Scalability
Enhanced 10/100/1000 Layer 2 switching
and dynamic Layer 3 routing solution
delivers scalable wirespeed Gigabit perform-
ance, with integrated stacking up to eight
units high, or 384 Gigabit ports. Each Switch
comes with integrated dual full duplex
10Gbps stacking ports on the back of the
unit, providing a total stacked capacity of
40Gbps, plus an expansion slot capable of
supporting an additional 10Gbps full duplex
(20Gbps total) high-speed Ethernet connec-
tion. This enables the 156Gbps switching
capacity to provide wirespeed switching on
all ports.
Stack-wide link aggregation enables high-
performance connectivity to the core of the
network, with up to eight ports from
different units aggregated together to
improve resiliency and uptime.
Performance
24 or 48 built-in copper Gigabit ports,
including four dual-purpose ports
supporting copper links or SFP adapters for
easy, flexible connection to fiber based
Gigabit media. Port-based rate-limiting
enables the bandwidth on each port to be
restricted, so power users can receive the
full bandwidth available while non-key users
can be throttled down, preserving network
bandwidth and allowing maximum control
of network resources. Built-in packet priori-
tization gives optimal performance to
real-time applications such as voice and
video.
Future Protection
Gigabit to the desk prepares your network
for the future at prices comparable to those
of some 10/100 switches. Tri-speed opera-
tion at 10-, 100-, and 1000Mbps allows easy
migration to Gigabit speeds. Investment
protection is further enhanced with
switching silicon designed to support multi-
layer switching, and a module slot that
supports a single-port 10-Gigabit Ethernet
module, with CX-4, LR, or ER XENPAK ports
that can be used to connect back to the
network core.
Ease of Use
Dynamic routing with RIP (Routing
Information Protocol) allows automatic
updating of Layer 3 network topologies.
Speed and duplex mode on all ports are
negotiated automatically, preventing the
possibility for improper configuration.
Switches detect and adjust to cross-over or
straight through cable connections via “Auto
MDI/MDIX” feature, eliminating the need
for different cables to interconnect network
devices.
Security
The Switch 3870 family ensures secure
access to resources using standard 802.1X
network access control combined with
RADIUS authentication. Additionally,
RADIUS Authenticated Device Access
(RADA) enables authentication of attached
devices via MAC address for an additional
level of endpoint security. Port-based
Access Control Lists (ACLs) effectively
enable usage policies at each point of access
to the network via the switch.
Secure Shell (SSHv2), Secure Sockets Layer
(SSL/HTTPs) and SNMPv3 support ensure
secure management access to switches via
authentication and encryption of manage-
ment traffic.
Powerful Management
Comprehensive support within the 3Com
management application software suite,
including the standalone packages 3Com
Enterprise Management Suite or 3Com
Network Director. 3Com Network
Supervisor may also be used in smaller
networks.
