Multi-Host Authentication
By default, 802.1x assumes that a single end user is connected to a single authenticator port in a one-to-one mode of authentication called
single-host mode. If multiple end users are connected to the same port, a many-to-one configuration, only the first end user to respond to
the identity request is authenticated. Subsequent responses are ignored, and a system log is generated to indicate reception of
unexpected 802.1x frames. When a port is authorized, the authenticated supplicant MAC address is associated with the port, and traffic
from any other source MACs is dropped.
Figure 9. Single-Host Authentication Mode
When multiple end users are connected to a single authenticator port, single-host mode authentication does not authenticate all end
users, and all but one are denied access to the network. For these cases, the Dell EMC Networking OS supports multi-host mode
authentication.
