Refer to the exhibit. A flapping link issue has been reported on the vPC keepalive link. A packet capture has been activated on the Cisco Nexus switch. What is the destination IP address of the vPC keepalive packets that are sent by the switch?
Suggested Answer:A🗳️
3200 is the default UDP port for keepalive packets. Just look for the first line with port 3200 and note the destination IP, which is 192.168.254.4.

A is correct. The keepalive is between 192.168.254.3 and 192.168.254.4. Apparently, the other log entries are showing that 192.168.254.3 is local on the switch.
