SuperStack II Switch 3800

10/100/1000 Mbps Ethernet Layer 3 Switching

The SuperStack II Switch 3800 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 broadcast/multicast traffic and fault propagation are kept under control in appropriate subnetworks.

The SuperStack II Switch 3800 not only aggregates the traffic from Ethernet and Fast Ethernet workgroups to a server farm or a corporate backbone through an optional Gigabit Ethernet high-speed link, 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:

■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

■ 24 10/100 Mbps Ethernet/Fast

Ethernet autosensing ports

■ One Gigabit port (1000BASE-SX)

enabled by an optional SuperStack II

Switch 3800 GBIC (gigabit interface

connector). A second GBIC can be

plugged in to provide additional

physical resilience.

■ Full line-rate nonblocking routing

performance on all ports (over

5 million IP packets per second and

8.7 Gbps throughput)

■ Support for standards-based routing

For a dramatic performance boost in corporate routed networks, the SuperStack II Switch 3800 delivers wire-speed IP routing embedded in ASIC technology through 10/100/1000 Mbps Layer 3 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.
