VMKernel port group

• How is it that I can ping between ESXi vmkernel interfaces with the sizes of package exceeding the value set in my passage upstream and one located in my vmkernel port group itself?

  
  I have a 10 GB dell powerconnect 8024f the switch and the firmware is OLD, but the port config shows maximum frame size = 9000 to all cable ports

  2 guests ESXi 5.5 wired, build 1331820, put each host computer network is managed by a single port dual qlogic 8150 ANC

  When I connect to my windows VM to check my new 10 GB connectivity (it is configured for jumbo mtu = 9000 frames) and ping-l 8190 against ESXi vmkernel interface that was MTU of 1500, I get an answer without any packet loss... How can it be if the port is configured for only 1500 MTU?  I thought that the two vmkernel port group and vswitch properties must have 9000 mtu defined, it appears that the vswitch properties override the port group properties.

  But I know I must be missing something, a few important concepts, somewhere, because when I connect to ESXi via ssh I can ping devices with values greater than 8190 and not just windows virtual machines that reside on the same host where the ping uses the internal bus, but I am referring to the connections of the host of other ESXi on the switch management.

  In summary - how the VMkernel does ping and response to pings of bigger sizes greater than the value of the switch upstream?   and why do ping with large packets get answers when the vmkernel port group is always set at 1500, is this a bug or is this feature obsolete?   I remember specifically in ESXi5 that I had to configure the vmkernel port group and the vswitch for this property to work.

  Unless you specify "Don ' t fragment" (-f for Windows) you will be able to use any size package successfully.

  For ESXi, take a look at Troubleshooting ESXi Jumbo Frames.

• Add the default gateway for the VMKernel port group

  Hello

  I use this script to create a VMkernel port group, but the last part of the gateway address of updates to script for all groups of VMKernel ports. How can I change the script so it adds the passage for the 55-CHI-VMKernel port group only. Thank you.

  $hostname6 = "host1".
  $pg = New-VirtualPortGroup-55-CHI-VMKernel - VirtualSwitch "vSwitch1' name - VLanId 55

  New-VMHostNetworkAdapter - VMHost $hostname6 - $pg PortGroup - VirtualSwitch "vSwitch1' - '10.33.1.77' IP - subnet"255.255.255.0"- ManagementTrafficEnabled $true mask

  IP address of the gateway #Add
  $netMgr = get-View (Get-VMHost $hostname6 |) Get - View).ConfigManager.NetworkSystem
  $iproute = new-Object VMware.Vim.HostIpRouteConfig
  $iproute.defaultGateway = "10.33.1.3".
  $netMgr.UpdateIpRouteConfig ($iproute)

  Have you tried it like that?

  $hostname6 = 'host1' $pg = New-VirtualPortGroup -Name 55 - CHI-VMKernel -VirtualSwitch "vSwitch1" -VLanId 55
  New-VMHostNetworkAdapter -VMHost $hostname6 -PortGroup $pg -VirtualSwitch "vSwitch1" -IP "10.33.1.77" -SubnetMask "255.255.255.0" -ManagementTrafficEnabled $true

• Put virtual machines inside the VMkernel port group

  Hello

  Network for administrators of VMware SIAS layout:

  "You can not put VMs within that group of port because it is made especially for a VMkernel port."

  However, I use ESXi 5.5 and is able to put normal interface of VM inside the vmk port group. (I only created 1 vmk port group so all virtual machines in the same group with the vmkernel interface)

  May I know if this is a new feature, or something is wrong?

  Thank you!

  This may be possible with distributed switches not with standard switches.

• Distributed port group

  Hi guys,.

  Is it interesting / reason to be distributed without an adapter vmkernel port group?

  I guess that you are referring to a vmnic, the physical network card? If so, the answer is "rarely". The virtual machines in this group of ports cannot talk about what anyone outside the host on which they are located.

  If you are talking about vmkernel from the host interface, the reason why you would have a dvPortgroup without that one would be a VM guest liaison.

• iSCSI Initiator Port Group error

  Problem adding in the vmk second to an existing iSCSI vSwitch.  Original config was 2 vmks - all worked successfully.  1 vmk has been removed to solve network problems.

  Re-created the 2nd vmk, but when going down one of the cards the unused category as soon as active network OK is selected the message "this vmkernel port group contains a NETWORK card.

  which is related to an iSCSI initiator.  Change its settings could disrupt the connection to the iSCSI data store"is displayed.  The response options are Yes or no.  A screenshot is attached.

  vCenter is version 5.0 U1b.  The host is ESXi5.0 U2 and mode of maintenance with none of the guests.  The host on the local disk not stop SAN.  I can safely click Yes, then go back and

  move the vmnic or is there a better way to fix this problem.  Thank you.

  Thanks for sharing the information. Please try below steps:

  Step 1. Remove links in the existing port and reboot the host.

  Step 2. Change the port iSCSI and vmnic preferred value to active group and move the second unused NETWORK card.

  Step 3. Change group 2-port iSCSI and vmnic preferred value in the active State and move the other card unused NETWORK.

  Step 4. Add vmk1 and vmk2 under links in the port iScsi initiator network configuration.

  I hope steps above will help to solve the problem. If you encounter the error even if you please let me know.

• Definition of VLAN ID on vmkernel ports on dVS - Nexus 1000

  I noticed when adding vmkernel ports to a host on the dVS I'm not presented with an option to enter a VLAN ID. Is it because the VLANS is defined at the level of the port on the Nexus Group? Is there a need for me to create these ports on a vSwitch first to set the VLAN and then migrate them to the dVS?

  Thank you

  JD

  The VLAN ID is controlled by the port-profile on the VSMs 1000v. You don't have to specify it.

• VMKernel port done NFS use - management?

  Documentation VMware - Networking ESXi 5.0 vSphere vCenter Server 5.0:

  "The VMkernel TCP/IP stack handles vMotion iSCSI and NFS in the following way."

  If you watch the VMkernel configuration, you can configure a port group for:

  binding of vMotion, FT, lumbering, management and iSCSI ports

  By the process of elimination NFS will use the virtual card for management traffic?

  Right,

  These boxes are available for VMware knows what vmkernal interfaces to use for the management and who to use for vMotion ounces. Your storage protocol that you select is outside the realm of what vsphere manages directly; they haven't needed to put a checkbox in there for iSCSI, NFS, FCoE etc since storage protocols are, in general, managed separately.

  Ideally, you should configure your interface vmkernal on your Standard vSwitch or vDistrubuted switch with network details you have specified for the subnet / VLAN that you chose for NFS [skip the check boxes]. The final State, all your NFS traffic will then flow through the physical network links that are configured for your traffic NFS on your SvS/vDS.

  Without knowing the details of your files and their abilities network/host/server configurations, Setup and best practices may vary.

• VMkernel Port Configuration using Powershell.

  Hello

  I was playing in my test environment with the creation of the virtual switches and powerCLI port groups.

  I created a port group VMkernel using the following command line

  Get-vmhost $vmhost.

  new-vmhostnetworkadapter - portgroup VMkernel - virtualswitch (get-vmhost $vmhost------)

  Get - virtualswitch - name "vSwitch1") - 192.168.1.16 - netmask 255.255.255.0 - VmotionEnabled ip: $true

  My question is how can I set the powerCLI VMkernel default gateway?

  I ran the command above on two hosts configured identically using a startup script. On hosts, I get an error message (sorry forgot it exactly) who said something along the lines of:

  Hot migration not enabled for this host, use the following command to active: game-VMHostAdvancedConfiguration-name "Migrate.Enabled" - value 1

  When I watched the Group of ports, vMotion was checked so don't know why this line was necessary. Is this something that I have to run on all hosts?

  Kind regards

  Roger.

  To set the VMKernel default gateway, you use the UpdateIpRouteConfig method.

  Something like that

  $netMgr = Get-View (Get-VMHost  | Get-View).ConfigManager.NetworkSystem
  
  $iproute = New-Object VMware.Vim.HostIpRouteConfig
  $iproute.defaultGateway = ""
  
  $netMgr.UpdateIpRouteConfig($iproute)
  

  I don't know why you're going to the message about the missing advanced configuration.

• Question about the migration to a new vswitch NFS port group

  We currently have our group of NFS port on the vSwitch that has all our VLAN and I'd like to bring out a vSwitch isolated dedicated network cards that will handle only NFS communnication.

  I have two network cards additional that I configured on an another vSwitch.  My question is can I remove the port from a vSwitch group and add it to this new and expect it to work?  This unmount and mount the NFS volume for me?  It will be just a quick blip?  What is a larger company?  I ask because I'm trying to figure if I need power off all the virtual machines that are on NFS before moving the port group.

  Is there another method that I should follow to do what I'm doing?

  Thank you

  t

  You'll need plan a failure.  You will need to create a new portgroup vmkernel, since you can't really "moving" a portgroup.  In addition, since you must create a vmkernel portgroup, it cannot be on the same subnet as the existing vmkernel portgroup.  You can have two on the same subnet, no matter how vSwitch' are you have.  Also, I'm not 100% sure the NFS, when you go back, to be assigned a new ID and be recognized as a new data store and force you to re-register your vm.  It's pretty easy to do, but it may be necessary.

  It seems that "get-nicteamingpolicy" comandlet cannot take dv types as input, but I don't know if.

• Get the number of VMkernel Ports on a vDS

  I've searched and just can not find the code snippet to read the number of Ports VMkernel on distributed switch.

  Anyone got an excerpt?

  The following PowerCLI command will give you a list of the number of VMKernel ports for all of your distributed switches:

  Get-VDSwitch | Select-Object - property name,

  @{Name = "Number of VMKernel ports"; Expression = {($_ |)} Get-VMHostNetworkAdapter | Where-Object {$_.} {DeviceName as "vmk *"} | Measure - Object). County}}

• Get the VLAN of a port group

  What is the fastest way PowerCLI, when knowing the name of a virtual machine and that it is on a standard switch, I can find the number of VLAN that the port group it uses is labelled for?

  Try ' Get - VM $VM_Name | Get-VirtualPortGroup | SELECT name, VLanId.

• Port group

  Hello world

  I'm new to vmware, I have a standard switch and,.

  I have to add a vlan. I have 4 esxi hosts in a cluster.

  I have connected to the vsphere client. I clicked on one of the host (say host1) configuration - networking - add network-connection type machine virtual vswitch1 (which is my standard switch).

  Under the port group properties, I gave VLANID-90.

  It of over or do I need to change more.

  But I don't see what vlan under host 2, 3 and 4.

  Hello

  I'm trying to understand: you try to configure the computer virtual portgroup host1 and see a new portgroup to host 2-3-4?

  Adding a vlan in virtual switch means add a machine virtual portgroup, and these steps must be made to achieve this:

  1. Add vlan physical switch (and the junction ports that are connected to the host)

  2.1 if you have a distributed vSwitch, simply add a portgroup distributed with the id vlan correct (the configuration is split at the host that are connected to this virtual switch)

  2.2 If you have a Standard switch you must create a group of ports of std in vSwitch for each host that is to be connected (this is your case)

  2.3 If you have a standard switch and you want to do this in a single "action", you must use a powershell script

  Hope this might be helpful...

• How the Virtual Machine port group communication?

  How the Virtual Machine port group communication?

  Port group is virtual aggregation of ports on vSwitch. A vSwitch can have multiple Port groups which separate the different network traffic. Port groups communicate with vSwitch, and we have physical network maps on vSwitch which establish communication with the external network. We can configure security, NIC teaming, traffic shapping nework political and at the level of the port groups. Once the port group is created, we can assign to vNIC

  How to establish communication?

  Public network > Switch L3 Core > ESXi physical adapter > vSwitch > groups > virtual NIC > Virtual Machine

  Virtual machine connect to the physical map using vNIC coming on Port groups. This is how it works.
