Availability and redundancy
Virtual Router Redundancy Protocol (VRRP) for Layer 3 router redundancy
IEEE 802.1D STP for providing L2 redundancy
IEEE 802.1s Multiple STP (MSTP) for topology optimization, up to 32 STP instances supported
by single switch
IEEE 802.1w Rapid STP (RSTP) (provides rapid STP convergence for critical delay-sensitive
traffic like voice or video)
Per-VLAN Rapid STP (PVRST) enhancements
Layer 2 Trunk Failover to support active/standby configurations of network adapter teaming on
compute nodes
Hot Links provides basic link redundancy with fast recovery for network topologies that require
Spanning Tree to be turned off
VLAN support
Up to 1024 VLANs supported per switch, with VLAN numbers ranging from 1 to 4095 (4095 is
used for management module’s connection only)
802.1Q VLAN tagging support on all ports
Private VLANs
Security
VLAN-based, MAC-based, and IP-based ACLs

Quality of Service (QoS)
Support for IEEE 802.1p, IP ToS/DSCP, and ACL-based (MAC/IP source and destination
addresses, VLANs) traffic classification and processing
Traffic shaping and re-marking based on defined policies
Eight Weighted Round Robin (WRR) priority queues per port for processing qualified traffic
IP v4 Layer 3 functions
Host management
IP forwarding
IP filtering with ACLs, up to 896 ACLs supported
VRRP for router redundancy
