GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches

For more information, see CST Configuration on page 94.

5.In the CST Port Configuration screen, select ports g1–g8 and select Enable from the STP Status list.

For more information, see CST Port Configuration on page 96.

6.Click APPLY.

7.Select ports g1–g5 (edge ports), and select Enable from the Fast Link list.

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

8.Click APPLY.

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

9.In the MST Configuration screen, create an MST instance with the following settings:

•MST ID. 1

•Priority. Use the default (32768)

•VLAN ID. 300

For more information, see MST Configuration on page 99.

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 Human Resources department (ports g4 and g5). Switches 1 and 2 also have hosts in the Sales and HR 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.
