Information About Domains
You must create a domain for the Cisco Nexus 1000V and then add control and packet VLANs for communication and management. This process is part of the initial setup of the Cisco Nexus 1000V when you install the software. If you need to create a domain later, you can do so by using the setup command or the procedures described in this chapter.
Layer 3 Control
Layer 3 control, or IP connectivity, is supported between the Virtual Supervisor Module (VSM) and the Virtual Ethernet Module (VEM) for control and packet traffic. With Layer 3 control, a VSM can be Layer 3 accessible and can control hosts that reside in a separate Layer 2 network. In the Layer 3 mode, all the VEMs hosts that are managed by VSM and the VSM can be in different networks.
Starting with Cisco Nexus 1000V for VMware vSphere, Release 5.2(1)SV3(2.1), you can configure IPv4 or IPv6 as transport mode for communication between VEM and VSM. A new option, l3v6, is introduced in the svs mode command to enable IPv6 transport mode.
To implement Layer 3 control, you must configure the VSM in Layer 3 mode.
