- managed layer 2 gigabit ethernet switch - sixteen 10/100/1000 ports and 4 gigabit sfp ports, dual-purposed with 4 of the 10/100/1000 ports (configurable as 10/100/1000 or sfp); front-panel console port for cli management - auto-voice vlan automatically assigns voice over ip (voip) traffic to a voice-dedicated vlan, optimizing this delay-sensitive traffic - no need to configure the switch if default settings are acceptable - if more control desired, the switch interface allows even novice users to quickly and confidently configure the switch - vlans segment the network by grouping users based on their data or traffic requirements, making the best use of available bandwidth - with lacp link aggregation, automatically group ports together to form an ultra-high-bandwidth trunked connection to the network backbone and help prevent traffic bottlenecks - ieee 802.1x network access control provides standards-based security combined with local authentication - mac- and ip-based acls enable network traffic filtering and enhance network control - rapid spanning tree protocol (rstp) support improves network compatibility, scalability and availability - jumbo frame support for reduced network load - igmp snooping and multicast filtering optimizes network performance - switch can be managed with snmp-compatible software like 3com network supervisor and network director
