Service-Loopback Group - H3C S7500E Series Command Reference Manual

A service loopback group can be referenced by multiple features at the same time, for example, by
multiple tunnel interfaces. It is recommended that you assign more ports to a service loopback group
that is likely to be referenced by multiple features at the same time, so that the service loopback group
can provide sufficient bandwidth.
Examples
# Assign interface GigabitEthernet 2/0/1 to service loopback group 5.
<Sysname> system-view
[Sysname] interface gigabitEthernet 2/0/1
[Sysname-GigabitEthernet2/0/1] port service-loopback group 5

Parameters
number: Service loopback group ID. The value range for the number argument is 1 to 1024.
type: Specifies the service type of a service loopback group. Support for this keyword varies with
device models.
tunnel: Specifies the service type of a service loopback group as Tunnel (unicast tunnel service).
multicast-tunnel: Specifies the service type of a service loopback group as Multicast tunnel.
Description
Use the service-loopback group command to create a service loopback group and specify its service
type.
Use the undo service-loopback group command to remove a service loopback group.
Note that:
A service loopback group can be referenced by other features after its creation. Only after being
referenced can a service loopback group process service traffic. A service loopback group can 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, you must ensure that the service group has not been referenced; the attributes of all
member ports (if any) are not conflicting with the target service type; and no service loopback
group has been created for the target service type, because only one service loopback group is
allowed for a service type.
