--> 802.1x host mode indicates how many devices can be authenticated on a single network port.
--> 802.1x supports five host modes
i) Single Host Mode:
--> Only one device is allowed to get access to the network.
--> If the device is changed or replaced it is not allowed to get the access after authentication.
ii) Multiple Host Mode:
--> Multiple Devices are allowed to get access to the network.
--> Used when hub or wireless devices are connected to the port.
iii) Multiple Domain Authentication Mode:
--> This mode allows single IP Phone and single host to get access to the network.
--> Switch places the host in data vlan and IP Phone in voice vlan
iv) Multiple Authentication Mode:
--> This mode allows a single IP phone and multiple hosts to get access to the network.
--> This mode provides advantage over Multiple Host mode, by allowing every user to get authenticated separately when connected via single port.
--> Used when hub or wireless access point is connected to the port.
