Resolved Caveats—Cisco IOS Release 12.0(27)S3
• CSCef16326
Symptoms: When you remove a policy map from a subinterface, the subinterface may become stuck,
preventing traffic from passing through the subinterface.
Conditions: This symptom is observed on a Cisco 10000 series that runs Cisco IOS
Release 12.0(25)SX7 when a nested policy map is applied to the main or physical interface in
addition to the one that is already applied to the subinterface. The symptom could also occur in
Release 12.0S.
Workaround: Remove the policy map from the physical interface before you remove the policy map
from the subinterface. When the subinterface configuration is updated, re-apply the policy map to
the physical interface.
• CSCef23821
Symptoms: Packet latency in a priority class is high when shaping is enabled in the parent class. For
example, when you send 400 kbps of traffic through the priority class, the measured latency is about
80 ms.
Conditions: This symptom is observed when the service policy has a shape average of 768000 on
the class default and a child policy with a priority feature.
Workaround: There is no workaround.
• CSCef24642
Symptoms: The PXF engine on a Cisco 10720 may crash, and the following error messages are
generated in the logging buffer (the PXF crashinfo files can be found in the flash memory of the
router):
MSD: %TOASTER-2-FAULT: T0 IHB Exception: watchdog
MSD: %TOASTER-2-FAULT: T1 IHB Exception: watchdog
MSD: %TOASTER-2-FAULT: T0 IHB Exception: watchdog
MSD: %TOASTER-2-FAULT: T1 IHB Exception: watchdog
In addition, there are four ways to verify that the symptom is occurring:
– If the debug main error, debug uplink error, and debug access error commands are enabled
on the router, the following error messages are also generated in logging buffer:
MSD: %Camr_SRP_OC48-3-INTERR: SRP uplink internal error SRP_TX_VA_SC_GIANT_PKT
(code 4)
MSD: %Camr_SRP_OC48-3-INTERR: SRP uplink internal error
SRP_TX_VA_SC_FIFO_GIANT_PKT(code 100)
MSD: %Camr_VA-3-STATUS1: Van Allen Data integrity error
VA_SC_IPM_RD_ACC_TIMER_EXP(code 1)
MSD: %Camr_VA-3-STATUS1: Van Allen Data integrity error
VA_RP_IPM_RD_ACC_TIMER_EXP(code 4)
MSD: %Camr_VA-3-SISTATUS: Van Allen SRIC Data integrity error
VA_SI_FL_CTRL_DRVN(code 80)
MSD: %Camr_VA-3-SOSTATUS: Van Allen SROC Data integrity error VA_SO_PKT_LEN_ERR
(code 1)
MSD: %Camr_VA-3-STATISTICS: VA statistics register: 0x0098 reports
VA_SO_PKT_LEN_ERR_COUNT = 3
– In the output of the show interface srp 1/1 command, the received error counters such as
“framer runts” and “input errors” have a large value.
– In the output of the show hard pxf cpu statistics interface srp 1/1 detail command, the
“destination unreachable” counter increases.
