Switch GH2108

Performance

8/24 Gbps switch fabric, non-congestion design, all wire-speed forwarding

80-km transfer by Gigabit optical fiber, direct connection to WAN

Security and reliability

Quota system for connected hosts per port

IEEE 802.1x port-based user authentication

Port trunking adds to bandwidth and redundancy

Easy maintenance

Automatic recognition for straight-through or cross-over cables

Stackable physically and through cluster technology. Central management with unified IP address saves IP addresses

Management via CONSOLE port, Web, SNMP, Telnet, etc

Software and BootRom upgrade through TFTP

Traffic and broadcast control

Auto-detection and restraining of broadcast storm, IGMP snooping, effectively restrict broadcast flooding

Full- and half- duplex traffic control

Ethernet port rate limiting with 64 K step size(1 M step size for rate over 1.8 M)

Advanced buffer management, 802.1p support. 4 dispatching queues per port, mapping the 8 priority queues in 802.1p

QoS support
