Configuring Service Loopback Groups; Configuration Procedure - HP 6125XLG Configuration Manual

Configuring service loopback groups

A service loopback group contains one or multiple Ethernet ports for looping packets sent out by the
device back to the device. This feature must work with other features, such as GRE.
A service loopback group provides one of the following services:
Tunnel—Supports unicast tunnel traffic.
•
• Multicast tunnel—Supports multicast tunnel traffic.
Multiport—Supports multiport ARP traffic. This service is available in Release 2406P03 and later
•
versions.
You can configure only one service loopback group for a service type. You can use a service loopback
group with multiple features.
Member ports in a service loopback group are load balanced.

Configuration procedure

Follow these guidelines when you configure a service loopback group:
Make sure the ports you are assigning to a service loopback group meet the following
•
requirements:
The ports are not used for any other purposes. The configuration on a port is removed when it
is assigned to a service loopback group.
The ports support the service type of the service loopback group and are not members of any
other service loopback group.
You cannot change the service type of a service loopback group.
•
For correct traffic processing, follow these guidelines:
•
Make sure a service loopback group has a minimum of one member port when it is being used
by a feature.
Do not delete a service loopback group when it is being used by a feature.
To configure a service loopback group:
Step
1. Enter system view.
2. Create a service loopback
group and specify its service
type.
3. Enter Layer 2 Ethernet
interface view.
4. Assign the port to the service
loopback group.
