# Monitoring the QoS Configuration of IP Interfaces

#### Purpose

Display the QoS configuration on a particular IP interface.

A dynamic IP interface can have a QoS profile attached by RADIUS. For example, if configured by RADIUS, the show ip interface command might show the following:

      Attached QoS profile: Strict-qos

However, if the profile is configured statically, the QoS profile is attached to the ATM subinterface, and the attachment is displayed by the show atm subinterface command rather than show ip interface.

#### Action

To display the QoS configuration for an IP interface:

    host1#show ip interface atm 2/0.1
    ATM2/0.1 line protocol Atm1483 is up, ip is up

    ..........................................

      Attached QoS profile: test @ ATM2/0

      queue 0: traffic class best-effort, bound to ip ATM2/0.1
        Queue length 0 Bytes
        Forwarded packets 0, Bytes 0
        Dropped committed packets 0, Bytes 0
        Dropped conformed packets 0, Bytes 0
        Dropped exceeded packets 0, Bytes 0
        Dropped by WRED committed packets 0, bytes 0
        Dropped by WRED conformed packets 0, bytes 0
        Dropped by WRED exceeded packets 0, bytes 0
        Average queue length 150576 bytes
      queue 1: traffic class tc1, bound to ip ATM2/0.1
        Queue length 0 Bytes
        Forwarded packets 0, Bytes 0
        Dropped committed packets 0, Bytes 0
        Dropped conformed packets 0, Bytes 0
        Dropped exceeded packets 0, Bytes 0
        Dropped by WRED committed packets 0, bytes 0
        Dropped by WRED conformed packets 0, bytes 0
        Dropped by WRED exceeded packets 0, bytes 0
        Average queue length 150576 bytes

#### Meaning

Table 50 lists the related show ip interface command output fields.

Table 50: show ip interface Output Fields

Field Name | Field Description
--- | ---
Attached QoS profile | QoS profile attachment at or below the displayed interface. For example, if the interface being displayed is an IP interface, and the attachment is at the VC, the VC interface attachment is displayed.
queue 0 | Number of the queue for which statistics are being displayed and whether the queue is under traffic class control
traffic class | Name of traffic class
bound to | Interface to which queue is bound
Queue length | Size of queue in length and bytes
Forwarded | Number of forwarded packets and bytes
Dropped committed | Number of committed packets and bytes dropped
Dropped conformed | Number of conformed packets and bytes dropped
Dropped exceeded | Number of exceeded packets and bytes dropped
Dropped by WRED committed | Number of committed packets and bytes dropped by WRED
Dropped by WRED conformed | Number of conformed packets and bytes dropped by WRED
Dropped by WRED exceeded | Number of exceeded packets and bytes dropped by WRED
Average queue length | Average length of queue in bytes
