The BayStack 380-24F Switch

Nortel Networks BayStack* 380 Switches
are designed to provide high-density, high­bandwidth connectivity to desktops, other
switches, servers, and other network devices.
BayStack 380 Switches offer a resilient
solution that minimizes capital and opera­tional expenses. Their robust security
features offer protection against unautho­rized access to data traffic. The switches are
Web-manageable and support Redundant
Power Supply (RPS) and Uninterruptible
Power Supply (UPS) options. BayStack
380 Switches are available in two models—
BayStack 380-24T and BayStack 380-24F
(Figure 1).

BayStack 380-24T—
High-density desktop switching
and server aggregation

The BayStack 380-24T Switch has 24
10/100/1000 Mbps auto-sensing ports and
four SFP (Small Form Factor Pluggable)
GBIC (Gigabit Interface Converter) ports. It
provides high-density Gigabit connectivity
to power-user desktops for high-speed appli­cations such as graphics, multimedia and
CAD/CAM, as well as server farm aggrega­tion (Figure 2). Ports 21 through 24 may be
configured as either 10/100/1000 BASE-TX
ports or SFP GBIC ports in any combination.
The BayStack 380-24T is ideal for mid-size
and large businesses that have a need for
high bandwidth to the desktop.

BayStack 380-24F —
High-density wiring closet
switch aggregation

The BayStack 380-24F Switch with 20 SFP
(Small Form Factor Pluggable) ports and
four full-sized GBIC (Gigabit Interface
Converter) ports is an ideal switch for
high-density wiring-closet Layer 2 aggre­gation. BayStack 470-48T stacks or
BayStack Business Policy Switch/BayStack
450 stacks can be collapsed into the
BayStack 380-24F using the uplink ports
on the wiring closet switches

(Figure 3).
The GBIC ports offer an unmatched flexi­bility of fiber connection types including
SX, LX, ZX, and XD as well as CWDM.
In addition, copper GBIC is also supported.
The BayStack 380-24F’s high-density
design results in lower per port price than
its competitors. The BayStack 380-24F is
ideal for small and mid-size businesses
that need simple and cost-effective Layer 2
aggregation.

Product Brief

2

The SNMPv3 feature provides user
authentication and data encryption for
higher security. It also offers secure config­uration and monitoring.

Class of Service

BoSS v3.0 allows the BayStack 380 to
prioritize traffic based upon the Class of
Service/Diffserv Code Point (CoS/DSCP)
of IP packets. The switch prioritizes LAN
traffic based on Layer 2 802.1p value. It
also provides the capability to map the
DSCP values in the IPv4 frame to any of
four priority queues. If the frame is not an
IPv4 frame, DSCP mapping is not applica­ble and the 802.1p mapping or port-based
priority is used. The BayStack 380 allows
the user to map all 64 possible DSCP
values to any of the four priority queues.
The IPv4 frames will be forwarded according
to the CoS queue priorities. Frames can be
prioritized in strict round-robin or
weighted round-robin fashion. Class of
Service implementation enables prioritiza­tion of multimedia or latency sensitive
traffic, making possible integration of voice,
video, and data within the same network.

Redundancy

With connectivity to the BayStack 10
Power Supply Unit (PSU) paired with a
–48V DC-to-DC converter module, the
BayStack 380 Switches deliver redundant
power supply support crucial in mission­critical environments. Uninterruptible
Power Supply (UPS) capability for
BayStack 380 Switches is supported
with the BayStack 10 PSU.

Security

The BayStack 380 Switches support
BaySecure*, which allows authentication
of all access, not only to the switches for
management and configurations but also
access to the infrastructure through these
switches. This software feature limits access
to only network authorized and trusted
personnel, including full tracking of
network connections. With BaySecure,
network access is granted or denied via
proper MAC-address identification.
In addition, with the Distributed Access
List Security feature, network access is
granted or denied on a per-port basis.
The BayStack 380 Switches also provide
Remote Authentication Dial-In User
Service (RADIUS) for switch security
management.

Multi-Link
Gigabit
Trunks

Multi-Link Trunking
for resiliency

Multi-Link Trunking (MLT) enables
grouping of links between the switch and
another switch or server to provide greater
bandwidth of up to 8 Gbps full duplex
with active redundant links for one trunk.
This feature also provides load-balancing
and automatic fail-over protection. Up to
six trunks are supported.

Passport 8600’s Split Multi-Link Trunking
(SMLT) eliminates single points of failure
in the network and allows the BayStack
380 to have multiple active connections to
the network core. The BayStack 380’s
ability to have multiple connections to
a Passport 8600 network core allows
customers to double their network band­width with no extra investment. The
Passport 8600 provides a self-healing
network which delivers the reliability and
availability required by today’s mission­critical applications.

BoSS (BayStack operating
system Switching Software)

BoSS v3.0 for Gigabit standalone switches
is a single software image exclusively for
the BayStack 380-24F and the BayStack
380-24T. With BoSS v3.0 for Gigabit
standalone switches, software upgrades are
simplified as the users need to download
only one set of software. This common
image provides the same software to all
user interfaces such as menu, Telnet, CLI,
WEB, and JDM.

BoSS v3.0 adds many new features includ­ing IGMP snooping, increased number of
VLANs, Class of Service/Diffserv Code
Point, CLI, ASCII configuration down­load, ASCII configuration generator, Single
Fiber Fault Detection, and a single software
image. In addition, BoSS v3.0 adds 10/100
management port and copper GBIC support
for the BayStack 380-24F switch.

3

MAC addresses

The BayStack 380 Switches support up to
32,768 MAC addresses for deployment of
large-scale enterprise networks with many
attached devices and workgroups, allowing
for scalability and cost effectiveness.

IGMP snooping

BoSS v3.0 provides IP Multicast support by
examining (‘snooping’) all Internet Group
Multicast Protocol (IGMP) traffic in hard­ware at line rate, and pruning unwanted data
streams from affecting network or end­station performance. IGMP snooping
enables the switch to selectively forward
Multicast traffic only onto ports where
particular streams are expected.

Spanning Tree Protocol

BayStack 380 Switches include built-in
support for Spanning Tree Protocol (IEEE

802.D) which detects and eliminates logical
loops in the network.

VLAN support

Up to 512 port-based VLANs can be
established for each switch to extend the
broadcast domain and segment network
traffic for greater efficiency. BayStack 380
supports up to 4095 VLAN IDs, but only
a maximum of 512 can be active at any
given time. BayStack 380 also supports
Independent VLAN Learning (IVL)
VLANs.

Jumbo frame support

Jumbo frame support of up to 9,216 bytes
is provided on each port for applications
requiring large frames such as graphics and
video applications.

Port mirroring

This feature, also known as conversation
steering, allows you to designate a single

switch port as a traffic monitor for a speci­fied port for ingress or egress.

Nortel Networks Command
Line Interface (CLI)

The CLI is used to automate general
management and configuration of
BayStack 380 Switches. The CLI is used
through a Telnet session or through the
serial port on the console.

ASCII Configuration Generator

The ASCII Configuration Generator
(ACG) allows the configuration settings of
the switch to be saved to an external ASCII
configuration file made up of a series of
CLI commands. This editable ASCII
configuration file can then be uploaded to
another switch from an external file server
to accelerate deployment.

802.3x High Speed Flow
Control

This feature allows you to control traffic
and avoid congestion on the gigabit full­duplex link. If a receive port buffer
becomes full, the switch issues a flow
control signal to the device at the other end
of the link to suspend transmission.

Auto MDI/MDIX

(BayStack 380-24T only)

The BayStack 380-24T Switch saves
money and time if it needs to be connected
to a hub or another switch. Normally, you
need a crossover cable for this purpose, but
with the BayStack 380-24T Switch you
can use an inexpensive straight through
cable or a crossover cable. The BayStack
380-24T is able to automatically detect the
energy on the cable and configure itself on
every port.
