To do...
Configure the timeout factor
of the device
Timeout time = timeout factor × 3 × hello time.
■
Typically, we recommend that you set the timeout factor to 5, or 6, or 7 for a
■
stable network.
Configuration example
# Set the timeout factor to 6.
<Sysname> system-view
[Sysname] stp timer-factor 6
The maximum transmission rate of a port refers to the maximum number of MSTP
packets that the port can send within each hello time.
The maximum transmission rate of an Ethernet port is related to the physical
status of the port and the network structure.
Configuration procedure
Following these steps to configure the maximum transmission rate of a port or a
group of ports:
To do...
Enter system view
Enter Ethernet Enter Ethernet
interface view interface view
or port group
Enter port
view
group view
Configure the maximum
transmission rate of the port(s)
If the maximum transmission rate setting of a port is too big, the port will send
■
a large number of MSTP packets within each hello time, thus using excessive
network resources. We recommend that you use the default setting.
Refer to "Aggregation Port Group" on page 349

Configuration example
# Set the maximum transmission rate of port Ethernet 1/0 to 5.

Configured in Ethernet
interface view, the setting is
effective on the current port
only; configured in port
group view, the setting is
effective on all ports in the
