Bulk configuring interfaces
About interface bulk configuration
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.
To configure interfaces in bulk, you must configure an interface range and enter its view by using the
interface range
or
interface range name
command.
The interface range created by using the
interface range
command is not saved to the running
configuration. You cannot use the interface range repeatedly. To create an interface range that can
be used repeatedly, use the
interface range
name
command.
Restrictions and guidelines: Bulk interface
configuration
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 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-typeinterface-number
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. This 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. This 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.
