Understanding Encapsulation over EtherChannel or POS
Channel
When configuring encapsulation over FEC, GEC, 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 EtherChannel or POS channel, perform the following procedure,
beginning in global configuration mode:
Command
Step 1
Router(config)# interface port-channel
channel-number.subinterface-number
Step 2
Router(config-subif)# encapsulation dot1q
vlan-id
Step 3
Router(config-subif)# bridge-group
bridge-group-number
