QoS priorities-to-traffic assignment
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 Table 333.
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.
Brocade(config)#interface ethernet 1/1
Brocade(config-if-e1000-1/1)#priority 7
The device assigns priority 7 to untagged switched traffic received on port 1/1.
Use the following command to assign priority levels.
[no] priority <num>
Syntax:
The <num> variable can be from 0 through 7 and specifies the IEEE 802.1 equivalent to one of the
eight QoS queues listed in Table 333.
Assigning static MAC entries to priority queues
By default, all MAC entries are in the best-effort queue. When you configure a static MAC entry, you
can assign the entry to a higher QoS level.
To configure a static MAC entry and assign the entry to the premium queue, enter commands such
as the following.
Brocade(config)#vlan 9
Brocade(config-vlan-9)#static-mac-address 1145.1163.67FF ethernet 1/1 priority 7
Brocade(config-vlan-9)#write memory
Use the following command to configure a MAC entry and assign the entry to a priority queue.
