Table 19: Forwarding Class To Queue-Id Map - Alcatel-Lucent 7210 SAS E OS Quality Of Service Manual

QoS Overview
Forwarding-Class To Queue-ID Map
There are 8 forwarding classes supported on 7210 SAS E. 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 the 7210 SAS E 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 access uplink 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 access uplink 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 map is as shown in
FC-QiD
