SSID Basic and Transmit Rates

In an effort to further optimize a dense deployment, I recently trimmed 6 Mbps from the basic/transmit rates on the 5GHz side.  To my surprise, I'm still seeing frames transmitted at 6 Mbps in a packet capture.  I verified from the beacon frames that 6 Mbps has been trimmed.  The only frames I see transmitted at 6 Mbps are QoS Null frames.  I do not see any other data frames operating at 6 Mbps.  On the Aruba side, things are working as they should since 6 Mbps isn't being advertised as an available rate.  So I can only assume that this is normal operation; I just can't find anything that states QoS Null frames will always be transmitted at 6 Mbps even if it's not a supported data rate.  Just wanted to have confirmation of this.

Re: SSID Basic and Transmit Rates

You also have to modify the 802.11a-Beacon-Rate parameter in the SSID profile under Advanced.

Re: SSID Basic and Transmit Rates

Beacon rate was modified to 12 Mbps.

Re: SSID Basic and Transmit Rates

I honestly don't know at what rate null data frames should be sent, or if it should adjust because the beacon rate has adjusted.
