Forwarding-Class To Queue-ID Map
There are 8 forwarding classes supported on 7210 SAS M. Each of these FC is mapped to a
specific queue while traffic is flowing on the egress port. By mapping FC to different queues the
differential treatment is imparted to various classes of traffic.
In the7210 SAS M, there are only 8 queues available at the port level. These 8 queues are created
by default per port. Users cannot create or delete the queues or the queue ID. Only the queue
parameters can be changed. The queue-id is not a configurable entity and queue ID 1 to 8 are, by
default, used to identify these 8 queues available on the port. The 8 queues are available both on
the access and network ports. Queue parameters for these 8 queues can be configured as part of the
access egress QoS policy which is applied on the access ports and network queue policy which is
applied on the network ports.
The queue ID 1 to 8 are assigned to each of the 8 queues. Queue-ID 8 is the highest priority and
queue-id 1is the lowest priority. FCs are correspondingly mapped to these queue IDs according to
their priority. The stystem defined map is as shown in
FC-QiD
