applied to each of the tunneled Layer 2 protocol types. If you also set a shutdown threshold on the interface,
the drop-threshold value must be less than or equal to the shutdown-threshold value.
When the drop threshold is reached, the interface drops Layer 2 protocol packets until the rate at which they
are received is below the drop threshold.
The configuration is saved in NVRAM.
For more information about Layer 2 protocol tunneling, see the software configuration guide for this release.
Examples
This example shows how to enable protocol tunneling for CDP packets and to configure the shutdown threshold
as 50 packets per second:
Device(config-if)# l2protocol-tunnel cdp
Device(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:
Device(config-if)# l2protocol-tunnel stp
Device(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:
Device(config-if)# l2protocol-tunnel point-to-point pagp
Device(config-if)# l2protocol-tunnel point-to-point udld
Device(config-if)# l2protocol-tunnel drop-threshold point-to-point pagp 1000
