Overview

On power up if the enabled LED is on, the ISA or the ISM is fully functional and does not require any configuration commands. However, for the ISA or the ISM to provide encryption services, you must complete the steps in the following sections:

Enabling MPPE, page 4-2(required)

Configuring IKE, page 4-3(required)

Configuring IPSec, page 4-4(required)

Creating Crypto Maps, page 4-7(required)

Optionally, you can configure Certification Authority (CA) interoperability (refer to the “Configuring Certification Authority Interoperability” chapter in the Security Configuration Guide publication).

The ISA or the ISM provides encryption services for any interface in Cisco 7100 series and Cisco 7200 series routers. If you have previously configured IPSec on the router and you install an ISA or an ISM, the ISA or the ISM automatically performs encryption services.

Note There are no interfaces to configure on the ISA or the ISM.
