Neighbor Discovery States
Ready
The neighbor discovery module is in a “Ready” state when it is not scanning for other units.
If the Viper is operating in Manual-Scan, it does nothing.
If the Viper is operating in Auto-Scan, it monitors the “keep alive” packets of other units
and sends its own “keep alive” packet periodically.
Scanning For Neighbors
The neighbor discovery module is trying to learn about other units. Other units are learning
about this unit.
Saving Neighbor Table
In this state, the Viper is saving all neighbor entries of type "Dynamic" into
Nvram. When the save is complete, all these entries are now of type "Locked".
This state only occurs when the neighbor discovery module operates in
Manual-Scan mode.
Testing Connectivity
The neighbor discovery module is verifying the Viper units in the neighbor table are
reachable by sending them an alive-request and waiting for an alive-response. Round trip
time must not exceed 10 seconds. The alive-request is only sent once.
