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

Table 1 lists the related show ip interface command output fields.
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 |
