Queuing and scheduling

The switch can be configured with either two or eight output Class of Service queues (COSq), into which each packet is placed. Each packet’s 802.1p priority determines its COSq, except when an ACL action sets the COSq of the packet.

Each COS queue uses Weighted Round Robin (WRR) scheduling, with user-configurable weight from 0 to 15. The weight of 0 (zero) indicates strict priority, which might starve the low priority queues.

You can configure the following attributes for COS queues:

•Map 802.1p priority value to a COS queue.

•Define the scheduling weight of each COS queue.

Use the 802.1p menu (/cfg/qos/8021p) to configure Class of Service queues.
