globally disabled.
Therefore, when an interface changes status, no trap is generated.
Run the snmp-agent trap enable feature-name ifnet trap-name { linkdown | linkup } command
to enable the interface status trap function globally. When interface
status frequently changes, a large number of traps are sent to the
NMS, increasing the load on the NMS. In this situation, you can disable
the interface status trap function. The procedure is as follows:
- Run the interface interface-type interface-number command to enter the interface view.
- Run the undo enable snmp trap updown command to disable the interface status trap function.
The following example shows how to disable the device from sending traps to the NMS when any interface changes its status to Up.

The following example shows how to disable the device from sending traps to the NMS when GE1/0/1 changes its status.
