Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S4
Conditions: This symptom is observed on a Cisco 12000 series that runs the boot loader image of
Cisco IOS Release 12.0(30)S.
Workaround: There is no workaround.
• CSCeg82322
Symptoms: Platform independent multicast protocol software running in a line card will exit without
logging any errors when detecting an illegal value for an input “hardware” interface if_index or an
input “software” interface if_number.
A line card may crash or experience other errors whose cause will be difficult to identify.
Conditions: These symptoms only occur when a preceding error has occurred during route processor
assignment of interface indices. These errors are frequently accompanied by error messages.
Workaround: Utilize RP error messages if available to diagnose the cause of the problem.
• CSCeh04295
Symptoms: When ATM packets are sent over an 8-port OC-3 ATM Engine 2 line card, the packets
are punted to the CPU of the line card, causing traffic drops.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(31)S and that is configured for AToM when an 8-port OC-3 ATM Engine 2 line card
is the disposition card.
Workaround: There is no workaround.
• CSCeh13340
Symptoms: On a Cisco XR 12000 series hardware-based forwarding line card, the receive counters
in the output of the show mpls l2transport vc command do not work in any images for AToM.
Conditions: This symptom is observed on all hardware-based engine line cards on a Cisco XR 12000
series that is configured for AToM and Sampled NetFlow on the core-facing line cards.
Workaround: There is no workaround.
• CSCeh13919
Symptoms: A Cisco 12000 series line card may generate the following error message and traceback
when you delete MLP bundles:
%LC_DMLP-4-BUNDLENULL: Unexpected null bundle in bflc_cx3_dmlp_frag_on_off, searching
for group13
-Traceback= 402FFF44 40300228 40E1880C 40E18BE0 40E19900
Conditions: This symptom is observed on a Cisco 12000 series when you delete MLP bundles by
entering the copy tftp run command to copy the configuration script that is supposed to delete the
MLP bundles.
Workaround: There is no workaround. However, the message does not impact any functionality of
the router and the router recovers by itself.
• CSCeh14012
Symptoms: A 1-port channelized OC-12/STM-4 (DS1/E1) ISE line card on a CE router may crash
when many (168) MLP interfaces are deleted and reconfigured via TFTP on a directly-connected PE
router.
Conditions: This symptom is observed on a Cisco 1200 series that functions as a CE router.
Workaround: There is no workaround.
