Meraki APs - Interface (apr0, apr1) state shows as critical

Hello good people,

I have a question that I've had about Meraki APs node's statis in the NPM for a while.

We have many meraki AP node's state that will change to critical when an node's interface state changes to critical. The interface name that's shown in the node's details apr0 and apr1, which I assume is (2.4Ghz and 5.0Ghz networks), only show that the 'interface's downtime' is critical but when I check the Meraki dashboard all is well. Why is that? Where is this status being pulled from? How can I clear this critical state and update the node to show as 'up'?

Thanks in advance for your help all!

It sounds as if you have added the individual APs as standalone SNMP objects as well as via the Meraki API. We just use the API and don't see that "interface status" so I'm wondering if you have some sort of resource clash or similar.

@stuartd I don't see the API added to our SW dashboard. Sounds like I need to suggest we use the API vs the SNMP objects because the ciritcal state's don't correlate to Meraki's statuses. Thanks for your input!

Can you see if there are any events recorded for that interface / node?

Checked and there's no alert for that interface.

But, I was able to speak to a SolarWinds expert and the 'interface downtime' widget is tied to the node interface(s) discards/errors/loss, etc. And since the polls are 9/min increments and based on the threshold settings, the interface may show as 'critical' based on discards/errors/loss until there's a period where the errors/discards/loss have not surpassed the thresholds.

Here was the fix: Change the interface's thresholds from 'Single poll' to 'X out of Y polls'

i.e.: When you're within the node's interface page, edit node > node thresholds >

1. Override the general thresholds

2. And in the 'Warning' and 'Critical' thresholds, edit the 'Single Poll' dropdown to 'X out of Y polls'

I have it set to 5 out of 10 polls greater than 'X' amount of errors per hour and that cleared the critical status

Can you really see discards / errors on this interface? In one of my cases I can see this:

Still this interface is Up, maybe because it has not passed the thresholds (1000/hour for Warning, 2500/hour for Critical).

The setting you mention is at node level, not interface level. At interface level I don't see drop-down with Single-Poll

You do have transmit errors but no critical status. Here's where the setting is to override the thresholds. I drill down in the node and select the interface that is 'critical', then you should see 'edit interface' in the interface details:
