Figure 3-6 Configure MSTP Function Globally
Follow these steps to configure MSTP globally:
1) In the Parameters Config section, Configure the global parameters of MSTP and click
Apply.
CIST Priority
Hello Time
Max Age
Specify the CIST priority for the switch. CIST priority is a parameter used to
determine the root bridge for spanning tree. The switch with the lower value
has the higher priority.
In STP/RSTP, CIST priority is the priority of the switch in spanning tree. The
switch with the highest priority will be elected as the root bridge.
In MSTP, CISP priority is the priority of the switch in CIST. The switch with the
higher priority will be elected as the root bridge in CIST.
Specify the interval between BPDUs' sending. The default value is 2. The root
bridge sends configuration BPDUs at an interval of Hello Time. It works with
the MAX Age to test the link failures and maintain the spanning tree.
Specify the maximum time that the switch can wait without receiving a BPDU
before attempting to regenerate a new spanning tree. The default calue is
20.
