R21xx-HP FlexFabric 11900 Layer 2 LAN Switching Command Reference

130
Parameters
auto: Specifies automatic detection of the link type.
force-false: Specifies the non-point-to-point link type.
force-true: Specifies the point-to-point link type.
Usage guidelines
When connecting to a non-point-to-point link, a port is incapable of rapid state transition.
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, which lets 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
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 cause a temporary loop.
When the setting is configured in Layer 2 Ethernet interface view, it takes effect only on that interface.
When the setting is configured in Layer 2 aggregate interface view, it takes effect only on the aggregate
interface.
When the setting is configured on a member port in an aggregation group, it takes effect only after the
port leaves the aggregation group.
Examples
# Configure the link that connects Ten-GigabitEthernet 1/0/3 as a point-to-point link.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/3
[Sysname-Ten-GigabitEthernet1/0/3] stp point-to-point force-true

tree.
Use undo stp port priority to restore the default.
Syntax
stp [ instance instance-list ] port priority priority
undo stp [ instance instance-list ] port priority
Default
The port priority is 128.
