Resolved Caveats—Cisco IOS Release 12.0(27)S
• CSCeb58316
Symptoms: Multiprotocol Label Switching (MPLS) traffic engineering (TE) interarea and
interautonomous system tunnels may fail to reoptimize.
Conditions: This symptom is observed when a better path becomes available at a node or link beyond
the area or interautonomous system of the tunnel headend.
Workaround: There is no workaround.
• CSCeb59165
Symptoms: A standby card may not be able to switch to the active state.
Conditions: This symptom is observed in a Redundancy Framework (RF) environment when ATM,
High-Level Data Link Control (HDLC), or Frame Relay clients synchronize data during the
“standby-bulk” state.
Workaround: There is no workaround.
• CSCeb61694
Symptoms: A primary Performance Routing Engine 1 (PRE-1) may reload because of memory
corruption.
Conditions: This symptom is observed on a Cisco 10000 series that is configured with redundant
PREs when you enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on an interface of a 1-port Gigabit Ethernet line card.
Workaround: There is no workaround. Note that the symptom does not occur with a 1-port Gigabit
Ethernet half-height line card.
• CSCeb65079
Symptoms: A Flash-disk timeout error such as the “ATA_Status time out waiting for 1” error may
occur.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0 S and that
is configured with an Advanced Technology Attachment (ATA) Flash disk.
Workaround: To restore proper disk function, remove and reinsert the disk.
• CSCeb65671
Symptoms: An incorrect virtual circuit (VC) disposition label may be generated, causing packets to
drop.
Conditions: This symptom is observed when VC label attributes, such as a control word setting or a
VC type, do not match on a pseudowire.
Workaround: Toggle the interface on which the pseudowire is configured by entering the shutdown
interface configuration command followed by the no shutdown interface configuration command.
• CSCeb66010
Symptoms: An interface may retain its Virtual Private Network (VPN) routing/forwarding (VRF)
configuration when it should not.
Conditions: This symptom is observed when you configure VRF forwarding on a loopback interface
on a provider edge (PE) router, you delete the loopback, and then you add the loopback again.
Workaround: Remove VRF forwarding from the loopback before you delete the loopback.
• CSCeb66997
Symptoms: A Cisco 10720 may reload.
