Manually Reauthenticating the Host

You can manually reauthenticate the host that is connected to a specific port at any time. When you want
to configure automatic 802.1x host reauthentication, see the
Reauthentication of the Host" section on page
To manually reauthenticate a host that is connected to a specific port, perform this task in privileged
mode:
Task
Manually reauthenticate the host that is connected
to a specific port.
This example shows how to manually reauthenticate the host that is connected to port 1 on module 4:
Console> (enable) set port dot1x 4/1 re-authenticate
Port 4/1 re-authenticating...
dot1x re-authentication successful...
dot1x port 4/1 authorized.

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
Enable multiple hosts on a specific port.
This example shows how to enable access for multiple hosts on port 1 on module 4:
Console> (enable) set port dot1x 4/1 multiple-host enable
Port 4/1 multiple hosts allowed.
