HP 5820X Series User Manual

A service loopback group can be referenced by multiple features at the same time, for example, by
multiple tunnel interfaces. 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.
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.
You cannot remove a service loopback group that is referenced by other features.

Service loopback group configuration example
Network requirements
Ports of Switch A support the tunnel service. Assign GigabitEthernet 1/0/1 through GigabitEthernet
1/0/3 to a service loopback group to increase bandwidth and achieve load sharing.
Configuration procedure
# Create service loopback group 1, and specify the service type as Tunnel (unicast tunnel service).

[SwitchA] service-loopback group 1 type tunnel
# Disable MSTP, NDP and LLDP on GigabitEthernet 1/0/1 through GigabitEthernet 1/0/3 and then
assign them to service loopback group 1.
