Hi Somchai
I appreciate your thought cast as technical support.
This case is a balance between EAP320 promotion and EAP320 technical principle,
regardless of promotion purpose, my opinion is the same with our RD team, the LAG
can not help to in create the speed of transmission, but backup or load balance are fact.
As Nok asked me earlier that "is there a way to verify the aggregated bandwidth of
EAP330", I designed a test topology as shown in the attachment, hope you can understand.
