Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S1
• CSCsa59829
Symptoms: With traffic passing over a network only occasionally, a 4-port OC12 ATM ISE line card
generates a “%PM622-3-CPK24_INTR: Egr SAR timeout” error message and resets.
Conditions: This symptom is observed on a Cisco 12000 series.
Workaround: Reload the line card.
Further Problem Description: The symptom occurs when the “CPK24 FPGA” detects that the SAR
does not respond in the “Utopia interface.” The SAR then crashes because of a bad canonical header
in the egress direction.
• CSCsa60026
Symptoms: Cells loss occurs on a single ATM link of PA-A3-8T1IMA or PA-A3-8E1IMA port
adapter.
Condition: This symptom is observed on a Cisco 7500 and 7200 series when one of the T1 or E1
member interfaces of an IMA group that is configured on a PA-A3-8T1IMA or PA-A3-8E1IMA port
adapter is disconnected or when you enter the shutdown command on one of these T1 or E1 member
interfaces. The symptom is not platform-specific and may also occur in other releases.
Workaround: There is no workaround.
• CSCsa64476
Symptoms: A Cisco 10000 series generates the following error message:
%GENERAL-3-EREVENT: ACLs could not add IDB to list
The message is followed by a traceback.
This may indicate that the standby PRE does not apply the ACL for security purposes.
Conditions: This symptom is observed on a Cisco 10000 series that is configured with redundant
PREs. The symptom is a timing issue.
Workaround: There is no workaround.
• CSCsa67488
Symptoms: A Cisco 10008 router with PRE1 may report a PXF crash.
Conditions: The symptom is observed when modifying an access-list that is already attached to a
multilink interface.
Workaround: Modify an access-list only if it not attached to the interface. If the access-list cannot
be removed from the interface, then create a new one and apply.
• CSCsa74044
Symptoms: An RP crashes during large interface configuration changes when interfaces and QoS
policies are added or deleted.
Conditions: This symptom is observed on a Cisco 12000 series when the configuration changes
involve ATM and serial interfaces.
Workaround: There is no workaround.
• CSCsa77105
Symptoms: An LSP ping (or traceroute packet) is incorrectly sent from an unlabeled interface,
preventing the LSP ping to detect LSP breakages when a one-hop label switched path is pinged.
Conditions: This symptom is observed on a Cisco router that is configured for MPLS OAM.
Workaround: There is no workaround.
