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?

Question

Accepted Answer

B. IP protocol 97 Cisco WLC mobility tunnels use EtherIP (IP Protocol 97) to encapsulate and forward client traffic between the foreign WLC and the anchor WLC. EPING specifically tests this data-path tunnel; if IP Protocol 97 is blocked by a firewall, the mobility tunnel cannot form and EPING will fail even if control-plane (UDP 16666) traffic is permitted.

Answer

A. UDP port 16666 UDP port 16666 carries mobility control messages between WLCs, not the EtherIP data-plane tunnel that EPING validates; allowing only port 16666 leaves the data tunnel blocked.

Answer

C. UDP port 97 UDP port 97 is not a valid Cisco WLC mobility protocol; IP Protocol 97 (EtherIP) is a Layer 3 protocol number, not a UDP destination port.

Answer

D. TCP port 97 TCP port 97 is not used by Cisco WLC mobility; EtherIP (IP Protocol 97) operates directly over IP without a TCP or UDP transport header.
