    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

    Table 1: 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

    Displays a cumulative number of committed, conformed, and exceeded packets dropped by WRED for ES2 10G ADV LMs.

    Dropped by WRED conformed

    Number of conformed packets and bytes dropped by WRED

    Displays a value of zero for ES2 10G ADV LMs because of the single counter used to calculate packets dropped by WRED functionality (as an aggregate of all colors) for these LMs.

    Dropped by WRED exceeded

    Number of exceeded packets and bytes dropped by WRED

    Displays a value of zero for ES2 10G ADV LMs because of the single counter used to calculate packets dropped by WRED functionality (as an aggregate of all colors) for these LMs.

    Average queue length

    Average length of queue in bytes
