Use the display wlan wmm radio ap command to view the support of the radio chip for theEDCA parameters. Make sure the configured EDCA parameters are supported by the radiochip.2. Check that the values configured for the EDCA parameters are valid.3. Make sure the client is a non-WMM client, because SVP takes effect on only non-WMM clients.SVP or CAC configuration failureSymptomThe SVP packet priority mapping function configured with the wmm svp map-ac command does nottake effect.CAC configured with the wmm edca client command does not take effect.
