3Com Switch 7750 Configuration Guide Guide

240 CHAPTER 29: MSTP CONFIGURATION
After you configure the link of a port as a point-to-point link, the configuration
applies to all spanning tree instances. If the actual physical link of a port is not a
point-to-point link and you forcibly configure the link as a point-to-point link,
temporary loops may be incurred.
Configuration example
# Configure the link connected to port Ethernet1/0/1 as a point-to-point link.
1 Configure in system view.
<SW7750> system-view
[SW7750] stp interface ethernet1/0/1 point-to-point force-true
2 Configure in Ethernet port view.
<SW7750> system-view
[SW7750] interface ethernet1/0/1
[SW7750-Ethernet1/0/1] stp point-to-point force-true
MSTP Configuration Configuration procedure
Tabl e 170 Enable MSTP in system view
Operation Command Description
Enter system view system-view -
Enable MSTP stp enable
Required
MSTP is disabled by default.
Disable MSTP on specified
ports
stp interface interface-list
disable
Optional
By default, MSTP is enabled
on all ports after you enable
MSTP in system view.
To enable a switch to operate
more flexibly, you can disable
MSTP on specific ports. As
MSTP-disabled ports do not
participate in spanning tree
generation, this operation
saves CPU resources.
Tabl e 171 Disable MSTP in Ethernet port view
Operation Command Description
