Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S
Workaround: There is no workaround.
• CSCsa97238
Symptoms: A 2.5G ISE SPA Interface Processor (SIP) in which a 4-port channelized T3 to DS0
Shared Port Adapter (SPA) is installed crashes when the controller is reconfigured and VRFs are
present or have been present on the associated interfaces.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(31)S.
Workaround: There is no workaround.
Further Problem Description: The SIP and SPA do not recover on their own; you must reload the
router to recover the SIP and SPA.
• CSCsa99212
Symptoms: Traffic man continue to pass for a period of time on an AToM session even when the
LDP session between two PE routers is disrupted.
Conditions: This symptom is observed on a Cisco router that functions as a PE router when it
receives an LDP DOWN event.
Workaround: There is no workaround.
• CSCsa99983
Symptoms: New AToM or L2TPv3 sessions may not come up.
Conditions: This symptom is observed on a Cisco router that is configured for Multilink Frame
Relay (MFR) over L2TPv3/AToM when there are services with incomplete MFR over
L2TPv3/AToM configurations and when the router has run for a long period of time.
Workaround: There is no workaround.
• CSCsb00493
Symptoms: Packets do not switch through a core interface of a line card that has hardware
acceleration enabled.
Conditions: This symptom is observed on a Cisco 12000 series when the line card that contains the
core interface has also a VRF interface that is shut down.
Workaround: Disable hardware acceleration on the line card.
• CSCsb01188
Symptoms: An ATM subinterface on an ATM port adapter that is installed in a FlexWan module or
VIP may transition to the down/down state.
Conditions: This symptom is observed on a Cisco Catalyst 6500 series, Cisco 7500 series, and
Cisco 7500 series when you remove a QoS service policy from the ATM subinterface.
Workaround: There is no workaround.
• CSCsb02061
Symptoms: An “Output Hold Queue Wedge” condition may occur on PVCs that are defined on DS1
ports that are not configured for IMA.
Conditions: This symptom is observed on a Cisco 7200 series that runs the c7200-ik9s-mz image of
Cisco IOS Release 12.3(13), that is configured with a PA-A3-8T1-IMA port adapter that is
configured for DSL aggregation, and that terminates hundreds of UBR VCs on a DS1 interface. The
“Output Hold Queue Wedge” condition occurs on idle subinterfaces or when multiple point-to-point
subinterfaces are “spawned” from a single subinterface by entering a PVC range command such as
the following:
