Product Overview

The Enterasys B3 is a high-performance, Gigabit Ethernet edge switch that provides scalable,

wire-rate performance in support of the bandwidth-intensive and delay-sensitive requirements of

today’s demanding applications. With support for 16,000 MAC addresses, the B3 is an excellent

choice for environments that require complete multi-layer switching capabilities and support for

high density 10/100/1000 Ethernet ports and static routing capabilities. The B3 is well-suited

for Gigabit Ethernet networks as well as 100 Mbps networks that may migrate to a predominantly

Gigabit Ethernet network. In addition to its complete multi-layer switching capabilities, the B3 also

provides basic routing features, including RIP, static IPv4 routing, and IPv6 management support.

Along with a switch capacity of 144 Gbps, the B3 provides up to 48 10/100/1000 Ethernet ports

as well as 4 Gigabit Ethernet uplink combo ports. Leveraging the B3’s wire-rate stacking capability,

as many as 8 B3s (both 24-port and 48-port combinations) can be interconnected in a single stack

to create a virtual switch that provides 1.15 Tbps of capacity and up to 384 10/100/1000 Ethernet

ports as well as 32 Gigabit Ethernet uplink combo ports.

Robust Quality of Service (QoS) features enable strong support for integrated multimedia networks,

including Voice over IP (VoIP) and video, as well as all types of data-intensive applications. The

B3’s optional policy license enables its highly customizable Layer 2/3/4 packet classiﬁcation

capabilities to work together with the 8 hardware-based priority queues associated with each

Ethernet port to support a suite of differentiated services with as many as 8 distinct priority levels.

In conjunction with its non-blocking L2 switching and L3 routing architecture, the B3’s intelligent

queuing mechanisms ensure that mission-critical applications receive prioritized access to

network resources.

The B3 provides a secure network by utilizing its authentication and security features, which can be

applied at the port level or at the user level. Making use of the NMS Policy Manager or a standard

CLI, the Enterasys role-based architecture enables a network administrator to deﬁne distinct roles

or proﬁles that represent operational groups within a business (e.g., employee, executive, guest,

etc). Multiple users/devices per port can be authenticated via IEEE 802.1X, MAC address, or web

authentication, and then assigned a pre-deﬁned operational role. Network operations can be easily

tailored to meet business-oriented requirements by providing each role with individualized access

to network services and applications (e.g., a guest should have different network access privileges

than an employee).

There is nothing more important

than our customers.
