Converged Infrastructure Lan Switches; X330 Wan Module - Avaya Application Solutions Deployment Manual

Converged infrastructure LAN switches

P330 family
By default, P330 LAN switches accept 802.1Q frames on all ports, and use the 802.1p priority
tags. There are two queues within the P330s. The high-priority queue represents 802.1p values
4 to7. The low-priority queue represents 802.1p values 0 to 3. In addition to accepting the
values tagged by an endpoint, tagging can be done per port with the command:
set port priority <high|low>

X330 WAN Module

The new X330WAN versions contain a predefined queue management strategy for IP
Telephony that is called CBQ. Use the following procedure to activate CBQ:

Examples of QoS implementation
Meaning
Define DSCP-CoS mapping.
set up access-list 100 with name "voice".
The X330 WAN has four queues with eight
behaviors. fw6 and fw7 are different
behaviors within the top strict priority queue.
In access-list 100, map DSCP 46 to the fw6
queue.
Trust packet tagging.
Activate the above mapping on ingress
traffic to the Fabric Fast Ethernet interface
Apply the ACL to traffic that is arriving on
the FabricFastEthernet port.
