Examples
This example shows how to enable protocol tunneling for CDP packets and to configure the shutdown
threshold as 50 packets per second:
Switch(config-if)# l2protocol-tunnel cdp
Switch(config-if)# l2protocol-tunnel shutdown-threshold cdp 50
This example shows how to enable protocol tunneling for STP packets and to configure the drop
threshold as 400 packets per second:
Switch(config-if)# l2protocol-tunnel stp
Switch(config-if)# l2protocol-tunnel drop-threshold stp 400
This example shows how to enable point-to-point protocol tunneling for PAgP and UDLD packets and
to configure the PAgP drop threshold as 1000 packets per second:
Switch(config-if)# l2protocol-tunnel point-to-point pagp
Switch(config-if)# l2protocol-tunnel point-to-point udld
Switch(config-if)# l2protocol-tunnel drop-threshold point-to-point pagp 1000
