Port Parameters

In this interface, you can modify and query port parameters.

Navigation Path

In the NE Explorer, select the board and choose Configuration > Layer-2 Switching Management > Multiple Spanning Tree, click the Bridge Parameters tab. Click the Port Parameters in the lower pane.

Buttons

Button	Description
Protocol Transfer	In a switching network, a port on the switch with the MSTP protocol is connected to the switch with the STP protocol. The port can automatically transfer to and work in the STP-compatible mode. If the switch with the STP protocol is disconnected, the port does not automatically transfer to the MSTP mode and still works in the STP-compatible mode. In this case, perform the protocol transfer function to transfer the port to the MSTP mode.

Protocol Transfer

In a switching network, a port on the switch with the MSTP protocol is connected to the switch with the STP protocol. The port can automatically transfer to and work in the STP-compatible mode.

In this case, perform the protocol transfer function to transfer the port to the MSTP mode.

Parameters

Field	Value	Description
Port	Equipment that supports the master and slave shelf management: shelf ID(shelf name)-slot number-board name-port number(port name) Equipment that does not support the master and slave shelf management: slot number-board name-port number(port name)	Displays the port.
Enable Edge Attribute	Disabled, Enabled	Displays and sets the edge attribute. The edge port indicates the port that is neither directly connected to any switch nor indirectly connected to any switch through the network in connection to the port. If the user specifies a port as the edge port when the port transfers from the congestion status to the forwarding status, the edge port can quickly migrate without the wait of the delay. The user can specify the port connected to the terminal as the edge port.
Actual Edge Attribute	Disabled, Enabled	Display the actual edge attribute.
Point-to-Point Attribute	auto, false, true	Display and set the point-to-point attribute. auto: point-to-point link attributes or non-point-to-point link attributes, as detected false: non-point-to-point link attributes true: point-to-point link attributes The point-to-point link is the direct link between two switches. If a port is connected to a point-to-point link or any other link, the connection of the port is set accordingly on all spanning tree instances. If the physical link connected to a port is not a point-to-point link, incorrect configuration of the link as a point-to-point link may introduce temporary path loop.
Actual Point-to-Point Attribute	false, true	true: point-to-point link false: non-point-to-point (Shared Link)
