MX LAG

[P4ck3ts]

hello,

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

thanks

MX doesn't support LAG.

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.

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

You can find them in their documentation:
