78-10811-05
Important Notes
Important Notes
The following sections contain important notes about Cisco IOS Release 12.1 T that apply to
Cisco 7000 family routers.
Image Deferral, Cisco IOS Release 12.1(5)T1
All Cisco 7200 series and Cisco 7500 series images in Cisco IOS Release 12.1(5)T have been deferred
to Cisco IOS Release 12.1(5)T1 due to the following caveats:
• CSCds35103—ATM-PA3 ucode not working with peer PA3s having very old ucode
• CSCds39413—%TCP-6-NOBUFF: TTY0, no buffer available message
• CSCds62602—VIP2-40 still not seen even after rommon upgrade to Version 122.0
• CSCds69801—NPE-400: Could not load 121-5.T image, BUS error received
Note Disclaimer: In order to increase network availability, Cisco recommends that you upgrade
affected IOS images with the suggested replacement software images. Cisco will
discontinue manufacturing shipment of affected IOS images. Any pending order will be
substituted by the replacement software images. PLEASE BE AWARE THAT FAILURE
TO UPGRADE THE AFFECTED IOS IMAGES MAY RESULT IN NETWORK
DOWNTIME. The terms and conditions that governed your rights and obligations and
those of Cisco, with respect to the deferred images will apply to the replacement images.
RSP-based MQC
As of Cisco IOS Release 12.1(5)T, RSP-based MQC features will no longer be supported and will be
replaced by VIP-based MQC features.
See CSCds82672 in the Caveats for Cisco IOS Release 12.1 T. for more information.
