Resolved Caveats—Cisco IOS Release 12.0(30)S3
Conditions: This symptom is observed on a Cisco 12000 series that runs a Cisco IOS software
release that includes the fix for caveat CSCef06121. A list of the affected releases can be found at
http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCef06121. Cisco IOS
software releases that are listed in the “First Fixed-in Version” field at this location are affected.
Workaround: There is no workaround. The symptom causes a disruption of service, but service is
restored.
Further Problem Description: When the symptom occurs, the following messages are generated in
the log:
%RP-3-FABRIC_UNI: Unicast send timed out (1)

• CSCsa86214
Symptoms: Locally-originated and transit packets that are greater than 1599 bytes in length are not
exiting the router. BGP and other TCP based protocols that negotiate large MSS values may go
down.
Conditions: This symptom may occur when any PRE/PRE1-based Cisco 10000 router is doing IP
fragmentation.
Workaround: Use the show hardware pxf cpu buffer command or show pxf cpu buffers command
to verify buffer depletion. Perform a microcode reload of the PXF.
• CSCsa87295
Symptoms: Traffic to a network core is dropped from a link-bundle interface of an Engine 3 line
card.
Conditions: This symptom is observed when the network core is a Cisco 12000 series that runs
Cisco IOS Release 12.0(26)S or a later release, that functions as a PE router, that is configured for
MPLS VPN, and that has L3 loadbalancing enabled on an egress path through a link-bundle
interface.
Workaround: There is no workaround.
Further Problem Description: The symptom occurs because there is incorrect FCR information in
the Engine-3 hardware rewrites that point to the link-bundle interface.
• CSCsa88211
Symptoms: When you boot a Cisco 12000 series, some Layer 1 and CoS command are rejected with
the following error messages:
Command "pos threshold sd-ber 9" not allowed on link-bundle member interface POS1/0
Command "tx-cos TEST" not allowed on link-bundle member interface POS1/0
