This topic describes how to remove a previously configured 802.1Q VLAN subinterface on the Cisco 8000 Series Router.

Use this procedure to remove 802.1Q VLAN subinterfaces that have been previously configured using the Configure 802.1Q VLAN subinterfaces task in this module.

Procedure

  1. Enter global configuration mode.

    Example:

    Router# configure

  2. Remove the subinterface, which also automatically deletes all the configuration applied to the subinterface.

    Example:

    Router(config)# no interface TenGigE 0/2/0/4.10

    • Replace the instance 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.

    Note

    Repeat this step to remove other VLAN subinterfaces.

  3. Save the configuration.

    Example:

    Router(config)# commit

    Use the commit command to save the configuration changes to the running configuration file and remain within the configuration session. When you issue the end command, the system prompts you to commit changes.
