logs show above massage on regular interval, uplink 36 and rest all port change the status.

I removed STP from dowlink 1-30 but still no impact.

Also some error on power supply. 

Data flow ->>>client (jumbo frame) >> Axis switch >> Meraki410>>Extreme L3 switch>>Net

any suggestion?

Maybe your device is (re)booting .. 

Power supply inserted, doesnt look good.

Are you using 1 or 2 power supply?

[Dinesh2]

I don't see any reboot, only 1 power supply. 

[ww]

Reboot doesnt show in the event log. 

I would suggest to create a support case

I'd second this, switch is rebooting and then ports are coming up.

Have you made any changes to the firmware version recently?

[Dinesh2]

New installation, Firmware is latest one

[Brash]

Are all of the switches in the chain configured for jumbo frames?

I don't know anything about Axis or Extreme switches but if it's a cut-through switch it could be flagging the frames as bad and passing them through the network.

[Dinesh2]

Yah, all switches are configured with Jumbo frames

@Dinesh2  Did you ever get to the bottom of this issue. What did Meraki support say?

We've been having weir issue all last week to do with some traffic not passing from VLAN A to VLAN B. Both on the same physical switch.

Then I noticed this when I looked at the switch event logs. This seems to be happening across the switches that we are having issues. The affected network has oly a single switch so shouldn't even have any RSTP issue.
