Why Cannot an AP Go Online When the AR Functions as an AC?

Why Cannot an AP Go Online When the AR Functions as an AC?

  • The AP is not in the list of APs that are supported by the AR.
  • The AC function is used with a license and is unavailable by default.
  • No PVID is configured for the network access device directly connected to the AP.
  • SN or MAC address authentication is enabled on the AC, but the AP is not on the AP whitelist.
  • When the capwap dtls control-link encrypt command is not configured on the AC, enabling control tunnel encryption using DTLS will cause a DTLS negotiation failure. As a result, the CAPWAP tunnel fails to be established.
  • The CAPWAP heartbeat detection interval and number of CAPWAP heartbeat detections on the AC are proper. If the CAPWAP heartbeat detection interval and number of CAPWAP heartbeat detections are smaller than the default values, the CAPWAP link reliability is degraded and the AP cannot properly go online. Typically, default values are recommended. If default values are used, the AP will go offline unexpectedly. In this case, you can run the capwap echo command to set a larger CAPWAP heartbeat detection interval and number of CAPWAP heartbeat detections.
