Delete WAN2

[D_King_GCT]

We have an MX84.  Prior to COVID, we installed an MG-21 cell phone backup because we were not satisfied with the uptime of our fiber connection.  When we upgraded our Fiber, it has been 100% rock solid, and we decided to depricate and remove the secondary backup ISP and the MG-21.  The one time the MG-21 tripped before the Fiber upgrade, it incurred thousands of dollars of cell traffic in a single afternoon.  The safety net was neither needed nor economical to maintain with our new ISP.

I disabled the WAN2 in Security & SD-WAN -> Monitor -> Appliance Status

I removed the device from our inventory in Organizational -> Configure -> Inventory, then selected "unclaim"

The Primary uplink is set to WAN1 under Security & SD-WAN -> Configure -> SD-WAN and Traffic Shaping.  Load Balancing is disabled, and Multi-Uplink VPN is disabled.

Everything is working as it should, but my "Network Health Score" constantly gives me a poor rating because WAN2 is down.

One other note, we are using a connection to AWS through a VPC to provide off-site backup and redundancy to our systems.

How does one delete WAN2 from the Meraki system?

You can't delete this. Are you receiving dashboard notifications?

Have you tried removing the dashboard alerts?

Has it been more than 30 days since you made the changes? That's the only reason I can think of. Essentially the calculation might be based on a longer period of time. You can't delete WAN2 on an MX84 (only 64/67/100 not sure about some of the super old models).

Support may be able to clarify, I don't see anything in the documentation I'm reading.

I have been ignoring the low score for months.   The MG21 was decommissioned on February 21, 2024.

I am not receiving alerts on the issue. The "Network Health Score" is one of the metrics I check every day to ensure our systems are running correctly.

There is no way to remove this, a possible "solution" I thought of is that you can connect a loopback adapter or a non-routable IP to WAN2 and then assign it a static IP with no gateway or DNS. This might make the panel think that WAN2 is "active" without actually routing traffic through it.
This is a workaround and is not officially supported, and to be honest I have never tried it.

Make sure the MG21 is unplugged from WAN2, so the Ethernet link is down.

Someone had plugged it back in 🙄.  Disconnecting it again immediately bumped my score up some in the network health monitor.  It still says down, but as Mloraditch hinted at, that could be an echo from the sampling time of the monitoring.  We'll see if it remains better.  In the meantime, the old MG21 is now on my workbench, not connected to the network.

I believe between this answer and Alemabrahao's response that one cannot remove the WAN2 configuration in the older MX models, I have my answer.

Thank you all.
