z Configured in Layer 2 aggregate port view, the setting takes effect only on the aggregate port.
Configured on a member port in an aggregation group, the setting can take effect only after the port
leaves the aggregation group.
z Setting different priorities for the same port in different MSTIs allows VLAN traffic flows to be
forwarded along different physical links, thus to achieve VLAN-based load balancing.
z When the priority of a port is changed in an MSTI, MSTP will re-compute the role of the port and
initiate a state transition in the MSTI.

Examples
# Set the priority of port GigabitEthernet 1/0/3 in MSTI 2 to 16.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/3
[Sysname-GigabitEthernet1/0/3] stp instance 2 port priority 16
stp port-log
Syntax
stp port-log { all | instance instance-id }
undo stp port-log { all | instance instance-id }
View

Default Level
2: System level
Parameters
all: Enables output of port state transition information for all MSTIs.
instance instance-id: Enables output of port state transition information for the specified MSTI. The
minimum value of instance-id is 0, representing the CIST, and the maximum value of this argument is 3.
Description
Use the stp port-log command to enable output of port state transition information for the specified
MSTI or all MSTIs.
Use the undo stp port-log command to disable output of port state transition information for the
specified MSTI or all MSTIs.
This function is enabled by default.
Examples
# Enable output of port state transition information for MSTI 2.
