The SNMPv3 feature provides user
authentication and data encryption for
higher security. It also offers secure config-
uration 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 applica-
ble 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 prioritiza-
tion 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 mission-
critical 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 band-
width with no extra investment. The
Passport 8600 provides a self-healing
network which delivers the reliability and
availability required by today’s mission-
critical 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 includ-
ing IGMP snooping, increased number of
VLANs, Class of Service/Diffserv Code
Point, CLI, ASCII configuration down-
load, 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.
