NETGEAR GS108Tv3 User Manual

8-Port Gigabit (PoE+) Ethernet Smart Managed Pro Switch with (2 SFP or 2 Copper Ports and)
Cloud Management
Configuration Examples User Manual477
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 180).
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 182).
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.
You can use the CST Port Status page to view spanning tree information about each
port.
9. On the MST Configuration page, 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 187.
10. Click the Add button.
11. Create a second MST instance with the following settings
• MST ID. 2
• Priority. 49152
• VLAN ID. 500
12. Click the Add button.
In this example, assume that Switch 1 became the root bridge for the MST instance 1, and
Switch 2 became the root bridge for MST instance 2. Switch 3 supports hosts in the sales
department (ports 1/0/1, 1/0/2, and 1/0/3) and in the HR department (ports 1/0/4 and 1/0/5).
Switches 1 and 2 also include 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.
VLAN routing interfaces
VLANs divide broadcast domains in a LAN environment. When hosts in one VLAN must
communicate with hosts in another VLAN, the traffic must be routed between them. This is
known as inter-VLAN routing. On the switch, it is accomplished by creating Layer 3 interfaces
(switch virtual interfaces [SVI]).
