Release Notes for Cisco 7000 Family for Cisco IOS Release 12.1 T
78-10811-05
Caveats
Cisco IOS Software Product Numbering Change Announcement
Starting with releases 12.1(1) and 12.1(1)T, Cisco IOS software product numbers will be modified to
fit within an 18-character product number field.
Because a Cisco IOS software product number remains at a maximum of 18 alphanumeric characters,
the dots that provided delineation of release level have been eliminated to allow product number
expansion. This will accommodate more products and features.
From Cisco IOS software release 12.1(1) onwards, decimal points or periods or dots (“.”) in Cisco IOS
software product numbers are removed. This implementation minimizes changes and risks to customer
and partner ordering systems that are interfacing with Cisco’s ERP system.
For more information, refer to Product Bulletin 1087.
Caveats
Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most
serious caveats; severity 2 caveats are less serious.
For information on caveats in Cisco IOS Release 12.1 T, see Caveats for Cisco IOS Release 12.1 T.
All caveats in Release 12.1 are also in Release 12.1 T.
For information on caveats in Cisco IOS Release 12.1, see Caveats for Cisco IOS Release 12.1, which
lists severity 1 and 2 caveats and is located on Cisco.com and on the Documentation CD-ROM.
Note If you have an account with Cisco.com, you can use Bug Navigator II to find caveats of
any severity for any release. To reach Bug Navigator II, go to Cisco.com and click Login.
Then click Service & Support: Software Center: Cisco IOS Software: Cisco IOS Bug
Toolkit: Cisco Bug Navigator II. Another option is to go to
