Module Interfaces - Cisco 2621XM Operations

2621XM and 2651XM 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 Cisco 2621XM and 2651XM routers.

The 2621XM and 2651XM Routers are multiple-chip standalone cryptographic modules. The
cryptographic boundary is defined as encompassing the "top," "front," "left," "right," and "bottom"
surfaces of the case; all portions of the "backplane" of the case which are not designed to accommodate
a WIC or Network Module; and the inverse of the three-dimensional space within the case that would be
occupied by an installed WIC or Network Module. The cryptographic boundary includes the connection
apparatus between the WIC or Network Module and the motherboard/daughterboard that hosts the WIC
or Network Module, but the boundary does not include the WIC or Network Module itself. In other
words, the cryptographic boundary encompasses all hardware components within the case of the device
except any installed modular WICs or Network Modules. All of the functionality discussed in this
document is provided by components within this cryptographic boundary.
The Cisco 2621XM and 2651XM routers incorporate an AIM-VPN/EP cryptographic accelerator card.
The AIM-VPN/EP is located inside the module chassis, and is installed directly on the motherboard.
Cisco IOS features such as tunneling, data encryption, and termination of Remote Access WANs via
IPSec, Layer 2 Forwarding (L2F) and Layer 2 Tunneling Protocols (L2TP) make the Cisco 2600 an ideal
platform for building virtual private networks or outsourced dial solutions. Cisco 2600`s RISC-based
processor provides the power needed for the dynamic requirements of the remote branch office,
achieving wire speed Ethernet to Ethernet routing with up to 30 thousand packets per second (Kpps)
throughput capacity for the 2621XM, and 40 Kpps for the 2651XM.
