Feature

Description

Quality of Service

Priority levels

8 hardware queues

Scheduling

Strict priority and Weighted Round-Robin (WRR)

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 remarking ACLs,

trusted QoS

Queue assignment based on DSCP and class of service (802.1p/CoS)

Rate limiting

Ingress policer; egress shaping and rate control; per VLAN, per port, and flow based; 2R3C

policing

Congestion avoidance

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

synchronization

iSCSI traffic optimization

A mechanism for giving priority to iSCSI traffic over other types of traffic
