Core and Log Files
Figure 68-3 Show Cores Dialog Box
Module-num shows the slot number on which the core was generated. In this example, the fspf core was
generated on the active supervisor module (slot 5), fcc was generated on the standby supervisor module
(slot 6), and acltcam and fib were generated on the switching module (slot 8).
Step 2 Click Close to close the dialog box.
Clearing the Core Directory
Note Be sure SSH2 is enabled on this switch.
To clear the cores on a switch using Device Manager, follow these steps:
Step 1 Click Clear to clear the cores.
The software keeps the last few cores per service and per slot and clears all other cores present on the
active supervisor module.
Step 2 Click Close to close the dialog box.
First and Last Core
The first and last core feature uses the limited system resource and retains the most important core files.
Generally, the first core and the most recently generated core have the information for debugging and,
the first and last core feature tries to retain the first and the last core information.
If the core files are generated from active supervisor module, the number of core files for the service is
defined in the service.conf file. There is no upper limit on the total number of core files in the active
supervisor module.
