Resolved Caveats—Cisco IOS Release 12.0(28)S
• CSCed33627
Symptoms: A 3-port Gigabit Ethernet (GE) line card may show an BMA error, then run error
recovery.
Conditions: This symptom is observed on a Cisco 12008/40 router that is running Cisco IOS
12.0(23)S5, that is configured as an MPLS inter-AS ASBR, and that is also configured as a PE
router. When you enter the shutdown command followed by the no shutdown command on a POS
interface of an 8-port POS line card, the 3-port GE line card shows an BMA error.
Workaround: There is no workaround.
• CSCed34184
Symptoms: After performing a manual switchover on a dual PR router in SSO mode, the following
traceback may be seen:
%SYS-3-MGDTIMER: Uninitialized timer, timer delink
In some cases, this situation may cause the RP to reload.
Conditions: This symptom is observed on a Cisco 12000 series that is running the gsr-p-mz image
of Cisco IOS Release 12.0(27)S.
Workaround: There is no workaround.
• CSCed34642
Symptoms: An Engine 4+ line card may generate errors after a router reloads.
Conditions: This symptom occurs only when the line card is switching small packets (IP length
~28 bytes).
Workaround: There is no workaround.
• CSCed34665
Symptoms: The interface protocol is down when keepalive is configured, and the speed 100
interface configuration command does no longer function.
Conditions: This symptom is observed on a Cisco 10720.
Workaround: Use the speed auto command, assuming that the connected device also supports this
command.
• CSCed35573
Symptoms: A ping does not go through for large packet sizes.
Conditions: This symptom is observed on a Cisco 12000 series router.
Workaround: There is no workaround.
• CSCed36386
Symptoms: When an interface that is configured with an IP address goes down while another
interface is configured with the same IP address, traffic destined to this IP address may not be
received by the interface that remains up.
Conditions: This symptom is observed when CEF is enabled.
Workaround: Flap the interface that is up. Doing so enables the interface to receive traffic for the IP
address.
• CSCed37615
Symptoms: A router may reload unexpectedly after renaming a policy-map the second time.
Conditions: This defect may be observed if there are at least two policies configured.
