• CSCsa86214
Symptoms: Locally-originated and transit packets that are greater than 1599 bytes in length do not
leave a router. BGP and other TCP-based protocols that negotiate large MSS values may go down.
Conditions: This symptom is observed on a Cisco 10000 series that is configured with a PRE or
PRE1 and that performs IP fragmentation.
Workaround: First, enter the show hardware pxf cpu buffer or show pxf cpu buffers command to
verify buffer depletion. Then, perform a microcode-reload of the PXF engine.
• 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
Conditions: This symptom is observed on a Cisco 12000 series when a POS interface of an Engine 0
or Engine 2 line card has the tx-cos command enabled and is a member of a port channel or POS
channel.
Workaround: There is no workaround.
