Cisco Cisco IOS Software Release 12.4(22)XR

Cisco IOS software is packaged in feature sets consisting of software images—depending on the 
platform. Each feature set contains a specific set of Cisco IOS features.

Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption 
feature sets) are subject to United States government export controls and have limited distribution. 
Strong encryption images to be installed outside the United States are likely to require an export license. 
Customer orders may be denied or subject to delay because of United States government regulations. 
When applicable, the purchaser or user must obtain local import and use authorizations for all encryption 
strengths. Please contact your sales representative or distributor for more information, or send an e-mail 
to
