I have been tasked with configuring an Arista 7160 switch for RDMA. I am looking for any hints/tips/advice on what commands are needed so it runs efficiently. This is so far what I have been able to deduce from all the research I have done that I might possibly maybe need. Please let me know where I have strayed from the right path.
