Parameters
number: Specifies a service loopback group ID. The value range for the number argument is 1 to
1024.
Usage guidelines
Before assigning a port to a service loopback group, make sure the port supports the service type of
the group.
You can assign a maximum of 8 ports to a service loopback group.
When you assign a port to a service loopback group, the system removes the configuration on the
port. 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.
