PCs and servers. All 24 ports of the
BayStack 460 Switch can be powered.
High-density Power over
Ethernet switch
The BayStack 460-24T-PWR Switch has
24 10/100 Mbps ports, one MDA (Media
Dependent Adapter) slot for uplink connectivity, and one cascade module slot for
stacking. Up to eight switches can be stacked
to achieve up to 224 10/100 ports (using
4-port 10/100 Mbps MDA per switch).
The 2.5 Gbps cascading bandwidth offers
dedicated bandwidth between switches
without sacrificing any uplink ports.
The uplink ports can be used for connections to backbone switches such as the
Passport 8600 Switch.
Part of the successful BayStack* family,
Nortel Networks BayStack 460-24T-PWR

and fault tolerance
IEEE P802.3af draft-compliant
The BayStack 460-24T-PWR Switch is
IEEE P802.3af draft-compliant. It can
provide Power over Ethernet to any IEEE
P802.3af draft-compliant devices such as IP
phones, wireless access points, net cameras,
security and lighting devices, and access
control devices. The benefit of being interoperable with standards-based equipment
means that customers are not forced to
tie themselves to any one vendor, as the
switch has the flexibility to power multiple
vendors’ devices. It can supply power up to
15.4 watts per port, which meets the IEEE
P802.3af standard. This is more than suffi-
cient to power most devices. The standard
is expected to be ratified in Q3, 2003.
Auto discovery feature
The BayStack 460-24T-PWR Switch automatically recognizes the connection of a
device and immediately sends power to it.
This automatic capability ensures fast
connectivity without manual intervention.
Dynamic power management
Each port can be configured to limit the
power delivered to a device. Each port can
also be configured for power priority level—
Low, High, and Critical. On the switch,
total available power is monitored. In the
case where all available power is fully utilized,
the switch may turn off lower priority ports
and turn on higher priority ports.
Active circuit protection
The BayStack 460 Switch can automatically
disable a port if there is a short. All the
other ports on the switch will remain
active and will not be affected by the
disabled port.
Plug-n-Play IP telephony
switching
The BayStack 460 Switch provides simplified
Web-based configurations on data and
power properties. The graphical user
interfaces make it simple to set up data
and power configurations.
Convenience of a single cable
With the BayStack 460 Switch, data and
power can be transmitted over one cable
without using a power outlet. There is no
need for a separate cable connecting the
IP device to a power outlet.
Significant space and
cost savings
Traditionally, a mid-span patch panel
device connects to a standard Ethernet
switch and the device sends power over
standard UTP cat 5 cable. In essence, two
units are needed for Power over Ethernet
capability. In contrast, the BayStack 460
Switch integrates standard LAN switch
functionality with the power over UTP
cable capability of a mid-span patch panel
into one unit. This results in significant
cost and space savings.
Fail-safe stacking
and resiliency
A key differentiation for the BayStack 460
Switch is its resilient stacking feature. The
BayStack 460 Switch can stack up to eight
units with a cascade stacking design, assuring continuous uptime even if a switch in
the stack should fail. A loop-back—or
redundant cascade cable—is used to seamlessly connect the entire stack to eliminate
any single point of failure (Figure 2).
MultiLink Trunking
MultiLink Trunking (MLT) enables grouping of links between the switch and another
switch or a server to provide greater bandwidth with active redundant links.
With Nortel Networks unique Distributed
MultiLink Trunking (DMLT) feature,
trunked ports can span multiple units of
the stack for fail-safe connectivity to missioncritical servers and the network center
(Figure 3). This can provide bandwidth of up
to 800 Mbps (when used with 10/100 ports)
or up to 8 Gbps (when used with Gigabit
uplink ports) with active redundant links in
one trunk. Up to six trunks are supported
per switch or stack.
Split MultiLink Trunking (SMLT) eliminates
single points of failure and allows wiring
closet switches, such as the BayStack 460,
to have multiple active connections to the
network core. The BayStack 460 Switch’s
ability to have multiple connections to a

Passport 8600 Switch Server
Passport 8600 network core allows customers
to double network bandwidth 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. By combining
the reliability of the Passport 8600 with the
resilient trunking features of the BayStack
460 (DMLT, MLT, etc.), Nortel Networks
offers the next generation of flexible
networking solutions (Figure 4).

Business Policy Switches, and BayStack 470
Switches.†A maximum of eight switches
can be stacked together in any combination.
to deploy the solution that is right for them
and offers the flexibility to implement
infrastructure changes at their own pace.
Figure 5 depicts an example of a smallto mid-sized enterprise solution with the
BayStack 460 Switch. Figure 6 shows
an example of a large enterprise solution.
MAC addresses
BayStack 460 Switches support up to
16,000 MAC addresses per switch or stack
for deployment of large-scale enterprise
networks with many attached devices and
workgroups, allowing for scalability and
cost-effectiveness.
VLAN support
Up to 256 port-based VLANs can be established for each switch, to extend the broadcast
domain and segment network traffic. The
256 VLANs can be spread among portbased, and MAC source address-based
VLANs (maximum of 48 MAC source
address-based VLANs). The 256 VLANs can
be on a standalone switch or across a stack.
Protocol-based VLANs allow switch ports to
be assigned to a broadcast domain, based on
the protocol information within the packet.
These VLANs can localize broadcast traffic
and assure that the specified protocol type
packets are sent only to the protocol-based
VLAN ports.
Shared VLAN (SVL) and individual VLAN
(IVL) learning is supported. With SVL
support, all VLANs in the switch share
the same forwarding database. IVL lets
individual VLANs have separate forwarding
databases within the switch. IVL allows the
switch to handle duplicate MAC addresses
if they are in different VLANs.
IGMP snooping
The BayStack 460 Switch features IP
MultiCast support by examining
(‘snooping’) all IGMP traffic in hardware
at line rate, and pruning unwanted data
streams from affecting network or end-station
performance.
Common software platform
All BayStack switches, including the
BayStack 460 Switch, have a common
“look and feel” which reduces training
costs. This allows the switches to be
managed in a similar fashion via a broad set
of management tools. These tools include
Web, Command Line Interface (CLI),
menus, Optivity Network Management
System (NMS), Optivity Switch Manager
(OSM), and Optivity Policy Services (OPS).
End-to-end Voice over IP
The BayStack 460 Switch provides enterprises
another option for end-to-end deployment
of Voice over IP. Succession Communication
Server for Enterprise 1000, Business
Communications Manager, Meridian, and
BayStack all provide the choices that allow
enterprises—from small and medium businesses to large campus infrastructures—

Multiple spanning tree
protocol groups
The BayStack 460 Switch supports multiple spanning tree groups (STGs). It
supports a maximum of eight STGs, either
all in one standalone switch or across a
stack consisting of several BayStack 460
Switches. Multiple STGs provide multiple
data paths, which can be used for loadbalancing and redundancy.
ASCII configuration file
The BayStack 460 Switch 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 management 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 flexibility of creating command
configuration files that can be used on
several switches or stacks with minor
modifications.
Security
The BayStack* 460 Switch features
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
users including full tracking of network
connections. With BaySecure, network
access is granted or denied by proper MAC
address identification (maximum of 448).
In addition, with the Distributed Access
List Security feature, network access is
granted or denied on a per port basis.
The BayStack 460 Switch also provides
Remote Authentication Dial-In User
Service (RADIUS) for switch security
management.
IP Manager List limits access to the management features of the BayStack 460 Switch
by a defined list of IP addresses, providing
greater network security and manageability.
SNMPv3 provides user authentication and
data encryption for higher security. It also
offers secure configuration and monitoring.
For even greater security, the BayStack 460
Switch also supports the IEEE 802.1x
standard (Extensible Authentication Protocol
or EAP). EAP limits access to the network
based on user credentials. A user needs to
“log in” to the network using username/
password; the user database is maintained on
the authentication server (not the switch). EAP
prevents network connectivity without password authorization for added security and
control in physically non-secure areas. For
example, banks, trading rooms, or classroom
training facilities could take advantage of this
feature. EAP supports client access to the
network and interoperates with Microsoft
Windows XP.
Web-based management
Web-based management using a Web browser
simplifies the task of managing the BayStack
460 Switch. This feature provides summary,
configuration, fault, statistics, application,
administration, and support pages for entire
stack. Traffic classification and prioritization
can be set via the Web-based QoS Wizard
and advanced configuration tool. Real-time
sampling provides up-to-date LED stats info
for stacked units. The Web interface also
allows for static configuration of numerous
parameters of the device.

Power sharing options
The BayStack 460 Switch can be used in
conjunction with the BayStack
10 PSU
or
NES
(Network Energy Source) DC Power System
from Invensys (www.intergynes.com) to
create a load sharing, RPSU, or UPS solution.
Load sharing
The BayStack 460 Switch provides up to
200 watts to power the devices. With the
addition of a BayStack 10 PSU, up to 235
watts of total power can be supplied to
devices. A 2-pin cable is required to connect
from the BayStack 460 to the BayStack 10
PSU. With the addition of NES DC power
system, up to 370 watts of total power can
be supplied to devices.
Redundant power supply unit support
Using a BayStack 10 PSU will provide up
to 75 watts of power to be supplied to
devices in case the power supply of the
BayStack 460 fails. A 2-pin cable is required
to connect from the BayStack 460 to the
BayStack 10 PSU. Using NES DC power
system, up to 200 watts of power can be
supplied to devices in case the power supply
of the BayStack 460 fails.
Uninterruptible power supply support
Using a BayStack 10 PSU will provide up
to 75 watts of power to be supplied to
devices in case there is an electrical outage.
Up to 15 minutes of battery life is provided
(this will vary depending on the amount of
modules installed on the BayStack 10).
Using NES DC power system, up to 200
watts of power can be supplied to devices
in case there is an electrical outage. With
NES system, up to 8 hours of battery life is
provided (this will vary depending on the
amount of modules on the NES unit).

Network management
On-box management
Network management begins with the
device. The BayStack 460 Switch supports
four groups of Remote Monitoring
(RMON) on all ports and is SNMPv3
compliant. The SNMP agent software
resides in the switch and uses the information it collects to provide management for
all ports in the stack. In addition, the agent
also provides the ability to set up policybased networks by supporting the Common
Open Policy Support (COPS) protocol.
†
Configuration management
The process of configuration begins with a
single device, but finishes across multiple
devices. Java Device Manager (JDM) is the
single device configuration tool for those
configuration functions that require communicating with a single device. JDM uses a
common user interface and workflow that
supports many Nortel Networks Ethernet
Switches. This commonality allows the
network manager to become familiar with
one tool instead of multiple tools.
Optivity Switch Manager (OSM) performs
the configuration function across multiple
devices. Configuration functions such as
VLAN assignments, MultiLink Trunking
(MLT), and Multicast are deployed across
multiple Nortel Networks Ethernet Switches.
The BayStack 460 Switch will be supported
in OSM version 3.0 in future releases.

Fault management and resolution
With Optivity Network Management System
(NMS), the network manager has quick
access to the information required to manage
and isolate all BayStack 460 networks
events. Tools such as Physical Topology
View inform the network manager how a
particular event is affecting the physical
connectivity within the network. End Node
Locate provides the ability to locate a failing
end node and, with one mouse click, have
access to the RMON statistics for the
failing Ethernet port supporting that end
node. These solutions provide visual and
statistical tools necessary to quickly resolve
any network event or to manage performance in real-time. The BayStack 460 will
be supported in NMS version 10.1 (future
release). In the meantime, there will be an
OIT (Optivity Integration Toolkit) file for
the BayStack 460 which can be used with
NMS 10.0.
Quality of Service
Quality of Service (QoS) is becoming
increasingly necessary as more of an organization’s critical business runs over the
network infrastructure. When you implement
the BayStack 460 Switch QoS features in
your network, you can utilize bandwidth
more efficiently, optimizing your existing
network resources and capabilities. If the
network is congested or down, if sales
people cannot submit orders, if e-mail and
intranet traffic threatens online Web transactions, or if new applications like voice and
video fail, your business could be negatively
impacted.
By classifying, prioritizing, policing, and
marking LAN traffic, networks can offer reliable connectivity and required bandwidth
for mission-critical applications like VoIP
to specific groups and users, as well as to
individual devices.
For each of these applications, advanced
QoS features support Internet Engineering
Task Force (IETF) standard DiffServ QoS
architecture, packet classification based on
the contents of packet header fields (voice,
video, data), traffic policing, and remote
sniffing. As a result, optimal network
performance and reliability may be attained
while realizing significant cost savings.
Customized service type and flow-based
administrations through traffic shaping and
policing may also be established, providing
an opportunity for customer-specific service
offerings, which can be implemented to
address-specific and unique customer
requirements.
Queuing function
The BayStack 460 Switch provides network
availability for mission-critical applications,
devices, and users. This is done by classifying,
prioritizing, and marking LAN IP traffic
using up to eight hardware-based IP service
class queues (on the Gigabit uplink ports)
based on the following parameters:
• ToS/DSCP marking
• IP source address/destination address
or subnets
• TCP/UDP source/destination port/
port range
• 802.1p priority bits
• Ingress source port
• IP protocol ID (e.g. TCP, UDP, IGMP)
• EtherType (e.g. IP, IPX)
• VLAN ID
It also has the ability to read packets that
have been marked from other devices such
as the Passport 8600 Switch. Also, weighted
round-robin prevents normal priority traffic
from being starved by expedited traffic (on
a per-packet basis).
Quality of Service and
policy management
QoS provides the ability to read, alter,
prioritize, and tag or mark IP traffic
based upon information imbedded in
Type of Service (ToS). Based on the IETF
Committee’s industry standards, the
BayStack 460 Switch provides the ability to
prioritize traffic based upon the required
level of service for a given transaction. This
level of service can be marked in the embedded information inside each IP packet’s ToS
field. DiffServ is based upon ToS field.
The BayStack 460 Switch has applicationspecific integrated circuits (ASICs) to
enable DiffServ Code points can be
mapped to 802.1p.
The QoS policies can be configured via the
BayStack 460 Switch built-in Web-based
management tools to facilitate QoS;
alternatively, Optivity Policy Services can be
utilized for dynamic end-to-end enterprisewide policy and QoS management, which is
facilitated through the Common Open
Policy Support (COPS) protocol (future
software release).
Quality of Service provisioning
With Optivity Policy Services (OPS), policies
can be created through a simple intuitive
drag and drop workflow. OPS is the Policy
Decision Point in a DiffServ QoS implementation. Using OPS, common policies can be
created one time and simultaneously implemented across many BayStack 460 Switches
through a single command instead of hours
of filter configuration. Policies are easily
managed and updated in the OPS GUI.
• Simple intuitive policy creation
• Re-use filter common filter sets
• Network-wide view of policies currently
being enforced
7
• Avoid QoS provisioning errors
• Centrally manage DSCP and 802.1p to
queue mapping tables
• Save time provisioning the network;
thousands of CLI or Web transactions
reduced to a few simple actions
The BayStack 460 is planned to be
supported in OPS version 3.1 (future
release).
Newer Gigabit Ethernet MDAs
The BayStack 460 Switch supports the latest
Gigabit MDAs. Each of these MDAs will
support 8 output queues and support
traffic shaping. The three MDAs are:
• BPS2000-1GT 1-port
1000BASE-TX MDA
• BPS2000-2GT 2-port
1000BASE-TX MDA
• BPS2000-2GE 2-port Small Form
Factor GBIC MDA
With the dual-port small form factor GBIC
MDA, you can plug up to two small form
factor pluggable GBICs. There are three
types of small form factor pluggable GBICs
to choose from:
• 1-port 1000BASE-SX Small Form Factor
GBIC (LC connector)
• 1-port 1000BASE-SX Small Form Factor
GBIC (MT-RJ connector)
• 1-port 1000BASE-LX Small Form Factor
GBIC (LC connector)
New CWDM small form factor pluggable
GBICs can also be used with the two-port
small form factor GBIC MDA. With
CWDM, a customer can dramatically
increase the bandwidth supported over a
single fiber. Instead of 1 Gigabit per fiber
connection with a CWDM GBIC, eight
wavelengths can be supported per fiber.
In other words, eight gigabits of traffic can
be supported across one single mode fiber.
There are eight different wavelength GBIC
options for 40 km and eight different
wavelength GBIC options for 70 km.
Traffic Policing
Traffic Policing enables provisioning of
different levels of service by limiting traffic
throughput at the ingress (incoming) port
of the BayStack 460 Switch. For example,
if a port is set to certain speeds such as
10 Mbps, all traffic under 10 Mbps on that
port will pass and traffic that exceeds 10 Mbps
on that same port is dropped. Service
providers will find this especially useful to
control bandwidth to their customers.
IP traffic shaping
IP traffic shaping offers the ability to smooth
IP classified traffic from the Gigabit uplink
ports of a single BayStack 460 Switch.
While traffic policing is needed to provide
different levels of service to data streams on
the ingress ports, traffic shaping is needed to
smooth the traffic on the uplink connection
from BayStack 460 to the network core,
yielding the most efficient bandwidth utilization. The primary customers for rate shaping
are service providers or carrier customers that
are selling Ethernet in place of traditional
Frame Relay, ISDN, or ATM WAN access
solutions, and providing end-to-end
Ethernet service for simplicity. Some
enterprise customers use traffic shaping
as a mechanism to limit bandwidth without
having to swap out physical interfaces,
leaving them room to grow.
