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.
