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:
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
protocols: RIP/RIP v2
Support for up to 12,000 MAC
addresses for handling networks of
virtually any size
Elastic port buffering to enable
on-the-fly allocation of memory for
automatic performance optimization
based on network traffic
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
