Security
Advanced security for network data and
management traffic controlling a network.
Advanced security for network data and
management traffic controlling a network.
User network login with IEEE 802.1X
and RADIUS, combined with RADIUS
Authenticated Device Access (RADA),
provides secure flexible network access
control at the edge of the network. Local
authentication for up to 50 IEEE 802.1X
users and RADA devices offers added
flexibility in the absence of a centralized
RADIUS server, and supplies a backup
solution in case of server failure or
connectivity issues.

Authenticated users can be placed auto-
matically into a specific VLAN, restricting
access further. The Private Ports feature can
isolate edge ports to ensure user privacy.
Access Control Lists (ACLs) allow or deny
traffic based on specific subnet, or individual
IP address. SNMP v3 secure encrypted
management, Secure Shell (SSH), manage-
ment VLAN, and management station
"trusted IP address" lists help protect the
network from rogue management threats.

Resiliency
Hot-swappable stacking of up to eight units,
or 384 10/100 ports, allows continuous
operation of the network. Stack-wide link
aggregation (LACP) enables high-perform-
ance connectivity of up to 4Gbps to the core
of the network, with up to four ports from
different units aggregated together across
the stack to maximize network uptime.

Network Control
Network management is available through
an embedded web and command line
interface (CLI), or via an SNMP management
station. Supported by the range of 3Com
management offerings including 3Com
Network Supervisor.

Multilayer Traffic Shaping
Advanced Multilayer packet classification
enables prioritization of mission critical
traffic and real-time applications, while
freeing bandwidth by eliminating unwanted
protocols and applications from the network.
Through network login profiles, classifica-
tion can be dynamically assigned on a per-user
basis. Port based rate-limiting enables the
maximum bandwidth on each port to be
limited, allowing maximum control of
network resources while maintaining the
full benefit of the powerful traffic
prioritization features.

Ease of Use
The switches automatically select the optimal
speed and duplex mode of connected cables
to prevent mis-configuration of the network.
They also detect and adjust to cross-over
or straight-through cable connections—a
feature called auto MDI/MDIX—eliminating
the need for specific cables.
