QoS Commands 657
User Guidelines
The maximum number of queues supported per interface is seven. When
ETS is operational on a switch, this command overrides the ETS assignments
and assigns minimum bandwidth constraints across traffic class groups. This
allows the administrator to ensure that the frame scheduler does not
completely starve lower priority groups when strict priority is enabled on a
high numbered TCG. Specifically, assigning a minimum bandwidth to a
lower numbered TCG, even when strict priority is enabled on a higher
numbered TCG, will alter the normal scheduler behavior and cause the
scheduler to process frames from the lower numbered TCG to conform to the
min-bandwidth constraint.
Example
The following example displays how to specify the minimum transmission
bandwidth for seven interfaces.
console(config)#cos-queue min-bandwidth 0 0 5 5 10 10
10
cos-queue random-detect
Use the cos-queue random-detect command in Global Configuration or
Interface Configuration mode to configure WRED queue management
policy on an interface CoS queue. Use the no form of the command to
disable WRED policy for a CoS queue on an interface.
Syntax
cos-queue {random-detect queue-id1 [ queue-id2 .. queue-idn ]}
no cos-queue {random-detect
queue-id1 [ queue-id2 .. queue-idn ]}
Parameter Description
Parameter Description
queue-id An integer indicating the queue-id which is to be enabled for
WRED. Range 0-6. Up to 7 queues may be simultaneously
specified.
