Information About the Nexus 1000V Installation Management Center

The Nexus 1000V Installation Management Center is the graphical user interface (GUI) for installing the VSMs in high availability (HA) mode and the VEMs on ESX/ESXi hosts.

To prevent a disruption in connectivity, all port profiles are created with a system VLAN. You can change this after migration if needed.

The host and adapter migration process moves all physical network interface cards (PNICs) used by the VSM from the VMware vSwitch to the Cisco Nexus 1000V Distributed Virtual Switch (DVS).

The migration process supports Layer 2 and Layer 3 topologies.

The installer does the following:

  • Creates port profiles for the control, management, and packet port groups.
  • Creates uplink port profiles.
  • Creates port profiles for VMware kernel NICs.
  • Specifies 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 port groups, but you can also use separate VLANs for flexibility. If you use the same VLAN, make sure that the network segment where the VLAN resides has adequate bandwidth and latency.

  • Enables Telnet and Secure Shell (SSH) and configures an SSH connection.
  • Creates a Cisco Nexus 1000V plug-in and registers it on the vCenter Server.
  • Migrates each VMware port group or kernel NIC to the correct port profile.
  • Migrates each physical network interface card (PNIC) from the VMware vSwitch to the correct uplink on the DVS.
  • Adds the host to the DVS.

Prerequisites for Installing the Cisco Nexus 1000V

Nexus 1000V Installation Management Center Prerequisites


Note

The Installation Management Center requires you to satisfy all the prerequisites.

If you migrate the host and adapters from the VMware vSwitch to the Cisco Nexus 1000V DVS:

  • The host must have one or more physical NICs on each VMware vSwitch in use.
  • The VMware vSwitch must not have any active VMs. To prevent a disruption in connectivity during migration, any VMs that share a VMware vSwitch with port groups used by the VSM must be powered off.
  • You must also configure the VSM connection to the vCenter server datacenter where the host resides.
  • Host should have only one VMware vSwitch.
  • Make sure no VEMs were previously installed on the host where the VSM resides.
  • You must have administrative credentials for the vCenter Server.

Host Prerequisites

The ESX or ESXi hosts to be used for the Cisco Nexus 1000V have the following prerequisites:

  • You have already installed and prepared the vCenter Server for host management using the instructions from VMware.
  • SSH has been enabled.
  • You should have the VMware vSphere Client installed.
  • You have already installed the VMware Enterprise Plus license on the hosts.
  • All VEM hosts must be running ESX/ESXi 4.1 or later releases.
  • You have two physical NICs on each host for redundancy.
  • All hosts must have Layer 2 connectivity to each other.
  • If you are using a set of switches, make sure that the inter-switch trunk links carry all relevant VLANs, including control and packet VLANs. The uplink should be a trunk port that carries all VLANs configured on the host.
  • The control and management VLANs must already be configured on the host to be used for the VSM VM.
  • Make sure that the VM to be used for the VSM meets the minimum requirements listed in the following table.
  • All the vmnics should have the same configuration upstream.

Upstream Switch Prerequisites

The switch upstream from the Cisco Nexus 1000V has the following prerequisites:

  • If you are using a set of switches, make sure that the inter-switch trunk links carry all relevant VLANs, including the control and packet VLANs. The uplink must be a trunk port that carries all the VLANs that are configured on the host.
  • The following spanning tree prerequisites apply to the switch upstream from the Cisco Nexus 1000V on the ports connected to the VEM.
    • On upstream switches, the following configuration is mandatory: On your Catalyst series switches with Cisco IOS software, enter the following command: (config-if) spanning-tree portfast trunk or (config-if) spanning-tree portfast edge trunk On your Cisco Nexus 5000 series switches with Cisco NX-OS software, enter the following command: (config-if) spanning-tree port type edge trunk
    • On upstream switches we highly recommend that you enable the following globally: Global BPDU Filtering Global BPDU Guard
    • On upstream switches where you cannot globally enable BPDU Filtering and BPDU Guard, we highly recommend that you enter the following commands: (config-if) spanning-tree bpdu filter (config-if) spanning-tree bpdu guard
    For more information about spanning tree and its supporting commands, see the documentation for your upstream switch.
  • Run the following commands on the upstream switch:

Note

A standalone VSM is not supported in a production environment.

  • You are familiar with the Cisco Nexus 1000V topology diagram that is shown in Layer 3 Topology.

VEM Prerequisites

The Cisco Nexus 1000V VEM software has the following prerequisites:


Note

If the VMware vCenter Server is hosted on the same ESX/ESXi host as a Cisco Nexus 1000V VEM, a VUM-assisted upgrade on the host will fail. You should manually vMotion the vCenter Server VM to another host before you perform an upgrade.

  • When you perform any VUM operation on hosts that are a part of a cluster, ensure that VMware HA, VMware fault tolerance (FT), and VMware distributed power management (DPM) features are disabled for the entire cluster. Otherwise, VUM cannot install the hosts in the cluster.
  • You have a copy of your VMware documentation available for installing software on a host.
  • You have already obtained a copy of the VEM software file from one of the sources listed in VEM Software.
  • You have already downloaded the correct VEM software based on the current ESX/ESXi host patch level. For more information, see the Cisco Nexus 1000V and VMware Compatibility Information.
  • For a VUM-based installation, you must deploy VUM and make sure that the VSM is connected to the vCenter Server.

Guidelines and Limitations

Guidelines and Limitations of the Nexus 1000V Installation Management Center

Configuring the software using the Nexus 1000V Installation Management Center has the following guidelines and limitations:

  • For a complete list of port profile guidelines and limitations, see the Cisco Nexus 1000V Port Profile Configuration Guide.

    Caution

    Host management connectivity might be interrupted if the management vmknic or vswif are migrated and the uplink’s native VLAN is not correctly specified in the setup process.

  • If you are installing a Cisco Nexus 1000V in an environment where the upstream switch does not support static port channels, such as the Cisco Unified Computing System (UCS), you must use the channel-group auto mode on the mac-pinning command instead of the channel-group auto mode command.
  • We recommend that you install redundant VSMs on the Cisco Nexus 1000V. For information about high availability and redundancy, see the Cisco Nexus 1000V High Availability and Redundancy Configuration Guide.
  • If the Installation Management Center fails, check the vCenter Server event status. If an event shows failure due to a timeout, then it could be because of a vCenter Server overload. Please consult the VMware website to address a vCenter Server overload event.

Guidelines and Limitations for Installing the Cisco Nexus 1000V

Use the following guidelines and limitations when installing the Cisco Nexus 1000V software:

  • Do not enable VMware FT for the VSM VM because it is not supported. Instead, Cisco NX-OS HA provides high availability for the VSM.
  • The VSM VM supports VMware HA. However, we strongly recommend that you deploy redundant VSMs and configure Cisco NX-OS HA between them. Use the VMware recommendations for the VMware HA.
  • Do not enable VM Monitoring for the VSM VM because it is not supported, even if you enable the VMware HA on the underlying host. Cisco NX-OS redundancy is the preferred method.
  • When a user moves a VSM from the VMware vSwitch to the Cisco Nexus 1000V DVS, it is possible that the connectivity between the active and standby VSM is temporarily lost. In that situation, both active and standby VSMs assume the active role. Once the connectivity is restored between the VSMs, the VSM configured with the role of primary reloads itself and comes back as standby.
  • If the VSM is moved from the VMware vSwitch to the Cisco Nexus 1000V DVS, it is recommended that you configure the port-security on the VSM vethernet interfaces to secure control/packet MACs.
  • To improve redundancy, install primary and secondary VSM virtual machines in separate hosts that are connected to different upstream switches.

              Installing the VEM Software Remotely on a VMware 4.1 Host by Using the CLI

              Before You Begin
              • If you are using the vSphere command-line interface (vCLI), do the following:
                • You have downloaded and installed the VMware vCLI. For information about installing the vCLI, see the VMware vCLI documentation.
                • You are logged in to the remote machine where the vCLI is installed.

              Note

              The vCLI command set allows you to enter common system administration commands against ESX/ESXi systems from any machine with network access to those systems. You can also enter most CLI commands against a vCenter Server system and target any ESX/ESXi system that the vCenter Server system manages. vCLI commands are especially useful for ESXi hosts because ESXi does not include a service console.

              Procedure
                Step 1   Go to the directory where the new VEM software was copied. 
                [root@serialport -]# cd tmp 
[root@serialport tmp]#
                Step 2   Install the VEM software. [root@serialport tmp]# vihostupdate -i -b ./Cisco_updated_VEM_offline_bundle --server vsphere_host

                Example:
                [root@serialport tmp]# vihostupdate -i -b ./VEM410-201201401.zip --server 192.0.2.0 
Enter username: root
Enter password:
Please wait patch installation is in progress ...
Host updated successfully.
                Step 3   Verify that the VEM software is installed on the host. vihostupdate.pl -q --server host_ip_address

                Example:
                [root@serialport tmp]# vihostupdate.pl -q --server 192.0.2.1 
Enter username: root

                    Installing the VEM Software on a Stateless ESXi Host

                    The following list outlines the VEM installation process on a stateless ESXi host.

                    Procedure
                      Step 1   See the procedure for Adding the Cisco Nexus 1000V to an ESXi Image Profile.
                      Step 2   Installing the VEM software using one of the two following procedures:
                      Step 3   See the procedure for Configuring Layer 2 Connectivity.

                      Stateless ESXi Host


                      Note

                      For Stateless ESXi, the VLAN used for Preboot Execution Environment (gPXE) and Management must be a native VLAN in the Cisco Nexus 1000V management uplink. It must also be a system VLAN on the management VMkernel NIC and on the uplink.

                      VMware vSphere 5.0.0 introduces the VMware Auto Deploy, which provides the infrastructure for loading the ESXi image directly into the host’s memory. The software image of a stateless ESXi is loaded from the Auto Deploy Server after every boot. In this context, the image with which the host boots is identified as the image profile.

                      An image profile is a collection of vSphere Installation Bundles (VIBs) required for the host to operate and the image profile includes base VIBs from VMware and additional VIBs from partners.

                      On a stateless host, VEM software can be installed or upgraded using either the VUM or CLI.

                      In addition, you should bundle the new or modified VEM module in the image profile from which the stateless host boots. If it is not bundled in the image profile, the VEM module does not persist across reboots of the stateless host.

                      For more information about the VMware Auto Deploy Infrastructure and stateless boot process, see the “Installing ESXi using VMware Auto Deploy” chapter of the vSphere Installation and Setup, vSphere 5.0.0 document.

                      Adding the Cisco Nexus 1000V to an ESXi Image Profile

                      Before You Begin
                      • Install and set up the VMware Auto Deploy Server. See the vSphere Installation and Setup document.
                      • Install the VMware PowerCLI on a Windows platform. This step is required for bundling the VEM module into the image profile. For more information, see the vSphere PowerCLI Installation Guide.
                      • On the same Windows platform, where VMware PowerCLI is installed, do the following:
                        • Download the image profile offline bundle, which is a ZIP file, to a local file path.
                        • Download the VEM offline bundle, which is a ZIP file, to a local file path.

                      Note

                      In the following procedure, the image profile bundle is available as C:\ESXi-5.0.0-depot.zip and the VEM bundle is available as C:\VEM500-20110822140-BG.zip.

                      Procedure
                        Step 1   Start the vSphere PowerCLI application.
                        Step 2   Connect to the vCenter Server. 
                        [vSphere PowerCLI] > Connect-VIServer 192.0.2.1 –User Administrator –Password XXXXX
                        Step 3   Load the image profile offline bundle.
                        Note   

                        Each image profile bundle can include multiple image profiles. 

                        [vSphere PowerCLI] > Add-ESXSoftwareDepot c:\vmware-ESXi-5.0.0-depot.zip
                        Step 4   List the image profiles.

                        Step 10   Export the image profile to a depot file for future use. 
                        [vSphere PowerCLI] > Export-EsxImageProfile –ImageProfile n1kv-Image –FilePath C:\n1kv-Image.zip –ExportToBundle.
                        Step 11   Set up the rule for the host to boot with this image profile.
                        Note   

                        Any of the host parameters, such as the MAC address, IPV4 IP address, or domain name, can be used to associate an image profile with the host. 

                        [vSphere PowerCLI] > New-deployrule -item $img -name rule-test –Pattern “mac=00:50:56:b6:03:c1” 
[vSphere PowerCLI] > Add-DeployRule -DeployRule rule-test
                        Step 12   Display the configured rule to make sure that the correct image profile is associated with the host. 
                        [vSphere PowerCLI] > Get-DeployRuleSet 

Name        : rule-test
PatternList : {mac=00:50:56:b6:03:c1}
ItemList    : {n1kv-Image}
                        Step 13   Reboot the host.

                        The host contacts the Auto-Deploy Server and presents the host boot parameters. The Auto Deploy server checks the rules to find the image profile associated with this host and loads the image to the host’s memory. The host boots from the image.
