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 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 in an interface range, 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.

Enter system view.

2.
Enter interface range

•
interface range
{

interface-number
[

By using the
interface range
name
command, you assign a name to an
interface range and can specify this
name rather than the interface range
to enter the interface range view.
