An overlay segment is a layer 2 broadcast domain that is implemented as a logical construct in the NSX-T Data Center software. Overlay segments do not require any configuration on the physical switches, and they allow for optimal east/west communication between workloads on different ESXi hosts. Overlay segments use the Geneve protocol to encapsulate and decapsulate traffic between the hosts. Overlay segments are created and managed by the NSX Manager.

The ifconfig command is used to display the network configuration of interfaces, including the Tunnel Endpoint (TEP) IP on a bare metal transport node. This command provides details about IP addresses, subnet masks, and other network settings for each interface on the node.

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.

Core Files should be excluded when collecting support bundles through NSX Manager because they may contain sensitive information, such as memory dumps that could reveal sensitive data from processes at the time of an issue. Excluding core files helps ensure that potentially sensitive data is not unintentionally shared.
