type: Specifies the service type of a service loopback group.
tunnel: Specifies the service type of a service loopback group as Tunnel (unicast tunnel service).
Description
Use service-loopback group to create a service loopback group and specify its service type.
Use undo service-loopback group to remove a service loopback group.
A service loopback group can be referenced by other features once it is created, and can process service
traffic only after it is referenced. A service loopback group may be referenced by multiple features at the
same time.
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 (if any) are not conflicting with the target service type
•
No service loopback group has been created for the target service type. 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
