OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S2
Conditions: This symptom is observed on Engine 3 line cards that are installed in a Cisco 12000
series that runs Cisco IOS Release 12.0(25)S1 or a later release.
Workaround: There is no workaround.
• CSCed70822
Symptoms: With four fabric cards (one CSC in slot 16 and three SFCs), after a power cycle, the line
cards fail to come up and fabric ping timeouts occur.
Conditions: This symptom is observed on a Cisco 12000 series and affects all E4 and E4+ cards.
Workaround: Place a CSC card in slot 17. The fix for this caveat applies to all types of line cards
(E0, E2, E3, E4 and E4+).
• CSCed71467
This caveat consists of two symptoms, two conditions, and two workarounds:
Symptom 1: When a policy map is applied under an L2VPN (AToM: CRoMPLS) ATM PVC on a
Cisco 12000 series Engine 3 ATM card, it is not possible to get class-map or policy-map statistics.
When you enter the show policy map interface command, the following message is seen:
Class statistics not available.
This message is seen on a policy map without policing, and in this specific case, the policy map uses
a class-default match and sets the MPLS EXP bits.
Condition 1: This problem is seen when a policy map that does not include any policing is applied
to a Cisco 12000 series Engine 3 ATM line card that is configured for AToM/L2VPN.
Workaround 1: Enable policing to get the policy-map and class-map statistics.
Symptom 2: If a policy map that involves policing is applied L2VPN (AToM: CRoMPLS) ATM PVC
on a Cisco 12000 series Engine 3 ATM card, the policy-map statistics are available but the following
incorrect message shows up at the top of the output of the show policy map interface command:
NOTE: Statistics are aggregated for all the VC’s in the subinterface
This statement is not true because the per VC policy-map statistics are available in the case of
L2VPN PVCs on this line card.
Condition 2: This problem is seen when the same policy map as in Condition 1 is modified to include
policing.
Workaround 2: There is no workaround.
• CSCed72340
Symptoms: Some MQC commands on 4xOC3 and 8xOC3 ISE line cards on Cisco 12000 series
routers may result in a message similar to the following:
% Service policy on FR sub-interface POS1/1.2 must be hierarchical.
Due to the error, no policy is applied to the interface. Even though the running configuration has the
policy on the interface, the policy will not take effect.
Conditions: This symptom is observed on Cisco 12000 series routers.
Workaround: There is no workaround.
• CSCed72686
Symptoms: An ACL applied to an ATM subinterface (RFC1483) may not work after a PRE
switchover.
Conditions: This problem is observed on a Cisco 10008 router with PRE2.
Workaround: Deconfigure and configure again the access list that is not working.
