T

he way in which businesses use LANs is changing and the performance requirement at the

edge of the network is becoming more demanding. IP Telephony and other collaborative
applications are driving more traffic to the edge of the network. As file sizes continue to grow,
users need more bandwidth. Quite simply, the convergence of voice, video, data, and storage
enables users to do more from their desktop. Enterprises need to be able to address today’s
increased demands and still prepare for the unknown demands of tomorrow. By re-assessing
how they’re using the wiring closet, they can achieve both goals, and be assured that their
investments will be protected for a long time to come.

Part of the Nortel Networks BayStack* 5000 series, BayStack 5510 Switches are 1 rack unit high
stackable 10/100/1000 Mbps Ethernet Layer 3 routing switches that are designed to provide
high-density Gigabit desktop connectivity for mid-size and large enterprise customers’ wiring
closets. BayStack 5510 Switches offer a scalable and resilient solution, providing exceptional
security features and support for enhanced convergence while minimizing capital and opera-

tional expenses. The BayStack 5000 family
of switches represents the next generation in
innovation and performance in a stackable
solution.

BayStack 5510 Switches are available in
two models—the BayStack 5510-48T
Switch (Figure 1) and the BayStack 5510-24T
Switch. Power over Ethernet versions of the
switches are planned for release in the future.

Highest-density Gigabit desktop switching

The BayStack 5510-48T Switch features 48 10/100/1000BASE-T RJ-45 ports for desktop
switching and two built-in SFP (Small Form factor Pluggable) GBIC ports for uplink. Port 47
and Port 48 offer configuration flexibility by allowing the network administrator to configure
each port as either 10/100/1000 or make use of the built-in SFP GBIC. As many as eight
BayStack 5510-48T Switches can be stacked to achieve up to 384 10/100/1000 ports for
highest-density desktop switching.

The BayStack 5510-24T Switch offers 24 10/100/1000BASE-T RJ-45 ports for desktop
switching and two built-in GBIC ports for uplink. Port 23 and Port 24 offer configuration
flexibility as either a 10/100/1000 or a built-in SFP GBIC port. Both BayStack 5510-24T and
5510-48T switches may be combined in a single stack for maximum flexibility.

Innovative FAST stacking design

Nortel Networks innovative FAST (Flexible Advanced Stacking Technology) stacking design
of the BayStack 5510 allows for simultaneous bi-directional traffic flow on each stacking port
(Figure 2).In a full stack, this design yields up to 640 Gbps—the highest stacking bandwidth
in the industry today.

Switch fabric architecture offering non-blocking wire-speed performance

The BayStack 5510 Switches have a high-performance Layer 3 switching fabric with a
maximum of 160 Gbps forwarding bandwidth and wire-speed performance. The forwarding rate
for the BayStack 5510-48T is 71.4 Mpps (million packets per second) and for the BayStack
5510-24T is 35.7 Mpps

Layer 3 IP routing

The BayStack 5510 Switch architecture supports wire-speed Layer 3 IP routing across the
stack with static and local route support.

The BayStack 5510 switches support high-performance wire-speed IP routing between
VLANs. IP routing with static routes at the edge improves the network performance as the
packets do not have to go to the core and the routing takes place within the switch or stack.

The BayStack 5510 Switches support the DHCP (Dynamic Host Configuration Protocol)
Relay feature that provides the system with the ability to relay DHCP requests to the DHCP
server and eliminates the need for a DHCP server on every subnet. It forwards a request for
an IP address from a client to a DHCP server across subnets.

Software feature enhancements are planned to include support for routing protocols such as
Routing Information Protocol (RIP v1/v2)†.

Compact form factor

The BayStack 5510 Switches are offered in a
compact one-rack unit high design. An eight
unit stack provides up to 384 10/100/1000
ports. This allows for significant space and
cost savings in the wiring closet.

Unit replacement feature

In the unlikely event that a switch fails in a
stack, the affected switch can easily be
replaced without disrupting the stack.
Using the unit replacement feature, the
configuration of the failed switch may be
copied from a server to the new switch. The
switch can then be put back in the stack and
the stack is rebuilt automatically without
service interruption.

Up to 16 built-in GBIC ports in a stack

BayStack 5510 Switches have two built-in
SFP GBIC ports for dedicated uplink
connectivity to network core switches such as
the Passport* 8600. This doubles the uplink
bandwidth as GBIC ports are not required

As shown here, a unit
can simultaneously

Nortel Networks unique FAST stack-

ing design supports an optimal data

flow across the stack using a shortest

path algorithm.

Most vendors today employ a traditional

ring architecture, meaning that a packet

travels on the ring in only one direction. For

example, in a stack of eight switches, if a

packet needs to go from unit 2 to unit 3,

it can get there in a single hop. But if a

packet needs to go from unit 3 to unit 2,

then it has to traverse from 3 to 4, 4 to 5,

5 to 6, and so on until it reaches unit 2.

This requires seven hops.

Nortel Networks FAST stack design uses

the shortest past algorithm, which means

that the packet would traverse directly

from unit 3 to unit 2 in a single hop.

for stacking purposes. Using the proven Distributed Multi-Link Trunking (DMLT)
resiliency feature, up to 16 GBIC ports are available for pure uplink connectivity in a full
stack—among the highest in the market.

BayStack 5510 Switches have also been architected to support future technologies such as
10 Gigabit uplinks.

Plug-and-play stacking with built-in stacking ports

BayStack 5510 Switches have built-in stacking ports for faster, plug-and-play stacking. This
is more cost-effective as cascade modules are not required. This stacking design frees up both
of the uplink ports for dedicated connectivity to the backbone. For ordering convenience,
BayStack 5510 Switches are available in models with or without a cascade cable (1.5 foot). In
addition, cascade cables are also available in different lengths—1.5 foot, 10 feet and 5 meters
(16.4 feet)—to cover a variety of stacking needs.

Recessed stacking connectors for
higher reliability

BayStack 5510 Switches are designed with
recessed stacking connectors that save
premium closet space and protect the
integrity of the stack from accidental contact

.

BoSS (BayStack operating system
Switching Software)

BoSS for BayStack 5510 Switches is a
single software image that allows BayStack
5510-48T, BayStack 5510-24T, and future
BayStack 5000 series switches to stack
together. BoSS for BayStack 5510 Switches
is specific to this next generation of stack­ing switches, with a software image that
supports this new architecture. Earlier
BayStack switches support a different
version of BoSS—although all share the
same core software.

Simplified network operations

BoSS simplifies network operations by reducing the number of steps required for switch soft­ware updates. With BoSS, only a single image needs to be downloaded from Nortel
Networks support site for all BayStack 5510 Switch types. Loading the image to different
switches is also considerably simplified. The image is loaded only to the base unit of the stack
which automatically loads it to other switches in the stack.

BoSS v4.0 features

Newly released BoSS version 4.0 is downloadable from the Web for free and includes support
for the following new features:

• IP routing with static routes, ARP, and DHCP relay

•Security features including Secure Shell Protocol (SSHv2) and Secure Sockets Layer
(SSL) for the Web Management interface (HTTPS)

•Generation of ASCII configuration files

•QoS Queue-Set and Buffering configuration

•Custom autonegotiation advertisements

•Optivity* Policy Services

Multi-Link Trunking

Multi-Link Trunking (MLT) enables group­ing of links between the BayStack 5510 and
another switch or server to provide greater
bandwidth with active redundant links.
Nortel Networks unique Distributed Multi­Link Trunking (DMLT) feature allows
trunked ports to span multiple units of the
stack for fail-safe connectivity to mission­critical servers and the network center (Figure

4).BayStack 5510 Switches have been archi­tected to support up to 32 trunks per switch
or stack, with each trunk consisting of up to
eight members per trunk. Each trunk can
provide bandwidth of up to 16 Gbps.

The Split Multi-Link Trunking (SMLT)
feature of Passport 8600 eliminates single
points of failure in the network and allows
wiring closet switches, such as the BayStack
5510, to have multiple active connections
to the network core (Figure 5). All links from
a distributed multi-link trunk can be active
simultaneously. This allows customers to
load-balance their network, double the band­width, and use all the ports they have paid for.

By combining the reliability of the Passport
8600 with the BayStack 5510’s resilient
trunking features—including DMLT, MLT,
and bi-directional FAST stacking, Nortel
Networks has created the next generation of
flexible networking solutions. BayStack 5510
Switches are architected to support SMLT
and Inter Switch Trunk (IST) in the future.

Integrated Time Domain Reflectometer (TDR)

†

For advanced resiliency, the BayStack 5510 is architected to include an integrated TDR. This
feature will simplify troubleshooting of the physical cable plant, enabling IT managers to
quickly identify the failing mechanism and isolate to the source of the problem, helping
ensure maximum uptime of the network. Through remote and non-invasive diagnosis of
cabling issues such as cable opens, cable shorts or impedance mismatch in the cable and
report, within one meter, the distance of the fault. The switch can detect and report these
issues without unplugging cables and plugging in expensive cable testers. (Feature supported
with future software release.)

Redundant power and UPS support

With connectivity to the BayStack 10 Power Supply Unit (PSU) paired with a –48V DC-to­DC converter module, BayStack 5510 Switches deliver redundant power supply (RPS)
support crucial in mission-critical environments. Nortel Networks 800-watt BayStack 10
Power Supply Unit allows up to four failed network devices to simultaneously receive RPS
support. In addition to the RPSU support, Uninterruptible Power Supply (UPS) capability is
provided cost-effectively in the same BayStack 10 chassis.

IPv6 filtering and classification support for future applications

BayStack 5510 Switches are able to identify, prioritize, classify, and redirect IPv6 traffic to a
router. These switches can address the need for larger addressing and tighter security as the
networks grow.

Jumbo frame support for larger file applications

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.

Quality of Service (QoS)

The QoS features of the BayStack 5510 Switch allow users to not only utilize bandwidth
more efficiently, optimizing existing network resources and capabilities, but also provide
packet classification and marking at the edge of the network, simplifying the QoS deploy­ment at the aggregation and core of the network. By classifying, prioritizing, policing, and
marking LAN traffic (based on DiffServ, Code Point, and 802.1p), networks can offer reliable
connectivity and required bandwidth for mission-critical applications, such as IP Telephony, to
specific groups, users, and individual devices.

For each of these applications, advanced QoS features support Internet Engineering Task
Force (IETF), the standard DiffServ QoS architecture—a packet classification based on the
content of IP packet header fields (voice, video, data)—as well as traffic policing.

QoS and policy management

DiffServ QoS enables networks to read, alter, prioritize, tag, or mark IP packets based upon
information embedded in the Type of Service (ToS) field. The level of service can be marked
in the embedded information inside the ToS field of each IP packet. DiffServ is based on the
ToS field. BayStack 5510 Switches have application-specific integrated circuits (ASICs) to
enable the DiffServ Code Point (DSCP) to be mapped to the IEEE 802.1p user priority bits
to provide consistent QoS at Layer 3 (IP) and Layer 2 (Ethernet). The QoS policies can be
configured via the BayStack 5510 Switch’s built-in Web-based management tools to facilitate
QoS. Alternatively, Optivity Policy Services can be utilized for dynamic end-to-end enter­prise-wide policy and QoS management.

Simplified QoS

BayStack 5510 Switches support Nortel Networks Service Classes (NNSC) which provide
simplified QoS provisioning. NNSC provides factory-default QoS configurations, eliminating
the complexities often associated with QoS-enabled network deployments.

NNSC provides default settings such as:

• DSCP marking per class

•DiffServ forwarding behavior (PHB) per class

• DSCP to queue mapping

• DSCP to 802.1p mapping

•Default scheduler per class

By classifying the traffic and placing it into an NNSC, complex QoS configurations are elim­inated. NNSC simplifies the deployment of a QoS-enabled network with Nortel Networks
switching solutions, using a Web-based interface. This not only saves on provisioning time
but most importantly, ensures that the QoS functions are provisioned consistently across the
network.

Queuing function

BayStack 5510 Switches provide network availability for mission-critical applications, devices, and
users by classifying, prioritizing, and marking LAN IP traffic using up to eight hardware-based
queues on every port including the stacking ports. This is based on the following parameters:

•MAC address-based filtering

•IP ToS/DSCP marking

• IP source address/destination address or subnets

•TCP/UDP source/destination port/port range

•IEEE 802.1p user priority bits

•Ingress source port

• IP Protocol ID (e.g., TCP, UDP, IGMP)

•EtherType (e.g., IP, IPX)

• IEEE 802.1Q VLAN ID

BayStack 5510 Switches also have the ability to read packets that have been marked from
other devices such as the Passport 8600 Switch. Additionally, weighted round robin prevents
normal priority traffic from being starved by expedited traffic (on a per-packet basis).
BayStack 5510 also supports strict priority queuing.

Quality of Service provisioning

With Optivity Policy Services software, policies can be created through a simple and intu­itive drag-and-drop workflow. Optivity Policy Services is the Policy Decision Point in a
DiffServ QoS implementation.

Further benefits include:

•Simple intuitive policy creation

•Ability to re-use common filter sets

•Provision of a network-wide view of policies currently in use

7

•Ability to avoid QoS provisioning errors

• Centrally managed DSCP and 802.1p queue mapping tables

•Saved time in provisioning the network—as thousands of CLI or Web transactions are
reduced to a few simple actions

Traffic policing

Traffic policing enables provisioning of different levels of service by limiting traffic through­put at the ingress (incoming) port of the BayStack 5510 Switch. For example, if a port is set
to a certain speed, 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. Up to 64 traffic meters per port are provided
and yield higher resolution for control.

Traffic shaping

†

Traffic shaping offers the ability to limit traffic on each port. 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 from the egress ports. BayStack 5510 supports port-based traffic
shaping. Enterprises working with service providers or carriers utilize this feature when they
are deploying Ethernet in place of the traditional Frame Relay, ISDN, or ATM WAN access
solutions.

Enhanced security

The BayStack 5510 Switches offer the highest level of security with features including Secure
Shell (SSH), Secure Sockets Layer (SSL), IEEE 802.1x based security (also known as
Extensible Authentication Protocol (EAP)), assignment of proper VLAN and priority, user­based policies†, Simple Network Management Protocol (SNMPv3), IP Manager List, MAC­address-based security, and Remote Authentication Dial-In User Service (RADIUS)
authentication.

SSHv2 supports strong authentication and encrypted communications. It allows network
administrators to log into the switch from an SSH client and perform a secure Telnet session
using CLI commands. This feature is ideal for security conscious customers, such as federal
governments. SSL provides a secure Web management interface and makes it easy for the
network administrator to configure and manage a switch using a common Web browser.

For added security, BayStack 5510 Switches support the 802.1x-based security feature. The
IEEE 802.1x-based security feature limits access to the network based on user credentials. A
user is required to “login” to the network using a username/password; the user database is
maintained on the authentication server (not the switch). Network connectivity without
password authorization is prevented. This feature is useful where the network is not 100
percent physically secure or where physical security needs enhancement; for example, banks,
trading rooms, or classroom training facilities. This feature supports client access to the network
and interoperates with Microsoft Windows XP and other compliant 802.1x clients. 802.1x is
also known as Extensible Authentication Protocol (EAP).

SNMPv3 provides user authentication and data encryption for higher security. It also offers
secure configuration and monitoring.

IP Manager List limits access to the management features of the BayStack 5510 Switches by a
defined list of IP addresses or IP address ranges/subnets, providing greater network security
and manageability.

BaySecure* MAC address-based security 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 (up to a maximum of 448). In addi­tion, with the Distributed Access List Security feature, network access is granted or denied on
a per-port basis. BayStack 5510 Switches also provide RADIUS authentication for switch secu­rity management.

The convergence of

voice, video, data, and

storage enables users

to do more from their

desktop.

Fail-safe stacking

A key differentiator for BayStack 5510 Switches is their resilient stacking feature. BayStack
5510 Switches can stack up to eight units with a cascade stacking design, assuring continuous
uptime even if a single switch in the stack should fail. A loop-back or cascade cable is used to
seamlessly connect the entire stack to provide no single point of failure.

In the unlikely event of a switch failure, traffic performance is maintained at 40 Gbps on the
immediate units on either direction of the failed unit via a ‘wrapping’ method; the remaining
units in the stack continue to send traffic bi-directionally at full bandwidth capability of 80
Gbps per switch .

MAC addresses

BayStack 5510 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,
this permits scalability to be achieved in a cost-effective manner.

VLAN support

VLANs can be established for each switch to extend the broadcast domain and segment
network traffic. These VLANs can be spread among port-based or protocol-based VLANs.The
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 localize broadcast traffic and assure that the specified protocol type
packets are sent only to the protocol-based VLAN ports. The BayStack 5510 Switches have
been architected to support up to 4,000 VLANs. BayStack 5510 Switches also support per
VLAN Tagging option on each port.

IGMP snooping

BayStack 5510 Switches feature IP Multicast support by examining (‘snooping’) all Internet
Group Multicast Protocol (IGMP) traffic in hardware at line rate, and pruning unwanted
data streams from affecting network or end-station performance. Up to 256 IGMP groups
are supported.

Multiple Spanning Tree protocol groups

BayStack 5510 Switches support multiple Spanning Tree Groups (STGs), either in a single
standalone switch or distributed across a stack. STGs provide multiple data paths which can be
used for load-balancing and redundancy. The BayStack 5510 Switches have been architected to
support up to 256 STGs. The switch architecture also supports IEEE 802.1s and 802.1w†.

Nortel Networks Command Line Interface (NNCLI)

The NNCLI is used to automate general management and configuration of BayStack 5510
Switches. The NNCLI is used through a Telnet session or through the serial port on the console.

ASCII configuration files

BayStack 5510 Switches can download a user-editable ASCII configuration file from a TFTP
(Trivial File Transfer Protocol) 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 NNCLI commands in the file. This feature provides administrators with the flexibility of
creating command configuration files that can be used on several switches or stacks with minor
modifications.

The configuration settings of the switch can 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. The ASCII configuration
file contains configuration settings for the following network management applications:

• Core applications (system information, topology, etc.)

•Internet Protocol

•Multi-Link Trunking (MLT)

9

•Port configuration

•Partial Spanning Tree configuration, including configuration of port priority and path cost

•VLAN configuration

•Quality of Service (QoS)

• RMON

Custom Auto-negotiation Advertisements

This feature enables the network manager to tune the capabilities that a particular Ethernet
port can advertise via auto-negotiation. The capabilities include half-duplex and full-duplex
modes with speeds of 10, 100, and 1000 Mbps. Auto-negotiated Ethernet ports establish a
connection based upon the highest common capabilities. This feature saves the network
manager from having to go to each workstation and switch to configure a “fixed” speed.

Customizable Queue/Buffer Allocation

Using this feature, the network administrator is able to specify the number of CoS queues
supported and the buffering resources that may be consumed by a given port. It allows the
network administrator to tune the use of system resources based upon their business needs.

Auto MDI/MDIX

BayStack 5510 Switches can be connected to a hub, computer, or another switch quickly and
cost-effectively with either a crossover or straight through cable. When a cable is connected
to one of the 10/100/1000 ports on the switch, the switch port automatically detects the
energy on the cable and configures itself. This feature eliminates the need for an MDI/MDIX
port; any port may be used for connection to a hub or switch.

Common look and feel

All BayStack switches, including the BayStack 5510, 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, Java™-based Device Manager (JDM),
Command Line Interface (CLI), menus, Optivity Network Management System (ONMS),
Optivity Switch Manager (OSM), and Optivity Policy Services (OPS).

Web-based management

Web-based network management makes managing the BayStack 5510 Switch stack easy with
a Web browser. Summary, configuration, fault, statistics, application, administration, and
support pages can be provided for the 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 statistical information for stacked units. The Web interface also
allows for static configuration of numerous parameters of the device.

Network management

On-box management

Network management begins with the device. BayStack 5510 Switches support four groups
of Remote Monitoring (RMON) on all ports and are SNMPv3 compliant. RMON2
support is achievable via port mirroring and the use of an external probe. The SNMP agent
software resides in the switch and uses the information it collects to provide management for
all ports in the stack providing comprehensive network monitoring capabilities.

Configuration management

The process of configuration begins with a single device but finishes across multiple devices.
Java Device Manager is the device configuration tool for those functions that require commu­nicating with a single device. It 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) is
another tool that performs the configuration functions such as VLAN assignments, MLT,
and Multicast across multiple Nortel Networks Ethernet switches.

Policy-management

Optivity Policy Services—a suite of policy-management software that enforces business-level
policies automatically across the network now supports BayStack 5510 Switches. OPS
supports network managers by providing centralized control of advanced packet classification
and the ability to priority mark, police, meter, or block traffic.

Fault management and resolution

With Optivity Network Management System (ONMS), the network manager has quick
access to the information required to manage and isolate all network events on BayStack 5510
switches. Tools, such as Physical Topology View, inform the network manager how a particular
event is affecting the physical connectivity within the network. The ‘End Node Locate’ tool
provides the ability to locate a failing end node and, with one mouse click, provide 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 5510 Switches support “syslog” capability
that helps in troubleshooting network issues.

Port mirroring

The port mirroring feature (sometimes referred to as ‘conversation steering’) allows the
network administrator to designate a single switch port as a traffic monitor for a specified
port. Port-based monitoring can be specified for ingress and egress at a specific port. MAC
address-based mirroring can also be specified. Additionally, an external probe device can be
attached to the designated monitor port.

User Interface push-button

The User Interface push-button on the front panel is provided for ease of use in configuring
the unit. It can be used for the purpose of base unit selection and for resetting the unit or the
stack.

LED indicators

The LED indicators on the front panel make it easy to monitor the switch status and help in
isolating and diagnosing switch problems. These indicators include “Power,” “Base unit,” “Up”
and “Down,” “RPSU,” “Speed/Duplex,” and “LNK/ACT” functions.
