Configuring IEEE 802.1Q and Layer 2 Protocol Tunneling

Configuring Layer 2 Protocol Tunneling

DETAILED STEPS

 

Command or Action

Purpose

Step 1

configure terminal

Enters the global configuration mode.

Example:

Switch# configure terminal

Step 2

interface interface-id

Specifies the interface connected to the phone, and enters interface

 

 

configuration mode.

 

Example:

 

 

Switch(config)# interface

 

 

gigabitethernet1/0/1

 

Step 3

Use one of the following:

Configures the interface as an access port or an IEEE 802.1Q tunnel port.

•switchport mode access

•switchport mode dot1q-tunnel

Example:

Switch# switchport mode access or

Switch# switchport mode dot1q-tunnel

Step 4

l2protocol-tunnel [cdp lldp point-to-point

Enables protocol tunneling for the desired protocol. If no keyword is

 

stp vtp]

entered, tunneling is enabled for all three Layer 2 protocols.

 

Example:

Note

Use the no l2protocol-tunnel [cdp lldp point-to-point stp

 

 

vtp] interface configuration command to disable protocol

 

Switch# l2protocol-tunnel cdp

 

tunneling for one of the Layer 2 protocols or for all three.

 

 

 

Step 5 l2protocol-tunnel shutdown-threshold [

packet_second_rate_value cdp lldp

point-to-point stp vtp]

Example:

Switch# l2protocol-tunnel shutdown-threshold 100 cdp

(Optional) Configures 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.

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

drop-threshold value.

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