2 Cisco 2811 and 2821 Routers
Branch office networking requirements are dramatically evolving, driven by web and e-
commerce applications to enhance productivity and merging the voice and data infrastructure to
reduce costs. The Cisco 2811 and 2821 routers provide a scalable, secure, manageable remote
access server that meets FIPS 140-2 Level 2 requirements. This section describes the general
features and functionality provided by the routers. The following subsections describe the
physical characteristics of the routers.
2.1 The 2811 Cryptographic Module Physical Characteristics
Figure 1 – The 2811 router case
The 2811 Router is a multiple-chip standalone cryptographic module. The router has a
processing speed of 350MHz. Depending on configuration, installed AIM-VPN/EPII-Plus
module, or the internal NetGX chip or the IOS software is used for cryptographic operations.
The cryptographic boundary of the module is the device's case. All of the functionality
discussed in this document is provided by components within this cryptographic boundary.
The interface for the router is located on the front and rear panels as shown in Figure 2 and
Figure 3, respectively.
