BootP and TFTP support allows
centralized switch IP address assign-
ment, software upgrades and SNMP
agent updates over the network. The
RADIUS-based security feature uses the
RADIUS (Remote Authentication Dial-
In User Services) protocol to authenti-
cate local console and TELNET logins.
Command Line Interface (CLI)
The CLI is used to automate general
management and configuration of the
Ethernet Switch 470. The CLI may
be used through a Telnet/Secure Shell
session or through the serial port on
the console.
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.
Software 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).
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.
