Chapter 1 Overview of the Routers Slot, Port, and Interface Information 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 and Table 1-12 show slot, port, and interface numbering ranges. 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.
