NSX Intelligence is a distributed analytics solution within the VMware NSX Portfolio that provides visibility and dynamic security policy enforcement in NSX environments. It enables detailed traffic analysis, identifies security threats, and helps in the automated creation and enforcement of security policies based on observed network traffic patterns and behaviors.

In an NSX environment with a Tier-0 Gateway configured in active-standby high availability mode, Destination NAT (DNAT) and Source NAT (SNAT) are supported NAT rule types. These allow for traffic redirection by modifying the destination or source IP addresses as needed, which is commonly used in configurations involving external access and internal IP address translation.

In an NSX environment, each overlay segment is uniquely identified by a VNI ID (Virtual Network Identifier). The VNI is used to distinguish different overlay networks within the NSX environment and is essential for troubleshooting, as it helps administrators identify specific segments where traffic is encapsulated and isolated.

esxcfg-nics -l: This command lists all physical NICs on the ESXi host along with their link status, allowing you to check if any vmnic link status is down.

esxcli network nic list: This command provides a list of network interfaces with their details, including link status, making it useful for verifying if the link status of a vmnic is down.

The Network Engineer role in NSX is a built-in role that provides permissions to apply configuration changes on NSX components, including NSX Edge. It is the most restrictive role that still allows users to make changes, whereas roles like Network Operator are typically limited to read-only access.

In NSX, Unicast traffic type should be used in TraceFlow when validating connectivity between two specific virtual machines, such as App and DB VMs, that reside on different segments. Unicast traffic is directed from one source to a single destination, making it suitable for testing direct connectivity between two VMs.

master: The master role in NSX Manager is responsible for managing and coordinating the other NSX Manager nodes in the cluster.

policy: The policy role handles the policy-driven API and configuration, allowing administrators to define and manage network and security policies.

controller: The controller role in NSX Manager manages control plane functions and handles routing, switching, and other network state information required for NSX operations.
