IGMP filtering to control multicast traffic for hosts participating in multicast groups
Configurable traffic distribution schemes over trunk links based on source/destination IP or MAC
addresses, or both
Fast port forwarding and fast uplink convergence for rapid STP convergence
Availability and redundancy
Virtual Router Redundancy Protocol (VRRP) for Layer 3 router redundancy

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
