Objectives
This document contains instructions and procedures for installing and configuring the Integrated
Services Adapter (ISA) in Cisco 7200 series routers and the Integrated Services Module (ISM) in Cisco
7100 series routers. Also contained in this document are basic configuration steps and examples of router
commands and displays.
The ISA is a single-width service adapter and the ISM is a single-width service module. Each provides
high-performance, hardware-assisted tunneling and encryption services suitable for virtual private
network (VPN) remote access, site-to-site intranet, and extranet applications. The ISA and the ISM
offload IP Security Protocol (IPSec) and Microsoft Point to Point Encryption (MPPE) processing from
the main processor of the Cisco 7200 series or Cisco 7100 series router, thus freeing router resources for
other tasks.
Although both the ISA and the ISM provide the same functionality, they are physically unique cards
designed for different router platforms, with their own part numbers:
• SM-ISM(=)—Cisco 7100 series routers
• SA-ISA(=)—Cisco 7200 series routers
Note The information provided in this document applies to both the ISA and the ISM unless specifically stated
otherwise.
