interface range

Function

The interface range command creates a temporary interface group and adds specified interfaces to this temporary interface group. Commands configured for a temporary interface group then automatically run on all member interfaces.

By default, no temporary interface group is created.

Format

interface range { interface-type interface-number1 [ to interface-type interface-number2 ] } &<1-10>

Parameters

Parameter	Description	Value
interface-type interface-number1 [ to interface-type interface-number2 ]	Specifies Ethernet interfaces to be added to a temporary port group. to indicates an interface range. All interfaces numbered between interface-number1 and interface-number2 are added to the temporary port group.	The value of interface-number2 must be larger than the value of interface-number1.

Usage Guidelines

Usage Scenario

When the same configuration needs to be performed on multiple Ethernet interfaces, one-by-one configuration on each interface may result in errors and a large amount of duplicated workload.

The port group function can solve this problem. You can add the Ethernet interfaces to the same port group. After you run the configuration command once in the port group view, the configuration takes effect on all Ethernet interfaces in the port group, reducing your workload.

Precautions

The interface range and port-group group-member commands have the same functions. Therefore, use either of the commands for configuration. After exiting from the temporary port group view, the system deletes the temporary port group.
The interface range command is equivalent to the group-member command executed in the permanent port group view. Multiple interfaces can be added to a permanent port group in batches using the group-member command.
When you specify the keyword to in the interface range command:
- The interfaces specified by interface-number1 and interface-number2 must reside on the same LPU. To add contiguous interfaces on different LPUs to the same port group, run this command several times or use the keyword to several times.
- The interfaces specified by interface-number1 and interface-number2 must be of the same type, for example, both of the interfaces are Ethernet interfaces.
- The interfaces specified before and after the keyword to must have the same attribute. For example, both of them are main interfaces or sub-interfaces. If they are sub-interfaces, they must belong to the same main interface.
- If to is not specified, the preceding limitations do not apply.
