●
Optimal platform to support real-time applications such as voice and video by providing
features such as IGMP snooping, multiple queues (4) with appropriate scheduling
techniques, prioritization of traffic based on port, 802.1p, IP ToS/precedence/DSCP, and
line rate forwarding mechanisms
●
Enhanced QoS functions, including rate limiting for ingress/egress and per flow at 64 kbps
granularity
●
HTTP interface
●
User/network security via 802.1x (with RADIUS authentication) and MAC-based filtering
●
Containment of storms - broadcast and multicast
●
Expandability and availability increased across multiple switches using link aggregation
●
Port trunking for up to eight groups with up to eight ports per group allows you to increase
your bandwidth for each uplink or server connection
●
Simple Network Management Protocol (SNMP) and Remote Monitoring (RMON)
management expand your visibility options
