Secure Operation of the Cisco 1721, 1760, 2621XM, 2651XM, 2691, 3725, 3745, and 7206 VXR NPE-400 Routers

Key Zeroization

All the keys and CSPs of the module can be zeroized. Please refer to the Description column of

for information on methods to zeroize each key and CSP.

Self-Tests

In order to prevent any secure data from being released, it is important to test the cryptographic

components of a security module to insure all components are functioning correctly. The router includes

an array of self-tests that are run during startup and periodically during operations. If any of the self-tests

fail, the router transitions into an error state. Within the error state, all secure data transmission is halted

and the router outputs status information indicating the failure.

Self-tests performed by the IOS image:

Routers meet all the Level 2 requirements for FIPS 140-2. Follow the setting instructions provided

below to place the module in FIPS mode. Operating these routers without maintaining the following

settings will remove the module from the FIPS approved mode of operation.
