◆ The “max-count” parameter specified by this command is only effective
if the dot1x mode is set to “auto” by the dot1x port-control command.
◆ In “multi-host” mode, only one host connected to a port needs to pass
authentication for all other hosts to be granted network access.
Similarly, a port can become unauthorized for all hosts if one attached
host fails re-authentication or sends an EAPOL logoff message.
◆ In “mac-based-auth” mode, each host connected to a port needs to
pass authentication. The number of hosts allowed access to a port
operating in this mode is limited only by the available space in the
secure address table (i.e., up to 1024 addresses).
