Release Notes

Parameter Description Range Default
vlan
The VLAN(s) into which users
are placed in order to obtain
an IP address. Enter VLANs
as a comma-separated list of
existing VLAN IDs or VLAN
names. A mixture of names
and numeric IDs are not
allowed.
1
vlan-mobility
VLAN mobility retains the
client VLAN on roaming
irrespective of the VAP VLAN,
provided the user VLANs are
extended.
VLAN mobility and mobile IP
are mutually exclusive.
VLAN mobility does not re-
use user firewall sessions on
roaming as the sessions will
have to be recreated locally
on the roamed controller.
— disabled
wmm-traffic-management-profile
Specify the WMM Traffic
Management Profile to be
associated with this Virtual
AP Profile.

Usage Guidelines
Wireless LAN profiles configure WLANs in the form of virtual AP profiles. A virtual AP profile contains an SSID
profile which defines the WLAN and an AAA profile which defines the authentication for the WLAN. You can
configure and apply multiple instances of virtual AP profiles to an AP group or to an individual AP.
A named VLAN can be deleted although it is configured in a virtual AP profile. If this occurs the virtual AP
profiles becomes invalid. If the named VLAN is added back later the virtual AP becomes valid again.
Beginning with ArubaOS 6.1.3.2, the broadcast-filter arp parameter is enabled by default. Behaviors
associated with these settings are enabled upon upgrade to ArubaOS 6.1.3.2. If your controller supports
clients behind a wireless bridge or virtual clients on VMware devices, you must disable the broadcast-filter arp
setting to allow those clients to obtain an IP address. In previous releases of ArubaOS, the virtual AP profile
included two unique broadcast filter parameters; the broadcast-filter all 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) and the broadcast-filter arp parameter, which converted
broadcast ARP requests to unicast messages sent directly to the client.
Starting with ArubaOS 6.1.3.2, the broadcast-filter arp 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 the broadcast-filter arp setting using the wlan virtual-ap <profile> no broadcast-
filter arp command to resolve this issue and allow clients behind a wireless bridge or VMware devices to
receive an IP address.
In ArubaOS 6.2 and later, if there is only one VLAN defined, then the controller will send IPv6 router
advertisements (RAs) as usual. If, however, there are multiple VLANs, then the controller will automatically
convert 802.11 multicast frames to unicast. This conversion prevents RA frames from being sent with a
multicast key to all clients on the BSSID, which could lead to clients having multiple IPv6 addresses.
