Stp Port Priority - 3Com 7750 Series Command Reference Manual

3Com Switch 7750 Series
Command Reference Guide – MSTP
Description
Use the stp point-to-point command to specify whether the link connected to the
current Ethernet port is a point-to-point link.
Use the undo stp point-to-point command to restore the link connected to the current
Ethernet port to its default link type, which is automatically determined by MSTP.
If no keyword is specified in the stp point-to-point command, the auto keyword is
used by default, and so MSTP automatically determines the type of the link connected
to the current port.
The rapid transition feature is not applicable to ports on non-point-to-point links.
If an Ethernet port is the master port of an aggregation port or operates in full-duplex
mode, the link connected to the port is a point-to-point link.
You are recommended to let MSTP automatically determine the link types of ports.
These two commands only apply to CISTs and MSTIs. If you configure the link to which
a port is connected is a point-to-point link (or a non-point-to-point link), the configuration
applies to all spanning tree instances (that is, the port is configured to connect to a
point-to-point link [or a non-point-to-point link] in all spanning tree instances). If the
actual physical link is not a point-to-point link and you configure the link to which the
port is connected to be a point-to-point link, loops may temporarily occur.
Related command: stp interface point-to-point.
Example
# Configure the link connected to Ethernet1/0/3 port as a point-to-point link.
