The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter contains the following sections:
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 a Cisco Nexus 1000V when installing 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, 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 ) managed by VSM and the VSM can be in different networks.
Another VSM cannot control a host that is outside of the Layer 2 network it controls, the host on which it resides must be controlled by another VSM.
To implement Layer 3 control, you must make the following configuration:
Parameter |
Default |
---|---|
Control VLAN (svs-domain) |
VLAN 1 |
Packet VLAN (svs-domain) |
VLAN 1 |
VMware port group name (port-profile) |

Configuring the Domain
You can create a domain name for the Cisco Nexus 1000V that identifies the VSM and VEMs; 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 installing the software. If you need to create a domain after initial setup, you can do so by using this procedure.
Note |
We recommend the following:
|
Before beginning this procedure, you must be logged in to the CLI in EXEC mode.
You must know the following information:
switch# config terminal switch(config)# svs-domain switch(config-svs-domain)# domain id 100 switch(config-vlan)# exit switch(config)# show svs domain SVS domain config: Domain id: 211 Control vlan: NA Packet vlan: NA Control mode: L3 Switch guid: 20ccba13-3738-60db-b077-91a774b41eda L3 control interface: mgmt0 Status: Config push to VC successful. Control type multicast: No Note: Control VLAN and Packet VLAN are not used in L3 mode switch(config)# switch(config)# copy run start [########################################] 100% switch(config)#
This procedure requires you to disable the control and packet VLANs. You cannot change to Layer 3 Control before disabling the control and packet VLANs.
Before beginning this procedure, you must be logged in to the CLI in EXEC mode.
You have already configured the Layer 3 interface (mgmt 0 or control 0) and assigned an IP address.
