Restrictions and guidelines: Service loopback group configuration
When you add member ports to a service loopback group, follow these restrictions and guidelines:
· Make sure the ports support the service type of the service loopback group and are not members of any other service loopback group.
When you apply service loopback groups to features, follow these restrictions and guidelines:
· A service loopback group can process services only after it is used by other features. You can apply a service loopback group to other features once the group is created. One service loopback group can be used by multiple features.
· 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.
