Enterasys Networks XSR-3250 Benutzerhandbuch

ideal to support mission- critical applications extending to the branch
office.

The XSR-3250 offers nearly ten times the performance speed of the XSR-
1850 and approximately 15 times more VPN tunnels. Coupling these
features with the six network interface module (NIM) slots makes the XSR-
3250 ideally suited to a regional office required to terminate up to six
T3/E3 or 24 T1/E1 connections. A redundant power supply is included.

The features of each XSR module are summarized in

Table 1 - Features At-a-Glance

Some highlighted security features of the XSR modules are:

• Telnet over IPSec or SSHv2-secured remote management of the

modules

• Site-to-Site application VPN using IPSec

• Remote access VPN using L2TP over IPSec

• Access control through assigned privilege level

• User, certificate, and host key database files encrypted with a

master encryption key

Cryptographic Module

The XSR modules were evaluated as multi-chip standalone cryptographic
modules. The metal enclosure physically encloses the complete set of
hardware and software components, and represents the cryptographic
boundary of each module.
