PPP: Detect connection with PPP method, when choose this method, users should also

configure "Detection Interval" item.

Detection Interval: time interval between two detections, unit is second
Primary Detection Server IP: the server used to response the router’s detection packet. This item

is only valid for method "Ping" and "Route".
Backup Detection Server IP: the server used to response the router’s detection packet. This item
is valid for method "Ping" and "Route".

Note: When users choose the “Route” or “Ping” method, it’s quite important to make sure

that the “Primary Detection Server IP” and “Backup Detection Server IP” are usable and stable,

because they have to response the detection packet frequently.

Force reconnect: this option schedules the pppoe or 3G reconnection by killing the pppd daemon
and restart it.

Time: needed time to reconnect

STP

STP (Spaning Tree Protocol) can be applied to loop network. Through certain algorithm achieves
path redundancy, and loop network cuts to tree-based network without loop in the meantime, thus
to avoid the hyperplasia and infinite circulation of a message in the loop network
