Controller-less WLANs

Unicast ARP-Only option on IAP
Requirement:

Does IAP supports conversion of ARP request packets to unicast ?



Solution:

Starting IAP version 4.3, a new option called "Unicast-ARP-Only" has been added in the SSID profile, under broadcast filtering.

Unicast-ARP-Only -> When set to Unicast-ARP-Only, the IAP allows all broadcast and multicast frames as it is, however the ARP requests are converted to unicast frames and sends them to the associated clients.



Configuration:

We can configure this option from the Web UI.

Edit the SSID Profile- Click on Show advanced option on WLAN Settings tab.

 

CLI :

 

 



Verification

We can verify this parameter from the IAP's CLI :

 

wlan ssid-profile CP-Test

 index 0
