Mellanox Cumulus Linux MTU

Infrastructure & Networking Switches and Gateways

I recently bought Mellanox SN2010 Cumulus Linux. Is there any recommendation from mellanox on how i must configure MTU on the ports for my 9000 bytes VMWare’s jumbo frames?

Or i should just go with 9216 bytes as it the max MTU that supported by mellanox.

Thanks

Hello Firman,

We would recommend to set the MTU on the switch to 9216 to allow COS and VLAN tags.

Thank you and regards,
