The Carrier Ethernet Model
RP/0/RSP0/CPU0:router(config)# interface TenGigE 0/2/0/4.10
Enters subinterface configuration mode and specifies the interface type, location, and subinterface number.
• Replace the instance argument with one of these instances:
• Physical Ethernet interface instance, or with an Ethernet bundle instance. Naming notation is
rack/slot/module/port, and a slash between values is required as part of the notation.
• Ethernet bundle instance. Range is from 1 through 65535.
• Replace the subinterface argument with the subinterface value. Range is from 0 through 4095.
• Naming notation is instance.subinterface, and a period between arguments is required as part of the notation.
Step 3
l2transport
Example:
RP/0/RSP0/CPU0:router(config-subif)# l2transport
Enables Layer 2 transport mode on a port and enter Layer 2 transport configuration mode.
Step 4 encapsulation dot1q vlan-id
Example:
RP/0/RSP0/CPU0:router(config-subif-l2)# encapsulation dot1q 100
Assigns a VLAN Attachment Circuit to the subinterface.
• Replace the vlan-id argument with a subinterface identifier. Range is from 1 to 4094 inclusive (0 and 4095 are
reserved). To configure a basic Dot1Q Attachment Circuit, use this syntax:
encapsulation dot1q vlan-id
• To configure a QinQ Attachment Circuit, use this syntax:
encapsulation dot1q vlan-id second-dot1q vlan-id
Note Following are the varieties of encapsulation commands:
• encapsulation dot1q 100
• encapsulation dot1q 100 second-dot1q 101
• encapsulation dot1ad 200 dot1q 201
Step 5 Use the commit or end command.
commit - Saves the configuration changes and remains within the configuration session.
end - Prompts user to take one of these actions:
• Yes - Saves configuration changes and exits the configuration session.
• No - Exits the configuration session without committing the configuration changes.
• Cancel - Remains in the configuration mode, without committing the configuration changes.
