F5 Clear Front Panel LCD display warnings remotely

F5 appliance LCD warning displays cannot be seen remotely, neither LED alarms. But if you would like to remotely see any warnings, these are written in /var/log/ltm file.

However you can remotely clear LCD warnings and Alarm LED using following commands.

Note: Performing following procedure should not have a negative impact on the appliance.

lcdwarn -c <level> <slotid>

In this command syntax, note the following:

<level> specifies the alert level to be cleared, specify either [0|1|2|3|4|5] or [warning|error|alert|critical|emergency|information]

<slotid>, leave as 0 for non-VIPRION platform.

For example,
