Brocade FastIron Ethernet Switch Traffic Management Guide - Manual (Page 30)

The device assigns priority 7 to untagged switched traffic received on port 1/1.
Use the following command to assign priority levels.
Syntax: [no] priority num
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 the QoS queues table.
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.
device(config)#vlan 9
device(config-vlan-9)#static-mac-address 0000.0063.67FF ethernet 1/1 priority 7
device(config-vlan-9)#write memory
Use the following command to configure a MAC entry and assign the entry to a priority queue.
Syntax: [no] static-mac-address mac-addr ethernet port [ priority num ]
The mac-addr is the MAC address.
The prioritynum variable can be from 0 through 7 and specifies the IEEE 802.1 equivalent to one of
the eight QoS queues.
Buffer allocation and threshold for QoS queues
By default, Brocade IronWare software allocates a certain number of buffers to the outbound transport
queue for each port based on QoS priority. The buffers control the total number of packets permitted in
the outbound queue for the port. If desired, you can increase or decrease the maximum number of
outbound transmit buffers allocated to all QoS queues, or to specific QoS queues on a port or group of
ports. For more information, refer to the FastIron Ethernet Switch Platform and Layer 2 Switching
Configuration Guide.
NOTE
On ICX 6650 devices, you cannot increase or decrease the maximum number of outbound transmit
buffers allocated to all QoS queues, or to specific QoS queues on a port or group of ports.
802.1p priority override
You can configure a port to ignore the 802.1p priority for traffic classification for an incoming packet.
When this feature is enabled, packets will be classified as follows:
• If the packet matches an ACL that defines the priority, then ACL priority will be used.
• If the packet source or destination MAC address matches a configured static MAC address with
priority, then static MAC priority will be used.
• If the ingress port has a configured priority, then port priority will be used.
• If the other situations do not apply, the configured or default port priority (0) will be used.
