Resolved Caveats—Cisco IOS Release 12.0(27)S
• CSCec26076
Symptoms: When you enter the interface type 1/0.0 global configuration command to configure
subinterface 0, the command does not configure the subinterface but the main interface; that is, the
command is executed as if you had entered the interface type 1/0 global configuration command.
Conditions: This symptom is observed when you configure an ATM, Fast Ethernet, or Gigabit
Ethernet subinterface; that is you enter atm, fastethernet, or gigabitethernet for the type argument.
Workaround: There is no workaround. You cannot configure subinterface 0. The fix for this caveat
changes the subinterface range from the 0-to-4294967295 range to the 1-to-4294967295 range.
• CSCec26539
Symptoms: A Cisco router that has a Hot Standby Router Protocol (HSRP) group configured on a
subinterface may stop responding and may reload.
Conditions: This symptom is observed when an HSRP Simple Network Management Protocol
(SNMP) query is performed. The symptom occurs only when HSRP is configured on a subinterface.
The symptom does not occur for an HSRP group that is configured on a major interface.
Workaround: Do not initiate an SNMP query for HSRP.
Alternate Workaround: Use the snmp-server global configuration commands to specify which
MIBs are available (for example):
snmp-server view HSRP internet included
snmp-server view HSRP ciscoHsrpMIB excluded
snmp-server view HSRP ciscoHsrpExtMIB excluded
snmp-server community public view HSRP RW 20
snmp-server community private view HSRP RW 20
• CSCec26563
Symptoms: A Cisco router that is in the process of setting up a Multiprotocol Label Switching
(MPLS) traffic engineering (TE) tunnel may reload unexpectedly because of a bus error.
Conditions: This symptom is observed under unusual circumstances when the following series of
events occur:
– You disable MPLS TE tunnels on the router by entering the no mpls traffic-eng tunnels global
configuration command.
– You enter one of the following MPLS TE interface configuration commands on an interface:
mpls traffic-eng attribute-flags attributes
mpls traffic-eng administrative-weight weight
mpls traffic-eng flooding thresholds
– The router attempts to set up a TE tunnel over this interface while the interface state changes to
“up.” (This event causes the router to reload.)
Workaround: Before you enter any of the above-mentioned MPLS TE interface configuration
commands on the interface, ensure that MPLS TE tunnels are enabled on the interface by entering
the mpls traffic-eng tunnels interface configuration command. Before you disable MPLS TE
tunnels on the interface by entering the no mpls traffic-eng tunnels interface configuration
command, ensure that any of the above-mentioned MPLS TE interface configuration commands are
removed from the interface.
