This command allows single or multiple hosts (clients) to connect to an

single host. Use the no form with the multi-host max-count keywords to restore the
default maximum count.

Command Usage
• 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 (page 4-105).
• 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).
Example
Console(config)#interface eth 1/2
