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.
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)
Great blog by Kevin Wallace on EIGRP timers https://kwallaceccie.mykajabi.com/blog/understanding-eigrp-part-3-eigrp-timers
To ensure you have HA, from your access switches have one etherchannel uplink from the top stack switch and another etherchannel uplink from the bottom stack switch.
In your wireless environment, spread your access points across all stack switches so if one switch is to fail, you haven’t lost complete wireless coverage. Position acccess points in a way to cater to this.
Great video from Kevin Wallace regarding accessing and setting yourself up to utilise the Cisco DevNet sandbox. Not many know that it exists. See Kevin’s video here https://youtu.be/QBqcncqEvBU
