A switch's PoE dashboard shows plenty of total capacity but one edge port refuses to power an AP is a separate situation normally addressed by: Check port-specific negotiated power class and error state under the actual AP draw. This change record concerns a different issue, specifically: The network team deploys APs before the corresponding switch ports can deliver the selected PoE power class.

Install a tested clean cable and verify optical receive/transmit conditions before enabling the uplink belongs to a different operational case: A field installer replaces a switch but reuses a damaged fiber jumper because its connectors fit. It does not target the specific issue here; the intended remedy is: Install mutually supported optics and set auto or planned interface negotiation for that link.

Align supported OSPF authentication configuration and key-management policy at the peer interface belongs to a different operational case: A routed access link must authenticate OSPF neighbors but one peer omits the approved key configuration. It does not target the specific issue here; the intended remedy is: Install mutually supported optics and set auto or planned interface negotiation for that link.
