Configuring 802.1X Port-Based Authentication
This example shows how to configure a switch to derive the reauthentication period from the server and to verify the
configuration:
Cisco IOS Release 12.2(50):
Switch# configure terminal
Switch(config)# interface f7/1
Switch(config-if)# switchport mode access
Switch(config-if)# dot1x pae authenticator
Switch(config-if)# authentication timer reauthenticate server
Switch(config-if)# end
Switch# show dot1x interface f7/1 det
Dot1x Info for FastEthernet7/11
-----------------------------------
PAE = AUTHENTICATOR
PortControl = FORCE_AUTHORIZED
ControlDirection = Both
HostMode = SINGLE_HOST
ReAuthentication = Disabled
QuietPeriod = 60
ServerTimeout = 30
SuppTimeout = 30
ReAuthPeriod = (From Authentication Server)
ReAuthMax = 2
MaxReq = 2
TxPeriod = 30
RateLimitPeriod = 0
Dot1x Authenticator Client List Empty
Port Status = AUTHORIZED
Switch#
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# interface
interface-id
Enters interface configuration mode.
Step 3
Switch(config-if)# switchport mode
access
Specifies a nontrunking, nontagged single VLAN Layer 2 interface.
Step 4
Switch(config-if)# dot1x pae
authenticator
Enables 802.1X authentication on the port with default parameters.
Refer to the “Default 802.1X Configuration” section on page 49-27.
Step 5
Cisco IOS Release 12.2(50)SG and later
Switch(config-if)# authentication
timer reauthenticate {interface
|
server}
Cisco IOS Release 12.2(46)SG or earlier
releases
Switch(config-if)# dot1x timeout
reauth-attempts {interface
| server}
Sets the reauthentication period (seconds).
Step 6
Switch(config-if)# end
Returns to privileged EXEC mode.
Step 7
Switch# show dot1x interface
interface-id details
Verifies your entries.
Step 8
Switch# copy running-config
startup-config
(Optional) Saves your entries in the configuration file.
