SWITCH 3870 10/100/1000 FAMILY DATA SHEET

Key Benefits

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.

Service

3Com products are backed by 3Com Global

Services and authorized partners with

demonstrated expertise in network assess-

ment, implementation, and maintenance.
