Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S4
• CSCsc69537
Symptoms: A Cisco 12000 series may report incorrect ifIndex values in the NetFlow Data
Export (NDE) packets that are sent from a Gigabit Ethernet (GE) ISE line card. Flows that arrive via
VLAN subinterfaces may be reported as zero with the SNMP ifIndex or as the ifIndex of the physical
GE interface.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(30)S3 or a later release after you have reloaded the GE line card.
Workaround: There is no workaround. When the symptom has occurred, re-apply the configuration
of the subinterfaces.
IP Routing Protocols
• CSCef60452
Symptoms: A router may stop receiving multicast traffic.
Conditions: This symptom is observed rarely during convergence when a router receives a Join
message on an RPF interface and when a downstream router converges faster than the first router
that receives the Join message.
In this situation, the router does not populate the RPF interface into the OIL (that is, the OIL remains
null) because the old SP-tree has already been pruned by the downstream router. When the RPF
interface of the router changes to the new path later, it does not trigger a Join message toward the
multicast source until the router receives a next periodic Join message from the downstream router
and populates the OIL. As a result, multicast traffic stops temporarily but no longer than the periodic
Join message interval.
Workaround: There is no workaround.
• CSCsb79749
Symptoms: The output of the show memory summary command may contain garbled characters in
the “What” column.
Conditions: This symptom is observed when you configure OSPF with at least one network, and then
unconfigure it.
Workaround: There is no workaround.
• CSCsc59089
Symptoms: BGP does not advertise all routes to a peer that sends a route-refresh request.
Conditions: This symptom is observed under the following conditions:
–
The router is in the process of converging all of its peers and has updates ready in the output
queue for the peer.
–
The peer sends a route-refresh request to the router. This may occur when the clear ip /jointfilesconvert/415844/bgp *
soft in command is entered on the peer or when a VRF is added to the peer.
–
The router processes the route-refresh request from the peer while the router still has updates in
the output queue for the peer.
In this situation, all of prefixes that are advertised by the unsent updates in the output queue for the
peer are lost.
Workaround: There is no workaround. When the symptom has occurred, enter the clear ip /jointfilesconvert/415844/bgp *
soft out command on the router to force the router to send all updates to its peers.
