Table2-15 Configure the Path Cost of a port
Operation Command
Configure the Path Cost of a port stp [ instance instance-id ] cost cost
Restore the default path cost of a port. undo stp [ instance instance-id ] cost
You can configure the path cost of a port with either of the above-mentioned measures.
For more about the commands, refer to the Command Manual.
Upon the change of path cost of a port, MSTP will recalculate the port role and transit
the state. When instance-id takes 0, it indicates to set the path cost on the CIST.
By default, MSTP is responsible for calculating the port path cost.
2.2.11 Configure the Priority of a Port
For spanning tree calculation, the port priority is an importance factor to determine if a
port can be elected as the root port. With other things being equal, the port with the
highest priority will be elected as the root port. On the MSTP switch, a port can have
different priorities in different STIs and plays different roles respectively. Thus the traffic
from different VLANs can run over different physical links, thereby implementing the
VLAN-based load-balancing.
You can configure the port priority in the following ways.
I. Configure in system view
Perform the following configuration in system view.
