Which WLC command tests mobility EoIP data packets?
An engineer is planning a wireless deployment with two members in a mobility group. The engineer notices that there are issues establishing the mobility tunnel. The engineer must test the mobility EoIP data packet communication between two controllers. Which command runs this test?

Community Insight
The exam tests the specific AireOS command for mobility EoIP data-path validation, and the trap is selecting mping simply because it contains 'm' for mobility.
In a Cisco WLC mobility group, EoIP data packet communication between controllers is tested with the eping command. This page confirms eping (B) is the correct command and explains why mping and the debug options do not perform that data-path test.
Learners often choose mping because its name suggests a mobility tunnel test, but mping exercises mobility control messaging rather than the EoIP data packets the question asks about.

Expert Analysis
Why the Answer Is Correct
The question asks which command tests mobility EoIP data packet communication between two controllers in a mobility group. In Cisco AireOS WLC CLI, eping is the Ethernet ping command that sends an EoIP probe to the peer controller and validates the data path used by the mobility tunnel. Because the failure is described as an issue establishing the mobility tunnel and the requirement is specifically to test EoIP data packets, eping is the correct diagnostic command. This aligns with the community consensus that eping is the command for mobility data over EoIP.Why the Other Options Are Wrong
debug route is a routing diagnostic and does not generate EoIP mobility packets. debug icmp can help trace ICMP traffic, but it does not actively test the mobility EoIP data path between controllers. mping may sound like the right choice because of its mobility-related name, but it is not the EoIP data packet test the question requires. Only eping directly performs the EoIP data communication test needed to troubleshoot the mobility tunnel.Community Comment Notes
All visible commenters — Jonycici, Farhad123, and Nerdx1 — selected B and agree that eping is correct. Jonycici and Farhad123 both wrote "eping is the correct answer", reinforcing the source key. Nerdx1 provides the technical reason, noting that "eping tests mobility data over EoIP". No commenter argued for mping, debug route, or debug icmp, so there is no community dispute about this command.Exam Strategy
Memorize the AireOS mobility verification commands by layer: eping for the EoIP data tunnel and mping for mobility control communication. When a question mentions EoIP data packets, choose eping without being distracted by the more obviously named mping.
Frequently Asked Questions
Why is mping not the correct command for testing mobility EoIP data packets?
mping is not the EoIP data-path test; the question specifically requires validating mobility EoIP data packet communication, which eping performs between controllers.
What does eping test in a Cisco WLC mobility group?
eping sends an Ethernet ping over the EoIP tunnel to a peer controller, verifying that the mobility data path is operational between mobility group members.
