In this mode, for the devices connected to this port, once a supplicant is authorized, the devices connected to this port can access the network resource through this port. 802. 1x Port-based Network Access Control function supported by the switch is little bit complex, for it just support basic "Enabled" mode, which can distinguish the device's MAC address and its VID. The following table is the summary of the combination of the authentication status and the port status versus the status of port mode, set in 802. 1x Port mode, port control state, set in 802. 1x port setting.

Auto: The controlled port is set to be in authorized state or unauthorized state depends on the result of the authentication exchange between the authentication server and the supplicant. Default: Force Authorized Port State: Show the port status of authorization.

[. . . ] A standard protocol for sending files between computer over a TCP/IP network and the internet. IGMP Snooping Internet Group Management Protocol. It is a Layer 3 protocol to report IP multicast memberships to neighboring multicast switches and routers. IGMP Snooping is a feature that allows an Ethernet Switch to "listen in" on the IGMP conversation between hosts and routers. When IGMP snooping is enabled in a switch, it prevent hosts on a local network from receiving traffic for a multicast group they have not explicitly joined. [. . . ]
