802.1T standard does. The following formula is used to calculate the path cost of an
aggregated link:
Path cost = 200,000,000 / link transmission speed,
Where the link transmission speed is the sum of the speeds of the unblocked ports on
the aggregated link, which is measured in 100 Kbps.
Examples
# Configure to use the IEEE 802.1D-1998 standard to calculate the default path costs
of ports.

1.1.32 stp point-to-point
Syntax
stp point-to-point { force-true | force-false | auto }
undo stp point-to-point
View
Ethernet port view
Parameters
force-true: Specifies that the link connected to the current Ethernet port is a
point-to-point link.
force-false: Specifies that the link connected to the current Ethernet port is not a
point-to-point link.
auto: Specifies to automatically determine whether or not the link connected to the
current Ethernet port is a point-to-point link.
Description
Use the stp point-to-point command to specify whether the link connected to the
current Ethernet port is a point-to-point link.
Use the undo stp point-to-point command to restore the link connected to the current
Ethernet port to its default link type, which is automatically determined by MSTP.
