Saving Core Dumps

9.6SAVING CORE DUMPS

The ATM SmartSwitch core dump feature allows you to specify a local Ethernet host where, in the event of a system failure, the ATM SmartSwitch sends a copy of its memory. ATM SmartSwitch system memory is saved to two files, one containing CPU memory (core_cpu), the other common memory (core_cmn). These files can then be sent to Cabletron customer support for analysis.

Note To use the core dump feature, the local Ethernet host must be running TFTP server software, and you must have write access to the TFTP directory.

Enter the set coredump command to enable the core dump feature. For example,

SmartSwitch # set coredump

 

 

EnableCoreDump(n)

: y

— “y” to enable core dump feature

ServerIP()

: 204.95.77.240

— IP address of my TFTP server

CoreDumpFile()

: /tftpboot/bobr/core

— full path name for core dump files

userName()

: bobr

— login name on the server

UserPassword()

:

— password

SmartSwitch #

 

 

Note The set coredump command uses FTP to create the core_cpu and core_cmn files. If your server does not run FTP, create these files manually. Then execute the

set coredump command.

Note On UNIX systems, make sure that the permissions are set correctly so that data can be written.

Note For security, the set coredump command retains your password only long enough to create the core dump files. Your password is then dropped from system memory.

To see the current core dump configuration, enter the show coredump command.
