29.1.1 Layer 2 Protocol Tunneling Mode

Each port can have two layer 2 protocol tunneling modes, Access and Tunnel.

•The Access port is an ingress port on the service provider's edge device (1 or 2 in Figure 151 on page 304) and connected to a customer switch (A or B). Incoming layer 2 protocol packets received on an access port are encapsulated and forwarded to the tunnel ports.

•The Tunnel port is an egress port at the edge of the service provider's network and connected to another service provider’s switch. Incoming encapsulated layer 2 protocol packets received on a tunnel port are decapsulated and sent to an access port.
