A phone cannot join, and the controller shows it on the exclusion list. An engineer is about to clear the entry and try again. What should they read first?
Select an answer to reveal the explanation.
Short Explanation
The phone is on the exclusion list for a reason, and clearing the entry without reading it just invites the same failure back. Read your reason first. A beacon timer does not explain the entry.
Full Explanation
An exclusion entry is the controller refusing a client for a while after a failure such as repeated authentication errors. Clearing it without reading the reason puts the phone back into the same failure. Read the reason first. A guest passphrase is not the reason code stored on the entry. The beacon interval does not clear exclusions and does not explain them. Antenna gain does not write the reason. The client is on the exclusion list. The exclusion entry shows why. Read that reason before clearing the entry and letting the client fail again. 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 reason might be a bad password, a certificate, or too many failures during a roam. The entry tells you which trail to follow. It does not fix the trail. Operational check: read the reason, fix that condition, then clear the entry and confirm the phone stays on.
