show mls qos interface
Usage Guidelines
If no keyword is specified with the show mls qos interface command, the display shows the port trusted
mode (DSCP trusted, CoS trusted, untrusted, and so forth), the default CoS value, the
DSCP-to-DSCP-mutation map (if any) attached to the port, and the policy map (if any) attached to the
interface. If a specific interface is not specified, the information for all interfaces appears.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output
do not appear, but the lines that contain Output appear.
Examples
This is an example of output from the show mls qos interface command:
Switch# show mls qos interface fastethernet0/1
FastEthernet0/1
trust state: not trusted
trust mode: trust cos
COS override: dis
default COS: 0
DSCP Mutation Map: Default DSCP Mutation Map
trust device: cisco-phone
This is an example of output from the show mls qos interface gigabitethernet0/1 buffers command:
Switch> show mls qos interface gigabitethernet0/1 buffers
GigabitEthernet0/1
Notify Q depth:
qid-size
1 - 25
2 - 25

4 - 25
qid WRED thresh1 thresh2

4
In the preceding display, the qid-size section shows the weight (the amount of space allocated to each
queue) as configured by the wrr-queue queue-limit interface configuration command. The next section
of the display shows the settings of the tail-drop thresholds for all four queues. The WRED column
shows that it is disabled, which means that tail drop is in effect. Tail-drop thresholds are configured by
using the wrr-queue threshold interface configuration command.
This is an example of output from the show mls qos interface fastethernet0/1 buffers command:
Switch> show mls qos interface fastethernet0/1 buffers
FastEthernet0/1
Minimum reserve buffer size:
100 100 100 100 100 100 100 100
Minimum reserve buffer level select:
4 2 5 7
This sample shows that the buffer size for all minimum-reserve levels is set to 100 packets. The last line
of the display shows that queue 1 selects minimum-reserve level 4, queue 2 selects minimum-reserve
level 2, queue 3 selects minimum-reserve level 5, and queue 4 selects minimum-reserve level 7.
This is an example of output from the show mls qos interface gigabitethernet0/1 queueing command:
Switch> show mls qos interface gigabitethernet0/1 queueing
