CSCtq22890	Cisco CMTS may crash after jacket card crashes abnormally.
CSCtq27700	PacketCable (PC) Dynamic QoS(DQoS) call does not work. The show packetcable gate summary command output displays the stuck PC DQoS gates in ALLOC state, for the affected PC subscriber.
CSCtq28643	Multicast address shows up wrongly as source address instead of unicast address.
CSCtq29447	When static load balancing with the utilization method is enabled, the Cisco CMTS does not correctly send DS override message to the cable modem, which is connecting to an interface having a load balancing target.
CSCtq34214	IPv6 load balancing on Cisco CMTS does not function properly.
CSCtq35257	Cisco uBR10012 router may crash due to memory allocation failure.
CSCtq35285	The change-trigger value does not reach the CMTS when the cable modem is in partial mode and voice flows are forwarded over the wideband interface.
CSCtq36735	There is no Intermediate System-to-Intermediate System (IS-IS) connection over the 10-Gigabit Ethernet interface in the uBR10012 routers.
CSCtq41613	All cable modems on a Cisco uBR-MC5X20 line card lose connectivity. This is preceded by multiple "%UBR10000-4-BADTXOFFSET:" log messages.
CSCtq43885	The Service Flow Admission Control (SFAC) classification on the PacketCable MultiMedia (PCMM) priority is not working properly.
CSCtq45452	CPE may not receive multicast packets after a line card HA.
CSCtq47448	High upstream utilization is observed on a Cisco uBR-MC20x20V line card after fail over to the protect line card.
CSCtq50591	Multicast packets are wrongly forwarding using the default service flow after line card HA.
CSCtq51989	The PRE4 crashes when it is triggered by show diag x/y conlog command in multiple telnet sessions simultaneously.
CSCtq56713	The following error message is displayed during service flow creation when the CIR utilization for a WB interface is close to its maximum limit. UBR10K-3-QALLOCFAIL: Failure to allocate QoS queue for service flow
CSCtq55998	The route processor CPU is observed to be 99% and the CMTS multicast Q process is observed to be 90% when configuring nearly 100 subinterfaces with a VRF.
CSCtq62767	The PRE may crash with infinite loop during the DHCP configuration.
CSCtq64130	Event-driven database (ETDB) entries may be missing after PRE HA.
CSCtq70677	Additional dummy ETDB entries are listed for the static-multicast after VDOC configuration on the standby PRE.

Resolved Caveats—Cisco IOS Release 12.2(33)SCF

Bug ID	Description
CSCtb73450	Start-Control-Connection-Request (SCCRQ) packets may cause tunnel to reset after digest failure.
CSCtc73759	The H.323 implementation in Cisco IOS Software contains two vulnerabilities that may be exploited remotely to cause a denial of service (DoS) condition on a device that is running a vulnerable version of Cisco IOS Software.
CSCtd75033	Cisco IOS Software is affected by NTP mode 7 denial-of-service vulnerability.
CSCtf74999	A router configured for DLSw might crash when it receives a series of certain malformed packets. This issue requires a number of conditions and a narrow timing window.
CSCth25634	Password is prompted twice for authentication when login authentication has the line password as fallback and RADIUS as primary.
CSCti25339	Cisco IOS device may experience a device reload when the Cisco IOS device is configured for SNMP and receives certain SNMP packets from an authenticated user.
CSCtj56019	Mibwalk dot1dBridge using mst context does not return the correct information.
CSCtl72835	Few wideband cable modems intermittently come online in Partial-mode.
CSCtq02850	On a UBR10012 router with a PRE4, the show environment all command wrongly identifies a UBR10-PWR-AC-PLUS power source as a DC PEM when the Product ID switch on the PEM is illuminated.
