QoS priorities-to-traffic assignment
By default, all traffic is in the best-effort queue (qosp0) and is honored on tagged ports on all FastIron
switches. You can assign traffic to a higher queue based on the following:
• Incoming port (sometimes called the ingress port )
• Static MAC entry
When you change the priority, you specify a number from 0 through 7. The priority number specifies the
IEEE 802.1 equivalent to one of the eight QoS queues on Brocade devices. The numbers correspond to
the queues as shown in the QoS queues table.
Although it is possible for a packet to qualify for an adjusted QoS priority based on more than one of the
criteria, the system always gives a packet the highest priority for which it qualifies. Thus, if a packet is
entitled to the premium queue because of its IP source and destination addresses, but is entitled only to
the high queue because of its incoming port, the system places the packet in the premium queue on the
outgoing port.
Changing a port priority
To change the QoS priority of port 1/1 to the premium queue (qosp7), enter the following commands.
device(config)# interface ethernet 1/1
device(config-if-e1000-1/1)#priority 7
