Thanks, yeah it should work with autonegotiate.
Hello,     we have installed VxRail P670F using 10G ports (2* 10G NDC ports) now we are upgrading our switches to 25G speed ports and need to use 4*25G ports (NDC+PCI) i can found steps to move from 2 to 4 Ports but actually my Questions    does changing ports speed (PowerDown the Cluster / change switches then power up) need special configuration or the ports are auto-negotiated no special action is needed? 
Move from 10G Port's Speed to 25G Port's Speed
