Switch GH2008

Performance

All wire-speed forwarding, non-congestion design

3.2/6.4/9.6 Gbps switch fabric, dedicated ASIC for switching

Security and reliability

Local security policy restricts illegal access

IEEE 802.1x port-based user authentication

Port trunking increases bandwidth and redundancy

Easy maintenance

Automatic recognition for straight-through or cross-over cables

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

Management via CONSOLE port, SNMP, Web, 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
