Resolved Caveats—Cisco IOS Release 12.0(28)S6
• CSCsb62041
Symptoms: A newly created channelized interface may show packet and byte counts before any
traffic passes through the interface.
Conditions: This symptom is observed on a Cisco 12000 series. When a channelized interface is
deleted, the interface index is released. This interface index may be re-allocated when a new
channelized interface is created. The counters that are associated with the index need to be cleared
when an interface is deleted so that they are properly initialized if the index is subsequently
re-allocated to a new interface.
Workaround: There is no workaround. Although you can clear the interface counters via the CLI,
doing so does not prevent the symptom from occurring because but there is an internal counter that
is used in the Tx byte and packet counts and that may cause errors in the calculations.
• CSCsb75433
Symptoms: Distributed Multilink PPP (dMLP) packets are not switched via dCEF.
Conditions: This symptom is observed on a Cisco router that is configured with multilink bundles.
Workaround: There is no workaround.
• CSCsb88214
Symptoms: SNMP polling via the CBQoSMIB on the cbQosPoliceStatsTable returns no results.
Conditions: This symptom is observed on a Cisco 7500 series that has policing defined in a class
map.
Workaround: There is no workaround.
• CSCsb98254
Symptoms: A router may fail when you reload a Gigabit Ethernet (GE) line card or port adapter that
has link-bundling enabled.
Conditions: This symptom is observed on a Cisco router when dot1q is configured on a GE interface
of the line card or port adapter and when MPLS is enabled on an uplink.
Workaround: There is no workaround.
• CSCsc08181
Symptoms: The PXF engine reloads when you enter the service-policy output command.
Conditions: This symptom is observed on a Cisco 10000 series router when the following conditions
are present:
– The frame-relay fragment command is configured on a Frame Relay interface.
– An output service policy that has the bandwidth, priority, or shape command enabled is
applied to a Frame Relay permanent virtual circuit (PVC).
Workaround: Do not combine interface-based Frame Relay fragmentation with a PVC-based service
policy. Rather, either apply both Frame Relay fragmentation and a service policy to the physical
interface or apply both Frame Relay fragmentation and a service policy to the Frame Relay PVC.
• CSCsc37404
Symptoms: An Engine 6 line card may reset with the following error messages:
%IPC-5-INVALID: NACK Source Port=0x403F0000
%MCC192-3-CPU_PIF: Error=0x4
