Interface parameters

Set the port cost and port priority values on interfaces in L2 mode.

Port cost Value based on the interface type. The previous table lists the default values. The greater the port cost, the less

likely the port is selected as a forwarding port.

Port priority Inuences the likelihood a port is selected to be a forwarding port in case several ports have the same port cost.

• Change the port cost of an interface in INTERFACE mode, from 1 to 200000000.

spanning-tree rstp cost cost

• Change the port priority of an interface in INTERFACE mode, from 0 to 240, default 128.
