178 CHAPTER 13: MSTP CONFIGURATION
Configuration procedure in system view
Configuration procedure in Ethernet port view
Only the master ports of aggregation ports can be configured to connect to
point-to-point link.
You can configure a port to connect to point-to-point link if the port operates in
auto-negotiation mode and the negotiated operation mode is full duplex.
If you configure a port to connect to a point-to-point link, the port will connect to
point-to-point links in all spanning tree instances. If the actual physical link is not a
point-to-point link, loops may temporarily appear.
Table155 Configure a port to connect to a point-to-point link in system view
Operation Command Description
Enter system view system-view -
Specify whether the specified
ports connect to
point-to-point links or not
stp interface interface-list
point-to-point { force-true |
force-false | auto }
Required
The auto keyword is specified by
default.
The force-true keyword specifies
that the specified ports connect to
point-to-point links.
The force-false keyword specifies
that the specified ports connect to
links that are not point-to-point.
The auto keyword specifies that
MSTP automatically determines
whether the specified Ethernet
ports connect to point-to-point
links.
Table156 Configure a port to connect to a point-to-point link in Ethernet port view
Operation Command Description
Enter system view system-view -
Enter Ethernet port view interface interface-type
interface-number
-
Configure the port to connect
to a point-to-point link
stp point-to-point {
force-true | force-false |
auto }
Required
The auto keyword is specified by
default.
The force-true keyword specifies
that the port connect to a
point-to-point link.
The force-false keyword
specifies that the port connect to
a link that is not point-to-point.
The auto keyword specifies that
MSTP automatically determines
whether the Ethernet port
connects to a point-to-point link.
