Hi All Network Guru. I have just setup 3 stacked MS225 switches and it has a single uplink to a FS core switch. I decide to setup a dual uplink for redundancy purposes and so I went ahead and configured 2 aggregate port on the Meraki (port26 on switch27 and port 49 on switch 29) and FS end. But as soon as I switch from the single uplink and connected to the aggregate port on the Meraki end, the entire stacked went offline. I am wondering if this is because BPDU guard is enable on the Meraki end? I am trying to get some idea where I can start troubleshooting and what is likely the cause of it so any pointers will be greatly appreciated! Whereas Over at the FS end I realize that the BPDU guard is disable I read from the community forum and I understand that for uplink it is better to enable loop guard instead, as BPDU guard are enable on the access and client end to prevent spanning tree
