Router Physical Interface

Main Power Plug

Redundant Power Supply Plug

The CF card that stored the IOS image is considered an internal memory module. The reason is

the IOS image stored in the card cannot be modified or upgraded. The card itself must never be

removed from the drive. Tamper evident seal will be placed over the card in the drive.

2.3 Roles and Services

Authentication in Cisco 2811 and 2821 is role-based. There are two main roles in the router that

operators can assume: the Crypto Officer role and the User role. The administrator of the router

assumes the Crypto Officer role in order to configure and maintain the router using Crypto

Officer services, while the Users exercise only the basic User services. The module supports

RADIUS and TACACS+ for authentication. A complete description of all the management and

configuration capabilities of the router can be found in the Performing Basic System

Management manual and in the online help for the router.

2.3.1. User Services

Users enter the system by accessing the console port with a terminal program or via IPSec

protected telnet or SSH session to a LAN port. The IOS prompts the User for username and

password. If the password is correct, the User is allowed entry to the IOS executive program.

The services available to the User role consist of the following:

Status Functions

Network Functions

Terminal Functions

Directory Services

SSL-TLS/VPN

EASY VPN

2.3.2 Crypto Officer Services

During initial configuration of the router, the Crypto Officer password (the "enable" password) is

defined. A Crypto Officer can assign permission to access the Crypto Officer role to additional

accounts, thereby creating additional Crypto Officers.

The Crypto Officer role is responsible for the configuration and maintenance of the router.

The Crypto Officer services consist of the following:
