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 are transmitted at the lowest configured rate.
Example
The following command configures an SSID for WPA2 AES authentication:
(host) (config) #wlan ssid-profile corpnet
essid Corpnet
opmode wpa2-aes
Command History
Command Information
Note: 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.
Release Modification
ArubaOS 3.0 Command introduced
ArubaOS 3.2 The wmm-ts-min-inact-int parameter was introduced. The wpa2-preauth parameter was
removed,
ArubaOS 3.3 Support for the high-throughput IEEE 802.11n standard was introduced including the ht-
ssid-profile parameter and various rate changes.
ArubaOS 3.3.1 Support for configurable WMM AC mapping was introduced including the wmm-be-dscp,
wmm-bk-dscp, wmm-vi-dscp, and wmm-vo-dscp parameters.
ArubaOS 3.4 The deny-bcast and disable-probe-retry parameters were introduced. The drop-mcast
parameter was deprecated.
ArubaOS 3.4.1 License requirements changed in ArubaOS 3.4.1, so the command required the PEF license
instead of the Voice Services Module license required in earlier versions.
ArubaOS 6.1 The opmode options wpa2-aes-gcm-128 and wpa2-aes-gcm-256 were introduced. These
parameters require the ACR license.
The qbss-load-enable option is included.
