Class of Service (CoS) Commands 231
5 Quality of Service (QoS) Commands
IP DSCP The IP DSCP value.
Traffic Class The traffic class internal queue identifier to which the IP DSCP value is
mapped.
show classofservice trust
This command displays the current trust mode setting for a specific interface. The <slot/
port>
parameter is optional and is only valid on platforms that support independent per-port
class of service mappings. If you specify an interface, the command displays the port trust
mode of the interface. If you do not specify an interface, the command displays the most
recent global configuration settings.
Format
show classofservice trust [<slot/port>]
Mode Privileged EXEC
Non-IP Traffic Class The traffic class used for non-IP traffic. This is only displayed when
the COS trust mode is set to trust IP Precedence or IP DSCP (on platforms
that support IP DSCP).
Untrusted Traffic Class The traffic class used for all untrusted traffic. This is only displayed
when the COS trust mode is set to 'untrusted'.
show interfaces cos-queue
This command displays the class-of-service queue configuration for the specified interface.
The slot/port parameter is optional and is only valid on platforms that support independent per-
port class of service mappings. If specified, the class-of-service queue configuration of the
interface is displayed. If omitted, the most recent global configuration settings are displayed.
Format
show interfaces cos-queue [<slot/port>]
Mode Privileged EXEC
Queue Id An interface supports n queues numbered 0 to (n-1). The specific n value is
platform dependent.
Minimum Bandwidth The minimum transmission bandwidth guarantee for the queue,
expressed as a percentage. A value of 0 means bandwidth is not guaranteed
and the queue operates using best-effort. This is a configured value.
Scheduler Type Indicates whether this queue is scheduled for transmission using a strict pri-
ority or a weighted scheme. This is a configured value.
Queue Management Type The queue depth management technique used for this queue (tail
drop).
If you specify the interface, the command also displays the following information.
Interface The slot/port of the interface. If displaying the global configuration, this out-
put line is replaced with a Global Config indication.
Interface Shaping Rate The maximum transmission bandwidth limit for the interface as a
whole. It is independent of any per-queue maximum bandwidth value(s) in
effect for the interface. This is a configured value.
