Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 83

An enterprise network administrator is asked to set up an experimental WLAN for a collaboration project with a local service provider. The WLAN must be anchored to a WLC in the service provider data center using legacy mobility mode. After the configurations are completed on the WLCs and the firewalls in the path, the data path mobility tunnel is failing to come up. What should be performed by the administrator to debug the issue?

Answer options

• A. Establish a Telnet connection from a local PC to the firewall on port 97.
• B. Use the eping command on the WLC.
• C. Establish a Telnet connection from a local PC to the firewall on port 16666.
• D. Use the mping command on the WLC.

Correct answer: B

Explanation

The correct answer is B because the eping command on the WLC is specifically designed to test the connectivity of the control and data tunnel. Options A and C involve Telnet connections on ports that are not relevant for debugging the mobility tunnel, while option D, using the mping command, is not appropriate for this particular scenario.
