Network including snooping
First Claim
1. As snooping apparatus comprising:
- a logic circuit with electronic memory tomonitor 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.

10. A network comprising:
-
an authentication server; at least one client; a network switch; and a snooping apparatus, said snooping apparatus comprising; a logic circuit with electronic memory for monitoring signal traffic with the at least one client and the network to determine, without changing the signal traffic, for each client, a network address and a port of said network switch to which that client is connected; providing to a first dynamic table the network address and port for each said client; accessing the 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 adding to the first dynamic table the user name, VLAN membership, VLAN tag and QoS information learnt from the authentication server in the second table. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
