Features
Features Performance: 8.8 Gbps, max.; wirespeed performance across ports
Layer 2 switching: full-rate nonblocking on all ports, full-/half-duplex autonegotiation, flow control, IEEE 802.1Q VLAN support, IEEE 802.1p traffic prioritization, IGMP snooping; more
Convergence: 4 hardware queues per port; traffic prioritization at Layer 2 (802.1p) and at Layer 3 (TOS with DSCP); auto-VLAN assignment for voice traffic; more
Power over Ethernet: IEEE 802.3af; 180W per switch, max.
Switch management: Web-based configuration, SNMP management

Web-managed Layer 2 10/100 Ethernet switch
PoE provides power for IP phones, wireless LAN access points, and other compliant devices over the same cable used for data
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 completely redesigned 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 manual link aggregation, 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
Rapid Spanning Tree Protocol (RSTP) support improves network compatibility, scalability and availability
IGMP snooping and query and multicast filtering optimizes network performance
