By default, the device checks wireless portal client validity according to ARP entries only. In wireless
networks where the AP forwards client traffic, the AC does not have ARP entries for clients.
Therefore, the AC cannot check the validity of portal clients by using ARP entries. To ensure that
valid users can perform portal authentication, you must enable wireless client validity check on the
AC.
This feature enables the AC to validate a client by looking up the client information in the WLAN
snooping table, DHCP snooping table, and ARP table. If the client information exists, the AC
determines the client to be valid for portal authentication.
To view information about WLAN or DHCP snooping entries, execute the display ip source binding
command.
