Configuring a Primary IP Address for an Interface

Configuring a Primary IP Address for an Interface

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

  3. On an Ethernet interface, run undo portswitch

    The interface is switched to Layer 3 mode.

    By default, an Ethernet interface works in Layer 2 mode.

    The mode switching function takes effect when the interface only has attribute configurations (for example, shutdown and description configurations). Alternatively, if configuration information supported by both Layer 2 and Layer 3 interfaces exists (for example, mode lacp and lacp system-id configurations), no configuration that is not supported after the working mode of the interface is switched can exist. If unsupported configurations exist on the interface, delete the configurations first and then run the undo portswitch command.

    NOTE:

    If many Ethernet interfaces need to be switched to Layer 3 mode, run the undo portswitch batch interface-type { interface-number1 [ to interface-number2 ] } &<1-10> command in the system view to switch these interfaces to Layer 3 mode in batches.

  4. Run ip address ip-address { mask | mask-length }

    A primary IP address is configured for the interface.

    Each interface has only one primary IP address. If you configure a new primary IP address for an interface, the original one is deleted and the new primary IP address takes effect.

  5. Run commit

    The configuration is committed.
