When you apply a QoS priority to one of the items listed above, you specify a number from 0 – 7.
The priority number specifies the IEEE 802.1p equivalent to one of the four Brocade QoS queues.
The numbers correspond to the queues as follows.
Priority level
6, 7
4, 5
2, 3
0, 1
Changing a port's priority
To change a port's QoS priority, use one of the following methods. The priority applies to inbound
traffic on the port. The default priority of each port is 0.
To change the QoS priority of port 1/1 on a device to queue 2, enter the following commands.
BigIron RX(config)# interface ethernet 1/1
BigIron RX(config-if-e1000-1/1)# priority 5
Syntax: [no] priority <num>
The <num> parameter can be from 0 – 7 and specifies the priority level equivalent to one of the
four QoS queues.
Changing a Layer 2 port-based VLAN's priority
By default, VLANs have priority 0. To change a port-based VLAN's QoS priority, use one of the
following methods. The priority applies to inbound traffic on ports in the VLAN.
To change the QoS priority of port-based VLAN 20 to queue 3, enter the following commands.
BigIron RX(config)# vlan 20
BigIron RX(config-vlan-20)# priority 7
Syntax: [no] priority <num>
The <num> parameter can be from 0 – 7 and specifies the priority level equivalent to one of the
four QoS queues.
Assigning static MAC address entries to priority queues
By default, all MAC address entries are in the best effort queue. When you configure a static MAC
entry, you can assign the entry to a higher QoS level using the following method. The priority applies
to packets sourced by this MAC address.
To configure a static MAC entry and assign the entry to the premium queue on a device, enter
commands such as the following.
BigIron RX(config)# vlan 9
BigIron RX(config-vlan-9)# static-mac-address 1145.1163.67FF ethernet 1/1
priority 7
Syntax: [no] static-mac-address <mac-addr> ethernet <slot>/<portnum> [priority <num>]
The <num> parameter can be from 0 – 7 and specifies the priority level1 equivalent to one of the
four QoS queues.
