4.8SAVING CORE DUMPS

The SmartCell ZX-250 core dump feature allows you to specify a local Ethernet host where, in the event of a system failure, the SmartCell ZX-250 sends a copy of its memory. SmartCell ZX-250 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.

2p›F 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.
