access. Packet filtering provides an addi-
tional means to segment and secure sensi-
tive traffic or network access. Support for
RADIUS gives customers the freedom to
use current security databases.
Altering device configurations or eaves-
dropping 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 informa-
tion. SNMPv3 provides services for
sending and receiving messages, authen-
ticating 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 applica-
tions 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.
