ASCII Configuration File
The Ethernet Switch 470 can download
a user-editable ASCII configuration file
from a Trivial File Transfer Protocol
(TFTP) server. The ASCII configuration
file can be loaded automatically at boot
time or on-demand using the manage-
ment systems (console menus or CLI).
Once downloaded, the configuration
file automatically configures the switch
or stack according to the CLI commands
in the file. This feature allows the flexi-
bility of creating command configuration
files that can be used on several switches
or stacks with minor modifications.
ASCII Configuration Generator
The ASCII Configuration Generator
allows the configuration settings of the
switch to be displayed or 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 a switch from an
external file server.
Power Redundancy
Redundant power support
With connectivity to the RPS15, the
Ethernet Switch 470 delivers redundant
power supply support crucial in mission-
critical environments. Nortel’s RPS15
Power Supply Unit is capable of having
up to three 600-watt power supply
modules. Each power module can
provide redundant power supply
support to one 470-PWR or up to four
470 switches. A DC cable connector
cable is required to connect from an
Ethernet Switch 470 to an RPS15
module (see ordering information section
for order numbers). The Ethernet
Switch 470 also requires a DC-to-DC
converter.
New Ethernet Switch
software features
The Ethernet Switch Software Release
3.6.2 for Ethernet Switch 470 supports
these new features:
VLACP Messages
This feature generates a system log and
SNMP trap messages when Virtual Link
Aggregation Control Protocol (VLACP)
enables or disables a link. This enables
administrators to determine the status of
links configured with VLACP for health
checking.
STP BPDU-Filtering
This release supports the BPDU-Filtering
feature for Spanning Tree Protocol. Based
on the BPDU information exchange,
selection of a root bridge occurs. Typically,
when a new bridge joins the spanning
tree or an existing bridge leaves the
spanning tree, the root selection process
is repeated and a new root is selected (if
appropriate).
The BPDU-Filtering feature allows the
network administrator to block an
unwanted root selection process when
an edge device is added to the network.
This prevents unknown devices from
influencing an existing spanning tree
topology. When a port has BPDU-
Filtering enabled and it receives an STP
BPDU, the port is immediately put in
the operational disabled state. A trap
message is generated and a message is
written to the switch log. The port stays
in the operational disabled state until
the port timer expires (this timer is
configurable by the switch administrator).
Web-based Management for
RSTP, MSTP and LACP
This release provides Web-based manage-
ment support for Rapid Spanning Tree
Protocol (IEEE 802.1w), Multiple
Spanning Tree Protocol (IEEE 802.1s)
and Link Aggregation Control Protocol
(LACP) (IEEE 802.3ad).
MLT Shutdown Ports on Disable
The MLT shutdown ports on disable
feature is used to prevent broadcast
storms when an MLT is disabled and
some or all of its ports are still
connected to another device. The
feature enabled all ports that are
members of the MLT to be automati-
cally shut down when the MLT is
disabled and then generates a trap
message. When enabling an MLT
group, then any disabled ports are
enabled automatically when this feature
is enabled. This feature is user-config-
urable and is disabled by default, so that
the default behavior remains the same as
previous releases.
Lifetime warranty
All Ethernet Switch 470 models offer a
lifetime warranty. Enterprises demand
quality products and companies that
stand behind them. A Nortel product
hardware warranty is supported for as
long as the original end user continues
to own or use the product, including
fan and power supply. In the event of a
discontinuance of product manufacture,
the Nortel warranty support is limited
to five (5) years from the announcement
of discontinuance.
