If you do not define this host by specifying an address, theRemote Access Concentrator broadcasts a request and dumps to the firsthost that responds.The Remote Access Concentrator sends a dump to the /usr/spool/erpcd/bfs directory on the dump host. The /usr/spool/erpcd/bfs directory is adefault pathname and can be changed. The receiving Remote AccessConcentrator assigns a unique file name for each device that it receivesa dump from but not for each crash dump.Rename any crash dumps that you want to save. Erpcdoverwrites crash dumps if the same unit dumps again.The assigned name depends on the number of characters per file namethat the dump host supports. For hosts supporting file names longer than14 characters (e.g., most modern UNIX hosts), dump files are nameddump.addr. The file extension addr is the Remote AccessConcentrator’s IP address.
