WLAN Function Interface
 It is the IP Address to communicate with AP.
 It is very important to make sure that the communication between
AP and WLAN interface is routable.

.
• IP address of the loopback interface has the first priority.
• If user does not setup Loopback interface, the lowest VLAN routing
interface will be selected, for example interface 4/1 has higher priority
than 4/2
than 4/2
.
• If the switch works as L2 devices, which means there is no VLAN routing
in this switch, the network management interface will be the WLAN
function interface.


A loopback interface is a permanent logical interface which must be
always up. As such, it provides a mean to configure a stable IP
address on the device that may be referred to by other switches. It
is typically used by routing protocols.
 Make sure what is the IP address of WLAN interface before
implementing APs.
