We have several different Meraki APs including MR52s. Our MR52s were all connected with two cables in an LACP aggregation to HP 3800 switches. Last week over one night, all LACP trunks failed to the APs on all switches to all MR52s. The same thing happened to all of our MR52s at our other site a few days later.
I have had to disable the second port on all of these APs because even though STP disables one of the ports, I get an error saying the AP has trouble connecting to the Meraki cloud. Whatever I do, I cannot bring the trunk back up. The switch error is Not receiving any LACP BPDUs on port x/xx,bringing down port.
I'm presuming it's a a Meraki issue as it affected all our switches in the same evening, auto firmware updates are off so not sure what could have happened. Any ideas?
Hi, I have rebooted the APs, I have even upgraded the firmware from 25.13 to 26.8.1 at one of the locations.
The only other changes on the network were that we swapped out the Fortigate firewalls at each location for newer models and the gateway and DHCP for the Meraki management VLAN is on theses devices (The swap was about 2 days before one site was affected and around 6 hours before the other site) but not sure how this could affect them.
I'll see if I can get some port mirroring set up on the switch to see if I can see the LACPDUs - difficult to get on site at the moment though.
