Swicth down

[nst1]

I have a network meraki with several switches today I saw that two swtches lost connectivity as if they had been disconnected from the electrical power or disconnected the network cable.

What can I check ???

Also in one of the teams says there was a change in the topology that is due ??

What does the event log for the switch say?

[nst1]

it is the port of uplink of the switch

Well, that confirms the port went down/up.  What about the log for the other switch that it plugs into?

Have you got anyway of verify the switch is operating physically? 

Either way is looks like the ports is going up and down, maybe try a different switch port and see if the issue goes away.

You can hover your mouse over the green connectivity status bar to confirm if it was a power outage or not.  I don't understand your second question.
