Abstract
An apparatus includes: a logic circuit with electronic memory to: monitor signal traffic with at least one client and a computer network to determine, without changing the signal traffic, for each client, a network address and a port to which that client is connected; provide to a first dynamic table the network address and port for each said client; access an authentication server that has a second table of user names and corresponding passwords for network login, in which the second table also includes for each user name and password a corresponding virtual local network (VLAN) membership and/or VLAN tag and/or Quality of Service (QoS); and add to the first dynamic table the user name, VLAN membership, VLAN tag and QoS information learnt from the authentication server in the second table.
