You are troubleshooting an AP joining issue. You have captured the CAPWAP join request sent from the AP to the controller. Which information do you export?

The AP's MAC address identifies the source of the join request, which is helpful, but less direct for diagnosing why a specific controller isn't being joined or found by name.

The controller's software version is typically determined after a successful join or during a subsequent exchange, not usually part of the initial CAPWAP join request from the AP.

The AP broadcast domain refers to the network segment; while relevant to connectivity, it's not a piece of information directly exported from the CAPWAP join request packet itself.

The name of the controller is often used by an AP for discovery, particularly through DNS resolution. If an AP fails to join, knowing the intended controller's name allows administrators to verify DNS records, controller reachability, and ensure the AP is targeting the correct wireless LAN controller during the CAPWAP discovery process.
