Mention in the discussion of the link below.
"Link Aggregation/EtherChannel/Port-Channel uses different methods of bundling multiple ethernet links into one logical link. Link Aggregation (LACP), Port Aggregation Protocol (PAgP) or "mode on". The terminology is often used interchangeably to describe link bundling. For example, certain Cisco platforms (Catalyst) use the command "show etherchannel summary" while some (Nexus) utilize "show port-channel summary". In short, they are referencing the same feature.
Meraki MS supports LACP only which means that both ends of the link(s) should be able to talk 802.3ad. "

I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.
