AeroLink Protection Status (For Client/Slave Mode Only) 
After you have enabled AeroLink Protection in the Advanced WLAN Setup panel, the current state of the 
AeroLink Protection is displayed here for easy diagnosis. 
A member of the AeroLink Protection group can take one of the following seven states: 
•  Initiation State (Init): Initiates the AeroLink Protection Protocol 
•  Discovering State (Discover): Discovers other AeroLink Protection members for further negotiation 
•  Idle State (Idle): Internal protocol checkpoint 
•  Negotiation State (Nego): Negotiates with other AeroLink Protection members and elects an Active 
node. 
•  Backup State (Backup): After negotiation, this node is assigned as a Backup node. All traffic will go 
through the Active node instead. 
NOTE 
When a node is in Backup state, the STATE LED will be blinking. 
•  Active State (Active): After negotiation, this node is assigned as Active node, which means that all traffic 
will go through this node. 
•  Role Change State (Change): If the Active node is no longer capable of data transmission via the WLAN, 
it will turn into Change State to trigger the re-negotiation of the Active node from the Backup nodes.
