Configuration guidelines
Follow these guidelines when you configure inter-AC roaming:
• The SSIDs and the authentication and encryption modes of two APs should be the same.
• An IACTP tunnel must be configured on both of the two ACs.
Configuring AC 1 and AC 2
If remote authentication is required in the authentication mode you select, configure the RADIUS server.
For information about how to configure the RADIUS server, see " Configuring RADIUS ."
1. Establish AC-AP connections:
Configure AC 1 and AC 2 to establish a connection between AP 1 and AC 1, and between AP 2
and AC 2. You see that the two APs are in the running status only after you establish the
connections. To view the AP status, select Summary > AP or AP > AP Setup.
For the related configuration, see "
Configuring access services ."
NOTE:
For the configuration of authentication mode, see " Configuring access services ." Fast roaming
supporting key caching can be implemented only when RSN+802.1X authentication is adopted.
2. Configure an IACTP tunnel:
a. Select Roam > Roam Group from the navigation tree.
b. On the page that appears, select Enable from the IACTP Tunnel list, select IPv4 from the IP Type
list, enter 192.168.1.100 for Source address, the IP address of AC 1, enter the IP address of
AC 2 in the member list, and click Add.
c. Click Apply.
