Configuring the Cisco Gigabit EtherSwitch EHWIC
OL-23155-01
DETAILED STEPS
To return to the default retransmission number, use the no dot1x max-req command in global
configuration mode.
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.
To disable multiple hosts on the port, use the no dot1x multiple-hosts command in interface
configuration mode.
SUMMARY STEPS
1. configure terminal
2. interface type 0/slot/port
3. dot1x multiple-hosts
4. end
5. show dot1x interface type 0/slot/port
Command Purpose
Step 1
configure terminal
Example:
Router#configure terminal
Enters global configuration mode.
Step 2
dot1x max-req count
Example:
Router(config)#dot1x max-req 3
Sets the number of times that the switch sends an EAP-request/identity
frame to the client before restarting the authentication process. The range
is 1 to 10; the default is 2.
Step 3
end
Example:
Router(config)#end
Returns to privileged EXEC mode.
Step 4
show dot1x
Example:
Router#show dot1x
Verifies your entries.
