Hello @Enzo0112 

You can use as best practice 2 × 10 GbE and 2 × 1 GbE Separated, separate pair of physical 1 GbE adapters for VM traffic that must be isolated to another adapter or physical switch. Keep the CVM traffic on the 10 GbE network. You can place user VM traffic on either the 10 GbE network or the 1 GbE network. Compatible with any load balancing algorithm.

Hello @Moustafa Hindawi,

Thank you for your response.

My copper port and fiber SFP are both 10GbE, according to my check. 

Additionally, we only use SFP ports. There’s just another thing that concerns me now, is there an additional configuration to use the both copper port and the fiber SFP? 

Just to give you an idea, we are preparing to do maintenance on the SFP switches, which will result in a network failure. In order to prevent a scenario in which the network link fails, we are considering whether it is possible to use the copper ports to maintain the link.

Thank you!

I quote: 

• Don't mix NIC models from different vendors in the same bond.

• Don't mix NICs of different speeds in the same bond.

You should use leaf/spine network setup to mitigate switch failures. When doing switch maintenance do 1 switch at the time. 

As @JeroenTielen said connect each SFPs to 2 TOR switches, and maintain one switch at time.
