My customer has ESXi servers with 2 CNA cards connected to Nexus 5K upstream switches. We will be using the 1000v for the Ethernet portion. Question is, what are QOS options for dividing bandwidth between FCOE and Ethernet traffic? Is there a default split?
Thanks,
John

USe predefined policy maps. It matches frames with cos 3 and allocates 50% bandwidth for FCoE traffic and sets 2158 MTU to FCOE queue. If you are using Nexus 5000 it will automatically apply these policy-maps automatically when you enable feature fcoe.
