Description

Show core files on all routers or switches running Junos OS Evolved. You use this command to show a list of system core files created when the device has failed, which can be useful for diagnostic purposes. Each list item includes the file permissions, number of links, owner, group, size, modification date, and path and filename.

Note:

For Junos OS Evolved, if dual Routing Engines are present, the command lists the core-dump files for both Routing Engines.
