Command Usage
• The “max-count” parameter speci fied by this command is only
effective if the dot1x mode is set to “auto” by the dot1x port-control
command (page 4-111).
• 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.
Example
Console(config)#interface eth 1/2
Console(config-if)#dot1x operation-mode multi-host max-count 10
Console(config-if)#
