Using the Business Policy Switch 2000 Version 2.0
You enable or disable each policy using the pull-down menu under the Status
heading. The default value is Enabled.
Assigning mapping values
To manually configure the mapping among 802.1p priority values, priority, and
DSCP mapping, you must use with the following QoS Advanced pages:
• “Assigning 802.1p priority queue assignment” on page 341
• “Verifying DSCP mapping” on page 342
• “Assigning 802.1p user priority mapping” on page 345
• “Verifying DSCP queue assignments” on page 346
Assigning 802.1p priority queue assignment
You assign IEEE 802.1p priority values to a queue for specific queue set. This
information is used for assigning egress traffic to outbound queues.
To configure 802.1p priority:
1
Click the Application > QoS > QoS Advanced > Devices > Priority Q Assign
menu option.
The 802.1p Priority Queue Assignment page opens ( Figure 129 ).
Note: Nortel Networks recommends that you use the default mapping
values to ensure end-to-end QoS connectivity across Nortel Network
products.
Note: If you want to change the traffic class prioritization on a
BayStack 450 switch in a mixed stack configuration, use the 802.1p
Priority Queue Assignment page for queue set 2.
