H3C S3100 Series Ethernet Switches Chapter 1 MSTP Configuration
1-37
1.4.1 Configuration Prerequisites
The role (root, branch, or leaf) of each switch in each spanning tree instance is
determined.
1.4.2 Configuring the MST Region
Refer to section 1.3.2 “Configuring an MST Region”.
1.4.3 Configuring the Mode a Port Recognizes and Sends MSTP Packets
Refer to section 1.3.5 “Configuring the Mode a Port Recognizes and Sends MSTP
Packets
”.
1.4.4 Configuring the Timeout Time Factor
Refer to section 1.3.10 “Configuring the Timeout Time Factor”.
1.4.5 Configuring the Maximum Transmitting Speed on the Current Port
Refer to section 1.3.11 “Configuring the Maximum Transmitting Speed on the Current
Port
”.
1.4.6 Configuring a Port as an Edge Port
Refer to section 1.3.12 “Configuring the Current Port as an Edge Port”.
1.4.7 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.
