An engineer has configured guest anchoring for a newly created SSD however, the mobility tunnels are not up, and EPING is failing from the foreign WLC to the anchor WLC. Which traffic flow must be allowed at the firewall to enable the communication?
A. UDP port 16666
B. IP protocol 97
C. UDP port 97
D. TCP port 97
Wrong, its B.
Yes, B is the correct. A would be correct if mping was failing.
