RE: FW: EPON MIB comments (eponDeviceRemoteMACAddressLLIDControl)

Lior,

Please clean up the grammar of this DESCRIPTION clause, otherwise it is hard to understand. Expressions like 'a table of read-only value that identifies...' or 'the table is defined as Remote MAC Address...' do not make too much sense to me. I can guess that you are referring to the objects (columns) in the table, but I will leave to you clarifying this text. 

Regards,

Dan
