3Com Switches warranty SuperStack II Switch 9000 Gigabit Ethernet Layer 3 Switching

The SuperStack II Switch 9000 offers affordable leading-edge Layer 3 switching technology for 10 times the performance of intranets. Wire-speed Layer 3 switching (IP routing) and Layer 2 switching are embedded in ASICs to forward at nonblocking speed any-to-any intranet traffic while broad- cast/multicast traffic and fault

propagation are kept under control in appropriate subnetworks.

The SuperStack II Switch 9000 not only aggregates at Gigabit speed the traffic from Ethernet and Fast Ethernet workgroups, but it removes router bottlenecks that occur in corporate networks when high-speed, any-to-any intranet traffic chokes software-based legacy routers.

Key features include:

■Full line-rate nonblocking routing performance on all ports (over 11.9 million IP packets per second and 17.7 Gbps throughput)

8 x 1000BASE-SX ports

■IEEE 802.3x flow control on all full- duplex ports to improve performance and minimize packet losses

■Full VLAN implementation:

–Port and tagged VLANs (802.1Q)

–Protocol-based VLANs to allocate bandwidth and enforce manage- ment policies among different protocols (e.g., IP, IPX, NetBIOS, DECnet)

■User-definable packet filters to control traffic flows

■Support for spanning tree per VLAN

■Class of Service embedded in ASIC PACE technology, 802.1D (incorporating 802.1p)

■RMON support for four groups

■Simplicity and scalability of 10/100/1000 Ethernet in the industry-leading SuperStack II system architecture

For dramatic performance boost in corpo- rate routed networks, the SuperStack II Switch 9000 delivers wire-speed IP routing embedded in ASIC technology in addition to Gigabit Ethernet switching.

It offloads the routing of intranet traffic from slow legacy routers while keeping under control broadcast/multicast traffic and fault propagation in appropriate subnetworks.
