Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 34

Guest anchoring is configured for a newly created SSID for a company. It has been noticed that the mobility tunnels are not up and that MPING fails from your foreign WLC to the anchor WLC. What is the reason that it is failing?

Answer options

• A. A rule is needed at the firewall to allow UDP port 16666 for communication to work.
• B. A rule is needed at the firewall to allow UDP port 97 for communication to work.
• C. A rule is needed at the firewall to allow TCP port 97 for communication to work.
• D. A rule is needed at the firewall to allow TCP port 16666 for communication to work.

Correct answer: A

Explanation

The correct answer is A because UDP port 16666 is specifically used for the mobility tunnel communication between the foreign and anchor WLCs. The other options suggest using different ports or TCP, which are not applicable for this specific communication requirement.
