One aspect of the instant application facilitates a source port-based identification of client role. During operation, the system can receive, at a network device, a network packet from a client device coupled to the network device via a port. The system can in response to determining that the port is a trusted port, apply a global trusted port configuration based on a first mapping table. The global trusted port configuration corresponds to a default client role. The system can in response to determining that a per-port configuration exists in a second mapping table and the client device is coupled to the trusted port, identify the per-port configuration that corresponds to a port-based client role to override the global trusted port configuration; and apply, based on the per-port configuration and a third mapping table, a policy to the subsequent network packets received via the port.
