Resolved Caveats—Cisco IOS Release 12.0(31)S4
Cisco IOS Release 12.0(31)S4 is a rebuild of Cisco IOS Release 12.0(31)S. The caveats listed in this
section are resolved in Cisco IOS Release 12.0(31)S4 but may be open in previous Cisco IOS releases.
This section describes only severity 1, severity 2, and select severity 3 caveats.
Basic System Services
CSCed44414
Symptoms: When the slave RSP crashes, a QAERROR is observed in the master console, resulting
in a cbus complex. The cbus complex will reload all the VIPs in the router.
Conditions: This symptom happens when the slave crashes in a period when there is a large number
of packets going towards the RSP. A large number of packets go to the RSP when CEF switching is
configured or when routing protocol updates are numerous.
Workaround: There is no workaround.
CSCee41892
Symptoms: A VIP4-80 card may fail to load the Cisco IOS software image. When this situation
occurs, the following error messages are generated:
%DBUS-3-SW_NOTRDY: DBUS software not ready after HARD_RESET, elapsed 13056, status 0x0
%DBUS-3-WCSLDERR: Slot 2, error loading WCS, status 0x4 cmd/data 0xDEAD pos 97
%DBUS-3-WCSLDERR: Slot 2, error loading WCS, status 0x4 cmd/data 0xDEAD pos 99
%UCODE-3-LDFAIL: Unable to download ucode from system image in slot 2, trying rom
ucode
%RSP-3-NOSTART: No microcode for VIP4-80 RM7000 card, slot 2
Conditions: This symptom is observed on a Cisco 7500 series when you enter the micrcode reload
command.
Workaround: There is no workaround.
Further Problem Description: The symptom may also occur because of improperly installed line
cards. If this situation occurs, re-install the line cards.
CSCej08355
Symptoms: The active Supervisor Engine or Route processor (RP) may reload when the standby
Supervisor Engine or RP is inserted.
Conditions: This symptom is observed on a Cisco switch or router when the following conditions
are present:
The SSO redundancy mode is configured.
The snmp mib notification-log default command is enabled.
Workaround: Do not configure SSO as the redundancy mode. Rather, configure RPR+ as the
redundancy mode.
Alternate Workaround: Disable the SNMP MIB notification log by entering the no snmp mib
notification-log default command.
CSCin86930
Symptoms: Incoming ATM traffic is dropped from interfaces of an ATM port adapter because the
usage of the CPU increases to 100 percent on the VIP.
Conditions: This symptom is observed on a Cisco 7500 series that is configured with 1000 ATM
AAL5 over MPLS (AAL5oMPLS) VCs and that processes 1000 pps (512 kbps) of traffic.
