Configuring the port link type
A point-to-point link directly connects two devices. If two root ports or designated ports are connected
over a point-to-point link, they can rapidly transit to the forwarding state after a proposal-agreement
handshake process.
Configuration restrictions and guidelines
• In PVST or MSTP mode, the stp point-to-point force-false or stp point-to-point force-true command
configured on a port takes effect on all VLANs or all MSTIs.
• If you configure a non-point-to-point link as a point-to-point link, a temporary loop might occur.
Configuration procedure
To configure the link type of a port:

Configuring the mode a port uses to recognize and
send MSTP packets
A port can receive and send MSTP packets in the following formats:
• dot1s—802.1s-compliant standard format
• legacy—Compatible format
