Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S
Conditions: This symptom is observed on a Cisco 7500 series that runs Cisco IOS Release 12.0S
when QoS is configured on at least one interface on the VIP in which the channelized port adapter
is installed. The symptom occurs after the affected interface has flapped very frequently because of
OSI layer 1 errors.
Workaround: Remove and reconfigure the controller of the affected interface.
• CSCei94893
Symptoms: AToM PVCs on an MFR interface that has keepalives disabled do not pass traffic after
the router is rebooted.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS Release 12.0S.
Workaround: Enable LMI keepalives.
• CSCsa73905
Symptoms: The L2TP management daemon process may leak memory if the parsing of some L2TP
control messages fails.
Conditions: This symptom is observed on a Cisco router that is configured or VPDN L2TP tunnels
when PPPoE sessions were brought up and down after a period of time.
Workaround: There is no workaround.
• CSCsa87205
Symptoms: A router that is configured for PPP Multilink reloads because of a bus error.

• CSCsb61367
Symptoms: When you enter the redundancy force-switchover command on a router that is
configured for PPP encapsulation, the IS-IS neighbor comes up in the INIT state.
Conditions: This symptom is observed on a Cisco router that is configured with two RPs that run in
in SSO redundancy mode.
Workaround: To bring up the IS-IS state in the IS-IS neighbor, enter the isis protocol shutdown
interface configuration command followed by the no isis protocol shutdown interface
configuration command on interface that provides the connection to the IS-IS neighbor.
Alternate Workaround: Configure HDLC encapsulation on the router.
