Default command level

2: System level

Parameters

number: Specifies a service loopback group ID, in the range of 1 to 1024.

Usage guidelines

Repeat this command to assign multiple ports to a service loopback group.

You cannot remove the last member port of a referenced service loopback group.

Examples

# Assign interface GigabitEthernet 1/0/1 to service loopback group 5.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] port service-loopback group 5

service-loopback group

Use service-loopback group to create a service loopback group and specify its service type.

undo service-loopback group number

Views

System view

Default command level

2: System level

Parameters

number: Specifies a service loopback group ID, in the range of 1 to 1024.

type: Specifies the service type of the service loopback group.

multicast-tunnel: Specifies the multicast tunnel service.

tunnel: Specifies the unicast tunnel service.

Usage guidelines

Service loopback groups must work with other features, such as GRE. A service loopback group can be used by multiple features.

You can change the service type of an existing service loopback group. For the change to be successful, verify the following conditions:

·           The service group has not been referenced.

·           The attributes of all member ports are not conflicting with the target service type.

·           No service loopback group has been created for the target service type, because only one service loopback group is allowed for a service type.

You cannot remove a service loopback group that is referenced by other features.

Examples

# Configure service loopback group 5 and specify its service type as Tunnel.

<Sysname> system-view

[Sysname] service-loopback group 5 type tunnel
