Mstp Example - Accton Technology ES4626 Management Manual

Function: Set the current port as boundary port; The command "no spanning-tree
portfast" sets the current port as non-boundary port.
Command mode: Interface Mode
Default: All the ports are non-boundary ports by default when enabling MSTP.
Usage Guide: When a port is set to be a boundary port, the port converts its status from
discarding to forwarding without bearing forward delay. Once the boundary port receives
the BPDU, the port becomes a non-boundary port.
Example: Set port 1/5-6 as boundary ports.
Switch(Config)#interface ethernet 1/5-6
Switch(Config-Port-Range)#spanning-tree portfast

6.3 MSTP Example

The following is a typical MSTP application scenario:

The connections among the switches are shown in the above figure. All the switches
run in the MSTP mode by default, their bridge priority, port priority and port route cost are
all in the default values (equal). The default configuration for switches is listed below:
