78-7130-11 Rev. B0
Caveats
Miscellaneous
• CSCdm70554
A Gigabit EtherChannel (GigE) line card might pause indefinitely in FABL START state when the
secondary Gigabit Route Processor (GSR) is in the chassis.
Workaround: Remove the secondary Gigabit Route Processor (GSR).
• CSCdm72149
When formatting a PCMCIA card with Cisco IOS Release 12.0 S, the command might fail if you
have not formatted your bootflash.
Workaround: Format your bootflash and try the operation again.
• CSCdm74152
A Cisco router that is running Cisco IOS Release 12.0(4.6)T through 12.0(5)T might experience
problems with fast switching if Cisco Express Forwarding (CEF) is disabled.
Workaround: Enable Cisco Express Forwarding (CEF), and then disable CEF to remove it from the
unwanted interfaces.
• CSCdm77266
A Cisco 12000 router that is running the “gsr-k4-p” software image in Cisco IOS
Release 12.0(5.5)S2 might reload if you simultaneously configure Border Gateway Protocol (BGP)
neighbors and static routes and Multicast Source Discovery Protocol (MSDP). There is no
workaround.
• CSCdm89160
After you upgrade the ROM monitor on a Cisco router, the router might not reload properly and
exhibit the following error message:
*** Cache Error Exception *** Cache Err Reg = 0xa4240560 data reference, primary
cache, data field error , error on SysAD Bus PC = 0xbfc00e04, Cause = 0x8000,
Status Reg = 0x30408404 Tiger Masked Interrupt Register = 0x000000ff Tiger
Interrupt Value Register = 0x0000000c
This situation occurs only when the following conditions exist:
1) The router is running one of the following IOS software images: 11.2(17)GS1; 12.0(5.5)S1 and
later versions prior to this fix; 12.0(5.6)S and later versions prior to this fix; or 12.0(6.0.2)S and
later versions prior to this fix.
2) You have manually upgraded the ROM monitor using either the
upgrade rom slot [RP-slot#] command or the upgrade all all command. If you used the
upgrade all all command, answering “yes” when prompted to upgrade the Route Processor (RP)
ROM monitor will cause this situation to occur.
Workaround: Do not upgrade the ROM monitor.
• CSCdp00618
A Route/Switch Processor (RSP) might reload while unprovisioning a channelized interface under
heavy traffic. There is no workaround.
