Which command would allow you to verity receipt of a CoA message on an AOS...

The Change of Authorization (CoA) messages are used in network access control scenarios and are typically received by the network access server, in this case, an Aruba AOS 10 Gateway. The correct command to verify the receipt of a CoA message is related to the control path traffic because CoA is a control plane function.

Option B,packet-capture controlpath udp 3799, is the correct answer because it specifies capturing control plane traffic on UDP port 3799, which is the standard port for CoA messages.

Options A, C, and D are incorrect because:

Option A captures data plane traffic, not control plane traffic.

Option C'spacket-capture interprocess udp 3799does not refer to a standard command for capturing CoA messages.

Option D,tcpdump host-port 3799, does not specify the correct syntax for capturing traffic on Aruba devices.
