This example maps the IEEE 802.1p priorities to only 4 switch queues. Since switch queue 3 is
always mapped to IPQoS Q0, if you map IEEE 802.1p priority 7 to switch queue 3, and set 2 IPQoS
queues, the system maps all of the IEEE 802.1p priorities to Q0 and does not use Q1.
• With 2 IPQoS queues, Q1 is used.
• With 4 IPQoS queues, Q2~Q3 are not used.
• With 8 IPQoS queues, Q4~Q7 are not used.
Here is another example. This one maps the IEEE 802.1p priorities to only 3 switch queues.
• With 2 IPQoS queues, Q1 is not used.
• With 4 IPQoS queues, Q1 is not used.
• With 8 IPQoS queues, Q1~Q4 and Q6 are not used.
11.24 Access Control List (ACL) Overview
An ACL (Access Control List) profile allows the system to classify and perform actions on the
upstream traffic. Each ACL profile consists of a rule and an action, and you assign ACL profiles to
PVCs.
•Use the Profile > ACL screen (Section 11.25 on page 403) to configure the ACL profiles.
•Use the ACL > Rule screen (Section 4.16 on page 115) to assign the ACL profiles to PVCs.
