Check for IP Configuration Problems

Incorrect IP Address on the Cisco Aironet 1200 AP for the Cisco Secure ACS￿Verify that the Cisco Aironet 1200 AP configuration has the correct IP address for the Cisco Secure ACS. Log in to the Cisco Aironet 1200 AP, and choose Setup > Security > Authentication Server to verify the IP address configuration.

IP Connectivity Problem￿Verify that the Cisco Secure ACS can ping the Cisco Aironet 1200 AP. If it can not, then you will need to resolve any IP connectivity issues before LEAP will work. Look for default gateway issues on the Cisco Aironet 1200 AP. Log in to the 1200 AP, and choose Setup > Express Setup to verify the current IP configuration. On the Cisco Secure ACS, issue the ipconfig /all command from a command prompt.

Native VLAN Problem￿The Cisco Aironet 1200 AP sends all authentication traffic on the native VLAN. Verify that the 1200 AP is using the correct native VLAN to send traffic to the Cisco Secure ACS. Log in to the Cisco Aironet 1200 AP, and choose Setup > VLAN. Issue the show interface fastethernet 2/3 switchport to verify that the 1200 AP port is configured for the correct native VLAN.
