”.
1.3.6 Configuring a Port as an Edge
Refer to section 1.2.12 “Configuring the Current Port as an Edge Port”.
1.3.7 Configuring the Path Cost for a Port
The path cost parameter reflects the rate of the link connected to the port. For a port on
an MSTP-enabled switch, the path cost may be different in different spanning tree
instances. You can enable flows of different VLANs to travel along different physical
links by configuring appropriate path costs on ports, so that VLAN-based load
balancing can be implemented.
Path cost of a port can be determined by the switch or through manual configuration.
I. Standards for calculating path costs of ports
Currently, a switch can calculate the path costs of ports based on one of the following
standards:
z dot1d-1998: Adopts the IEEE 802.1D-1998 standard to calculate the default path
costs of ports.
z dot1t: Adopts the IEEE 802.1t standard to calculate the default path costs of ports.
z legacy: Adopts the proprietary standard to calculate the default path costs of
ports.
