Configuring IEEE 802.1Q and Layer 2 Protocol Tunneling

Configuring Layer 2 Protocol Tunneling

Command or Action

Step 6 l2protocol-tunnel drop-threshold [

packet_second_rate_value cdp lldp

point-to-point stp vtp]

Example:

Switch# l2protocol-tunnel drop-threshold 100 cdp

Step 7

exit

Example:

Switch# exit

Purpose

(Optional) Configures 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.

Note If you also set a shutdown threshold on this interface, the drop-thresholdvalue must be less than or equal to the shutdown-thresholdvalue.

Note Use the no l2protocol-tunnel shutdown-threshold [cdp lldp

point-to-point stp vtp] and the no l2protocol-tunnel drop-threshold [cdp stp vtp] commands to return the shutdown and drop thresholds to the default settings.

Returns to global configuration mode.

Step 8 errdisable recovery cause l2ptguard

Example:

Switch(config)# errdisable recovery cause l2ptguard

(Optional) Configures the recovery mechanism from a Layer 2 maximum-rate error so that the interface is reenabled and can try again. Errdisable recovery is disabled by default; when enabled, the default time interval is 300 seconds.

Step 9

l2protocol-tunnel cos value

(Optional) Configures 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

 

Example:

none is configured, the default is 5.

 

Switch(config)# l2protocol-tunnel cos

 

 

value 7

 

Step 10

end

Returns to privileged EXEC mode.

Example:

Switch(config)# end

Step 11

show l2protocol

Displays the Layer 2 tunnel ports on the switch, including the protocols

 

 

configured, the thresholds, and the counters.

 

Example:

 

 

Switch# show l2protocol

 

Step 12

copy running-config startup-config

(Optional) Saves your entries in the configuration file.

 

Example:

 

 

Switch# copy running-config
