I am re-installing (wipeconfig, new software first, yada, yada) an AFF-A300 nodes and hit something new. I exit out of the setup at the (join / create) and turn on cdp (system node run -node localhost -command options cdpd.enable on) to validate as-built cabling matches expected/design. The two AFF A300 nodes are showing lldp entries from three different cisco devices, but not any cdp entries for any device. AFF-A300 running 9.14.1P5 (chosen to match FAS8200 cluster it will be eventually joining.) The destination cluster pair of FAS8200s are connected to the c2921(light out management) and N5K data switches, and are receiving/sending CDP advertisements without issues. So, all roads point to AFFs/ONATP as culprit. Yes, each AFF can ping the cluster LIFs of the other node, both nodes rebooted.
It may be that nodes must be fully baked into a cluster before cdp actually works?
It may be something with this version and patch of ONTAP as fresh install, so OS change?
No technical case opened, yet, sharing the love first.
Will update when solved.
