Resolved Caveats—Cisco IOS Release 12.0(27)S3
4) Symptoms: There are two symptoms:
– There may be a duplicate entry for each file when you enter the show diskslot-number
command.
– An snmpGet on a ciscoFlashFileSize object may enter a loop.
Conditions: This symptom is observed on a router that runs Cisco IOS Release 12.3 T after the
router boots up.
Workaround: There is no workaround.
5) Symptoms: There are two symptoms:
– The show diskslot-number and dir diskslot-number commands may show inconsistent
information.
– Entering the fsck command may delete or truncate the original file.
Conditions: This symptom is observed on a router that runs Cisco IOS Release 12.3 T when an
application or a CLI command overwrites a file on the disk.
Workaround: Reload the router.
6) Symptoms: A router that runs Cisco IOS Release 12.3 T crashes.
Conditions: This symptom is observed when an application creates or opens a file without the
“O_TRUNC” mode and attempts to delete the file, as in the following example:
show version | append disk0:redirect.out" and issuing
delete disk0:disk0:redirect.out
Workaround: Reload the router and delete the file.

Symptoms: Up to 10 percent of packets that are larger than 1496 bytes are dropped when passing
through an Engine 3 4-port GE line card (4GE-SFP-LC).
Conditions: This symptom is observed on a Cisco 12000 series when the line card is used for both
the ingress and egress traffic flow. This situation occurs when SNF is configured on the egress
interface of the affected line card by entering the ip route-cache flow sampled output command.
Workaround: Increase the MTU on any interface of the Engine 4-port GE line card to 1530 bytes to
enable the buffer resources of the line card to be initialized with a larger size.
Alternate Workaround: Decrease the rate of packets drops by increasing the sampling period. For
example, when you enter the ip flow-sampling-mode packet-interval 10 command, up to 10
percent of packets that are larger than 1496 bytes are dropped. However, when you enter the ip
flow-sampling-mode packet-interval 1000 command, only 0.1 percent of packets that are larger
than 1496 bytes are dropped.

Symptoms: On a Cisco 10000 series, the PXF information may not be correctly updated from the
RP after a route change, causing packets to be sent untagged even though the RP shows that the
packets should be sent as tagged.
Conditions: This symptom is observed on a Cisco 10000 series that runs Cisco IOS
Release 12.0(26)S.
Workaround: Enter the clear isis * command or enter the shutdown command followed by the no
shutdown command on the interface towards the MPLS cloud.
