CCIEZone. com Methods for connecting FEXs. If youre wondering what an FEX is, check out this article http www. FEXs are connected to the parent switches via fabric interfaces. These are 1. Gbps interfaces which connect the two switches think of a stacking cable on a 3. There are two methods of configuring fabric interfaces Static pinning. Ether. Channels. Although these are somewhat differentiated in some of the documentation, the static pinning looks almost the same as that used for Ether. Channels.   The main difference is that static pinning uses physical interfaces, whereas Ether. Channel uses a single Port Channel interface for the fabric interface there are some minor configuration differences and requirements as shown below. Dynamips For Windows 7' title='Dynamips For Windows 7' />Take a look at two fabric interface configuration examples. The first is using an Ether. Channel, the second capture is using static pinning. Ether. Channel. The following diagram shows a representation of the connectivity and configuration of using an Ether. Channel for the fabric interface. Were only using two 1. Gbps interfaces in this example, but we could use up to four 1. Gbps interfaces using all of the 1. Gbps interfaces on the N2. Dynamips For Windows 7' title='Dynamips For Windows 7' />T.

Channel, yet the physical interfaces in the Ether. Channel bundle are shown. Note also that the pinning mode for both examples is listed as static. Whether we use an Ether. Channel or physical interfaces static pinning, the pinning mode is always static. This is why I mentioned that they both look virtually identical. There are some definite requirements for using an Ether. Channel for FEXs, such as the FEX parameter pinning max links must be set to 1. Conclusion. This is pretty basic article, but it shows some of the differences between the methods of configuring fabric interfaces between a Nexus 5. Nexus 2. 14. 8T.   In some future articles were going to explore some of the behaviors of NX OS with FEXs. Safety Trustworthy.
