Enabling Multiple Hosts

You can enable a specific port to allow multiple users. When a port is enabled for multiple users, and a host that is connected to that port is authorized successfully, any host (with any MAC address) is allowed to send and receive traffic on that port. If you connect multiple hosts to that port through a hub, you can reduce the security level on that port.

To enable access for multiple users on a specific port, perform this task in privileged mode:

Task

Command

Enable multiple hosts on a specific port. create port dot1x mod/port multiple-host enable

Disabling Multiple Hosts

You must disable access for multiple users on any port where it is enabled.

To disable access for multiple users on a specific port, perform this task in privileged mode:

Task

Command

Disable multiple hosts on a specific port. create port dot1x mod/port multiple-host disable
