Displaying And Maintaining Service Loopback Groups; Service Loopback Group Configuration Example - HP 3600 v2 series Configuration Manual

You can change the service type of an existing service loopback group. For the change to be successful,
•
make sure that the service group has not been referenced, the attributes of all member ports (if any) do
not conflict 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 other features reference.

Service loopback group configuration example

Network requirements
All the Ethernet ports of Device A support the tunnel service. Assign Ethernet1/0/1 through
Ethernet1/0/3 to a service loopback group to increase bandwidth and achieve load sharing for tunnel
traffic.
Configuration procedure
# Create service loopback group 1, and specify the service type as tunnel (unicast tunnel service).
<DeviceA> system-view
[DeviceA] service-loopback group 1 type tunnel
# Disable MSTP, LLDP, and NDP on Ethernet1/0/1 through Ethernet1/0/3 and then assign them to
service loopback group 1.
[DeviceA] interface ethernet 1/0/1
[DeviceA-Ethernet1/0/1] undo stp enable
[DeviceA-Ethernet1/0/1] undo lldp enable
[DeviceA-Ethernet1/0/1] undo ndp enable
[DeviceA-Ethernet1/0/1] port service-loopback group 1
[DeviceA-Ethernet1/0/1] quit
[DeviceA] interface ethernet 1/0/2
[DeviceA-Ethernet1/0/2] undo stp enable
[DeviceA-Ethernet1/0/2] undo lldp enable
[DeviceA-Ethernet1/0/2] undo ndp enable
[DeviceA-Ethernet1/0/2] port service-loopback group 1
[DeviceA-Ethernet1/0/2] quit
[DeviceA] interface ethernet 1/0/3
[DeviceA-Ethernet1/0/3] undo stp enable
[DeviceA-Ethernet1/0/3] undo lldp enable
[DeviceA-Ethernet1/0/3] undo ndp enable
[DeviceA-Ethernet1/0/3] port service-loopback group 1
[DeviceA-Ethernet1/0/3] quit
