According to 
https://portal.nutanix.com/page/documents/kbs/details?targetId=kA0600000008T3jCAE
 :
'The lanplus parameter is required to enable the IPMI 2.0 RMPC+ protocol'

According to 
https://en.wikipedia.org/wiki/Intelligent_Platform_Management_Interface 'RMCP+ 
(a UDP-based protocol with stronger authentication than RMCP) is used for IPMI 
over LAN.'


I guess you can find more details at 
https://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/ipmi-second-gen-interface-spec-v2-rev1-1.pdf
 (page 129,130).

Thank you very much!
I have read your document. The article mentioned that LANPLUS enhances the 
security of communication, but it did not elaborate on what LANPLUS is. 
I want to know what technology it is.

True or 1. If blank, then value is False. It is recommended that you enable 
Lanplus to improve the security of your connection if your hardware supports it.
 
Most probably the hardware doesn't support with reduced security (lanplus=False 
is the default).
