1.2.9 Set Timeout Factor of the Bridge

A bridge transmits hello packet regularly to the adjacent bridges to check if there is link
failure. Generally, if the switch doesn't receive the RSTP packets from the upstream
switch for 3 times of hello time, the switch will decide the upstream switch is dead and
will recalculate the topology of the network. Then in steady network, the recalculation
may be caused when the upstream is busy. In this case, user can redefine the timeout
interval to a longer time by define the multiple of hello time.
You can use the following command to set the multiple value of hello time of a specified
bridge.
Perform the following configurations in system view.
Table1-9 Set Timeout Factor of the Bridge
Set the multiple value of hello time of a specified bridge
Restore the default multiple value of hello time
It is recommended to set 5, 6 or 7 as the value of multiple in the steady network.
By default, the multiple value of hello time of the bridge is 3.

1.2.10 Set the Maximum Transmission Speed of the Specified Port

The maximum transmission speed of Ethernet port is related to its physical state and
network structure. Users can configure it according to the actual network situation.
You can use the following command to set the maximum transmission speed of the
specified port.
Perform the following configurations in Ethernet port view.
Table1-10 Set the maximum transmission speed of the specified port
Set the maximum transmission speed of the specified port
Restore the default maximum transmission speed of the
specified port
If the max transmission speed on a port is too high, there will be too many packets
being transmitted per unit time, which occupies excessive network resources. It is
recommended to use the default setting.
