Configuring The Port Link Type; Configuration Restrictions And Guidelines; Configuration Procedure - HP 6125XLG Configuration Manual

On a spanning tree device, a port can have different priorities and play different roles in different
spanning trees. As a result, data of different VLANs can be propagated along different physical paths,
implementing per-VLAN load balancing. You can set port priority values based on the actual networking
requirements.
When the priority of a port changes, the system re-calculates the port role and initiates a state transition.
To configure the priority of a port:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet or
aggregate interface view.
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 that you use the default setting and letting the device
automatically detect the port link type.
In MSTP or PVST mode, the stp point-to-point force-false or stp point-to-point force-true command
•
configured on a port 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.
