Applicable Environment
On some specific networks, proper RSTP parameter settings will help implement rapid network
convergence.
NOTE
The default configurations for the parameters described in this section help implement RSTP rapid
convergence. Therefore, the configuration process and all involved procedures described in this section
are optional.
Pre-configuration Tasks
Before configuring STP/RSTP parameters, complete the following task:
l
Configuring basic STP/RSTP functions
Data Preparation
To configure STP/RSTP parameters, you need the following data.
No.
Data
1
Network diameter
2
Hello timer, Forward Delay timer, Max Age timer, and timeout period for waiting
for BPDUs from the upstream (3 x Hello timer value x Time factor)
3
Link type of a port
4
Whether a port is enabled with rapid transition mechanism
5
Whether a port needs to transition to the RSTP mode
6
Maximum number of sent BPDUs
7
Whether a port needs to be configured as an edge port
8
Whether auto recovery needs to be configured for an edge port being shut down
9
Whether a port needs to clear statistics of the spanning tree
10
Whether the edge port needs to be configured as a BPDU filter
7.4.2 Configuring System Parameters
STP/RSTP 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). Therefore, STP/RSTP parameters must be set properly to help implement
rapid network convergence.
