Understanding Encapsulation over FEC or POS Channel

When configuring encapsulation over FEC or POS, be sure to configure IEEE 802.1Q on the port-channel interface, not its member ports. However, certain attributes of port channel, such as duplex mode, need to be configured at the member port levels. Also make sure that you do not apply protocol-level configuration (such as an IP address or a bridge group assignment) to the member interfaces. All protocol-level configuration should be on the port channel or on its subinterface. You must configure IEEE 802.1Q encapsulation on the partner system of the EtherChannel as well.

Configuring Encapsulation over EtherChannel or POS Channel

To configure encapsulation over the FEC or POS channel, perform the following procedure, beginning in global configuration mode:

 

Command

Purpose

Step 1

 

 

Router(config)# interface port-channel

Configures the subinterface on the created port

 

channel-number.subinterface-number

channel.

Step 2

 

 

Router(config-subif)# encapsulation dot1q

Assigns the IEEE 802.1Q encapsulation to the

 

vlan-id

subinterface.

Step 3

 

 

Router(config-subif)# bridge-group

Assigns the subinterface to a bridge group.
