3Com Switch 7750 Configuration Guide Guide

Leaf Node Configuration 241
Other MSTP-related settings can take effect only after MSTP is enabled on the
switch.
Configuration example
# Enable MSTP on the switch and disable MSTP on Ethernet1/0/1 port.
1 Configure in system view.
<SW7750> system-view
[SW7750] stp enable
[SW7750] stp interface ethernet1/0/1 disable
2 Configure in Ethernet port view.
<SW7750> system-view
[SW7750] stp enable
[SW7750] interface ethernet1/0/1
[SW7750-Ethernet1/0/1] stp disable
Leaf Node
Configuration
Table 172 lists MSTP-related configurations about leaf nodes.
Disable MSTP on the port stp 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.
