by the hello time parameter to check for link failures. Normally, a switch regards its
upstream switch faulty if the former does not receive any BPDU from the latter in a
period three times of the hello time and then initiates the spanning tree recalculation
process.
Spanning trees may be recalculated 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 such cases. 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.

1.3.11 Configuring the Maximum Transmitting Rate on the Current Port
The maximum transmitting rate 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.
