This dialog box provides information about logical interfaces/media types and the service policy maps attached to them.

The following information appears:

> Logical Interface/Media Type (cbQosIfType)

> Policy Direction (cbQosPolicyDirection)

> Interface Index (cbQosIfIndex)

> Frame Relay DLCI (cbQosFrDLCI)

> ATM VPI (cbQosAtmVPI)

> ATM VCI (cbQosAtmVCI)

> Entity Index (cbQosEntityIndex)

> Vlan Index (cbQosVlanIndex)

### Logical Interface/Media Type (cbQosIfType)

Logical interface/media type to which this service policy is attached.

There are six possible values:

| mainInterface(1) | atmPVC(4)
| subInterface(2) | controlPlane(5)
| frDLCI(3) | vlanPort(6)

### Policy Direction (cbQosPolicyDirection)

Direction of traffic in which this service policy is applied.

There are two possible values:

> input(1)

> output(2)

### Interface Index (cbQosIfIndex)

ifIndex value of the interface to which this service policy is attached. This field is applicable only if the logical interface has a SNMP ifIndex value.

### Frame Relay DLCI (cbQosFrDLCI)

Data-link connection identifier (DLCI) for the Frame Relay virtual circuit (VC) to which this service is attached. This field is applicable only if the service policy is attached to a Frame Relay DLCI.

### ATM VPI (cbQosAtmVPI)

Virtual path identifier (VPI) for the ATM VC to which this service is attached. This field is applicable only if the service policy is attached to an ATM VC.

### ATM VCI (cbQosAtmVCI)

Virtual channel identifier (VCI) for the ATM VC to which this service is attached. This field is applicable only if the service policy is attached to an ATM VC.

### Entity Index (cbQosEntityIndex)

When the service policy is attached to an entity (for example, a control-plane), this object indicates the physical index of the entity to which the policy has been attached. The value zero may be returned if the policy is not attached to a physical entity or entPhysicalTable is not supported by the SNMP agent.

### Vlan Index (cbQosVlanIndex)

If the service policy is attached to a particular VLAN on a Trunk or multi-VLAN access port, then this object specifies the corresponding VLAN. Otherwise, the value of this object is zero.
