Abstract
A new port state (called “Limited (Lim)”) and a new flag “Port-Limited”) are introduced. The Port-Limited flag is used to move a port of a network device from an Enabled state to the Limited state when the line protocol status for the port goes from down to up. In one embodiment, when the port is in the Limited port state, only a predefined set of protocols can work over the port. Restriction can be defined by the administrator of the network device.
