Stp Port Priority - 3Com 8807 Command Reference Manual

MSTP Configuration Commands 199
auto: Configures to automatically check if the link to the Ethernet port is a
point-to-point link.
Description
Use the stp point-to-point command to configure the current Ethernet port (not)
to connect with point-to-point link.
Use undo stp point-to-point command to configure the link state to the default
state in which MSTP automatically detects if the link to the Ethernet port is
point-to-point link.
By default, switch adopts auto mode.
The port not connected with the point-to-point link cannot transit fast.
The master ports of the link aggregation and the ports operating in full-duplex
mode are connected to the point-to-point link. You are recommended to keep the
default settings and let MSTP detect the link state automatically.
This configuration takes effect on the CIST and all the MSTIs. The settings of a port
whether to connect the point-to-point link will be applied to all the MSTIs where
the port belongs. Note that a temporary loop may be redistributed if you configure
a port not physically connected with the point-to-point link as connected to such a
link by force.
Related command: stp interface point-to-point.

# Configure Ethernet2/1/3 to be connected to the point-to-point link.
