Release Notes for Cisco IOS Release 12.0 S
78-7130-11 Rev. B0
Caveats
• CSCdp21343
Some permanent virtual connections (PVCs) in ATM line cards do not function. The show atm vc
command indicates that the ATM PVC peak and average rates are zero. The state of any
sub-interfaces remain INACTIVE. During a reload when the shut ATM sub-interface is
encountered, all subsequent sub-interfaces within that interface will be ignored.
Workaround: Ensure that the ATM interface is not shut. Enter the shut and no shut commands on
each affected ATM sub-interface.
• CSCdp21424
Under certain conditions, a Cisco 7200 or 7500 series router with a multichannel E1/T1 port
adapter might exhibit the following error message:
%LINK-2-INTVULN: In critical region with interrupt level=0, intfc=Serial3/0:0
There is no workaround.
• CSCdp31259
Enhanced OC48 Packet-Over-SONET (POS) line cards will not boot correctly if the fabric
downloader is upgraded while running affected images. This problem can be triggered by the
following commands:
The problem causes the line card to boot incorrectly. Changing to a different version of code is
required to correctly load the card once the fabric downloader upgrade has been executed. The
upgrade will need to be reinstalled after reload.
Workaround: Do not upgrade the fabric downloader by avoiding the upgrade commands.
• CSCdp31471
The available bit rate (ABR) feature on PA-A3 does not work. The PA-A3 driver can send and
receive forward resource management (FRM) cells but backward resource management (BRM)
cells cannot be transmitted. There is no workaround.
