Configuring 802.1Q VLAN Interfaces
• Replace the interface-path-id argument with one of the following 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.
• You must include the l2transport keyword in the command string; otherwise, the configuration creates a Layer 3
subinterface rather that an AC.
Step 3 encapsulation dot1q 100
Example:
RP/0//CPU0:router (config-subif)# encapsulation dot1q 100
Sets the Layer 2 encapsulation of an interface.
The dot1q vlan command is replaced by the encapsulation dot1q command. It is still available for
Note
backward-compatibility, but only for Layer 3 interfaces.
Step 4 end or commit
Example:
RP/0//CPU0:router(config-if-l2)# end
or
RP/0//CPU0:router(config-if-l2)# commit
Saves configuration changes.
• When you issue the end command, the system prompts you to commit changes:
Uncommitted changes found, commit them before exiting(yes/no/cancel)?
[cancel]:
- Entering yes saves configuration changes to the running configuration file, exits the configuration session, and
returns the router to EXEC mode.
- Entering no exits the configuration session and returns the router to EXEC mode without committing the
configuration changes.
- Entering cancel leaves the router in the current configuration session without exiting or committing the configuration
changes.
• Use the commit command to save the configuration changes to the running configuration file and remain within
the configuration session.
Step 5 show interfaces [GigabitEthernet |FortyGigE|Bundle-Ether | TenGigE] interface-path-id.subinterface
Example:
RP/0//CPU0:router# show interfaces TenGigE 0/3/0/0.1
(Optional) Displays statistics for interfaces on the router.
