Key Benefits
Performance
Wirespeed, non-blocking Layer 2/3
switching for 10/100 desktop connections
with built-in Gigabit downlinks. Packet
prioritization gives optimal performance to
real-time applications such as voice and
video. Link aggregation of the downlinks
enables high-performance connectivity to
the core of the network, with resiliency to
improve availability and uptime. Layer 3
switching at the edge enables fast switching
of traffic between local subnets while
offloading routers in the coreof the
network.
Flexibility
Available in managed 50- or 26-port
configurations, with 48 or 24 auto-sensing
10/100 ports and twodual-personality
ports for 10/100/1000 or SFP connectivity.
Ease of Use
Supports dynamic routing through RIP,
with automatic updating of the Layer 3
network without any manual intervention.
Much easier than implementing static
routes.
Automatically auto-negotiates speed and
duplex mode of cables connected to it
preventing misconfiguration of the network.
Switches detect and adjust to cross-over or
straight-through cable connections– a
featurecalled auto MDI/MDIX– eliminating
the need for specific crossover cables.
Scalability
Supports up to 2,000 external routes,
allowing the switch to scale as the network
grows–ideal for deployments at the edge of
anetwork. Supports up to 255 VLANs and
standards-based IEEE 802.3ad trunking
(LACP).
Rate limiting enables the bandwidth on
each port to be restricted, preserving
network bandwidth and allowing
maximum control of network resources.
Security
Supports IEEE 802.1X network login to
secure user entry into the network, with
access control directed from a central
standards-based RADIUS server for ease of
management. Intrusion prevention features
protect the network and will discard all
packets from unauthenticated users.
Port-based Access Control Lists further
enhance security.Communication of
attached stations can be restricted to
certain destinations,in essence segmenting
the networkinto moresecureareas.
Management of the switch can be
implemented using SecureShell (SSH)
and Secure Sockets Layer (SSL/HTTPS)
encryption (56 or 168 bit) preventing
unauthorized remote access to the switch
over IP networks or from a web browser.
Network Control
Network management through embedded
web interface, command line interface, or
an SNMP management station. Network
management is further simplified with the
use of 3Com NetworkSupervisor for
configuration and troubleshooting
of multiple devices on the network.

3Com®SuperStack®3Switch 3200 family
switches are wirespeed, Layer 3 switches
with 10/100 desktop connections and Gigabit
downlinks for high performance connectivity
to the rest of the network. These switches
support dynamic Layer 3 routing, simplifying
the implementation of Layer 3 networks by
automatically configuring and updating the
switch with all topology changes. This ability
to dynamically reconfigure the routing
provides a significant benefit over the use of
static routes, avoiding the drawback of many
Layer 3 switches which require manual
intervention when changing the topology
of the network.
The SuperStack 3 Switch 3200 is optimized
for edge desktop connections. Layer 3
switching for the network’s edge, with the
Switch 3200’s hardware-based wirespeed
routing, improves performance by routing
locally without data having to travel back to
the network core. This is especially useful in
organizations having or anticipating multiple
subnets in their workgroups, where even
local traffic mayotherwise need to be routed
via a core switch.
Also, for edge-optimized deployment, the
SuperStack 3 Switch 3200 supports the
learning of up to 2,000 IP routes through an
uplink to a core router using Router Internet
Protocol (RIP). This high number of routes
enables the switch to operate in larger
networks than can other switches which
have significantly smaller numbers of routes.
The SuperStack 3 Switch 3200 also supports
core-level switching in smaller networks,
with local routing for 32 IP interfaces and up
to 14 routes distributed from other local
Layer 3 devices.
The SuperStack 3 Switch 3200 family
confirms 3Com’s commitment to strong
network security. Its implementation of
IEEE 802.1X network login security helps
ensure all users are authorized before being
granted access to any network resource.
User authentication is carried out using any
standards-based RADIUS server, avoiding
any proprietary authentication mechanisms.
Containment of users to specific areas of
the network can be easily controlled through
Access Control Lists (ACLs), restricting the
IP addresses with which a port can commu-
nicate.
