Catalyst switches offline

[merakiuser3]

I have a number of Cisco 9300 Catalyst switches that I've been trying to onboard for monitoring but cannot get them to appear as "online" on the dashboard. All of the pre-onboarding steps have been followed, and connectivity to Meraki is open. 

* one C9300-24P running 17.03.04 - onboarded and came up on the dashboard. Using the upgrade firmware tool, I upgraded the firmware to 17.09.04a. The switch stayed online for a few days and then went offline on the dashboard.

* Three different C9300-48UXM running 17.03.04 - onboarded to the dashboard but remain offline on the dashboard. 

Has anyone experienced this and found a workaround?

Hi @merakiuser3 , if you’ve had them registered and then de-register I would first check your upstream firewall to see if any traffic is being blocked.  If that returns a blank reach out to Meraki support for direct assistance

Thanks for the suggestions. Yes, tried registering and de-registering them. Confirmed firewall is not blocking traffic, plus one switch was being monitored fine for almost a week. 

Already opened a ticket with Meraki support but they've been silent for a few days which is why I'm checking with the community to see if anyone has experienced this issue

Hi @merakiuser3 , quick tip….if you require a quicker response give them a ring if you haven’t already . I find support more responsive over the phone

As Darren suggested - pick up a phone and call Support;  it's better in almost every way.  If you already have a case open, quote the case reference to them.
