Stp Port-Log - H3C S7500E Series Command Manual

Command Manual – MSTP
H3C S7500E Series Ethernet Switches
If the current port is the master port of a link aggregation group or if it works in full
duplex mode, the link to which the current port connects is a point-to-point link. We
recommend that you use the default setting, namely let MSTP detect the link
status automatically.
This setting is effective to the CIST and all spanning tree instances. If a port is
configured as connecting to a point-to-point link or a non-point-to-point link, the
setting takes effect for the port in all spanning tree instances. If the physical link to
which the port connects is not a point-to-point link and you force it to be a
point-to-point link by configuration, your configuration may incur a temporary loop.
Examples
# Configure port GigabitEthernet 2/0/1 as connecting to a point-to-point link.
<Sysname> system-view
[Sysname] interface GigabitEthernet 2/0/1
[Sysname-GigabitEthernet2/0/1] stp point-to-point force-true

1.1.28 stp port-log

Syntax
stp port-log { all | instance instance-id }
undo stp port-log { all | instance instance-id }
View
System view
Parameters
all: Enables output of port state transition information for all instances.
instance instance-id: Enables output of port state transition information for the
specified spanning tree instance. The effective range of instance-id is 0 to 31, with 0
representing the CIST.
Description
Use the stp port-log command to enable the output of port state transition information
for the specified instance or all instances.
Use the undo stp port-log command to disable the output of port state transition
information for the specified instance or all instances.
By default, the output of port state transition information is enabled.
Examples
# Enable output of port state transition information for instance 2.
