Quality of Service (QoS) Commands
11-39
202-10088-01, March 2005
Sent Octets/Packets
A count of the octets/packets forwarded for this class instance
after the defined DiffServ treatment was applied. In this case, for-
warding means the traffic stream was passed to the next func-
tional element in the data path, such as the switching or routing
function or an outbound link transmission element. Only dis-
played for the 'out' direction.
Note:
None of the counters listed here are guaranteed to be supported on all
platforms. Only supported counters are shown in the display output.
show service-policy
This command displays a summary of policy-oriented statistics information for all interfaces in the
specified direction. The direction parameter indicates the interface direction of interest.
This command enables or disables the route reflector client. A route reflector client relies on a
route reflector to re-advertise its routes to the entire AS. The possible values for this field are
enable
and
disable.
Format
show service-policy <in | out>
Mode
Privileged EXEC
The following information is repeated for each interface and direction (only
those interfaces configured with an attached policy are shown):
Interface
Valid slot and port number separated by forward slashes.
Dir
The traffic direction of this interface service, either in or out.
Operational Status
The current operational status of this DiffServ service interface.
Offered Packets
A count of the total number of packets offered to all class
instances in this service before their defined DiffServ treatment is
applied. These are overall per-interface per-direction counts.
Discarded Packets
A count of the total number of packets discarded for all class
instances in this service for any reason due to DiffServ treatment.
These are overall per-interface per-direction counts.
Sent Packets
A count of the total number of packets forwarded for all class
instances in this service after their defined DiffServ treatments
were applied. In this case, forwarding means the traffic stream
was passed to the next functional element in the data path, such as
the switching or routing function or an outbound link transmis-
sion element. These are overall per-interface per-direction counts.

Policy Name
The name of the policy attached to the interface.
Note:
None of the counters listed here are guaranteed to be supported
on all platforms. Only supported counters are shown in the dis-
play output.
Class of Service (CoS) Commands
This chapter provides a detailed explanation of the software QoS CoS commands. The following
commands are available in the software QOS module.
The commands are divided into these different groups:
•
Configuration Commands are used to configure features and options of the switch. For every
configuration command there is a show command that will display the configuration setting.
•
Show commands are used to display device settings, statistics and other information.
Note:
The 'Interface Config' mode only affects a single interface, whereas the 'Global Config'
mode is applied to all interfaces.
classofservice dot1p-mapping
This command maps an 802.1p priority to an internal traffic class.
The userpriority and
trafficclass can both range from 0-7, although the actual number of available traffic classes
depends on the platform.
The 'no' form of this command is not supported.
Format
classofservice dot1p-mapping <userpriority> <traffic-
class>
Modes
Global Config
Interface Config
classofservice ip-dscp-mapping
This command maps an IP DSCP value to an internal traffic class. The ipdscp range is from 0-63
and the trafficclass range is from 0-7, although the actual number of available traffic classes
depends on the platform.
The 'no' form of this command is not supported.
Format
classofservice ip-dscp-mapping <ipdscp> <traffic-
class>

classofservice ip-precedence-mapping
This command maps an IP precedence value to an internal traffic class.
The ipprecedence and
trafficclass can both range from 0-7, although the actual number of available traffic classes
depends on the platform.
The 'no' form of this command is not supported.
Format
classofservice ip-precedence-mapping <ipprecedence>
<trafficclass>
Modes
Global Config
Interface Config
classofservice trust
This command sets the class of service trust mode of an interface.
The mode can be set to trust one
of the Dot1p (802.1p), IP Precedence, or IP DSCP packet markings.
Format
classofservice trust <dot1p/ip-precedence/ip-dscp>
Mode
Global Config
Interface Config
no classofservice trust
This command sets the interface mode to untrusted.
Format
no classofservice trust
Modes
Global Config
Interface Config
cos-queue max-bandwidth
This command specifies the maximum transmission bandwidth limit for each interface queue.
Also known as rate shaping, this has the effect of smoothing temporary traffic bursts over time so
that the transmitted traffic rate is bounded.
The total number of queues supported per interface is
platform specific.
Format
cos-queue max-bandwidth <bw-0> <bw-1> … <bw-n>
Modes

no cos-queue max-bandwidth
This command restores the default for each queue's maximum bandwidth value.
Format
no cos-queue max-bandwidth
Mode
Global Config
Interface Config
cos-queue min-bandwidth
This command specifies the minimum transmission bandwidth guarantee for each interface queue.
The total number of queues supported per interface is platform specific.
Format
cos-queue min-bandwidth <bw-0> <bw-1> … <bw-n>
Modes
Global Config
Interface Config
no cos-queue min-bandwidth
This command restores the default for each queue's minimum bandwidth value.
Format
no cos-queue min-bandwidth
Modes
Global Config
Interface Config
cos-queue random-detect
This command activates weighted random early discard (WRED) for each specified queue on the
interface.
Specific WRED parameters are configured using the 'random-detect queue-parms' and
the 'random-detect exponential-weighting-constant' commands.
Format
cos-queue random-detect <queue-id-1> [<queue-id-2> …
<queue-id-n>]
Modes
Global Config
Interface Config
no cos-queue random-detect
This command disables WRED, thereby restoring the default tail drop operation for the specified
queues on the interface.
Format
no cos-queue random-detect <queue-id-1> [<queue-id-2>
… <queue-id-n>]

random-detect
This command is used to enable WRED for the interface as a whole, and is only available when
per-queue WRED activation control is not supported by the device.

weighting-constant' commands.
