Betreff: Re: CSM MismatchRemoteDevice

Hi,

I have pages of those on a newly expanded cluster (was 6 nodes, now 10 for a tech refresh).
CDP is enabled all over, and “net device-discovery show” shows good data.
Currently 9.5P12.

I do have one of the ports down (bad cable, RMA taking 4+ days) so perhaps that is why?
