Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(30)S
Conditions: This symptom is observed on a Cisco 12000 series that runs the gsr-p-mz image of a
Cisco IOS interim release for Release 12.0(30)S. Note, however, that this caveat is resolved in
Release 12.0(30)S.
Workaround: There is no workaround.

Symptoms: When you enter the dir command on a disk, the command fails with a “read_file/dir
failed” error message.
Conditions: This symptom is observed on a Cisco platform that runs Cisco IOS Release 12.2S.
Workaround: Format the disk. Note that the fix for this caveat involves a design change and is
therefore integrated in various releases.

Symptoms: When you first enter the aps working command and then enter the aps group
group-number command, the group-number argument is automatically set to zero. Even when you
enter the no aps group group-number command, you still can not set the group-number argument
to a value other than zero.
Conditions: This symptom observed on a Cisco 12000 series that runs an interim release for
Cisco IOS 12.0(30)S. Note, however, that this caveat is resolved in Release 12.0(30)S.
Workaround: Enter the no aps working command. Then, enter the aps group group-number
command followed by the aps working 1 command.

Symptoms: An active RP crashes after you remove an event manager applet.
Conditions: This symptom is observed on a Cisco 12000 series that runs an interim release for
Cisco IOS Release 12.0(30)S. However, this symptom is resolved in Release 12.0(30)S. The
symptom may also occur in other releases.
Workaround: There is no workaround.

Symptoms: In Cisco IOS software releases earlier than Cisco IOS Release 12.0(27)S3,
Release 12.0(28)S1, and Release 12.0(30)S, the CPU utilization of a Cisco 10720 is high (x%/y%,
where y is greater than 60 percent), and continuous BGP and LDP flapping is reported. The counters
in the output of the show interface command show a large number of drops and the output of the
show buffers command shows a large number of cache misses for the private IBC buffer pools.
Conditions: This symptom is observed when the Cisco 10720 functions in a broadcast ARP storm
environment and when the length argument of the hold queue length in interface configuration
command is not the default of 75 packets for any interface of the router (for example, the length
argument is 2048).
Workaround: Revert the hold queue length in interface configuration command and the hold queue
length out interface configuration command to the default setting on all interfaces with non-default
hold queues.
CSCef52712
Symptoms: The CPU utilization of a Cisco 12000 series may approach 100 percent when a
10,000-line IPv6 ACL is added and removed, and the router may crash.
Conditions: This symptom is observed on a Cisco 12000 series that runs an interim release for
Cisco IOS Release 12.0(30)S. Note, however, that this caveat is resolved in Release 12.0(30)S.
Workaround: There is no workaround.
