Note
Open Caveats—Cisco IOS Release 12.1(5) XV3
There are no open caveats specific to Cisco IOS Release 12.1(5) XV3 that require documentation in the release notes.
Resolved Caveats—Cisco IOS Release 12.1(5) XV3
All the caveats listed in this section are resolved in Cisco IOS Release 12.1(5) XV3. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
•
An error can occur with management protocol processing. Please use the following URL for further information:

Open Caveats—Release 12.1(5) XV2
This section documents possible unexpected behavior by Cisco IOS Release 12.1(5) XV2 and describes only severity 1 and 2 caveats and select severity 3 caveats.
•
On a Cisco AS5800 universal access server or Cisco AS5850 universal gateway running Cisco IOS Release 12.1(5) XV2, for V.110 calls, show isdn status command in the EXEC mode displays the "calltype" field incorrectly as VOICE instead of V.110.
Workaround: Use the show spe command in EXEC mode to determine the call type for each port.
•
The configuration of the serial interfaces that correspond to the controllers on a CT3-216UP card installed in a Cisco AS5850 is lost if the card is subjected to an online insertion and removal (OIR) removal followed by an OIR insertion. The loss of the configuration causes calls to the CT3-216UP card to fail.
Workaround: Reconfigure the serial interfaces.
•
A CT3-216UP card installed in a Cisco AS5850 might reload unexpectedly during boot and then reports a bad device ID on the Fast Ethernet controller on the backplane. The CT3-216UP card subsequently boots up and functions correctly. There is no workaround.
•
If the download of nondefault universal port firmware is attempted on a CT3-216UP card in slot 0 of a Cisco AS5850 universal gateway system, one half of the ports on that card get stuck in downloading state and so become unusable.
Workaround: To recover those ports, configure the download of the IOS-bundled default firmware on them.
Under some as yet undetermined conditions, the download of the nondefault firmware can also sometimes cause the CT3-216UP card in slot 0 to crash.
Workaround: Change the configuration to cause the default IOS-bundled firmware to be downloaded to the CT3-216UP card in slot 0.
•
A Cisco AS5850 universal gateway system may suffer a system reset under stress if it has authentication, authorization, and accounting (AAA) periodic accounting configured.
Workaround: Disable AAA periodic accounting on the system.
•
On a Cisco AS5850 universal gateway, the 24 Port E1 Feature card sometimes resets under undetermined conditions.
There is no known workaround.
•
While switching IP multicast traffic, some as yet undetermined condition can sometimes cause the Cisco AS5850 universal gateway system to reset unexpectedly.
There is no known workaround.
Resolved Caveats—Release 12.1(5) XV2
All the caveats listed in this section are closed or resolved in Cisco IOS Release 12.1(5) XV2. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
•
On a Cisco AS5400 universal gateway, Cisco AS5800 universal access server, or Cisco AS5850 universal gateway running Cisco IOS Release 12.1(5)XV, data is corrupted for V.110 calls at the speeds of 12 kbps and 24 kbps. On the Cisco AS5850 and Cisco AS5400, all V.110 calls at these speeds are affected by this problem. On the Cisco AS5800, all V.110 calls at this speed to the "324 Universal Port Card" are affected by this problem. There is no workaround.
This portware caveat has been resolved.
•
On a Cisco AS5800 universal access server or Cisco AS5850 universal gateway running Cisco IOS Release 12.1(5)XV, the following MIB problems exist for V.110 calls:
–
–
–
There is no workaround.
This caveat is resolved in Cisco IOS Release 12.1(5) XV2.
•
Cisco IOS software contains a flaw that permits the successful prediction of TCP Initial Sequence Numbers.
This vulnerability is present in all released versions of Cisco IOS software running on Cisco routers and switches. It only affects the security of TCP connections that originate or terminate on the affected Cisco device itself; it does not apply to TCP traffic forwarded through the affected device in transit between two other hosts.
To remove the vulnerability, Cisco is offering free software upgrades for all affected platforms. The defect is described in caveat record CSCds04747.
Workarounds are available that limit or deny successful exploitation of the vulnerability by filtering traffic containing forged IP source addresses at the perimeter of a network or directly on individual devices.
This notice will be posted at http://www.cisco.com/warp/public/707/ios-tcp-isn-random-pub.shtml.
This caveat is resolved in Cisco IOS Release 12.1(5) XV2.
Open Caveats—Release 12.1(5) XV1
This section documents possible unexpected behavior by Cisco IOS Release 12.1(5) XV1 and describes only severity 1 and 2 caveats and select severity 3 caveats.
•
On a Cisco AS5800 universal access server or Cisco AS5850 universal gateway running Cisco IOS Release 12.1(5) XV1, for V.110 calls, the show isdn status command in EXEC mode displays the "calltype" field incorrectly as VOICE instead of V.110.
Workaround: Use the show spe command in EXEC mode to determine the call type for each port.
•
Under a rare and undetermined condition with all modems in a "busyout" state, the Cisco AS5850 reloads unexpectedly. There is no workaround.
•
The configuration of the serial interfaces that correspond to the controllers on a CT3-216UP card installed in a Cisco AS5850 is lost if the card is subjected to an OIR removal followed by an OIR insertion. The loss of the configuration causes calls to the CT3-216UP card to fail.
Workaround: Reconfigure the serial interfaces.
•
A CT3-216UP card installed in a Cisco AS5850 might reload unexpectedly during boot and then report a bad device ID on the Fast Ethernet controller on the backplane. The CT3-216UP card subsequently boots and functions correctly. There is no workaround.
Resolved Caveats—Release 12.1(5) XV1
All the caveats listed in this section are closed or resolved in Cisco IOS Release 12.1(5) XV1. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
•
On a Cisco AS5400 universal gateway, Cisco AS5800 universal access server, or Cisco AS5850 universal gateway running Cisco IOS Release 12.1(5)XV1, data is corrupted for V.110 calls at the speeds of 12 kbps and 24 kbps. On the Cisco AS5850 and Cisco AS5400, all V.110 calls at these speeds are affected by this problem. On the Cisco AS5800, all V.110 calls at these speed to the "324 Universal Port Card" are affected by this problem. There is no workaround.
This portware caveat has been resolved.
