Adding Interfaces to an Interface Set with RADIUS

You can add interfaces to an interface set using the QoS-Interfaceset-Name RADIUS
VSA attribute [26-130].
This VSA is useful when configuring local loop topologies of interface sets in the
network. When the subscriber interface is created, the VSA supplies the interface
name and the subscriber interface. The system matches the subscriber interface with
the member-interface type that is specified in the interface set. Note that the VSA
cannot specify an interface superset.
When multiple subscribers exist in one interface set, such as PPPoE subscribers over
the same VLAN, they are joined with the first subscriber's VSA. The system generates
an error message if one of the subscribers attempts to join another interface set using
another VSA.
Leaving an interface set is not supported from RADIUS. The interface leaves an
interface set when it is deleted or manually removed from the interface set through
the CLI.

Changing and Deleting Interface Members in an Interface Set

If you want to move interface members in an interface set, we recommend that you
delete the interface member from the interface set before associating it with another
interface.
To move an interface member from an interface set to another interface set:
1.
2.
3.

Changing Interface Members with Upper-Layer Protocols in an Interface Set

When upper-layer protocols such as IP are configured on an interface set, moving
an interface member from one interface set to another interface set can cause
problems with the interface column in munged QoS profiles.
For example, moving an interface set to an upper layer binding causes the interface
set to appear below the subinterface level. If a QoS profile were attached to the VLAN
subinterface in this example, the munged QoS profile for all IP interfaces stacked
above the subinterface would change.
Specify the subinterface associated with the member interface.
host1(config)#interface gigabitEthernet 4/0/0.1
Delete the member interface from the subinterface using the no version of the
command.
host1(sub-if)#no qos-interface-parent vlan-business
Configure the new interface set for the member interface.
host1(sub-if)#qos-interface-parent vlan-residential
