A method is provided for a port management system in which a switch is automatically provisioned with network resources. A command or set of commands are stored and automatically executed on the switch upon the occurrence of a defined network event. The command or set of commands may be associated with one or more ports on the switch. When executed, the commands cause a change to a port configuration and/or policy on the switch to control access to a network resource. The network resource may include any device or service accessible on the network. The defined network event may include any network event associated with a device or user connected to the network. The command or set of commands may reference variables, control structures, and functions to modify command execution.
