Solved: MX LAG

hello,

Can I configure LAG on an MX into an SG switch? or does it only work on MS?

thanks

Link aggregation / LACP / 802.3ad is not supported on the MX. You can still set up dual uplinks to your MX but plan on using the fact that MXs forward STP BPDUs, to enable the switch network to block / unblock links as needed to resolve loops and restore connectivity in the event of a failure.

MX doesn't support LAG.

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

Please, if this post was useful, leave your kudos and mark it as solved.

LACP isn't supported on the MX. But there are topologies that Meraki recommends with Spanning-Tree:

You can find them in their documentation:
