Passport 8000 Family Enterprise Switch Product Brief

The Passport 8000 chassis provides 
simplified installation and maintenance,
with power supplies, fan trays and all 
system and interface modules being 
accessible from the front of the chassis.
The system supports scalable switching
bandwidth up to 128 Gbps and a wide
range of interface types, including 
Fast Ethernet, Gigabit Ethernet, Packet
over Synchronous Optical Network
(SONET), and Asynchronous Transer
Mode (ATM). Multi-Link Trunking
(MLT) provides scalable riser, server, and
inter-switch bandwidth up to 16 Gbps.
Effective control of bandwidth-hungry 
IP Multicast applications is automatically
provided using standard IETF protocols
such as Distance Vector Multicast
Routing Protocol (DVMRP) and Internet
Group Management Protocol (IGMP).
Policy services and prioritization for critical
applications are easily implemented and
monitored on the Passport 8600 using
Optivity* end-to-end policy management.
Intelligent agents in the Passport 8600
interface modules provide IEEE 802.1p
Class of Service (CoS) and IETF
Differentiated Service (DiffServ) support
to prioritize applications across the network,
with up to 8 queues per port available to
carry the different types of traffic.

Configuration and management of
Passport 8000 switches is supported by
Nortel Networks’ industry and market-
leading Optivity network management
system and a common Command Line
Interface (CLI) across the Nortel
Networks enterprise product families.
Every Passport 8000 switch port also 
supports 4 groups of Remote Monitoring
(RMON) and Conversation Steering for
use with Optivity web-enabled probes,
enabling network managers to diagnose
problems without leaving their desks.

The Passport 8000 chassis provides 
a single integrated platform to meet 
all LAN and MAN requirements.
Passport 8000 provides easy front-access 
to all system components and interface
modules, reducing floor-space requirements
in wiring closets and data centers. 
System components are common to both
6- and 10-slot chassis, and many interface
modules are shared with other Nortel
Networks switches, reducing sparing and
maintenance costs. Passport 8000 provides
scalable switching bandwidth up to 128
Gbps together with system and interface
modules for edge switching, core routing
switching, and multi-service MAN
connectivity. Network managers can
deploy Passport 8000 with the knowledge
that Nortel Networks is able to provide
unmatched technology and applications 
to reduce the total cost of ownership 
of the network.
