Caveats
Resolved Caveats—Cisco IOS Release 12.0(30)S
Workaround: There is no workaround.
• CSCee63939
Symptoms: An Engine 6 line card may crash during the MDFS process.
Conditions: This symptom is observed on a Cisco 12000 series when multicast and unicast traffic
are running through the Engine 6 line card.
Workaround: There is no workaround.
• CSCee65004
Symptoms: A 1-port 10-Gigabit Ethernet line card (1X10GE-LR-SC) may crash, reporting
%TX192-3-CPUIF errors.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(27)S1 when you shut down the 10GE port of a 4-port 10 Gigabit Ethernet module
(WS-X6704-10GE) that is installed in a Cisco 7609 at the other side of the connection.
Workaround: There is no workaround.
• CSCee67207
Symptoms: A public recursive route is not labeled.
Conditions: This symptom is observed on a Cisco router that functions as a BGP peer and that has
the neighbor name send-label command enabled as part of an IPv4 address family, which is
required for Inter-AS configurations. The symptom affects routers that perform MPLS forwarding
using ASICs such as some Cisco 7200 series routers, the Cisco 7304, the Cisco 10000 series, the
Cisco 12000 series, and the Cisco RPM-XF. (This list may not be exhaustive.)
Workaround: There is no workaround. Note that the symptom does not occur if the neighbor name
send-label command is enabled as part of an IPv4 address family VRF.
• CSCee67746
Symptoms: An E4+ POS line card reports %TX192-3-PAM_MODULE and %TX192-3-PAM_PIM
errors. On rare occasions the line card may crash when it receives a malformed packet.
Conditions: These symptoms are observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(25)S3 or Release 12.0(26)S4.
Workaround: There is no workaround.
• CSCee68666
Symptoms: It may take up to 1 second for a line card to notify the RP about a physical layer failure
alarm. This situation prevents fast sub-second IGP convergence.
Conditions: This symptom is observed in a non-FRR and non-APS configuration.
Workaround: There is no workaround.
• CSCee70478
Symptoms: If hardware multicast forwarding is enabled on an Engine 2 line card that is connected
to the source of multicast traffic, multicast traffic may not be forwarded after the router has reloaded.
Conditions: This symptom is observed on a Cisco 12000 series that runs the gsr-p-mz image of
Cisco IOS Release 12.0(27)S2.
Workaround: Remove and reapply hardware multicast forwarding to the line card.
• CSCee70591
Symptoms: A Cisco 7500 series T3 port adapter (PA-2T3+) may not provide a two-second delay
before bringing down the T3 controller.
