Defining the Encapsulation for the Layer 2 Switching TCCs

To begin configuring a Layer 2 switching TCC, configure the TCC encapsulation on the desired interfaces of the router that is acting as the switch.

Note: You cannot configure standard protocol families on TCC or CCC interfaces. Only the CCC family is allowed on CCC interfaces, and only the TCC family is allowed on TCC interfaces.

You can configure the following types of circuits and encapsulations:

• PPP and Cisco HDLC Encapsulation for Layer 2 Switching TCCs
• ATM Encapsulation for Layer 2 Switching TCCs
• Frame Relay Encapsulation for Layer 2 Switching TCCs
• Ethernet Encapsulation for Layer 2 Switching TCCs
• Ethernet Extended VLAN Encapsulation for Layer 2 Switching TCCs
• ARP Configuration for Ethernet TCC Encapsulations

For Ethernet circuits and Ethernet extended VLAN circuits, you also need to configure the Address Resolution Protocol (ARP). See ARP Configuration for Ethernet TCC Encapsulations.
