Last week I presented about 90 minutes focused on the Cisco UCS exam portions of the CCNP-DC:
- 642-999 Implementing UCS (and)
- 642-998 Designing UCS (or) 642-035 Troubleshooting UCS
What Exactly is FEX?

Native Fiber Channel and FCoE Tips
When you configure your WWNN and WWPN pools, use a fabric identifier in the hexadecimal address. The WWPN is a standardized notation, and the first three octets should not be modified as they are vendor-specific (underlined below). The last three, however, can be modified to whatever scheme you prefer, such as the one below:
- Template: 00:25:B5:[POD#]:[CHASSIS#][FABRIC]:[HBA#]
- Fabric A: 00:25:B5:01:2A:00
- Fabric B: 00:25:B5:03:1B:01
Finally, because native Fiber-Channel (2/4/8Gbps) ports must be selected in a contiguous group from the right-side of a chassis or module, it is often desirable (thanks Trevor for mentioning this—I had forgot about it!) to put native FC ports on the expansion module, since a reboot is required to make the changes take effect. If you do this, only the module will reinitialize, and the rest of the Fabric Interconnect will remain operational.
