Port Settings

Port settings displays port or instance level details. You can configure parameters such as port priority, path cost, and the option to enable or disable Spanning Tree Protocol (STP) for a specific port.

View by Port :

Instance	Displays instance number
VLAN Range	Displays the VLAN range on a switch, which is added when creating an MST instance.
Enable (STP Configuration)	Enable or disable the STP for each specific port. Enabling STP helps prevent loops in network topology while disabling it might be necessary for certain topologies or for specific configurations where loop prevention is managed differently.
Port Priority	Determines the priority level of a port compared to others. Higher-priority ports are favored during the spanning tree process, which prevents network loops.
Internal Path Cost Conf	Path cost refers to the value assigned to a port that indicates the expense of using that port to reach a destination. In the spanning tree algorithm, lower path costs are prioritized, ensuring efficient traffic routing.

Regional Root Bridge	Refers to a switch designated as the primary point for Spanning Tree Protocol (STP) calculations within a specific network segment.
Internal Root Cost	Refers to the calculated cost of the path from a switch to its designated Root Bridge.
Designated Bridge	Refers to the switch that is designated as the primary forwarding point for a specific network segment.
Port Role	Refers to the role of a switch port within the STP topology, such as Root Port or Designated Port.
Port State	Refers to the operational status of a switch port (like forwarding or blocking) based on its role in the Spanning Tree protocol.
