Queuing and scheduling
The GbE2 has eight output Class of Service queues (COSq) per port (0-7), 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.
Class Of Service queues 0 - 6 use Weighted Round Robin (WRR) scheduling, with user configurable weight from
1 to 15. The weight of 0 (zero) indicates strict priority, which might starve the low priority queues. Queue 7 is a
high-priority queue, and always has a weight of 0 (zero).
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.
• Define the number of COS queues available (2 or 8).
Use the 802.1p menu (/cfg/qos/8021p) to configure Class Of Service queues.
