Enabling QoS Mode

Path: Network > QoS > LAN QoS Priority

Using the QoS page, you can enable Quality of Service (QoS) on the wireless controller.

Typically, networks operate on a best-eort delivery basis, which means that all trac has equal priority and an

equal chance of being delivered in a timely manner. When congestion occurs, all trac has an equal chance of

being dropped.

When you congure the QoS feature, you can select specic network trac, prioritize it according to its relative

importance, and use congestion-management and congestion-avoidance techniques to provide preferential

treatment. Implementing QoS in your network makes network performance more predictable and bandwidth

utilization more eective. It is especially useful if you expect trac congestion on the wireless controller LAN

ports.

QoS classication can be applied in Layer 2 or Layer 3 frames. For this reason, you can congure the wireless

controller to use Layer 2 CoS settings or Layer 3 DSCP settings.

Note: The wireless controller also provides a CoS-to-DSCP map to map CoS values in incoming packets to a DSCP

value that QoS uses internally to represent the priority of the trac. To access this feature, click Network > QoS > QoS

Priority.

To congure QoS mode:

1. Click Network > QoS > LAN QoS Priority.
