NSX-T Networking and Security
NSX-T is the networking and security platform used in
VMware Cloud on Dell
to create and manage
internal SDDC networks. If your SDDC version is 1.16 or later, the
Networking & Security
tab is unavailable.Log in to NSX Manager to manage your SDDC networks.Networking & Security
Tab
NSX-T provides a full set of logical network and security services decoupled from the
underlying physical infrastructure. Distributed functions such as switching, routing,
and firewalling not only provide L2 extension capabilities but also enhanced distributed
networking and security functions.
For security purpose, the logical network is
separated into management network and workload network. All the management components,
such as vCenter and VMware NSX® Manager™ reside on networks connected to the Management
Gateway (MGW) and VMware manages these components. You are not allowed to deploy
workloads on the management network through MGW. You must create NSX network segments
that are automatically connected to the Compute Gateway (CGW) and deploy your workloads
on these network segments.

VMware Cloud on AWS Networking and
Security
document.Reserved Network
Addresses
Certain CIDR ranges are unavailable for
use in SDDC compute networks. Several are used internally by SDDC network
components. Most are reserved by convention on other networks as well.
