VMware recommends setting the MTU (Maximum Transmission Unit) to 1700 or greater for NSX deployments. This is to ensure that the VXLAN encapsulation, which adds overhead to the original Ethernet frame, can be accommodated without fragmentation. This MTU requirement includes the entire data center network, including inter-data center connections, to ensure consistent communication across all network components involved in the NSX deployment.

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.

To configure a firewall rule based on the domain name of a specific application, the administrator needs to use the Profile field in a distributed firewall rule. The Profile field allows the administrator to select a context profile that contains one or more attributes for filtering traffic. One of the attributes that can be used is Domain (FQDN) Name, which specifies the fully qualified domain name of the application. For example, if the administrator wants to filter traffic to *.office365.com, they can create a context profile with the Domain (FQDN) Name attribute set to *.office365.com and use it in the Profile field of the firewall rule.

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.
