Security cannot be enabled on a port in single-host mode.)
• Multiple Host — Multiple hosts can be attached to a single
802.1x-enabled port. Only the first host must be authorized, and
then the port is wide-open for all who want to access the network.
If the host authentication fails, or an EAPOL-logoff message is
received, all attached clients are denied access to the network.
• Multiple Session — A number of specific authorized hosts may
access the port. Each host is treated as if it was the first and only
user and must be authenticated. Filtering is based on the source
MAC address.
– Action on Single Host Violation — Select the action to be applied to
packets arriving in Single Session/Single Host mode, from a host
whose MAC address is not the supplicant MAC address. The options
are:
• Discard — Discard the packets from any unlearned source.
• Forward — Forward the packets from an unknown source,
however, the MAC address is not learned.
