SuperStack II Switch 9300

The SuperStack II Switch 9300 enables practical, cost-effective, and high- performance deployment of Gigabit Ethernet as an effective interswitch, switch-to-server, and general purpose backbone technology. As the highest den- sity Gigabit Ethernet (1000/1000 Mbps) switch available in a SuperStack II package, the SuperStack II Switch 9300 delivers full line-rate switching between its 12 Gigabit Ethernet ports to support

17.85million pps forwarding rate and 12 Gbps full-duplex throughput. Mul- tiple Gigabit Ethernet ports can

be trunked together to deliver up to

6 Gbps interswitch link. Full line-rate Gigabit Ethernet switching is supported on all ports via 25.6 Gbps switching fabric.

The SuperStack II Switch 9300 is available in three versions: a fixed

12-port fiber optic (12 x 1000BASE-SX) Gigabit Ethernet switch; a fixed 12-port fiber optic (10 x 1000BASE-SX and 2 x 1000BASE-LX) Gigabit Ethernet switch; and a fixed 12-port fiber optic (12 x 1000BASE-LX) Gigabit Ethernet switch. With the SuperStack II Switch 9300, you can interconnect high densities of Fast Ethernet switches that are attached to either dedicated desktops or shared segments and high-bandwidth network resources, such as servers.

Key features include:

■Supports up to 16,000 MAC addresses

■Multicast filtering using IGMP snooping

■Multicast throttling limits broadcasts and multicasts on a per-port basis

■Support for IEEE 802.3x flow control on all full-duplex ports

■Roving Analysis Port (RAP) for copying data from any port to another port with a network analyzer attached

■RMON support for four groups

■Fully standards-based 802.1Q VLANs, including GVRP support for automatic VLAN configuration distribution

■IEEE 802.1D (incorporating 802.1p) Class of Service support and dual pri- ority queuing

■Web browser interface for manage- ment and configuration functions

■Resilient links
