Usage Guidelines
The SSID profile configures the SSID.Default WMM mappings exist for all SSIDs. After you customize an WMM
mapping and apply it to the SSID, the controller overwrites the default mapping values and uses the user-
configured values.
Suite-B cryptography
The opmode parameters for Suite-B encryption, wpa2-aes-gcm-128 and wpa2-aes-gcm-256, require the ACR
license. Note, however, that not all controllers support Suite-B encryption. The table below describes the
controller support for Suite-B encryption in ArubaOS.
Controller Serial Number Prefix ACR License Support
W-7200 Series
All serial numbers supported Yes
W-600 Series All serial numbers supported Yes
W-3000 Series FC Yes
W-3000 Series F No
W-6000M3 card AK Yes

To determine the serial number prefix for your controller, issue the CLI command show inventory and note
the prefix before the system serial number. The serial number prefix in the example below appears in bold.
(host) #show inventory
Supervisor Card slot : 0
System Serial# : AK0093676
SC Assembly# : 2010052B (Rev:02.01)
SC Serial# : F01629529 (Date:03/29/10)

Multicast Rate Optimization
The Multicast Rate Optimization feature dynamically selects the rate for sending broadcast/multicast frames
on any BSS. This feature determines the optimal rate for sending broadcast and multicast frames based on the
lowest of the unicast rates across all associated clients.
When the Multicast Rate Optimization option (mcast-rate-opt) is enabled, the controller scans the list of all
associated stations in that BSS and finds the lowest transmission rate as indicated by the rate adaptation state
for each station. If there are no associated stations in the BSS, it selects the lowest configured rate as the
transmission rate for broadcast and multicast frames.
This feature is disabled by default. Multicast Rate Optimization applies to broadcast and multicast frames only.
802.11 management frames are not affected by this feature and will be transmitted at the lowest configured
rate.
The Multicast Rate Optimization feature should only be enabled on a BSS where all associated stations are sending
or receiving unicast data. If there is no unicast data to or from a particular station, then the rate adaptation state may
not accurately reflect the current sustainable transmission rate for that station. This could result in a higher packet
error rate for broadcast/multicast packets at that station.
