shutdown interface

Function

The shutdown interface command shuts down sub-interfaces in a batch.

The undo shutdown interface command starts sub-interfaces in a batch.

By default, a sub-interface is started.

Format

shutdown interface { ifname | beginIfType beginIfNum } to { endIfname | endIfType endIfNum }

undo shutdown interface { ifname | beginIfType beginIfNum } to { endIfname | endIfType endIfNum }

Parameters

Parameter	Description	Value
ifname	Specifies a start interface name.	-
beginIfType	Specifies a start interface type.	The interfaces must support sub-interfaces.
beginIfNum	Specifies a start interface number.	-
to	The keyword to is used to connect two interfaces, indicating that the interface numbers are all interfaces between two interfaces (including these two interfaces).	-
endIfname	Specifies an end interface name.	-
endIfType	Specifies an end interface type.	The interfaces must support sub-interfaces.
endIfNum	Specifies an end interface number.	-

Usage Guidelines

Usage Scenario

If a main interface has a large number of sub-interfaces, to disable these interfaces, run the shutdown command on each sub-interface view. To release workloads, run the shutdown interface command to disable sub-interfaces in a batch. After the shutdown interface command is run, the sub-interface operating state changes to Down. If the sub-interface is in the disabled state, run the undo shutdown interface command to start sub-interfaces in a batch, after the undo shutdown interface command is run, the sub-interface operating state is synchronized with the link status.

Prerequisites

The sub-interfaces to be disabled or started in a batch must exist.

Configuration Impact

Running the shutdown interface command will interrupt services on the sub-interfaces. Therefore, exercise caution when running this command.

If the shutdown interface command is run more than once, the latest configuration overrides the previous one.

Precautions

In VS mode, this command is supported only by the admin VS.

When you specify the interface range, note that:

The end interface number must be greater than the start interface number.
The types of the interfaces to which the end interface number and start interface number correspond must be the same
The interfaces in the range must exist.

Example

# Disable sub-interfaces GE0/1/1.1, GE0/1/1.2, and GE0/1/1.3 in a batch.

<HUAWEI> system-view
[~HUAWEI] interface GigabitEthernet 0/1/1.1
[*HUAWEI-GigabitEthernet0/1/1.1] quit
[*HUAWEI] interface GigabitEthernet 0/1/1.2
[*HUAWEI-GigabitEthernet0/1/1.2] quit
[*HUAWEI] interface GigabitEthernet 0/1/1.3
[*HUAWEI-GigabitEthernet0/1/1.3] quit
[*HUAWEI] shutdown interface GigabitEthernet 0/1/1.1 to GigabitEthernet 0/1/1.3
