What is max-tx-fail config from SSID-profle and how it is useful?
Environment Typically in VOIP deployments.
Maximum Transmit Failures configuration
If this is set to “x”, after “x” number of consecutive transmissions failures to the client, client is de-authenticated (say max-tx-fail is set to 25 & max-retries set to 8, this would mean 200 transmission failures for the knob to kick-in). This helps in preserving air time from sending packets to far away sticky clients which continues to keep failing, also this may help in making far away sticky client to better AP (after de-authenticated, it may associate to some other close by AP instead of trying the same AP again).
Especially VOIP traffic is sensitive and we always prioritize air traffic so it would be better to set a value increased to 25.
