Enabling Link-Change Traps (CLI)

By default, a switch is enabled to send a trap when the link state on a port changes from up to down (linkDown) or down to up (linkUp). To reconfigure the switch to send link-change traps to configured trap receivers, enter the snmp-server enable traps link-change command.

Syntax:

[no] snmp-server enable traps link-change <port-list> [all]

Enables or disables the switch to send a link-change trap to configured trap receivers when the link state on a port goes from up to down or down to up.

Enter all to enable or disable link-change traps on all ports on the switch.
