Chapter 1 Overview of the Routers

Secure Key

A hardware secure key storage unit is provided on the Cisco 3925 and Cisco 3945 routers to safely store
passwords and credentials. The secure key storage unit is a self-contained tamper-resistant computer
key-store that acts as a black box for credential storage by accepting credentials and never returning
them.

Cryptographic Accelerator

Cisco 3925E and Cisco 3945E ISRs ship with a Services Performance Engine that includes an onboard
cryptographic accelerator. It shares security processing for SSLVPN and IPSec. By default, acceleration
of SSL is disabled so IPSec performance is maximized.
If you want to set up the router as an SSLVPN gateway, enable the SSLVPN feature with the
crypto engine accelerator bandwidth-allocation ssl fair command. To learn more about the
cryptographic accelerator, see the Configuring the Security Features module in the Cisco 3900 series,
2900 series, and 1900 series Integrated Services Routers Software Configuration Guide at Cisco.com.

Slot, Port, and Interface Information

Table 1-11
On the Cisco 2901 router, the numbering format for slots and ports is defined as follows: interface type
0/slot/port. "0" indicates slots that are built into the chassis of a router. On the Cisco 2901 router, all
slots begin with "0," because all slots are built into the chassis. On the Cisco 2911, 2921, 2951, and Cisco
3900 series routers, some slots are built into the chassis and some are external.
Slots that are part of a network module or an extension voice module have numbers that begin with "1"
or "2," respectively. See the module documentation for more information.
