Resolved Caveats—Cisco IOS Release 12.0(27)S
• CSCin49458
Symptoms: Pings between two customer edge (CE) routers may fail.
Conditions: This symptom is observed after a high traffic load has occurred for a short period of
time on Any Transport over Multiprotocol Label Switching (AToM) Layer 2 Tunneling Protocol
version 3 (L2TPv3) virtual circuits (VCs). The VCs stay up, but pings may fail.
Workaround: Reload the microcode onto the line card on which the VCs are configured.
• CSCin49862
Symptoms: When the Any Transport over MPLS (AToM): ATM Cell Relay over MPLS feature is
configured in virtual circuit (VC) mode or virtual path (VP) mode, not all AToM VCs or VPs may
become established, and the output of the debug xconnect error privileged EXEC command may
display the following message:
XC AUTH [<ipaddr>, <vcid>]: Mismatch MTU
Conditions: This symptom is observed on a Cisco 7500 series that is configured with a large number
of ATM over Multiprotocol Label Switching (ATMoMPLS) cell mode circuits (more than 1000
ATM VCs or VPs) when interfaces flap, causing all VCs or VPs to attempt to reestablish themselves
simultaneously.
Workaround: Deconfigure the Any Transport over MPLS (AToM): ATM Cell Relay over MPLS
feature from the affected VC or VP; then, reconfigure the feature on the VC or VP.
• CSCin50883
This caveat consists of four symptoms, four conditions, and a single workaround for all four
symptoms and conditions:
Symptom 1: A “PCMCIA-DIBERR” error message may be displayed.
Condition 1: This symptom is observed when you enter the show flash-filesystem: EXEC command
for a Personal Computer Memory Card International Association (PCMCIA) disk that is formatted
for low-end file system (LEFS).
Symptom 2: An “Invalid DOS Media” error message may be displayed.
Condition 2: This symptom is observed when you remove a compact Flash card that is formatted for
MS-DOS FS, you replace it with one that is formatted for LEFS, and you enter the show:
flash-filesystem: EXEC command.
Symptom 3: A compact Flash card that is configured for LEFS may not be recognized.
Condition 3: This symptom is observed when you perform an online insertion and removal (OIR)
and you replace an Advanced Technology Attachment (ATA) Flash card with a compact Flash card
that is configured for LEFS.
Symptom 4: A traceback for a duplicate file system may be generated in the file system table.
Condition 4: This symptom is observed when you perform an OIR and you replace a compact Flash
card that is configured for LEFS with an ATA Flash card.
Workaround for all four symptoms and conditions: Before you enter any command or perform an
OIR, enter the show version EXEC command. Doing so forces the PCMCIA card or the compact
Flash card to be reread and clears the difficulties.
