Cisco Cisco IOS Software Release 12.2(2)XA

The 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 Release 12.2(2) XA supports the same feature sets as Cisco IOS Release 12.2(2) T, but 
Cisco IOS Release 12.2(2) XA can include new features supported by the Cisco AS3600 series.

If you have a Cisco.com login account, you can find image and release information regarding features 
prior to Cisco IOS Release 12.2(2) T by using the Feature Navigator tool at 
http://www.cisco.com/go/fn.

Cisco IOS images with strong encryption (including, but not limited to, 168-bit Triple Data 
Encryption Standard [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, purchaser and 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 export@cisco.com.
