You can guarantee the
availability of buffers, set WTD thresholds, and configure the maximum
allocation for a queue-set by using the
mls qos queue-set
output
qset-id
threshold
queue-id
drop-threshold1
drop-threshold2 reserved-threshold maximum-threshold
global configuration command.
Each threshold value is a
percentage of the queue’s allocated buffers, which you specify by using the
mls qos queue-set
output
qset-id
buffers
allocation1 ...
allocation4 global configuration command. The queues use WTD to
support distinct drop percentages for different traffic classes.
Note |
The egress queue default
settings are suitable for most situations. You should change them only when you
have a thorough understanding of the egress queues and if these settings do not
meet your QoS solution.

Beginning in privileged EXEC
mode, follow these steps to configure the memory allocation and to drop
thresholds for a queue-set. This procedure is optional.
