Service loopback group commands
display service-loopback group
Use display service-loopback group to display service loopback group information.
Syntax
display service-loopback group [ group-id ]
Views
Any view
Predefined user roles
network-admin
network-operator
Parameters
group-id: Specifies a service loopback group ID. The value range for the group-id argument is 1 to 1024. If you do not specify a service loopback group, this command displays information about all service loopback groups.
Examples
# Display information about service loopback group 5.
<Sysname> display service-loopback group 5
Service Group ID: 5 Service Type: Tunnel
Member:
GigabitEthernet1/0/1
GigabitEthernet1/0/2
Table 1 Command output
|
Field |
Description |
|
Service Group ID |
Service loopback group ID. |
|
Service Type |
Service type of the service loopback group. The Tunnel service supports unicast tunnel traffic. |
|
Member |
Member ports of the service loopback group. |
port service-loopback group
Use port service-loopback group to assign a port to a service loopback group.
Use undo port service-loopback group to remove a port from a service loopback group.
Syntax
port service-loopback group group-id
undo port service-loopback group
Default
A port does not belong to any service loopback group.
Views
Layer 2 Ethernet interface view
Predefined user roles
network-admin
Parameters
group-id: Specifies a service loopback group ID. The value range for the group-id argument is 1 to 1024.
Usage guidelines
When you assign a port to a service loopback group, the system removes the configuration on the port. Make sure you are fully aware of the impact of this command before using it on a live network.
To avoid IRF split, do not assign a physical interface to a service loopback group if that interface is the only member interface of an IRF port.
Before assigning a port to a service loopback group, make sure the port supports the service type of the group.
A port can belong to only one service loopback group. You can assign multiple ports 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.
Examples
# Assign GigabitEthernet 1/0/1 to service loopback group 5.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] port service-loopback group 5
service-loopback group
Use service-loopback group to create a service loopback group and specify its service type.
Use undo service-loopback group to delete a service loopback group.
Syntax
service-loopback group group-id type tunnel
undo service-loopback group group-id
Default
No service loopback groups exist.

Parameters
group-id: Specifies a service loopback group ID. The value range for the group-id argument is 1 to 1024.
type: Specifies the service type of the service loopback group.
tunnel: Specifies the unicast tunnel service.
Usage guidelines
Service loopback groups must work with other features, such as GRE. A service loopback group can be used by multiple features.
You must create a service loopback group before you can use it with a feature.
You cannot change the service type of a service loopback group.
To ensure correct traffic processing, do not delete a service loopback group that is being used by a feature.
Examples
# Create service loopback group 5 and specify the unicast tunnel service for the group.
<Sysname> system-view
[Sysname] service-loopback group 5 type tunnel
