Auto Mdi/Mdix; Mac Addresses; Igmp Snooping; Spanning Tree Protocol - Nortel BayStack 380 model 24T Specifications

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 hard-
ware at line rate, and pruning unwanted data
streams from affecting network or end-
station 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 speci-
fied port for ingress or egress.

Control
This feature allows you to control traffic
and avoid congestion on the gigabit full-
duplex 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.

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.
