Enabling Mstp - 3Com WX3000 Series Operation Manual

To do...
Specify whether the link
connected to a port is a
point-to-point link
Among aggregated ports, you can only configure the links of master ports as point-to-point links.
If an auto-negotiating port operates in full duplex mode after negotiation, you can configure the link
of the port as a point-to-point link.
After you configure the link of a port as a point-to-point link, the configuration applies to all the spanning
tree instances the port belongs to. 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, loops may occur temporarily.
Configuration example
# Configure the link connected to GigabitEthernet 1/0/1 as a point-to-point link.
1) Perform this configuration in system view
<device> system-view
[device] stp interface GigabitEthernet1/0/1 point-to-point force-true
2) Perform this configuration in Ethernet port view
<device> system-view
[device] interface GigabitEthernet1/0/1
[device-GigabitEthernet1/0/1] stp point-to-point force-true

Enabling MSTP

Configuration procedure
Follow these steps to enable MSTP in system view:
To do...
Enter system view
Enable MSTP
Disable MSTP on
specified ports
Follow these steps to enable MSTP in Ethernet port view:
Use the command...
stp point-to-point { force-true
| force-false | auto }
Use the command...
system-view
stp enable
stp interface interface-list
disable
1-28
Required
The auto keyword is adopted
by default.
Remarks
—
Required
MSTP is disabled by default.
Optional
By default, MSTP is enabled on all ports after
you enable MSTP in system view.
To enable a device to operate more flexibly, you
can disable MSTP on specific ports. As
MSTP-disabled ports do not participate in
spanning tree calculation, this operation saves
CPU resources of the device.
