Queue Cos-Map - SMC Networks SMC TigerStack III SMC6824M Management Manual

the incoming frame is an IEEE 802.1Q VLAN tagged frame, the IEEE
802.1p User Priority bits will be used.
• This switch provides four priority queues for each port. It is configured
to use Weighted Round Robin, which can be viewed with the show
queue bandwidth command. Inbound frames that do not have VLAN
tags are tagged with the input port's default ingress user priority, and
then placed in the appropriate priority queue at the output port. The
default priority for all ingress ports is zero. Therefore, any inbound
frames that do not have priority tags will be placed in queue 0 of the
output port. (Note that if the output port is an untagged member of the
associated VLAN, these frames are stripped of all VLAN tags prior to
transmission.)
Example
The following example shows how to set a default priority on port 3 to 5:
Console(config)#interface ethernet 1/3
Console (config-if)#switchport priority default 5

queue cos-map

This command assigns class of service (CoS) values to the priority queues
(i.e., hardware output queues 0 - 3). Use the no form to set the CoS map to
the default values.
Syntax
queue cos-map queue_id [cos1 ... cosn]
no queue cos-map
• queue_id - The ID of the priority queue.
• Ranges are 0 to 3, where 3 is the highest priority queue.
• cos1 .. cosn - The CoS values that are mapped to the queue ID. It is a
space-separated list of numbers. The CoS value is a number from 0 to
7, where 7 is the highest priority.
