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 module
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.
For the BlackDiamond Switches. There are three ways to clear the ERR LED on the MSM for the
BlackDiamond switches: 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:
diag-status Clears the hardware error code.
error-led Clears the ERR LED on the MSM.
NOTE: This option is supported only on the BlackDiamond switches.
static Specifies that the messages in the NVRAM target are cleared, and the ERR LED on the MSM
is cleared (on platforms with the MSM).
memory-buffer Clears entries from the memory buffer.
nvram Clears entries from NVRAM
