Software fixes of Cisco IOS 12.1(2.4) interim build are not integrated in 12.1(3) mainline.
Other Cisco IOS Releases are not affected.
Cisco IOS Software 12.1(3) maintenance release does not include the 12.1(2.4) integrated software repairs.
Cisco IOS upgrade planning for 12.1(3) should not include any software repairs that were integrated in 12.1(2.4)
Other present releases that build from Cisco IOS Software Release 12.1, the parent, include the software repairs integrated in 12.1(2.4) in its third maintenance release, as expected: Cisco IOS 12.1DA, 12.1E, 12.1EC, and 12.1T.
Cisco will defer all IOS Software Release 12.1(2.4) images to avoid regression issues with customers. Defect fixes integrated in 12.1(2.4) will be forwarded to 12.1(3.1) and beyond.
