Fibre Channel over IP (FCIP) is a tunneling protocol used to connect FC networks across IP networks, such as a WAN. It uses TCP with the DF bit set. Being that this is IP storage, it is only supported on the MDS platform. The basic configuration is straight forward, but be aware that there are lots of configurable tweaks. In this blog post I’ll be going through the configuration of several FCIP topologies, feel free to follow along. At the end I’ll post a quick template.
When first looking at the blueprint for the CCNA/CCNP/CCIE Data Center track, one of my biggest fears was storage. My entire career thus far has been based on traditional IP data networks, not storage networks. I’m used to things like MAC addresses and IP addresses, not WWPNs and FCIDs. This is a completely foreign technology to most Network Engineers. You have to think back, at some point we were young and hopeful CCNAs-to-be, we knew nothing, but that didn’t stop us! Intimidation is over-rated, so throw fear aside and know that persistence always wins.
So you’ve read all about FC, and now you want to see how to configure it. In this blog post I’ll be going through a basic FC configuration, covering some fundamental Fibre Channel topics along the way, such as:
