queue
Syntax queue queue-id [strict |weight weight]
no queue queue-id
Context config>qos>port-sched-plcy
Description
This command configures a port scheduler queue. The queue and its weights can be configured
only for WRR/WDRR modes. The weight specified in case of WRR corresponds to the number of
packets that needs to be sent out in a cycle for that particular queue.
For WDRR, the weight specified is the ratio of traffic that will be sent out for that particular queue.
For example, in WDRR, if a weight value for queue 1 is 1 and a weight value for queue 2 is 5, then
traffic out of the port is in the ratio of 1:5 between the queues (1 and 2) provided no traffic is
flowing in the other queues. If the keyword strict is specified in any of the queues, then that
particular queue will be treated as strict. This set of strict priority queues is serviced first in the
order of their CoS numbering (the higher numbered CoS queue receives service before smaller
numbered queues).
The no form of the queue under a WRR/WDRR mode will set the queue weights to default (for
example, 1).
Parameters queue-id — Specifies the queue ID.
Values 1 — 8 (8 is the highest)
strict — Specifies strict access.
weight weight — Specifies the number of packets in case of WRR and ratio of traffic out in WDRR.
Values 1 — 5 (For 7210 SAS-E)
Values 1—15 (For 7210 SAS-D)
