Chapter 49 Configuring 802.1X Port-Based Authentication
Configuring 802.1X Port-Based Authentication
The following example illustrates how to configure a switch for downloadable policy:
Switch# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# aaa new-model
Switch(config)# aaa authorization network default local
Switch(config)# ip device tracking
Switch(config)# ip access-list extended default_acl
Switch(config-ext-nacl)# permit ip any any
Switch(config-ext-nacl)# exit
Switch(config)# radius-server vsa send authentication
Switch(config)# int fastEthernet 2/13
Switch(config-if)# ip access-group default_acl in
Switch(config-if)# exit
Configuring 802.1X Authentication with Per-User ACL and Filter-ID ACL
This section includes the following topics:
• Per-User ACL and Filter-ID ACL, page 49-46
• Configuring a Per-User ACL and Filter-ID ACL, page 49-52
Step 8
Switch(config)# ip device tracking
Enables the IP device tracking table.
To disable the IP device tracking table, use the no ip device tracking
global configuration commands.
Step 9
Switch(config)# ip device tracking
[probe {count count | interval
interval}]
(Optional) Configures these parameters for the IP device tracking table:
• count—Number of times that the switch sends the ARP probe. The
range is 1 to 5. The default is 3.
• interval—Number of seconds that the switch waits for a response
before resending the ARP probe. The range is 30 to 300 seconds. The
default is 30 seconds.
Step 10
Switch(config)# ip device tracking
[probe {delay interval}]
(Optional) Configures the optional probe delay parameter for the IP
device tracking table:
• interval—Number of seconds that the switch delays sending an ARP
probe, triggered by link-up and ARP probe generation by the tracked
device. The range is 1 to 120 seconds. The default is 0 seconds.
Step 11
Switch(config)# radius-server vsa
send authentication
Configures the network access server to recognize and use vendor-specific
attributes.
Note The downloadable ACL must be operational.
Step 12
Switch(config)# end
Returns to privileged EXEC mode.
Step 13
Switch# show ip device tracking
{all | interface interface-id | ip
ip-address | mac mac-address}
Displays information about the entries in the IP device tracking table.
Step 14
Switch# copy running-config
startup-config
(Optional) Saves your entries in the configuration file.
