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 core of the
network.

Flexibility
Available in managed 50- or 26-port
configurations, with 48 or 24 auto-sensing
10/100 ports and two dual-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
feature called 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
a network. 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 network into more secure areas.

Management of the switch can be
implemented using Secure Shell (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 Network Supervisor for
configuration and troubleshooting
of multiple devices on the network.
