Resolved Caveats—Cisco IOS Release 12.0(30)S
All the caveats listed in this section are resolved in Cisco IOS Release 12.0(30)S. This section describes
only severity 1, severity 2, and select severity 3 caveats.
Basic System Services
• CSCed67358
Symptoms: An IPv6 PIM neighbor may be down after changing the PIM configuration.
Conditions: This symptom is observed when the no ipv6 pim command is entered on some
subinterfaces of a physical Ethernet interface and when PIM is enabled on several subinterfaces of
the same physical Ethernet interface. The symptom affects both IPv4 and IPv6, and configurations
with multicast and OSPF Hello messages.
Workaround: There is no workaround.
• CSCee04316
Symptoms: A TN-2-BADCONN message may appear in the log and may be quickly followed by an
FIB Disable message, indicating that distributed CEF is disabled on all VIPs. The IPC buffers usage
may grows very large (up to 600 MB) and these buffers may not be reclaimed.
Conditions: This symptom is observed on a Cisco 7500 series that runs Cisco IOS
Release 12.0(26)S1 and that has a very large BGP table and several VRFs.
Workaround: Reload the router to restore normal operation.
• CSCee78266
Symptoms: A Cisco 7500 series may reload in an indefinite loop when you unintentionally enter the
show list number hidden command.
Conditions: This symptom is observed when you, for example, abbreviate the show line 2000
command as the show li 2000 command and actually execute the show list 2000 hidden command.
Workaround: Do not abbreviate the show line command as the show li command but enter the full
command.
• CSCee87891
Symptoms: SNMP entries may be deleted when you configure SNMP or when you reload the router
on which SNMP is configured.
Conditions: This symptom is observed when an SNMP user is configured with the same name or
host name as a community.
Workaround: There is no workaround.
• CSCee95282
Symptoms: A router may generate a very large remote processing time report that may take between
10 and 25 seconds to be generated.
Conditions: This symptom is observed when you enter the rtr responder command for the first time
and you do not reload the router.
Workaround: Reload the router after you have entered the rtr responder command.
