AHV Basics – Part 2 Network Segmentation



This is NOT an AHV only feature (ESXi and Hyper-V too) but a relevant follow up to the last post.

Network segmentation is a security feature introduced in AOS 5.5 that separates management traffic from backplane traffic by creating separate virtual networks, one for each of these traffic types, on the default external virtual switch on each host. To enable the CVMs in a cluster to communicate over these networks, the CVMs are multihomed. Multihoming is facilitated by the addition of a virtual network interface card (vNIC) to the CVM and placing the new interface on the backplane network. Additionally, the hypervisor is assigned an interface on the backplane network.
