About Adding Hosts to Nexus 1000V DVS

Adding hosts to Nexus 1000V DVS is a complex operation. This section describes the scope of the Add Hosts wizard and how to translate your intended usage into proper choices.

Adding a host requires the following :

Specifying a Nexus 1000V DVS and the host that is being added to it.
Using a port profile editor to view the existing port profiles and to create new port profiles in case the existing ones are inadequate for your purpose. For an overview of the Cisco Nexus1000V port profiles, see the http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus1000/sw/5_2_1_s_v_3_1_1/port_profile/config/b_Cisco_N1KV_VMware_Port_Profile_Config_521SV311.html
Selecting one or more physical interfaces of the host to migrate to the virtual switch and attaching the right port profile to each one.
Establishing a VM kernel NIC for Cisco Nexus1000V control traffic.
Optionally migrating previously created virtual kernel NICs (vmknics).
Creating one or more (upto a maximum of four) VM kernel NICs for VXLAN encapsulation. In VXLAN terminology, these VM Kernel NICs serve the role of VTEPs, which are the VXLAN Tunnel End Points.
Optionally migrating some or all of the Virtual Machines that may already be present on the host.

Once you name the virtual account for the deployment and select the specifications from the corresponding drop-down lists, the virtual switch and host specifications get created. Port profiles are an abstraction that stands for a set of port level network attributes. They come in the following two flavors :

Physical port profiles

These contain attributes relevant to the physical interfaces. You can set up a physical port profile to carry multiple VLANs. One of these vlans must be designated as the native VLAN. Traffic on the native VLAN travels on the wire, without 802.1Q encapsulation. A virtual port profile for the purposes of the 'Add Host' wizard can carry traffic on just one VLAN. For any virtual interface, irrespective of whether it is the interface of a VM or a VM Kernel NIC, you can associate a particular virtual port profile only if the VLAN it specifies, has been included in one of the physical port profiles associated with one of the physical interfaces. The VLAN associated with any virtual interface on a host must be carried on one of the physical interfaces of that host.

Physical port profiles also specify if the interfaces that they attach to form a logical bundle and if they do, whether it is a bundle of type '5 tuple hash-based static portchannel' or of type 'MAC Pinning'. For an understanding of what these interface types are, see the http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus1000/sw/5_2_1_s_v_3_1_1/interfaces/config/b_Cisco_N1KV_VMware_Interface_Config_521SV311/b_Cisco_Nexus_1000V_Interface_Configuration_Guide_Release_4_2_1_SV_2_2_1_chapter_0110.html
Virtual port profiles

These contain attributes suitable for VMs or VM Kernel NICs. A specially designated virtual Kernel NIC must be established on each host to exchange management and control signals with the Cisco Nexus1000V Virtual Supervisor Module (VSM). The simplest way is to specify migrating the pre-existing management VM Kernel NIC (usually named vmk0). Alternatively you can create a VM Kernel NIC expressly for this purpose. If you exercise the latter option, we recommend that these specifically created VM Kernel NICs belong to the same VLAN and have IP addresses in the same subnet as the management interface of the VSM module. It is not necessary to ensure this when you are simply choosing to use the management VM Kernel NIC as the control VM Kernel NIC.

You must follow this simple rule for creating VTEP VM Kernel NICs. If the physical interfaces of a host are not in a MAC pinning mode port channel, a single VTEP NIC suffices. If they are in MAC Pinning mode, you can create as many VTEP VM Kernel NIcs as the number of physical interfaces being migrated on that host. Moreover, all VTEP NICs on all hosts in a single virtual switch must be in the same VLAN and the same subnet.

The Cisco VACS Add Host wizard will try to restrict you to legitimate choices. For instance, it will try to detect which VLAN is native on each physical interfaces that you want to migrate. It will also try to discover which VLAN the management VMKernel NIC is on in case you choose to re-use it as the control VM Kernel NIC. However there are times when these automatic discovery attempts can fail. You must ensure correct choices for native VLANs of the physical interfaces as well as the VLAN for the control VM Kernel NIC.

Adding Hosts

After a successful installation of the Cisco VACS license and Cisco Nexus 1000V, you can install Cisco Nexus 1000V Virtual Ethernet Module (VEM) for a VMware ESXserver .

Note

The Help link provides you access to the corresponding online help.
Rollback recovery is not supported for the Add Host operation.
For this release, Cisco VACs allows you to add only one host at a time to the Nexus1000 DVS.
We recommend that you turn on the CDP on the server ports before starting the Add Host wizard.

Before You Begin

Before beginning the Cisco Nexus 1000V VEM software installation, you must know or do the following:

The following are the disk and memory usage for the VEM software on an ESX/ESXi host:
- 6.5 MB of disk space
- Maximum of 4 GB of RAM when all Cisco Nexus 1000V features are activated.

Step 1

From the Cisco UCS Director menu bar, choose Solutions > VACS Container. The Cisco VACS management task icons appear.

Step 2

Click Add Host. The Add Host wizard appears.

Figure 3. Add Host Wizard

Step 3

In the Host Location Specification screen, complete the following fields :

Name	Description
Virtual Account drop-down list	Choose the name of the virtual account.
Datacenter drop-down list	Choose the datacenter where the host is present.
Nexus 1000V Switch drop-down list	Choose a Cisco Nexus 1000V DVS to add the hosts.
Host drop-down list	Choose a standalone host or a host from the cluster in the datacenter, that you want to add to the Nexus1000V DVS.

Step 4

Click Next. The Port Profle Configuration screen appears.

Step 5

In the Port Profle Configuration screen, review the port profiles that can be used by the physical interfaces (PNIC) or the virtual interfaces (VNIC).

The Port Profle Configuration screen lets you view or create port profiles. These port profiles are applied to the physical interfaces that you want to add to the virtual switch or to the virtual interfaces of the VMs. The Port Profile table lists the existing port profiles and displays some suggested port profiles for the selected host. You can modify or delete the suggested port profiles, or add new ones. After you finish managing the port profiles, you are prompted to apply them to the host’s physical interfaces or to the VMs on the host that you want to migrate to the Cisco Nexus 1000V. Any newly created port profiles in this list that are not assigned to any interface—physical or virtual—do not persist on the switch. Before exiting this screen, ensure that suitable port profiles exist for all the physical server ports that you intend to migrate to the Cisco Nexus 1000V. If the UI does not pre populate the Port Profile table with suitable port profiles, you must add them manually.

Note

Only those port profiles that have Exists?=no can be modified. The port profile with Exists?=yes are those that are already available on the VSM and cannot be modified. There could be instances wherein this screen will not display any port profiles.

For Ethernet port profiles, only static port channel and virtual port channel host mode (vPC -HM) is supported.

The list of port profiles is displayed. You can modify or delete the suggested port profiles, or add new port profiles. If you want to add more port profiles, click + and fill in the following details in the Add Entry to Port Profile screen. If you want to modify an existing port profile, then select the appropriate port profile and click the edit (pencil) icon which is located next to + and modify the existing field.

Step 6

In the Add Entry to Port Profile screen, complete the following fields:

Field

Description

Profile Name field

Enter a unique name for the port profile. The valid range is 2 to 32.

Port Profile Specification

VLANs field

Enter a VLAN list as a comma-separated list of numeric IDs and numeric ID ranges. For example, "1,3,5-8,6-9,11,20-30". The valid range is 1 to 3967 and 4048 and 4093.

A port profile with the Physical Interface check box checked, can usually carry multiple VLANs in a list. Port profiles for virtual machines only carry a single VLAN. Attempting to assign a list to a port profile with the Physical Interface check box unchecked results in an error.

Physical Interface check box

Check this check box to indicate that this port profile is intended for use with the physical interfaces of the host. Uncheck the check box to indicate that the port profile is meant for use with one or more virtual interfaces.

By default, this check box is unchecked.

Native VLAN field

If you check the Use for physical interfaces check box, you can enter the Native VLAN ID for this port profile. This field is pre-populated with a value of 1.

Note

The valid range is 1 to 3967 and 4048 and 4093.
Ensure that you provide the correct VLAN for the native VLAN field. If you don't do so, the addition of a host to the Nexus 1000V DVS fails.
This field is displayed if the Physical Interface check box is unchecked. I

Channel Group MacPinning check box

Check this check box to enable port–channel of type Mac–Pinning. If unchecked, all of the interfaces to which this port profile is applied form a static port channel.

Note

By default, the Channel Group MacPinning is disabled.

Click Submit.

Repeat the above steps for physical port-profiles. For virtual machine port-profiles, only the VLAN and Native VLAN fields are displayed. You must choose the appropriate VLAN configuration.

Step 7

Click Next on the Port Profile Configuration screen after you have modified or added the required port profiles. . The Physical NIC Migration Configuration screen appears.

Step 8

In the Physical NIC Migration Configuration screen, you can view all the PNICs present in the host, with a suggested port-profile mapped to it and the migration to be set to true.

Setting the migration flag to a value of true indicates that the corresponding PNIC will be migrated to Cisco Nexus 1000V.

Step 9

To edit the Port-profile mapping, migration status, or the container traffic check for an existing PNIC, select the appropriate PNIC and click the edit (pencil) icon and modify the existing fields.

Attention:

It is necessary that you enable at least one physical NIC to use for container traffic. If you do not enable it, you cannot proceed with the wizard.

The Edit Physical NICs Entry screen appears.

Step 10

(Optional) In the Edit Physical NICs Entry screen, modify the existing fields, and then click Submit.

Name

Description

Select PNIC to Migrate

Name field

This display-only field shows the interface name.

Migration check box

Check the check box to enable the migration of the PNIC to the Cisco Nexus 1000V.

Note

By default, all the PNICs are set to true for that migration. You can uncheck the check box to prevent migrating the PNIC to the Cisco Nexus 1000V.

Port Profile drop-down list

Choose the port profile from the list of available port profiles that are associated to the physical interfaces.

Use for Container Traffic check box

Check this check box to indicate that the port profile mapped to the PNIC is data-capable. A data-capable port profile is applied to those physical interfaces that carry all of the container traffic. This distinguishes such a port profile from one applied to physical interfaces intended only to carry other traffic classes such as vMotion traffic, host management traffic and storage traffic. All traffic classes can also be multiplexed on the same set of interfaces which would then still be designated as data capable.

Attention:

In every host, there must be exactly one physical port profile in use that is marked data capable.

Source vSwitch field

This display-only field shows the virtual switch with which the interface is currently associated.

Repeat this step for the other PNICs that you want to modify.

Click Submit.

Step 11

In the Physical NIC Migration Configuration screen, click Next. The Kernel NIC Migration Specification screen appears.

Step 12

In the Kernel NIC Migration Specification screen, complete the following fields:

Each host in a Cisco Nexus 1000V virtual switch must set up a virtual kernel NIC (VMKNIC) to carry the control protocol between the host software and the VSM. In Cisco Nexus 1000V terminology, this VMKNIC is referred to as the L3 control VMKNIC of the host. This screen enables you to set up and configure the L3 control VMKNIC for the host and also provides you an option to migrate the existing VMKNICs from the vswitch to Nexus1000V DVS.

Name

Description

Migrate Kernel NICs check box

Check the check box to view the list of all available VMKNICs.

By default this check box is checked.

VM Kernel NICS table

Displays the list of all available VMKNICS. You are allowed to edit the VLAN and the VMKNIC usage information. This table is displayed when you check the Migrate Kernel NICs check box.

Note

The VMKNICs whose usage is Management will be used for L3 control communication between the host and the VSM. You can have only 1 VMKNIC which can be management (usually the host management VMKNIC)

An additional VMKNIC can be used for Storage usage. This configures the iSCSI–multipath feature on the Cisco Nexus1000V for that VMKNIC.

Important:

You must ensure that the VLANs mentioned in the table are correct for the VMKNIC and that those VLANs are allowed in the port-profile that was mapped to the physical NIC in the Physical NIC Migration Configuration screen.

Step 13

(Optional) If you want to modify the attributes of an existing VMKNIC, then select the appropriate VMKNIC, and then click the edit (pencil) icon and modify the existing fields.

Step 14

(Optional) In the Edit VM KNICs Entry screen, modify the existing fields, and then click Submit.

Name

Description

Select VM Kernel to Migrate

Name field

This display-only field shows the VM kernel name.

VLAN drop-down list

Choose a VLAN to use with the L3 control VMKNIC. The list contains only those VLANS that were added to the physical port profiles and are mapped to the PNICs in the earlier screens.

Usage drop-downl list

Choose the usage of the VMKNIC – management, storage, or unassigned (blank).

Management usage is automatically added to the management VMKNIC of the host by Cisco VACS. If it is not matching the host management VMKNIC, change the management usage mapping to the right VMKNIC.

If the storage VMKNIC is present, mark the VMKNIC with usage storage. The iSCSI-mulitpath feature of the Cisco Nexus 1000V will be added to this VMKNIC.

If the VMKNICs are not used for management or storage, then leave the usage as unassigned.

Note

You can have only one VMKNIC with management usage and it has to be the ESX host management VMKNIC.

Do not change the VMKNIC usage without verifying the existing VMKNIC configuration and usage on the vswitch.

Click Submit.

Step 15

(Optional) If you want to add new VMKNICs instead of using existing VMKNICs, then uncheck the Migrate Kernel NICs check box and complete the following fields:

Name

Description

VLAN drop-down list

Choose a VLAN to use with the L3 control vmknic.

Note

This option is available if the Migrate Kernel NICs check box is not checked.

IPv4 Address

Enter the IPv4 address for the L3 control VMKNIC.

Note

This option is available if theMigrate Kernel NICs check box is not checked.

IPv4 Subnet Mask

Enter the subnet mask IPv4 address .

Note

This option is available if theMigrate Kernel NICs check box is not checked.

Step 16

Click Next. The VXLAN VTEP Interfaces screen appears.

Step 17

In the VXLAN VTEP Interfaces screen, click + to add entries to the list of VXLAN VTEP interfaces list.

VXLAN operation requires that each host have one or more Virtual Tunnel End Points (VTEPs). These are represented as vmknics. If the host has data-capable physical interfaces configured in a static port channel mode, then a single VTEP suffices. If the host has one or more physical interfaces configured using the Mac Pinning configuration, then the user can accordingly create as many VTEPs as there are physical interfaces in the MAC pinning configuration. Creating fewer VTEPs results in underutilization of the physical bandwidth that is available to the host.

Name	Description
Add Entry to VTEP Interfaces
IPv4 Address field	Enter the IPv4 address of the VXLAN VTEP.
IPv4 Subnet Mask field	Enter the subnet mask IPv4 address .
VLAN drop-down list	Choose a VLAN that will receive and transmit all VXLAN encapsulated frames. The list contains only those VLANS that were added to the physical port profiles and are mapped to the PNICs in the earlier screens.
	Click Submit.

Note

You can create a maximum of four VXLAN VTEP interfaces to add to the list of interfaces. After you add the first interface, you have to enter only the new IPV4 address to create additional interfaces. All other information is shared between the interfaces across all hosts added via Cisco VACS.

If you want to change the VLAN or subnet mask of the VTEPs, then you must select the first VTEP that you added, click the Edit button at the top of the table, and then change the fields. All of the VTEPS in the table will be changed.

Attention:

You must choose a sufficiently large IP subnet as all the VTEPs of all the hosts added to a single Nexus1000V DVS will belong to the same subnet. This cannot be edited in the UI and the add host process will not proceed further if the IP addresses of the provided subnet are completely utilized.

Step 18

Click Next.

Step 19

In the VM Migration Configuration screen, select the VM NIC to migrate and click Next. If you want to edit an entry, click the Pencil icon and complete the following tasks in the Edit VM NICs to Migrate screen:

Field	Description
Select a VM to Migrate
Name field	This display-only field shows the name of virtual machine that is being migrated.
Migration check box	The check box is unchecked by default. Check the check box to migrate the virtual machine to the Cisco Nexus 1000V DVS.
Port Profile drop-down list	Choose the port profile for the virtual machine to migrate. Only the virtual port profiles that were displayed or created in the Port Profile Configuration screen are listed in this drop-down list.
Source vSwitch field	This display-only field shows the virtual switch with which the virtual machine is currently associated.
	Click Submit.

Note

If there are only fresh hosts, this list is empty. This list will be populated with VMs only when a host is previously used and it has VMs that you want to migrate.

Step 20

Click Next.

Step 21

In the Add Host Summary Information screen, verify the details of the host added. If the details are correct, click Submit. Otherwise, click Back to go back to a previous steps and modify the details.

After clicking Submit, a pop-up window appears that shows a service request number that can be used to track the progress of the Workflow, as described in the next step.

Step 22

You can view the progress of adding hosts, by clicking on the Organization > Service Requests. In the Service Request tab, you can view the Workflow Status or Logs to determine the status of the installation and troubleshoot problems.

Note

Re-submission of Add-host is not recommended. If there are errors, navigate to the Add-Host UI and Submit the form again. Note that, the port-profiles suggested in the 2nd screen will now have changed, so choose/edit them appropriately.
If the host addition fails, you can manually remove the partial or an unsuccessful host addition. To manually remove the hosts added, see the Removing the Hosts Manually. For additional troubleshooting tips, see Problems with Adding Hosts.
