Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S4
Workaround: Do not delete and re-add the same subinterface. Rather, enter the shutdown command
followed by the no shutdown command to achieve the same effect.
• CSCeh60368
Symptoms: On a Cisco 10000 series that is configured with 6-port channelized T3 line cards, when
the primary and standby PREs are each loaded with a different Cisco IOS software release (for
example, Release 12.0(28)S and Release 12.0(28)S3) and when the standby PRE boots, the standby
PRE may crash or other errors may occur while the standby PRE configures the channelized T3
channels.
Conditions: This symptom is observed on a Cisco 10000 series for Cisco IOS Release 12.0(27)S,
Release 12.0(28)S, Release 12.0(30)S, Release 12.0(31)S or a rebuild of these releases when the
standby PRE runs a Cisco IOS software release that is either older or newer than the software release
on the primary PRE and when one PRE runs a software release that includes the fix for caveat
CSCsa41907 and the other PRE runs a software release that does not contain the fix for caveat
CSCsa41907.
Workaround: Do not perform live software upgrades. Rather, bring the primary PRE down and boot
the standby PRE with the same Cisco IOS software release that runs on the primary PRE, so that
when both PREs come up, their software releases match.
Further Problem Description: When both the primary and standby PRE run a Cisco IOS software
release that contains the fix for caveat CSCsa41907, the symptom does not occur.
• CSCeh64632
Symptoms: After a route processor or line card has reloaded, the queue limit that is set for the class
default is not properly programmed.
Conditions: This symptom is observed on a Cisco 12000 series 1-port channelized OC-12/STM-4
(DS1/E1) ISE line card that has an egress policy applied to a serial interface.
Workaround: There is no workaround.
• CSCeh65748
Symptoms: A Engine 3 ISE line card may not properly handle incoming bad IP packets but may
generate a traceback and a transient error message:
%GSR-3-INTPROC: Process Traceback= 400E10B4 400FBA2C
-Traceback= 4047917C 405E5274 400F4B58
%EE48-3-BM_ERRS: FrFab BM SOP error 40000
%EE48-3-BM_ERR_DECODE: FrFab SOP macsopi_bhdr_pkt_len_zero_err
%GSR-3-INTPROC: Process Traceback= 400E1090 400FBA2C
-Traceback= 4047917C 405E5274 400F4B58
%LC-4-ERRRECOVER: Corrected a transient error on line card.
The line card may also crash.
Conditions: These symptoms are observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(26)S1 or Release 12.0(26)S5a.
Workaround: There is no workaround.
• CSCeh76523
Symptoms: On a Cisco 12000 series with an unidirectional MR-APS configuration, traffic los occurs
when the line card that contains the APS protect interface is reloaded.
Conditions: This symptom is observed mostly in highly-scaled APS configurations on a channelized
OC-48 ISE line card that is configured for unidirectional APS.
Workaround: There is no workaround.
