Item Description
STP Selects whether to enable STP on the port.
Protection
Sets the type of protection to be enabled on the port:
•
Not Set
—No protection is enabled on the port.
•
Edged Port, Root Protection, Loop Protection
—For more information,
see Table 67 .
Instance
(Instance ID,
Port Priority,
Auto Path
Cost, and
Manual Path
Cost)
Sets the priority and path cost of the port in the current MSTI:
•
Priority
—The priority of a port is an important factor in determining whether the
port can be elected as the root port of a device. If all other conditions are the
same, the port with the highest priority will be elected as the root port. On an
MSTP-enabled device, a port can have different priorities in different MSTIs, and
the same port can play different roles in different MSTIs, so that data of different
VLANs can be propagated along different physical paths, implementing
per-VLAN load balancing. You can set port priority values based on the actual
networking requirements.
•
Path cost
—A parameter related to the rate of a port. On an MSTP-enabled
device, a port can have different path costs in different MSTIs. Setting
appropriate path costs allows VLAN traffic flows to be forwarded along different
physical links, achieving VLAN-based load balancing. The device can
automatically calculate the default path cost. Alternatively, you can also
manually configure path cost for ports.
