Creating Core Dump Files

You can enable the system to create a core dump file if a module fails. You can choose to send the core dump file to an FTP server or save the file to NVS. Juniper Networks Customer Service can then access the core dump file and analyze it to determine what went wrong. Local core dumps—stored in NVS—are enabled by default. You can enable the core dump from Boot mode or Global Configuration mode.

Caution: Create a core dump file only under the direction of Juniper Networks Customer Service. Network function can be disrupted if you create a core dump file while the system is running in a network.

On the E120 router and the E320 router, the failure of some components on a line module generates multiple core dumps to provide more complete information about system state at the time of the failure. Other E-series routers generate only a single core dump for line module failures. When you contact Juniper Networks Customer Service for assistance, send all of the generated core dump files.
