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.
•
You cannot enter the view of some interfaces by using the
interface
interface-type
{
interface-number
|
interface-number.subnumber
} command, for example, BRI 1/1/1:1. Do not
configure any of these interfaces 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, 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, H3C recommends that you 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 fails on member interfaces in the interface range.
−
If the execution fails on the first member interface in the interface range, the command is not
executed on any member interfaces.
−
If the execution fails 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 fails on a member interface in interface range view and succeeds 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 unnecessary, use the
undo
form of the command to remove the configuration.
