FTOS Configuration Guide for the C-Series - Force10 Networks

The kernal core dump is enabled by default for RP. The kernel core dump feature for CP is disabled by
default. Enable it using the command logging coredump cp from CONFIGURATION mode.
• If you use the keyword cp with this command, the system creates a file named f10co.kcore.gz that
preserves space on the internal flash so that there is always enough space for a core dump. Undoing
this command using the no logging coredump cp removes this file.
• You may choose to write the core dump directly to an FTP servers using the keyword server. However,
the server option supports only RP coredumps it does not support CP coredumps.
Port Shutdown for Redundant System Failover
Port Shutdown for Redundant System Failover is supported on platforms c e
The FTOS line card dump currently takes from 5 to 30 minutes to upload to memory on the RPM. During
this time, the physical interfaces retain their current state, which normally is operationally up. This
behavior assumes that most FTOS agent tasks running on the LP continue to operate correctly and that you
want to maximize uptime by having packets continue to flow while the core dump is being written.
If you want to failover to a redundant system then this assumption is not correct. In this case, use the
command logging coredump linecard port-shutdown (Figure 26), to shut down ports during a core dump
so that the backup system can take over.
Note: Configure the port shutdown before a software exception.
In Figure 26, the ports on line card 13 shut down while the ports on line card 0 remain up during a core
dump.
