Data Sheet

●

Optimal platform to support real-time applications, such as voice and video, by providing

features like IGMP snooping, multiple queues (four) 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

●

Increased expandability and availability across multiple switches using link aggregation

●

Port trunking for up to eight groups with up to eight ports per group, allowing 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
