Since the edge ports are not at risk for network loops, ports with Fast Link enabled 
transition directly to the Forwarding state.

You can use the CST Port Status screen to view spanning tree information about each 
port.

From the MST Configuration screen, create a MST instances with the following settings:
•     
MST ID: 1
•     
Priority: Use the default (32768)
•     
VLAN ID: 300
10. 
Click Add.
11. 
Create a second MST instance with the following settings
•     
MST ID: 2
•     
Priority: 49152
•     
VLAN ID: 500
12. 
Click Add.
In this example, assume that Switch 1 has become the Root bridge for the MST instance 1, 
and Switch 2 has become the Root bridge for MST instance 2. Switch 3 has hosts in the 
Sales department (ports g1, g2, and g3) and in the HR department (ports g4 and g5). 
Switches 1 and 2 also have hosts in the Sales and Human Resources departments. The 
hosts connected from Switch
 
2 use VLAN 500, MST instance 2 to communicate with the 
hosts on Switch 3 directly. Likewise, hosts of Switch 1 use VLAN 300, MST instance 1 to 
communicate with the hosts on Switch 3 directly.
The hosts use different instances of MSTP to effectively use the links across the switch. The 
same concept can be extended to other switches and more instances of MSTP.
