24-Port Gigabit (Hi-Power) PoE+ Ethernet Smart Managed Pro Switch with 2 SFP Ports
Configuration Examples User Manual418
Perform the following procedures on each switch to configure MSTP:
1. On the VLAN Configuration page, create VLANs 300 and 500 (see Configure VLAN
settings on page 141).
2. On the VLAN Membership page, include ports 1/0/1–1/0/8 as tagged (T) or untagged (U)
members
of VLAN 300 and VLAN 500 (see
Configure VLAN settings on page 141).
3. On the STP Configuration page, enable the Spanning Tree State option (see
Configure the
STP settings and view the STP status on page 161).
Use the default values for the rest of the STP configuration settings. By default, the STP
operation mode is MSTP and the configuration name is the switch MAC address.
4. On the CST Configuration page (see
Configure the CST port settings on page 165), set
the bridge priority value for each of the three switch connections to
force Switch 1 to be the
root bridge:
• Connection to Switch 1. 4096
• Connection to Switch 2. 12288
• Connection to Switch 3. 20480
Note: Bridge priority values are multiples of 4096.
If you do not specify a root bridge and all switches are assigned the same bridge priority
value, the switch with the lowest MAC address is elected as the root bridge (see
Configure the CST settings on page 163).
5. On the CST Port Configuration page, select ports 1/0/1–1/0/8 and select Enable
from the
STP Status menu (see
Configure the CST port settings on page 165).
6. Click the Apply button.
7. Select ports 1/0/1–1/0/5 (edge ports), and select Enable
from the Fast Link menu.
Since the edge ports are not at risk for network loops, ports with Fast Link enabled
transition directly to the forwarding state.
8. Click the Apply button.
On the CST Port Status page you can view spanning tree informat
ion about each port.
9. On the MST Configuration page (see
Manage the MST settings on page 170), create a
MST instances with the following settings:
• MST ID. 1
• Priority. Use the default (32768)
• VLAN ID. 300
For more information, see
View the Rapid STP information on page 169.
10. Click the Add
button.
11. Create a second MST instance with the following settings
•
MST ID. 2
• Priority. 49152
• VLAN ID. 500
