R720 Not Discovering ZD1200 Over L2
R720 isn't discovering our ZD1200 over L2. Not much else to describe. Not even seeing any traffic logs of it even attempting to talk to the ZD1200.
All I've done on the ZD1200 is set it up with an IP, DNS, and NTP settings.
I see the R720 talking with our DNS and some outside IPs, but nothing else. So I thought maybe we needed a DNS record, so I added a zonedirector.our-domain.com. Still nothing.
The R720 is pulling an IP. I can access its management page. I could set up everything manually, but I'd rather not.
What am I missing?
