1.3.4 Timeout Time Factor Configuration

Refer to section 1.2.9 "Timeout Time Factor Configuration".

1.3.5 Maximum Transmitting Speed Configuration

Refer to section 1.2.10 "Maximum Transmitting Speed Configuration".

1.3.6 Edge Port Configuration

Refer to section 1.2.11 "Edge Port Configuration".

1.3.7 Path Cost Configuration

The path cost parameters reflects the link rates on ports. For a port on an
MSTP-enabled switch, the path cost may differ with spanning tree instance. You can
enable flows of different VLANs to travel along different physical links by configuring
appropriate path costs on ports, so that load balancing can be achieved by VLANs.
The switch can automatically calculate the path costs of ports, but you can also
manually configure them.
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:
dot1d-1998: Adopts the IEEE 802.1D-1998 standard to calculate the default path
costs of ports.
dot1t: Adopts the IEEE 802.1t standard to calculate the default path costs of ports.
legacy: Adopts the standard defined by Huawei-3Com to calculate the default
path costs of ports.
