Configuring the Software Using the GUI
This chapter describes how to use the GUI application to complete the Cisco Nexus 1000V configuration, and includes the following sections.
•
GUI Software Configuration Process
•Setting Up a Primary or Standalone VSM VM Using the GUI
•Setting Up a VSM with a Copy of a Configuration File
Information About the GUI Application
You can use the GUI application, after the software is installed, to complete the following Cisco Nexus 1000V configuration for a standalone, or primary and secondary VSM. The GUI application uses the options you chose during VSM installation to determine which configuration steps are required.
•Create port profiles for the Control, Management, and Packet port groups:
•Create uplink port profiles.
•Create port profiles for VMware kernel NICs.
•Specify a VLAN to be used for system login and configuration, and control and packet traffic.
Note You can use the same VLAN for control, packet, and management, but if needed for flexibility, you can use separate VLANs. If you use the same VLAN, make sure that the network segment where it resides has adequate bandwidth and latency.
•Enable Telnet and SSH and configure an SSH connection.
•Create a Cisco Nexus 1000V plug-in and register it on the vCenter server.
•Migrate each VMware port group or kernel NIC to the correct port-profile.
•Migrate each PNIC from the VMware vSwitch to the correct uplink on the DVS.
•Add the host to the DVS.
Note If you install the Cisco Nexus 1000 in a VMware cluster with DRS enabled, all ESX hosts must be migrated to the Cisco Nexus 1000 DVS. If only some hosts are migrated it is possible that VMs could be installed or moved to hosts in which the vSwitch is missing VLANs, physical adapters, or both.
•Save the configuration to a file as a backup or for use as a template in creating subsequent VSMs.
GUI Software Configuration Process
The following section will guide you through this process. After completing each procedure, return to this section to make sure you complete all required procedures in the correct sequence.
Step 1 Set up the primary or standalone VSM virtual machine using the "Setting Up a Primary or Standalone VSM VM Using the GUI" procedure.
Step 2 Set up the secondary VSM virtual machine using the "Setting Up a Secondary VSM" procedure.
Step 3 Do one of the following:
•If you have purchased licenses, add them to the Cisco Nexus 1000V using the following document:
–Cisco Nexus 1000V License Configuration Guide, Release 4.2(1)SV1(4)
•If you are using the temporary licenses provided in the software, then continue with the next step. No action is required.
Note The software provides licenses for 16 CPU sockets for a period of 60 days. These licenses are used only if there are no permanent licenses installed on the VSM. The evaluation period of 60 days starts when you install the software.
Step 4 Set up the additional VSM virtual machines using the "Setting Up a VSM with a Copy of a Configuration File" section.
Step 5 You have completed this process. Return to the "Software Configuration Process" section on page 2-7 to continue setting up your VSM software.
Guidelines and Limitations
This configuration process has the following guidelines and limitations:
•To prevent a disruption in connectivity, all port profiles are created with a system VLAN. You can change this after migration if needed.
•For a complete list of port profile guidelines and limitations, see the Cisco Nexus 1000V Port Profile Configuration Guide, Release 4.2(1)SV1(4).
•The host and adapter migration process moves all PNICs used by the VSM from the vSwitches to the Cisco Nexus 1000V DVS.
•The following must be in place if you migrate the host and adapters:
–The host must have one or more physical NICs on each vSwitch in use.
–The vSwitch does not have any active VMs.
To prevent a disruption in connectivity during migration, any VMs that share a vSwitch with port groups used by the VSM must be powered off.
–The host must use a VUM-enabled vCenter server.
–You must also configure the VSM connection to the vCenter server datacenter where the host resides.
•The migration process supports Layer 2 and Layer 3.
•No VEMs were previously installed on the host where the VSM resides.
Host management connectivity may be interrupted if VMware kernel 0, vSwitch interface 0 are migrated and the native VLAN is not correctly specified in the setup process.
•The following modification is required to the uplink port profile created by the GUI application if you are installing Cisco Nexus 1000V in an environment where the upstream switch does not support static port channels, such as UCS. The GUI application creates the uplink port profile with channel group auto mode on which must be changed to:
channel group auto mode on mac-pinning
This change is required before adding VMNICs in the DVS using this profile.

Setting Up a VSM with a Copy of a Configuration File
You can use this section and a configuration file to set up a VSM.This section includes the following procedures:
•"Preparing a Configuration File" procedure
•"Example Configuration File" section
•"Applying the Configuration File" procedure
Preparing a Configuration File
You can use this procedure to create a new VSM by editing a copy of the configuration file exported while creating another VSM.
BEFORE YOU BEGIN
Before beginning this procedure, you must know or do the following:
•You have saved a previous VSM configuration to file and you know the location of this file.
•You have the following information about the new VSM you are creating:
–Datacenter name
–Virtual Machine name
–Virtual switch port group name(s)
You can use the same port group for management, control, and packet; or you can specify separate port groups.
Note Port group names must match those in the vSwitch of the ESX host where the VSM is installed.
–Layer 3 interface and VLAN ID
This information is only needed if you are configuring Layer 3 connectivity.
–Host name
–Management IP, subnet mask, gateway IP
–Domain ID
–SVS connection datacenter name
–HA role
–Native VLAN ID
This is the upstream switch native VLAN for the physical NIC which will be added to the DVS. The native VLAN is used only if you are migrating your configuration.
DETAILED STEPS
Step 1 In a text editor, open the configuration file you intend to use as a template.
This will be a file you exported from a previous VSM configuration. You will edit this file using the following steps.
Step 2 Add the name of the datacenter where your VSM resides.
Example:
# The datacenter name
Datacenter=AutomationDC
Step 3 Add the name of the VM for your VSM.
Example:
# The virtual machine name
VirtualMachine=upgrade1
Step 4 Do one of the following:
•Go to Step 5 to configure one VLAN (the management VLAN) for use in the control, management, and packet port profiles.
•Go to Step 6 to configure a VLAN for each port profile separately.
•Go to Step 7 to configure Layer 3 connectivity.
Step 5 Specify that you are using the basic configuration.
In this case, you are configuring the management VLAN for use in the control, management, and packet vSwitch port groups.
Example:
# Basic: All on preconfigured Management Port Group. No other config necessary
NetConf=Basic
The port group assigned to the VSM mgmt interface is now also assigned for control and packet and the VSM VM is reconfigured to use the same port group for mgmt, control, and packet.
Go to Step 9.
Step 6 Specify that you are configuring a VLAN for each port profile separately; and then add the VLAN IDs for this VSM.
Example:
# Advanced: Must specify Control/Management/Packet
NetConf=Advanced
# Port group names (names must match the name in the VC)
Control=control-portgroup
Management=management-portgroup
Packet=packet-portgroup
Go to Step 9.
Step 7 Specify that you are configuring Layer 3 connectivity.
Example:
# L3: Must specify L3Interface/Control/Management
NetConf=L3
Step 8 Do one of the following:
•Specify VSM to VEM communication over the VSM control interface and control port group. Then add the port groups and IP addresses.
Note Control and management IP addresses must be in different subnets. This command will fail if the control and management IP addresses are not in different subnets.
Example:
# L3Interface (2 options): control0/mgmt0
L3Interface=control0
Control=control-portgroup
Management=management-portgroup
L3Vlan=233
ControlIpV4=192.168.0.100
ControlIpV4Subnet=255.255.255.0
ControlIpV4Gateway=192.168.0.1
•Specify VSM to VEM communication over the management interface. The control portgroup will still be used for VSM HA. Then add the port groups and VLAN ID.
Example:
# L3Interface (2 options): control0/mgmt0
L3Interface=mgmt0
Control=control-portgroup
Management=management-portgroup
L3Vlan=233
Step 9 Add the following information for this VSM:
•Host name
•Management IP, subnet mask, Gateway IP
•Domain ID
•SVS connection datacenter name
•Whether to enable Telnet.
Example:
################
# VSM Config #
################
HostName=configSwitch
ManagementIpV4=172.23.233.64
ManagementIpV4Subnet=255.255.255.0
GatewayIpV4=172.23.233.1
DomainId=470
SvsDatacenter=AutomationDC
#EnableTelnet: True/False
EnableTelnet=True
Step 10 Add the HA role (standalone or primary) for this VSM.
Example:
#HARole: standalone/primary
HARole=standalone
Step 11 Add the native VLAN for this VSM.
Example:
#NativeVlan: native vlan ID
NativeVlan=233
Step 12 Save the configuration file.
You have completed this procedure.
