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.

Configuring the Customer Switch

After configuring the SP edge switch, begin in privileged EXEC mode and follow these steps to
configure a customer switch for Layer 2 protocol tunneling for EtherChannels:
Command
Step 1 configure terminal
Step 2
interface interface-id
Step 3
no shutdown
Step 4
switchport mode trunk
Step 5 udld enable
78-17058-01
Purpose
(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.
If the interface is an NNI, disable CDP on the interface. UNIs do not support
CDP.
If the interface is an NNI, enable BPDU filtering on the interface. UNIs do
not support STP PBDU filtering.
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.
Purpose
Enter global configuration mode.
Enter the interface configuration mode. This should be the customer switch
port.
Enable the port, if necessary. By default, UNIs are disabled and NNIs are
enabled.
Enable trunking on the interface.
Enable UDLD in normal mode on the interface.
