Use the no l2protocol-tunnel [point-to-point [pagp | lacp | udld]] interface configuration command to
disable point-to-point protocol tunneling for one of the Layer 2 protocols or for all three. Use the no
l2protocol-tunnel shutdown-threshold [point-to-point [pagp | lacp | udld]] and the no
l2protocol-tunnel drop-threshold [[point-to-point [pagp | lacp | udld]] commands to return the
shutdown and drop thresholds to the default settings.

Purpose
(Optional) Configure the threshold for packets-per-second accepted for
encapsulation. The interface is disabled if the configured threshold is
exceeded. If no protocol option is specified, the threshold applies to each of
the tunneled Layer 2 protocol types. The range is 1 to 4096. The default is
to have no threshold configured.
If you also set a drop threshold on this interface, the
Note
shutdown-threshold value must be greater than or equal to the
drop-threshold value.
(Optional) Configure the threshold for packets-per-second accepted for
encapsulation. The interface drops packets if the configured threshold is
exceeded. If no protocol option is specified, the threshold applies to each of
the tunneled Layer 2 protocol types. The range is 1 to 4096. The default is
to have no threshold configured.
If you also set a shutdown threshold on this interface, the
Note
drop-threshold value must be less than or equal to the
shutdown-threshold value.
Disable CDP on the interface.
Enable BPDU filtering on the interface.
Return to global configuration mode.
maximum-rate error so that the interface is re-enabled and can try again.
Errdisable recovery is disabled by default; when enabled, the default time
interval is 300 seconds.
(Optional) Configure the CoS value for all tunneled Layer 2 PDUs. The
range is 0 to 7; the default is the default CoS value for the interface. If none
is configured, the default is 5.
Return to privileged EXEC mode.
Display the Layer 2 tunnel ports on the switch, including the protocols
configured, the thresholds, and the counters.
(Optional) Save your entries in the configuration file.
