Step
3. Configure the port
priority.

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. HP recommends you to use the default setting and let the device to
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 the physical link to which the port connects is not a point-to-point link but you set it to be one, the
•
configuration might bring a temporary loop.

Configuration procedure

To configure the link type of a port or a group of ports:
Step
1. Enter system view.
2. Enter interface view or
port group view.
3. Configure the port link
type.
Configuring the mode a port uses to
recognize/send MSTP packets
A port can receive/send MSTP packets in the following formats:
• dot1s—802.1s-compliant standard format
Command
•
In STP/RSTP mode:
stp port priority priority
•
In PVST mode:
stp vlan vlan-list port priority priority
•
In MSTP mode:
stp [ instance instance-id ] port priority priority
Command
system-view
•
Enter Layer 2 Ethernet interface view or Layer
2 aggregate interface view:
interface interface-type interface-number
•
Enter port group view:
port-group manual port-group-name
stp point-to-point { auto | force-false |
force-true }

commands.
The default setting is
128.
Remarks
N/A
Use one of the
