Nortel Nortel Passport 8100, Справочное руководство, Страница: 25 / 252

• Cost-effective, simpler stacking – Two built-in
stacking ports provide simpler, quicker, and more
cost-effective stacking, as expensive stacking
modules are not required. This unique stacking
design frees up both the uplink ports for dedicated
connectivity to the backbone.
• Higher uplink capacity – Two built-in GBIC ports
for dedicated uplink connectivity to network core
switches such as Passport 8600. This doubles the
uplink bandwidth, as GBIC ports are not required
for stacking purposes. Up to 16 GBIC ports are
available for pure uplink connectivity in a full
stack – the highest in the market.
• Fail-Safe Stacking – Innovative fail-safe cascade
design assures continuous uptime even if any
switch in the stack should fail and eliminates a
single point of failure.
• Resilient connectivity for minimal network
downtime – With Nortel Networks unique
Distributed MultiLink Trunking (DMLT) feature
trunked ports can span multiple units of the stack
for fail-safe connectivity to mission critical servers
and the network centre. Passport 8600’s Split
MultiLink Trunking (SMLT) eliminates single points
of failure in the network and allows BayStack 470s
to have multiple active connections to the
network core.
• Secure access and data traffic protection –
Features include BaySecure, Radius, IP Manager
List, Access List, SNMP v3, password protection and
Extensible Authentication Protocol (EAP) over LAN.
Nortel Networks is the only major vendor to
support SNMPv3 protocol for user authentication
and data encryption.
• High availability with QoS features – Provides
network availability for mission-critical
applications, devices, and users by classifying,
prioritising, and marking LAN traffic.
• Common software lowers training and
installation costs – All BayStack switches,
including the BayStack 470-48T, have a common
"look and feel" which reduces training costs. These
tools include Web, Command Line Interface (CLI),
menus, Optivity Network Management System
(NMS), Optivity Switch Manager (OSM) and
Optivity Policy Services (OPS).
• Save money and time with Auto MDI/MDIX
feature – This feature eliminates the need for
expensive cross-over cable while connecting to a
hub or switch. The switch port automatically can
detect the signal on the cable and configures itself
appropriately.
