What are the essential tmsh commands for managing an F5 BIG-IP system during vulnerability research?

Essential tmsh commands include checking the version with `tmsh show /sys version`, viewing all configurations via `tmsh -c 'list all-properties'`, and managing users with `tmsh create auth user` or `tmsh delete auth user`. For firewall rule inspection, use `tmsh -c 'list /security firewall management-ip-rules'`. Detailed tmsh references are available in the F5 BIG-IP Vulnerability Debugging Environment Setup.
