Question
An engineer working for an enterprise deployed multiple Cisco WLCs. A controller that sits in the R&D division is connected through a firewall and is part of the same mobility group. The engineer must ensure that the mobility tunneling is available through the firewall and test it as R&D engineers roam the production floor within their department. How is this requirement met?
Options
- Amping on UDP port 16666 and eping on Protocol 96 between management ports
- Bmping on UDP port 16666 and eping on Protocol 97 between management ports
- Cmping on UDP port 16667 and eping on Protocol 97 between management ports
- Dmping on UDP port 16667 and eping on Protocol 96 between management ports

Explanation
For mobility tunneling through a firewall in a Cisco wireless network environment, UDP port 16666 must be open along with IP Protocol number `97', which is used for Encapsulating Security Payload (ESP) traffic typically found in IPsec tunnels. By ensuring these ports are mapped correctly through the firewall, R&D engineers can roam within their department while maintaining a secure mobility tunnel.
