3. Configure the port priority.
• In STP/RSTP mode:
stp port priority priority
• In PVST mode:
stp vlan vlan-id-list port priority

• In MSTP mode:
stp [ instance instance-list ] port
priority priority
The default setting is 128
for all ports.
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
• You can configure the link type as point-to-point for a Layer 2 aggregate interface or a port that
operates in full duplex mode. As a best practice, use the default setting and let the device
automatically detect the port link type.
• The stp point-to-point force-false or stp point-to-point force-true command configured on a
port in MSTP or PVST mode takes effect on all MSTIs or VLANs.
• If you configure a non-point-to-point link as a point-to-point link, a temporary loop might occur.

detects the link type.
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
