Early Deployment Releases

Cisco IOS Release 12.1E supports the Catalyst 6500 series MSFC router daughter card, the FlexWAN module, and the Optical Services Modules (OSMs) listed in the "Supported Hardware" section.

Release 12.1E is an early deployment (ED) release based on Release 12.1. All features and functionality in Release 12.1(26) and in earlier 12.1E releases are in Release 12.1(26)E6.

For information on earlier releases, refer to this publication on Cisco.com at this URL:

http://www.cisco.com/en/US/products/hw/switches/ps708/prod_release_notes_list.html

For more information about the Cisco IOS software release process, refer to Cisco IOS Software Releases: Product Bulletin 537 located on Cisco.com:

http://www.cisco.com/warp/public/cc/pd/iosw/iore/prodlit/537_pp.htm

These release notes do not describe features that are available in Release 12.1, Release 12.1 T, or other Release 12.1ED releases.

All caveats resolved in Release 12.1(26) and earlier 12.1E releases are also resolved in Release 12.1(26)E6. For a list of the caveats that apply to Release 12.1(26)E6, see the "Caveats" section and refer to the Caveats for Cisco IOS Release 12.1 publication at this URL:

http://www.cisco.com/en/US/docs/ios/12_1/relnotes/crossplatform/release/notes/121mcavs.html
