Hello,
First off, I’m very new to Mikrotik, so I apologize if this is already answered somewhere.
I’m Just curious if the new MLAG in v7 requires exact identical models, and is this included in SwOS 7? (I have a CRS317-1G-16S+RM and a CRS326-24S+2Q+RM and would love to connect this in MLAG).
Are you running SwitchOS or RouterOS on your Devices?
I know RouterOS ver.7+ Supports MLAG.
SWOsS i don’t know !
To answer your original Question:
No , you don’t have to use identical Models.
Even in the Wiki, they don’t use identical models for their Exemple =)
