Brand new system arrived, built to basic level, cluster ports are up (not joined to cluster at this point yet), but I noticed in the network device-discovery show command its not showing the connectivity to my cluster switches and nothing under CDP, when I check the options on the node cdpd.enable is off, pretty sure this should be on for all nodes in any version of ONTAP for cluster ports, wanted to check to see if anyone had see this or had to change it before?
#cdpd.enable off

Hmm checking some of our other nodes (which I should of done first) it looks like this is off on all over them, so cant be that option being set to off

Our network team blocks CDPD. Apparently there is something about it that they consider insecure. So, we use LLDP instead. "options lldp.enable". That is not on by default, so maybe you have that enabled on your other clusters? We still keep CDPD enabled though, because that is what the NetApp switches use.

I think it depends on which cluster-switches you use. I remember somewhere in the release notes of the OS for these switches (or even RCF?) that they implemented/enabled LLDP because CDP was not supported. I think it was for the new Nvidia switches SN2100.
You could always simply enable it, there is no harm in that:
node run * options lldp.enable on```

CDP/LLDP is always enabled for cluster network ports. Can’t be turned off. (As far as I know). The options you see only affect data ports/non-cluster ports.

@dusk karma there have been many cdp bugs and the initial fix is to disable cdp. Usually it is followed by a code patch which makes it safe again but likely they just leave it off on the switches
