To debug EIGRP use debug EIGRP packets as opposed to debug ip EIGRP events. EIGRP was originally designed to route multiple protocols including AppleTalk, IP version 4 (IPv4), IP version 6 (IPv6), and Novell Internetwork Packet Exchange (IPX), which is why the later debug command exists.
Kevin Wallace compares two SDN controllers, the Application Policy Infrastructure Controller (APIC) and the Application Policy Infrastructure Controller Enterprise Module (APIC-EM).
Great video by Kevin Wallace on the Introduction to Python and removing FUD (fear, uncertainty and doubt).
In Cisco IOS there are a few ways of filtering IOS output to show only the information you are searching for. For example when looking at the input and output packet counters on an interface you could do one of the below.
Show interface g0/14 | in packets input|packets output
Show interface g0/14 | in packets (input|output)
