authentication method as open-system, and then enable the WLAN service template.

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.
