Caveats
Resolved Caveats—Cisco IOS Release 12.0(33)S1
Conditions: This symptom is observed on a Cisco router that functions in a highly scaled
environment involving several hundred VRFs and occurs after the router has been reloaded or after
a switchover has occurred.
Workaround: There is no workaround.
• CSCsk10104
Symptoms: MPLS-TE tunnels do not come up after a core interface is brought down and then up
again by entering the shutdown command followed by the no shutdown command.
Conditions: This symptom is observed when there are 200 MPLS-TE tunnels and 1000 VRFs
configured on an NES-150 and when entering the shutdown command followed by the no
shutdown command for the core interface when the traffic is on for all 1000 VRFs end to end.
Workaround: Enter the no mpls traffic-eng tunnels command followed by the mpls traffic-eng
tunnels command, and all tunnels come up.
• CSCsk15805
Symptoms: If you shut down a TE tunnel interface and you have a static route through the tunnel,
the routing table is not updated immediately but only when the static scan runs (every minute by
default).
Conditions: This problem is fine if the static route is pointing to a physical interface and happens
only with TE tunnel interfaces when it is configured with the ip routing protocol purge command.
Workaround: Remove the ip routing protocol purge command or tune the adjust timer (ip route
static adjust-time command).
• CSCsk26165
Symptoms: A router may crash because of a bus error.
Conditions: The router must be configured for L2TP.
Workaround: There is no workaround.
• CSCsk30571
Symptoms: Field diagnostics fail (indicating a DOWNLOAD FAILURE) on the standby PRP2 when
the PRP2 has 4 GB of memory installed.
After 40 minutes, the default download time limit, field diagnostics declare a download failure and
reload the board. The failure message for this looks like the following:
--------------------------------------------------------------------------- Field Diagnostic:
****DOWNLOAD FAILURE**** while preparing slot {#}
Field Diag eeprom values: run 3 fail mode 5 (DOWNLOAD FAILURE) slot {#} last test failed was
0, error code 0 Shutting down diags in slot {#}
Board will reload ---------------------------------------------------------------------------
Conditions: This symptom is observed for any release of Cisco IOS software when you attempt to
run field diagnostics on a standby PRP that has 4 GB of memory.
Workaround: There is no workaround.
• CSCsk34458
Symptoms: An E5 line card with a 1x10GE SPA can crash when the laser of a JDSU T-BERD 8000
testset that is connected to the 10GE interface is enabled.
Conditions: This symptom is observed on a router that contains an E5 line card with a 1x10GE SPA
and redundant PRP-2 processors that are booted with the c12kprp-p-mz.12.0(32)S7 image and that
are running in RPR+ mode.
