Viewing and configuring port instance details

Use the Port Instance tab to view and configure MST parameters per port per instance, including
Port Priority and Admin Internal Path Cost.
To view and configure the MSTP bridge instance:
1. Select Network > Multiple Spanning Tree from the main menu tree.
2. Select the PortInstance tab.

Port Guard Root
Port Guard Root Select this checkbox to enable guard root for this port. Typically,
each guard root port is a designated port, unless two or more ports (within the root
bridge) are connected together. If the bridge receives superior (BPDUs) on a guard
root-enabled port, the guard root moves the port to a root-inconsistent STP state.
This state is equivalent to a listening state. No data is forwarded across the port.
Thus, the guard root enforces the root bridge position.
PortFast BPDU Filter Enable this option to change the status of the Port Fast BPDU Filter.
Port FastBPDU Guard Enable this option to change the status of the Port Fast BPDU Guard.
Port Version Select a value to reconfigure the port version.
Port Path Cost Port Path Cost Displays the path cost for the specified port index. The default path
cost depends on the speed of the interface.

Admin Point-to-Point
Define the point-to-point status as ForceTrue or ForceFalse. ForceTrue indicates
status this port should be treated as connected to a point-to-point link. ForceFalse
indicates this port should be treated as having a shared connection. A port
connected to a hub is on a shared link, while one connected to a controller or
workstation is a point-to-point link.
Port Enable
Select this checkbox to use this port for the forwarding of packets on the controller.
Port Migration
The controller can interoperate with legacy 802.1d bridges running STP / RSTP. If
the port receives a legacy 802.1D configuration BPDU, it only sends 802.1D
BPDUs over its port from that point on. Enable this option to restart detection of
whether the port is connected to an MSTP capable bridge or a legacy 802.1 bridge.
Admin Edge Port
Select the checkbox to define this port as an admin edge port.
