Configuring IEEE 802.1Q and Layer 2 Protocol Tunneling

Configuring the SP Edge Switch

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

switchport mode dot1q-tunnel

Configures the interface as an IEEE 802.1Q tunnel port.

 

Example:

 

 

 

Switch(config-if)# switchport mode

 

 

 

dot1q-tunnel

 

 

Step 4

l2protocol-tunnel point-to-point [pagp lacp

(Optional) Enables point-to-point protocol tunneling for the desired

 

udld]

protocol. If no keyword is entered, tunneling is enabled for all three

 

 

protocols.

 

Example:

Note

To avoid a network failure, make sure that the network is a

 

Switch(config-if)# l2protocol-tunnel

 

point-to-point topology before you enable tunneling for PAgP,

 

 

LACP, or UDLD packets.

 

point-to-point pagp

 

 

 

Note

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.

Step 5

l2protocol-tunnel shutdown-threshold

 

[point-to-point [pagp lacp udld]] value

Example:

Switch(config-if)# l2protocol-tunnelshutdown-thresholdpoint-to-point pagp

100

(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

[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.

Step 6

l2protocol-tunnel drop-threshold

(Optional) Configures the threshold for packets-per-second accepted

 

[point-to-point [pagp lacp udld]] value

for encapsulation. The interface drops packets if the configured threshold
