Resolved Caveats—Cisco IOS Release 12.0(28)S
CSCed46856
Symptoms: Most multicast traffic is dropped if an ingress interface is an interface of an E4+ line
card and NetFlow is configured.
Conditions: This symptom occurs when multicast traffic is forwarded down a shared tree, for
example, forwarded by (*, g).
Workaround: Either unconfigure NetFlow or disable the SPT threshold to move to the shortest path
tree.
CSCed47409
Symptoms: In Cisco IOS software that is running Multiprotocol Label Switching (MPLS), a router
may reload after accessing a freed Label Information Base (LIB) entry. When the symptom occurs,
an error message similar to the following is likely to precede the reload:
%TIB-3-LCLTAG: 10.10.10.10/10.10.10.10, tag advert; unexpected tag state=13
Conditions: This symptom is observed when a very uncommon timing of a Label Distribution
Protocol (LDP) events occurs. The symptom may occur with LDP or Tagswitching Distribution
Protocol (TDP).
Workaround: There is no workaround.
CSCed47967
Symptoms: The line protocol may be in a DOWN state on the Ethernet interface of a Cisco
7206VXR with an NPE-400 and a 7200-I/O-GE+E I/O controller when the interface of the
connected device is set to 10-Mbps operation. Additionally, the output of the show controller e0/0
command may indicate that the hardware is set to an incorrect speed.
Conditions: This behavior appears to be limited to the 7200-I/O-GE+E I/O controller and occurs
consistently upon bootup.
Workaround: Configure the speed of the interface of the connected device to 100 Mbps (both
full-duplex and half-duplex settings will work).
CSCed48824
Symptoms: A router may crash when you remove a VLAN subinterface while traffic is being
forwarded out of this subinterface.
Conditions: This symptom is observed on a Cisco 12000 series that runs the gsr-p-mz image of
Cisco IOS Release 12.0(28)S.
Workaround: Ensure that no traffic is forwarded out of the subinterface before you remove it.
CSCed48941
Symptoms: A Cisco MGX 8800 series Route Processor Module XF (RPM-XF) may crash and
generate the following error message:
No memory for XCM tempbuffer logged
Conditions: This symptom is observed on an RPM-XF that functions as a provider edge (PE) router
in a Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN) when you enter the
clear interface sw1 command multiple times on the RPM-XF.
Workaround: There is no workaround. The fix for this caveat is also integrated in images that support
the Cisco 10000 series, such as Cisco IOS Release 12.0 S.
CSCed49303
Symptoms: A Cisco 12000 series that runs 12.0(25)S2 may report the following log message:
SLOT 1: %SYS-3-CPUHOG: Task ran for 2052 msec (1/1), process = CEF LC IPC
