6 M1000e FlexAddress enablement
When working with network adaptors that provide a MAC address as well as a World Wide Port and
Node name, it’s important to understand where these addresses originate. The M1000e chassis has a
feature called Flexaddressing which allows for a virtual MAC address/WWPN to be linked to a server,
therefore, if the CNA/adapter is changed later, zoning or configuration on upstream switches does not
need to be modified.
Flexaddressing is a pool of 208 MAC’s and 64 WWN contained on an SD card that can either be added
at the Dell factory to the M1000e’s chassis management controller (CMC) or to an existing M1000e
CMC at a datacenter via a customer kit. Referring to Figure 72 below, enabling Flexaddressing is
facilitated by:
