# Configuring Interface Supersets for QoS

Tasks to configure an interface superset for QoS include:

- Configuring an Interface Superset
- Restricting an Interface Superset to an S-VLAN ID or an ATM VP

## Configuring an Interface Superset

To configure an interface superset that contains interface sets and logical interfaces:

1. Create the interface superset.
   `
   host1(config)#qos-interface-super-set vlan-superset-shaping
   `
2. Specify the parent interface for the superset.
   `
   host1(config-interface-superset)#qos-interface-parent interface tenGigabitEthernet 4/0/0
   `

   You can configure an Ethernet major interface, an ATM major interface, or a LAG for the parent interface. You must define the parent before you add interface sets or subinterfaces to the interface superset.

## Restricting an Interface Superset to an S-VLAN ID or an ATM VP

When you configure interface supersets for VLANs or ATM VCs, the member interfaces normally span different S-VLAN IDs or ATM VPs.

Optionally, you can restrict all interface members of a VLAN superset to a specific S-VLAN ID, or all members of an ATM VC to a specific ATM VP.

To restrict the interface members of an interface superset:

1. Specify the interface superset.
   `
   host1(config)qos-interface-superset residential-customers
   `
2. Restrict the interfaces in the interface superset.

   For VLAN supersets, restrict the VLAN subinterfaces to an S-VLAN ID:

   `
   host1(config-qos-interface-superset)#restricted interface tenGigabitEthernet 4/0/0 svlan id 2
   `

   For ATM VC supersets, restrict an ATM VC to an ATM VP:

   `
   host1(config-qos-interface-superset)#restricted interface atm 2/0/0 atm-vp 2
   `
