Commands for Status Monitoring and Statistics
clear log
clear log {diag-status | error-led | static | messages [memory-buffer |
nvram]}
Description
Clears the log database.
Syntax Description
Default
N/A.
Usage Guidelines
The switch log tracks configuration and fault information pertaining to the device.
By default, log entries that are sent to the NVRAM remain in the log after a switch reboot. The
clear
log
and
clear log messages memory-buffer
commands remove entries in the memory buffer target;
the
clear log static
and
clear log messages nvram
commands remove messages from the
NVRAM target as well as the memory buffer target.
When there is a hardware failure, a hardware error code might be saved to the FLASH or NVRAM
(depending on the switch configuration). Upon reboot, the switch will not try to bring up a card with
an error code, so it will be shown in a failed state. Use the
clear log diag-status
command to clear
the hardware error code, so the module can be brought up after the next reboot. This command clears
the state for all the modules.
There are three ways to clear the ERR LED. Clear the log, reboot the switch, or use the
clear log
error-led
command. To clear the ERR LED without rebooting the switch or clearing the log messages,
use the
clear log error-led
command.
Example
The following command clears all log messages, from the NVRAM:
clear log static
