Enabling Mstp - H3C S5100-SI Series Operation Manual

Operation Manual – MSTP
H3C S5100-SI/EI Series Ethernet Switches
Note:
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.
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 GigabitEthernet 1/0/1 as a point-to-point link.
1) Perform this configuration in system view
<Sysname> system-view
[Sysname] stp interface GigabitEthernet 1/0/1 point-to-point force-true
2) Perform this configuration in Ethernet port view
<Sysname> system-view
[Sysname] interface GigabitEthernet 1/0/1
[Sysname-GigabitEthernet1/0/1] 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...
Enter system view
Enable MSTP
Disable MSTP on
specified ports
Use the
command...
system-view —
Required
stp enable
MSTP is disabled by default.
Optional
By default, MSTP is enabled on all ports
after you enable MSTP in system view.
stp interface
To enable a switch to operate more flexibly,
interface-list
you can disable MSTP on specific ports. As
disable
MSTP-disabled ports do not participate in
spanning tree calculation, this operation
saves CPU resources of the switch.
