Configuration restrictions and guidelines

When you bulk configure interfaces in interface range view, follow these restrictions and guidelines:

• In interface range view, only commands supported by the first interface in the specified interface list are available for configuration.

• Before you configure an interface as the first interface in an interface range, make sure you can enter the view of the interface by using the interface interface-type { interface-number | interface-number.subnumber } command.

• Do not assign both an aggregate interface and any of its member interfaces to an interface range. Some commands, after being executed on both an aggregate interface and its member interfaces, can break up the aggregation.

• Understand that the more interfaces you specify, the longer the command execution time.

• To guarantee bulk interface configuration performance, configure fewer than 1000 interface range names.

• After a command is executed in interface range view, one of the following situations might occur:

  • The system displays an error message and stays in interface range view. It means that the execution failed on one or multiple member interfaces.

    • If the execution failed on the first member interface, the command is not executed on any member interfaces.

    • If the execution failed on a non-first member interface, the command takes effect on the remaining member interfaces.

  • The system returns to system view. It means that:

    • The command is supported in both system view and interface view.

    • The execution failed on a member interface in interface range view and succeeded in system view.

    • The command is not executed on the subsequent member interfaces.

    You can use the display this command to verify the configuration in interface view of each member interface. In addition, if the configuration in system view is not needed, use the undo form of the command to remove the configuration.
