Configure Switching

S350 Series 8-Port Gigabit Ethernet Smart Managed Pro Switch Models GS308T and GS310TP
6. Configure the MST values:
• MST ID. Specify the ID of the MST to create.
The range is from 1 to 4094. This is
visible only when the select option of the MST ID select box is selected.
• Priority.
The bridge priority value for the MST. When switches or bridges are running
STP, each is assigned a priority. After exchanging BPDUs, the switch with the lowest
priority value becomes the root bridge. The bridge priority is a multiple of 4096. If you
specify a priority that is not a multiple of 4096, the priority is automatically set to the
next lowest priority that is a multiple of 4096. For example, if you set the priority to any
value between 0 and 4095, the switch automatically sets the value to 0. The default
value is 32768. The range is from 0 to 61440.
• VLAN Id.
The menu includes all VLANs that are configured on the switch. You can
select VLANs that must be associated with the MST instance or clear VLANs that are
already associated with the MST instance.
7. Click the Add button.
The MST is added.
For each configured instance, the information described in the following table displays on the
page.
Table 31. MST configuration
Field Description
Bridge Identifier The bridge identifier for the selected MST instance. It is made up using the bridge
priority and the base MAC address of the bridge.
Last TCN The time in the format “day:hour:minute:second” since the topology of the selected
MST instance last changed.
Topology Change Count The number of times that the topology changed for the selected MST instance.
Topology Change The value of the topology change settings for the switch, indicating if a topology
change is in progress on any port assigned to the selected MST instance. It is either
T
rue or False.
Designated Root The bridge identifier of the root bridge. It is made up from the bridge priority and the
base MAC address of the bridge
Root Path Cost The path cost to the designated root for this MST instance.
Root Port The port to access the designated root for this MST instance.
Modify an MST Instance
To modify an MST instance:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is of
f-network using an Ethernet cable.
2. Launch a web browser.
