What is swL3RelayDhcpOption82CheckState?
Read-write toggle (disabled(0)/enabled(1)) controlling whether the switch validates the Option 82 field on DHCP replies coming back from the server before relaying them to the client. Admins enable it as a security check to reject DHCP replies whose Option 82 data doesn't match what the switch expects, guarding against spoofed DHCP server responses.
