A client never gets an address. A capture on the access-point switch port shows the client's DHCP discover and no offer. Where is the evidence the server did not answer?
Select an answer to reveal the explanation.
Short Explanation
The discover left and nothing came back. That capture is your evidence the server did not answer. A beacon does not carry a DHCP offer.
Full Explanation
A capture on the access-point switch port sees the client's DHCP after local mode has delivered it toward the controller's VLAN, or the branch VLAN if the client is switched there. This capture shows a discover and no offer, which is the evidence the server did not answer. A beacon does not carry DHCP. Antenna gain does not record offers. A guest passphrase does not store a discover. A capture on the access-point switch port shows the client's DHCP discover and no offer. That capture is the evidence the server never answered. Check one live client after the change and leave the rest of the floor alone until that client matches the result you expected. Confirm the symptom on the next attempt before changing anything else. Exam caveat: the capture has to be on the VLAN the client is actually using. A capture on the access-point management VLAN can miss a client DHCP that lives on another VLAN. Operational check: confirm the capture is on the client VLAN, then fix the server or the helper until an offer appears.
