Release Notes for Cisco IOS Release 12.0 S
78-7130-11 Rev. B0
Caveats
• CSCdr06282
A Cisco RSP8 Route Switch Processor (RSP) might run out of buffer headers used for
communication between the Versatile Interface Processors (VIPs) and the RSP. This situation
usually occurs on a Cisco 7500 series router that is configured with several T1 port adapters (PAs).
Communication between the VIP and the RSP is adversely affected, and messages, such as the VIP
notifying the RSP that a line has gone down, might not be completed. You can diagnose this
condition by using the show controllers cbus privileged EXEC command to determine if the
number of buffers in BufhdrQ is near zero. There is no workaround.
• CSCdr13342
A Versatile Interface Processor (VIP) that is running distributed Cisco Express Forwarding (dCEF)
might exhibit the following error message:
%FIB-3-FIBDISABLE: Fatal error, slot 5: No window message, LC to RP IPC is
non-operational
After this error message has been displayed, packets that are traveling on the interfaces of the VIP
might be misdirected. This situation can be fixed by entering the clear cef linecard [slot-number]
EXEC command, but the VIP might reload with a memory corruption shortly after the command is
entered if the VIP is under a very high load. There is no workaround.
• CSCdr35103
The SA-COMP compression service adapter (CSA) is supported only on VIP2-50 Versatile
Interface Processors (VIPs) with revision C0 or later revisions. If the SA-COMP CSA is used with
an earlier revision, the router will experience a VIP reload, and the VIP will become disabled. There
is no workaround.
• CSCdr52041
A Cisco 7500/RSP series router with an RSP4 Route Switch Processor that is running the
rsp-pv-mz.120-10.S.bin image might exhibit QA errors, and the RSP might restart with a cBus
complex. In at least one instance, this condition occurred after the router was upgraded from Cisco
IOS Release 12.0(9)S because of Multiprotocol Label Switching (MPLS) problems. There is no
workaround.
• CSCdr66353
A Cisco router with a Network Processing Engine-300 (NPE-300) that is running Cisco IOS
Release 12.0(10)S might reload when the temperature on outlet 3 of the NPE reaches a warning
temperature. When the temperature in outlet 3 has reached a warning state for a high temperature,
the following error message is exhibited:
%ENVM-4-ENVWARN: chassis outlet 3 measured at 52C/125F
There is no workaround.
• CSCdr71075
The following problems have been observed in Cisco IOS Release 12.0(10.3)S:
– The ifNumber that is returned by Simple Network Management Protocol (SNMP) is incorrect.
– Frame Relay subinterfaces are missing from the ifTable and the ifXTable.
– The ifStackTable does not exhibit the same number of interfaces as is indicated by ifNumber
ifIndices.
There is no workaround.
