    Adding a Description to an IPv6 Interface or Subinterface

    The router enables you to add a text description or an alias to an IPv6 interface or subinterface. Adding a description helps you identify the interface and keep track of interface connections. The description or alias can be a maximum of 256 characters.

    Note:

    • Before you configure IPv6, you must create the lower-layer interfaces over which IPv6 traffic flows.
    • You must configure an IPv6 license using the license ipv6 command before using the IPv6 routing protocol configuration commands on the E Series router.
    • All IPv6 routing protocol configurations are removed from the virtual router when you issue the no ipv6 command.
    • You can use this command in Subinterface Configuration mode.

    To assign a text description or an alias to an IPv6 interface:

    • Issue the ipv6 description command in Interface Configuration mode.
      host1(config-if)#ipv6 description boston01 ipv6 interface

    To assign a text description or an alias to an IPv6 subinterface:

    • Issue the ipv6 description command in Subinterface Configuration mode.
      host1(config-subif)#ipv6 description dallas05 ipv6 subinterface

    Use the no version to remove the text description or alias.
