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.
Configuration procedure
For a steady network, the timeout time can be five to seven times of the hello
time.
Configuration example
# Configure the timeout time factor to be 6.

Configuring the
Maximum Transmitting
Speed on the Current
Port
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.
Configure the maximum transmitting speed for specified ports in system
view
Configure the maximum transmitting speed in Ethernet port view
As the maximum transmitting speed parameter determines the number of the
configuration BPDUs transmitted in each hello time, set it to a proper value to
