If a client wants to use a high-priority AC (AC-VO or AC-VI), it must send a request to the AP. If the
number of clients using high-priority ACs (AC-VO and AC-VI) plus the clients requesting for high-priority
ACs (AC-VO and AC-VI) on AP 1 or AP 2 is smaller than or equal to the maximum number of
high-priority AC clients (10 in this example), the request is accepted; otherwise, the request is denied.
Troubleshooting
EDCA Parameter Configuration Failure
Symptom
Configuring EDCA parameters for an AP failed.
Analysis
The EDCA parameter configuration of an AP is restricted by the radio chip of the AP.
Solution
1) Use
the
display wlan wmm radio ap ap-name command to view the support of the radio chip for
the EDCA parameters. Make sure the configured EDCA parameters are supported by the radio
chip.
2) Check that the values configured for the EDCA parameters are valid.
SVP or CAC Configuration Failure
Symptom
The SVP packet priority mapping function configured with the wmm svp map-ac command does not
take effect.
CAC configured with the wmm edca client command does not take effect.
Analysis
The SVP packet priority mapping function or CAC takes effect only after WMM is enabled.
