Enter the drop-threshold keyword to control the number of protocol packets per second that are received
on an interface before it drops packets. When no protocol option is specified with a keyword, the
threshold is 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:
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
