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.
•
If you cannot enter the view of an interface by using the
interface interface-type
interface-number
command, do not configure the interface as the first interface in the interface
range.
•
Do not assign both an aggregate interface and any of its member interfaces to an interface
range. Some commands might break up the aggregation after they are executed on both an
aggregate interface and its member interfaces.
•
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 stays in interface range view and does not display an error message. It means
that the execution succeeded on all member interfaces in the interface range.
{
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.
