Specification Sheet

Feature

Description

Quality of service

Priority levels

8 hardware queues

Scheduling

Strict priority and Weighted Round-Robin (WRR) queue assignment based on DSCP and

class of service (802.1p/CoS)

Class of service

Port based; 802.1p VLAN priority based; IPv4/v6 IP precedence/Type of Service

(ToS)/DSCP based; Differentiated Services (DiffServ); classification and re-marking ACLs,

trusted QoS

Rate limiting

Ingress policer; egress shaping and rate control; per VLAN, per port, and flow based

Congestion avoidance

A TCP congestion avoidance algorithm is required to reduce and prevent global TCP loss

synchronization
