Configuring a service loopback group
A service loopback group provides only the multiport service that supports multiport ARP traffic.
You can configure only one service loopback group for a service type. However, you can use one 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.
· Do not delete a service loopback group that is being used by a feature.
· An IRF physical interface cannot be assigned to a service loopback group.
· For correct traffic processing, make sure a service loopback group has a minimum of one member port when it is being used by a feature.
To configure a service loopback group:
|
Step |
Command |
Remarks |
|
1. Enter system view. |
system-view |
N/A |
|
2. Create a service loopback group and specify its service type. |
service-loopback group group-id type multiport |
By default, no service loopback group exists. |
|
3. Enter Layer 2 Ethernet interface view. |
interface interface-type interface-number |
N/A |
|
4. Assign the port to the service loopback group. |
port service-loopback group group-id |
By default, a port does not belong to any service loopback group. You can assign a maximum of 32 ports to a service loopback group. |

Network requirements
Assign GigabitEthernet 1/0/1 through GigabitEthernet 1/0/3 to a service loopback group to loop multiport ARP packets sent out by the device back to the device.
Configuration procedure
# Create service loopback group 1, and specify its service type as multiport.
<DeviceA> system-view
[DeviceA] service-loopback group 1 type multiport
# Assign GigabitEthernet 1/0/1 through GigabitEthernet 1/0/3 to service loopback group 1.
[DeviceA] interface gigabitethernet 1/0/1
[DeviceA-GigabitEthernet1/0/1] port service-loopback group 1
All configurations on the interface will be lost. Continue?[Y/N]:y [DeviceA-GigabitEthernet1/0/1] quit
[DeviceA] interface gigabitethernet 1/0/2
[DeviceA-GigabitEthernet1/0/2] port service-loopback group 1
All configurations on the interface will be lost. Continue?[Y/N]:y [DeviceA-GigabitEthernet1/0/2] quit
[DeviceA] interface gigabitethernet 1/0/3
[DeviceA-GigabitEthernet1/0/3] port service-loopback group 1
All configurations on the interface will be lost. Continue?[Y/N]:y [DeviceA-GigabitEthernet1/0/3] quit
