1.2.10 Timeout Time Factor Configuration
A switch regularly sends protocol packets to its neighboring devices at the interval
specified by the Hello time parameter to test the links. Normally, a switch regards its
upstream switch faulty if the former does not receive any protocol packets from the
latter in a period three times of the Hello time and then initiates the spanning tree
regeneration process.
Spanning trees may be regenerated even in a steady network if an upstream switch
continues to be busy. You can configure the timeout time factor to a larger number to
avoid this. Normally, the timeout time can be four or more times of the Hello time. For a
steady network, the timeout time can be five to seven times of the Hello time.

1.2.11 Maximum Transmitting Speed Configuration
The maximum transmitting speed of a port specifies the maximum number of
configuration BPDUs a port can transmit in a period specified by the Hello time
parameter. It depends on the physical state of the port and network structure. You can
configure this parameter according to the network.
