What to look for when clients behind a wireless bridge or VMware devices does not receive an IP address ?

Aruba Employee

This article applies to Aruba Mobility Controllers running ArubaOS version 6.3.0.0 and below.

 

If your controller supports clients behind a wireless bridge or virtual clients on VMware devices, you must disable the below settings to allow those clients to obtain an IP address.

In 
ArubaOS releases Prior to 6.1.3.2, the virtual AP profile included two unique broadcast filter parameters :

Drop broadcast and multicast parameter, which filtered out all broadcast and multicast traffic in the air except DHCP response frames (these were converted to unicast frames and sent to the corresponding client)

Convert ARP requests to unicast parameter, which converted broadcast ARP requests to unicast messages sent directly to the client.

Starting with ArubaOS 6.1.3.2, the Convert Broadcast ARP requests to unicast setting includes the additional functionality of broadcast-filter all parameter, where DHCP response frames are sent as unicast to the corresponding client. This can impact DHCP discover/requested packets for clients behind a wireless bridge and virtual clients on VMware devices. Disable this option to resolve this issue and allow clients behind a wireless bridge or VMware devices to receive an IP address.

Default: Enabled
