communications. Network resiliency,
security of data, and application-driven
performance are the mainstays of a network
built to provide services.
Aggregating network traffic from wiring
closets and servers provides increased
network performance and aids in troubleshooting. By aggregating wiring closet
traffic into a hardware-based routing switch,
inter-network traffic can be routed at wirespeed, ensuring application response times,
required by bandwidth-sensitive applications, are met. Additionally, fewer highspeed router ports are required since
high-speed wiring closet links are consolidated before connecting to the WAN router.
Troubleshooting is made easier by providing
clear distinctions for traffic segmentation.
The Passport* 1600 is a high-performance
fixed port Layer 3 solution that provides
the resilience, performance, and security
Product Brief
Passport 1600 benefits
• Strengthens resiliency
for the network core
• Increases application
performance
• Ensures security for
discreet network traffic
As competition grows for customers in
the marketplace, enterprises are relying
on technology to help them differentiate
their business. Many of the applications
used to provide services and increase
productivity require reliable, secure
Passport 1648T
Passport 1612G and Passport 1624G
required by today’s application and
competition-driven enterprise networks.
Delivering application performance with
proven reliability allows businesses to
differentiate themselves with tools for
everything from customer service to
productivity or collaboration. Resiliency
delivers maximum availability critical for
bandwidth-sensitive and revenue-generating applications. Application performance decreases the chance that data will be
dropped when traffic load increases on the
switch. Security features provide added
protection for switch configuration data,
while packet filtering helps secure and
segment sensitive traffic or network access.

The Passport 1600 is available in three
models:
• Passport 1648T with 48 10/100 ports
plus 4 connections for small form
pluggable (SFP) GBICs
• Passport 1612G with connections
for 12 SFP GBICs
• Passport 1624G with connections
for 24 SFP GBICs
The Passport 1600 series provides a
unique fixed port routing switch solution
designed to provide the resiliency,
performance, and security required by
today’s application-driven networks.
Resiliency
The Passport 1600 Routing Switch
provides increased reliability for small
network cores. Dual redundant power
supplies ensure maximum availability of
networking hardware. Support for Split
Multi-link Trunking (SMLT)†and Multilink Trunking (MLT) provides redundant
load sharing connections to one or more
desktop switches. Resiliency is addressed
at multiple layers ensuring the highest
availability of resources and the lowest
network downtime.
Split Multi-link Trunking (SMLT) and
Multi-link Trunking (MLT)
MLT support allows up to four ports to
be grouped as a single trunk, providing
increased bandwidth and resilient connections. Combined with Nortel Networks
unique SMLT technology, switches can
be dual homed or have multiple active
connections to a network core. By
utilizing these dual connections and
bypassing traditional solutions like
Spanning Tree Protocol, customers can
increase available bandwidth and decrease
network downtime with a simple
keystroke. Customers can now increase
reliability and performance without
restructuring the network.
Performance
Application performance minimizes
packet delay and jitter when the traffic
load increases on the switch. Wire-speed
routing and Quality of Service (QoS)
mechanisms deliver the performance

Switch stack
required for applications such as IP
telephony, as well as multimedia and
collaboration applications. A non-blocking
switch fabric, together with hardware-based
routing, decrease the chance that data will
be dropped when the traffic load increases
on the switch. The policing and shaping
features†permit traffic flows to be
controlled based on applications needs.
With support for 48 10/100 ports (Passport
1648T) or up to 24 GBIC ports (Passport
1624G), application performance can be
delivered anywhere in the network.
QoS
Being able to classify, process, and expedite
traffic based on an application’s requirements are more important than ever. QoS
and the ability to prioritize traffic are what
enables a switch to support bandwidthsensitive applications. By assigning QoS
levels to traffic flows, applications can get
the bandwidth and network priority
demanded by specific applications. Four
priority queues are the basis for QoS in the
Passport 1600. Combined with wire-speed
routing and filtering, the Passport 1600’s
QoS features enable application-based
solutions to be implemented when and
where you need them most.
Routing performance
Wire-speed routing and a non-blocking
switch fabric provide the basis for a
network designed to increase collaboration
and productivity. IP telephony, Customer
Relationship Management (CRM), and
collaboration applications promise great
increases in employee productivity.
However, these applications have stringent
requirements on the network. The
Passport 1600 is designed to be able to
route, filter, and queue traffic so that no
data is lost, dropped, or delayed. Applications get the bandwidth they need, when
they need it, without delay or jitter.
Security
Security features provide added protection
for switch configuration data, while packet
filtering helps secure and segment sensitive
traffic or network access. Support for
Simple Network Management Protocol
(SNMPv3)†and Secure Shell (SSH)
†
supply protection for sensitive switch
configuration data. Multi-level access and
defined access policies help secure the
switch against unauthorized management

Simple Network Management Protocol
and Secure Shell
Altering device configurations or eavesdropping on configuration command
sessions represents real security concerns.
Switch configuration information and
its integrity are critical to maintaining a
mission-critical network. The Passport
1600 supports SNMPv3 and SSH for
controlling switch configuration information. SNMPv3 provides services for
sending and receiving messages, authenticating and encrypting messages, and
controlling access to managed objects.
SSH specifies the way to conduct secure
communications over a network. Together
these protocols help ensure that access to
critical network resources, like the
Passport 1600, is maintained.
Summary
As competition in the marketplace
intensifies, there will be more pressure for
networks to support additional applications and the ability for a network to adapt
and perform will become more critical.
Core network routing represents an area
where technology will be asked to deliver
much in the way of performance and
resiliency. The Passport 1600 Routing
Switch meets these challenges head-on by
combining resiliency, performance, and
security into a high-performance 1 U
high solution. With this addition to the
Passport LAN portfolio, Nortel Networks
continues its position as a complete
“end-to-end” enterprise solution company.
