Network segments are logical networks for use by workload VMs in the SDDC compute network.
- A routed network segment (the default type) has connectivity to other logical networks in the SDDC and, through the SDDC firewall, to external networks.
- An extended network segment extends an existing L2VPN tunnel, providing a single IP address space that spans the SDDC and an on-premises network.
- A disconnected network segment has no uplink, and provides an isolated network accessible only to VMs connected to it. You can also create them yourself, and can convert them to other segment types.
See VMware Configuration Maximums for limits on segments per SDDC and network connections per segment.
A Single Host Starter SDDC is created with a single routed network segment named sddc-cgw-network-1
. Multi-host SDDCs are created without a default network segment, so you must create at least one for your workload VMs. When you create a segment, you start by configuring some basic parameters and specifying how DHCP requests are handled on the segment. After the segment has been created, you can take additional, optional steps to specify a segment profiles and create DHCP static bindings.
Procedure
What to do next
After a segment has been created and has a status of Success, you can click VIEW STATISTICS to view statistics for network traffic to and from the segment. You can click VIEW RELATED GROUPS to see a list of groups that include this segment. For more information about groups in NSX-T, see Add a Group in the NSX-T Data Center Administration Guide.
