Recently I came across while working with NSX EDGE node error/alarm with configuration state is “Mismatch” as per below screenshot

Note: This error is due to the SSH enabled directly from the vCenter console rather enabled via NSX edge node settings and nothing to panic about it 🙂
To fix the above error/alarm, click on the Mismatch

Click Resolve. Alarm should go away in few minutes post UI refresh
if still not resolved then click on the radio button vSphere/Edge Applianceas shown below

Click Resolve. Alarm should go away in few minutes post UI refresh
Post alarm is cleared
