Modifying Interface Parameters
On interfaces in Layer 2 mode, you can set the port cost and port priority values.
•Port cost — a value that is based on the interface type. The previous table lists the default values. The
greater the port cost, the less likely the port is selected to be a forwarding port.
•Port priority — influences the likelihood that a port is selected to be a forwarding port in case that
several ports have the same port cost.
To change the port cost or priority of an interface, use the following commands.
• Change the port cost of an interface.
INTERFACE mode
spanning-tree rstp cost cost
The range is from 0 to 65535.
The default is listed in the previous table.
• Change the port priority of an interface.
INTERFACE mode
spanning-tree rstp priority priority-value
The range is from 0 to 240.
The default is 128.
