Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S
CSCsa91478
Symptoms: A Cisco 12000 series that is configured for L2TPV3 may continuously log the following
CM_ERROR message, causing the syslog server to be flooded:
%SW_MGR-3-CM_ERROR: Connection Manager Error - unprovision segment failed
%SW_MGR-3-CM_ERROR: Connection Manager Error - unprovision segment failed
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(30)S1 when a Multilink Frame Relay (MFR) interface is shut down in the
configuration of the connect command, causing proper provisioning to fail, unprovisioning to occur,
and the error message to be generated.
Possible Workaround: Enter the no shutdown interface configuration command on the MFR
interface.
CSCsa93814
Symptoms: When you send a high rate of bidirectional unicast and multicast traffic, the PXF
complex can crash and then recover on its own.
Conditions: This symptom is observed on a Cisco 10720 when a high rate of bidirectional unicast
and multicast traffic is sent between GE ports across an SRP uplink.
Workaround: There is no workaround.
CSCsa93883
Symptoms: No error condition is detected when a properly structured IPv4 packet has an invalid
version value in the IP header. For example, IPv4 packets that have a version value other than 4 are
forwarded without an error.
Conditions: This symptom is platform-independent and occurs under normal operating conditions.
Workaround: There is no workaround.
CSCsa96275
Symptoms: When you send traffic with the full bandwidth of an IMA bundle, cell loss occurs. For
example, cell loss occurs when you send traffic with more than 5 Mbps on an 8-link T1 IMA group
or with 6.4 Mbps on an 8-link E1 IMA group.
Conditions: This symptom is observed on a Cisco 7500 series that runs Cisco IOS Release 12.0(30)S
and that is configured for ATM L2TPV3, cell-packing, and multiple VP configurations. There is no
cell loss with a single PVC without an L2TPv3 configuration.
Workaround: There is no workaround.
CSCsa96941
Symptoms: When VBR ATM traffic is sent through a Cisco 12000 series 4-port ATM OC-3 ISE line
card via an L2TPv3 IP tunnel to another 4-port ATM OC-3 ISE line card on another
Cisco 12000 series, the VBR ATM traffic passes at lower rates than what is configured on the
routers, and cell loss occurs.
Conditions: These symptoms are observed on a Cisco 12000 series that is connected back-to-back
via an OC-192 POS link to another Cisco 12000 series.
Workaround: There is no workaround.
CSCsa97090
Symptoms: A FIBNULLIDB error may occur on a Cisco platform that is configured for CEF.
Conditions: This symptom is observed under several conditions such as deleting a subinterface or
performing an OIR of a new line card.
