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

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

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
