Chapter 11 Profile Screens

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.

Table 185 IEEE 802.1p to IPQoS Modified Queue Mapping Example

• 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.

Table 186 IEEE 802.1p to IPQoS Modified Queue Mapping Example

• 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

• Use the Profile > ACL screen
