Configuring Up/Down SNMP Link-State Traps for Interfaces

By default, SNMP link-state traps are enabled for all interfaces. Whenever a link toggles its state from
Up to Down or vice versa, an SNMP trap is generated.
In some instances, you may find that you have numerous switches with hundreds of interfaces, many of
which do not require monitoring of the link state. In such cases, you may elect to disable link-state traps.
To disable SNMP link-state traps for specific interfaces, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# interface bay 6
switch(config-if)# no link-state-trap
switch(config-if)# link-state-trap
Whenever you disable an SNMP link-state trap for an interface, the command is also added to the
running configuration of the system. To view the running configuration, enter the show running-config
command for the interface.
switch# show running-config
version 3.1(2)
