• CSCed94042
Symptoms: A transient error may occur on a Cisco 12000 series line card during a network routing
change. here is a chance that other line cards in the system will stop transmitting or receiving routing
protocol updates and traffic, causing traffic to be blackholed.
Conditions: This symptom is observed in an MPLS-VPN network. A list of the affected releases can
be found at http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCeb58214.
Cisco IOS software releases that are not listed in the “First Fixed-in Version” field at this location
are not affected.
Workaround: Enter the microcode reload command on any line card that stops receiving traffic or
routing protocol adjacencies from its neighbors.
• CSCee00516
Symptoms: An echo reply source address may be set incorrectly as 0.0.0.0 when responding to an
echo request received on an unnumbered interface. Some line cards may check for the 0.0.0.0 source
address condition and discard the packet based on that condition.
Conditions: This symptom is observed during an LSP ping/traceroute. The symptom is platform
independent.
Workaround: Avoid using numbered interfaces. If this is not an option, there is no workaround.
• CSCee01931
Symptoms: A router may crash when you enter the fair-queue command on the interface of a
PA-MC-STM-1 port adapter.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0 S when
the interface has the rate-limit output command enabled.
Workaround: There is no workaround.
• CSCee02510
Symptoms: High CPU utilization may occur on a Cisco 12000 series line cards due to the CEF
scanner process.
Conditions: This problem is seen when a large number of VPN routes are present on the router.
Workaround: There is no workaround. However, the symptom does not seem to affect the
convergence time or performance of the router.
