Among aggregated ports, you can only configure the links of master ports as point-to-point links. If an auto-negotiating port operates in full duplex mode after negotiation, you can configure the link of the port as a point-to-point link.

After you configure the link of a port as a point-to-point link, the configuration applies to all the spanning tree instances the port belongs to. If the actual physical link of a port is not a point-to-point link and you forcibly configure the link as a point-to-point link, loops may occur temporarily.

Configuration example

# Configure the link connected to GigabitEthernet 1/0/1 as a point-to-point link.

1)Perform this configuration in system view

<device> system-view

[device] stp interface GigabitEthernet1/0/1 point-to-point force-true

2)Perform this configuration in Ethernet port view

<device> system-view

[device] interface GigabitEthernet1/0/1

[device-GigabitEthernet1/0/1] stp point-to-point force-true

Enabling MSTP
