L2-Circuit Tunnel

L2-Circuit tunnel is a type of tunnel that uses circuit-ID to encapsulate the traffic. These tunnels are bidirectional. For details about the L2-Circuit tunnels, refer to the “About Circuit-ID Tunnels” section in the GigaVUE Fabric Management Guide.

Configure L2-Circuit Tunnel for Encapsulation

Create an L2-Circuit tunnel for encapsulation using the tunnel command, which has the following syntax:

tunnel alias <alias> encap l2-circuit
   circuit-id <value> => value between 2 to 4000>

The following table describes the arguments for the L2-Circuit tunnel for encapsulation using the tunnel command:

Argument

Description

tunnel alias <alias> encap l2-circuit

Specifies an alias for the circuit tunnel. The alias must be unique and can contain up to 128 characters. Aliases are case-sensitive.

Also, specify the mode as encap and the type as l2-circuit.

For example:

(config) # tunnel alias <alias> encap l2-circuit

circuit-id <value> => value between 2 to 4000>

Specifies the circuit-ID used to encapsulate the traffic. The valid range is 2–4000.

For example:

(config tunnel alias <alias> encap l2-circuit) # circuit-id 2000

Note:  Use this encap tunnel in the map configuration to encapsulate the traffic with l2-circuit-id tunnel and send the traffic to the circuit tool ports of the map.

Configure L2-Circuit Tunnel for Decapsulation

Create an L2-Circuit tunnel for decapsulation using the tunnel command, which has the following syntax:

tunnel alias <alias> decap l2-circuit
   circuit-id <value/range> // Range is value1,value2,value3
   attach <circuit-port-list / circuit-gigastream>

The following table describes the arguments for the L2-Circuit tunnel for decapsulation using the tunnel command:

Argument

Description

tunnel alias <alias> decap l2-circuit

Specifies an alias for the circuit tunnel. The alias must be unique and can contain up to 128 characters. Aliases are case-sensitive.

Also, specify the mode as decap and the type as l2-circuit.

For example:

(config) # tunnel alias <alias> decap l2-circuit

circuit-id <value/range> // Range is value1,value2,value3

Specifies the circuit-ID used to encapsulate the traffic. The valid range is 2–4000.

For example:

(config tunnel alias <alias> decap l2-circuit) # circuit-id 100,200,300

attach <circuit-port-list / circuit-gigastream>

Specifies the circuit ports or circuit GigaStream to be attached with the circuit tunnel.

For example:

(config tunnel alias <alias> decap l2-circuit) # attach <circuit-port-list>
