Bulk configuring interfaces

You can enter interface range view to bulk configure multiple interfaces with the same feature instead of configuring them one by one. For example, you can execute the shutdown command in interface range view to shut down a range of interfaces.

Configuration restrictions and guidelines

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

·     In interface range view, only the commands supported by the first interface are available. The first interface is specified with the interface range command.

·     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.

·     No limit is set on the maximum number of interfaces in an interface range. The more interfaces in an interface range, the longer the command execution time.

·     The maximum number of interface range names is limited only by the system resources. 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 member interfaces in the interface range.

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

-     If the execution failed on non-first member interfaces, the command takes effect on the other 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.
