Select the P2P link status. If the two ports in the P2P link are root port or designated port, they can transit their states to forwarding rapidly to reduce the unnecessary forward delay. 0. auto 1. force enable 2. force disable Enumeration: 'auto': 0, 'force-disable': 2, 'force-enable': 1.

Select Enable to perform MCheck operation on the port. Unchange means no MCheck operation. 0. unChange 1. enable Enumeration: 'enable': 1, 'unChange': 0.

Displays the STP version of the port. 1. stp 2. rstp 3. mstp Enumeration: 'mstp': 3, 'stp': 1, 'rstp': 2, 'n-a': 0.

Displays the role of the port played in the STP Instance. 1.Disable:Indicates the port that is not participating in the STP. 2.Alternate:Indicates the port that can be a backup port of a root or master port. 3.Backup:Indicates the port that is the backup port of a designated port. 4.Designated:Indicates the port that forwards packets to a downstream network segment or switch. 5.root:Indicates the port that has the lowest path cost from this bridge to the Root Bridge and forwards packets to the root. 6.Master:Indicates the port that connects a MST region to the common root. The path from the master port to the common root is the shortest path between this MST region and the common root. Enumeration: 'root': 5, 'alternate': 2, 'designated': 4, 'disabled': 1, 'master': 6, 'n-a': 0, 'backup': 3.

Displays the working status of the port. 1.Disconnected: In this status the port is not participating in the STP. 2.Blocking: In this status the port can only receive BPDU packets. 3.Learning: In this status the port can receive/send BPDU packets and learn MAC address. 4.Forwarding: In this status the port can receive/forward data, receive/send BPDU packets as well as learn MAC address. Enumeration: 'learning': 3, 'forwarding': 4, 'disconnected': 1, 'blocking': 2, 'n-a': 0.

Displays the LAG number which the port belongs to.

Displays Instance ID of the switch,0 representative CIST.

Displays status of the instance. 0. Disable 1. Enable Enumeration: 'enable': 1, 'disable': 0.

Enter the priority of the switch in the instance. It is an important criterion on determining if the switch will be chosen as the root bridge in the specific instance.Make sure that Priority ranges from 0 to 61440 and could be divided exactly by 4096

Enter the desired VLAN ID. After modification here, the new VLAN ID will be added to the corresponding instance ID and the previous VLAN ID won't be replaced.The format of input VLAN ID shoud be like '1,3,4-7,11-30' in the range from 1 to 4094.

This object use to clear instance's vlan id.The cleared VLAN ID will be automatically mapped to the CIST. Enumeration: 'clear': 1.

A port can play different roles in different spanning tree instance. Here you can configure the parameters of the ports in different instance IDs as well as view status of the ports in the specified instance.

An entry contains of the mstp instance port config.

The instance ID for its port configuration, 1-8.
