8.4.2 Configuring System Parameters
MSTP parameters that may affect network convergence include the network diameter, Hello
timer, and timeout period for waiting for BPDUs from the upstream device (3 x Hello timer
value x Time factor). Proper MSTP parameter settings help implement rapid network
convergence.
Procedure
Step 1
Run:
system-view
The system view is displayed.
Step 2
Run:
stp bridge-diameter
diameter
The network diameter is configured.
By default, the network diameter is 7.
l
RSTP uses a single spanning tree instance on the entire network. As a result, performance
deterioration cannot be prevented when the network scale grows. Therefore, the network
diameter cannot be larger than 7.
l
It is recommended that you run the
stp bridge-diameter
diameter
command to set the
network diameter. Then, the switching device calculates the optimal Forward Delay period,
Hello timer value, and Max Age timer value based on the set network diameter.
Step 3
Run:
stp timer-factor
factor
The timeout period for waiting for BPDUs from the upstream device is set.
By default, the timeout period is 9 times the Hello timer value.
Step 4
(Optional) If the current device is at the edge of a network, run both or either of the following
commands as needed:
l
To configure all ports on the devices as edge ports, run:
stp edged-port default
By default, a port is a non-edge port.
After ports on a network edge device are configured as edge ports, the ports no longer
participate in spanning tree calculation. This speeds up network topology convergence and
improves network stability.
