1-26 

2: System level 

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.  

Use the stp point-to-point command to specify whether the current port(s) is/are connected to a 

point-to-point link or point-to-point links.  

Use the undo stp point-to-point command to restore the system default.  

The default setting is auto; namely the MSTP-enabled device automatically detects whether an 

Ethernet port connects to a point-to-point link.  

Note that: 

z 

Configured in port view, the setting takes effect on the current port only; configured in port group 

view, the setting takes effect on all ports in the port group.  

z 

Configured in Layer-2 aggregate port view, the setting takes effect only on the aggregate port. 

Configured on the member port in an aggregation group, the setting can take effect only after the 

port leaves the aggregation group. For detailed information about link aggregation, refer to Link 

Aggregation Configuration in the Access Volume.  

z 

When connecting to a non-point-to-point link, a port is incapable of rapid state transition.  

z 

If the current port is a Layer-2 aggregate port or if it works in full duplex mode, the link to which the 

current port connects is a point-to-point link. We recommend that you use the default setting, 

namely let MSTP detect the link status automatically.  

z 

This setting takes effect on the CIST and all MSTIs. If a port is configured as connecting to a 

point-to-point link or a non-point-to-point link, the setting takes effect for the port in all MSTIs. If the 

physical link to which the port connects is not a point-to-point link and you force it to be a 

point-to-point link by configuration, your configuration may incur a temporary loop.
