To return to the default retransmission number, use the no dot1x max-req global configuration
command.
Enabling Multiple Hosts
You can attach multiple hosts to a single 802.1x-enabled port. In this mode, only one of the attached
hosts must be successfully authorized for all hosts to be granted network access. If the port becomes
unauthorized (reauthentication fails, and an EAPOL-logoff message is received), all attached clients are
denied access to the network.
Beginning in privileged EXEC mode, follow these steps to allow multiple hosts (clients) on an
802.1x-authorized port that has the dot1x port-control interface configuration command set to auto.
SUMMARY STEPS
1. configure terminal
2. interface interface-id
3. dot1x multiple-hosts
4. end
5. show dot1x interface interface-id
6. copy running-config startup-config
DETAILED STEPS

Step 4
show dot1x
Verifies your entries.
Step 5
