Operation Manual – MSTP
H3C S3100-52P Ethernet Switch
Chapter 1 MSTP Configuration
1-34
Note:
z
If you configure the link connected to a port in an aggregation group as a
point-to-point link, the configuration will be synchronized to the rest ports in the
same aggregation group.
z
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 MSTIs 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.
III. Configuration example
# Configure the link connected to Ethernet 1/0/1 as a point-to-point link.
1) Perform this configuration in system view
<Sysname> system-view
[Sysname] stp interface Ethernet 1/0/1 point-to-point force-true
2) Perform this configuration in Ethernet port view
<Sysname> system-view
[Sysname] interface Ethernet 1/0/1
[Sysname-Ethernet1/0/1] stp point-to-point force-true
1.3.14 Enabling MSTP
I. Configuration procedure
Follow these steps to enable MSTP in system view:
To do...
Use the
command...
Remarks
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 calculation, this operation
saves CPU resources of the switch.
