TP-Link TL-SL3452, TL-SL3428 Modify the Port Priority and Path Cost, MSTP Interface Settings Page

The possible field values are:

–Root — Provides the lowest cost path to forward packets to the root device.

–Designated — Indicates the port or LAG through which the designated device is attached to the LAN.

–Alternate — Provides an alternate path to the root device from the root interface.

–Backup — Provides a backup path to the designated port path toward the Spanning Tree leaves. Backup ports occur only when two ports are connected in a loop by a point-to-point link or when a LAN has two or more connections connected to a shared segment.

–Disabled — Indicates the port is not participating in the Spanning Tree.

Mode — Indicates the STP mode by which STP is enabled on the device. The possible field values are:

–Classic STP — Classic STP is enabled on the device. This is the default value.

–Rapid STP — Rapid STP is enabled on the device.

–Multiple STP — Multiple STP is enabled on the device.

Type — Indicates whether the port is a Boundary or Master port. The possible field values are:

–Boundary Port — Indicates that the port is a Boundary port. A Boundary port attaches MST bridges to LANs in an outlying region. If the port is a Boundary port, this field also indicates whether the device on the other side of the link is working in RSTP or STP mode

–Master Port — Indicates the port is a master port. A Master port provides connectivity from a MSTP region to the outlying CIST root.

Interface Priority — Defines the Interface priority for the specified instance. The default value is 128.

Path Cost — Indicates the port contribution to the Spanning Tree instance. The range should always be 1-200,000,000.

Port State — Indicates whether the port is enabled for the specific instance. The possible field values are:

–Enabled — Enables the port for the specific instance.

–Disabled — Disables the port for the specific instance.

Designated Cost — Indicates that the default path cost is assigned according to the method selected on the Spanning Tree Global Settings page.

Designated Bridge ID — Displays the ID of the bridge that connects the link or shared LAN to the root.

Designated Port ID — Displays the ID of the port on the designated bridge that connects the link or the shared LAN to the root.

Remain Hops — Indicates the hops remaining to the next destination.
