Availability and redundancy

o
Virtual Router Redundancy Protocol (VRRP) for Layer 3 router redundancy
o IEEE 802.1D STP for providing L2 redundancy
o
IEEE 802.1s Multiple STP (MSTP) for topology optimization, up to 32 STP instances are
supported by a single switch
o IEEE 802.1w Rapid STP (RSTP) provides rapid STP convergence for critical delay-sensitive
traffic like voice or video
o Per-VLAN Rapid STP (PVRST) enhancements
o
Layer 2 Trunk Failover to support active/standby configurations of network adapter teaming on
compute nodes
o
Hot Links provides basic link redundancy with fast recovery for network topologies that require
Spanning Tree to be turned off
VLAN support

o
Up to 4095 VLANs supported per switch, with VLAN numbers ranging from 1 to 4095 (VLAN 4095
is used by the management network.)
o
Port-based VLANs
o 802.1Q VLAN tagging support
o
Private VLANs support
Security

o
VLAN-based, MAC-based, and IP-based access control lists (ACLs)
o 802.1x port-based authentication
o Multiple user IDs and passwords
o User access control
o Radius, TACACS+ and LDAP authentication and authorization
o NIST 800-131A Encryption
o Selectable encryption protocol
Quality of Service (QoS)

o Support for IEEE 802.1p, IP ToS/DSCP, and ACL-based (MAC/IP source and destination
addresses, VLANs) traffic classification and processing
o Traffic shaping and re-marking based on defined policies
o
Eight output Class of Service (COS) queues per port for processing qualified traffic
o IPv4/IPv6 ACL metering
