Command introduced before JUNOS Release 8.5.
sfc option introduced for the TX Matrix Plus router in JUNOS Release 9.6.
Show core files on all JUNOS routers. You can use the show system core-dumps command to show a list of system core files created when the router has failed. This command can be useful for diagnostic purposes. Each list item includes the file permissions, number of links, owner, group, size, modification date, and path/filename.
You can use the option core-filename and its options core-file-info, brief, and detail to display more information about the specified core-dump files.
none — Display a list of all existing core-dump files.
all-chassis — (TX Matrix and TX Matrix Plus routers only) (Optional) Display logging information about all the T640 routers (in a routing matrix based on the TX Matrix router) or T1600 routers (in a routing matrix based on the TX Matrix Plus routing matrix) in the chassis.
<all-lcc | lcc number> — (TX Matrix and TX Matrix Plus routers only) (Optional) On a TX Matrix router, display logging information about all T640 routers (or line-card chassis) or a specific T640 router connected to the TX Matrix router. On a TX Matrix Plus router, display logging information about all T1600 routers (or line-card chassis) or a specific T1600 router connected to the TX Matrix Plus router. Replace number with a value from 0 through 3. .
scc — (TX Matrix routers only) (Optional) Display logging information for the TX Matrix router (or switch-card chassis).
sfc — (TX Matrix Plus routers only) (Optional) Display logging information for the TX Matrix Plus router (or switch-fabric chassis).
core-filename — (Optional) Name of a specific core file to display.
core-file-info — (Optional) Display the stack trace of a core file.
brief — (Optional) View details of binary.
detail — (Optional) View stack trace with details of binary.
