• read com ports with command-line through labview?

  I'm trying to find a way to get a specific com port through the command via the command exec system prompt in labview. Is it possible to get the list of com port connections just like one you see in Device Manager where he will give the list the name of the device connected to a certain com port? I want to be able to automatically find the port com for a specific device.

  because it is a virtual com port that gets set up and I tried the vi to find resources VISA and it did not work. However, funny enough, just after I submitted this post, I found the solution to my problem. If you use exec system and type this command in the standard input:

  WMIC path Win32_SerialPort

  This will bring up a list of all com ports connected and very fast too. From there I can analyze the information I want and widdle down to the com of the desired usb device port.

  Maybe this can help someone on the road.

• NIC team Active standby failover - how to see which physical adapter is actively used at a specific time by a VM or VMKernel port

  Hello, simple question.

  I have a vSwitch with two portgroup VMKernel. The switch is connected with two network adapters. The failover policy is set at the level of Portgroup. PG1 has active nic1 and nic 2 in standby mode. PG2 nic 1 standby and active NIC 2. I want to know via cli or gui, command which nic is actually used for a portgroup at a specific time. Is this possible?

  Thank you!

• Explanations on lawless VMKernel & port management pour network configuration

  Hello

  When my money of VCenter configurations, I understand a little better connections in the VSwitches ports VMKernels and Managements of Port.

  Is this the same chosen?

  Thanks in advance

  Under ESX on was 3 types of ports/network:

  -Console of Service-> dedicated to the administration of the ESX

  -VMKernel: Used pour storage NAS and iSCSI-> allows you to Allocate an IP to the ESX

  -VM Network: Ream pour create the network of virtual machines

  Under ESXi, there is more service Console, everything is now in the vmkernel. 'Network management' is the name given to the vmkernel port created during installation of the ESXi and on which to active the ESXi management

• 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.

• 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}}

• 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.

• explanation of VMkernel ports

  Someone can explain to me why vmkernel ports have ip addresses and what are they?

  I know it's stupid, but if someone could explain me as if I wasa kid of 5 years... would be nice.

  Thank you.

• 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.

• Nexus 1000v and vmkernel ports

  What is the best practice to put on the nexus 1000v vmkernel ports? Is it a good idea to put all the ports of vms and vmkernel on nexus 1000v? switch or dvs or some vmkernel as management ports must be on a standard?  If something happens to the 1000v, all management and vms will be unreachable.

  any tips?

  Yep, that's correct. Port system profiles don't require any communication between the MEC and VSM.

• VMKernel port group

  Here is the configuration of the network of one of our hosts ESX 4.1:

  (1) the virtual computer network

  (2) Service with 1 IP console

  (3) VMKernel with 1 IP for vMotion and iSCSI, called as VMKernel_iSCI

  I can see there are 4 NICs attached to this host.

  Now, I just know, that same using iSCSI and vMotion VMKernel is not a good practice.

  question 1

  So I would like to know how is the mapping of the ESX host's network. Is this;

  1 NETWORK card = 1 VM Network

  1 NETWORK card = 1 Service Console

  1 card NETWORK = 1 which is currently used for iscsi and vmotion VMKernel port group

  In a standard switch, there are 2 network cards configured.

  2nd question

  I want to delete 1 port VMKernal vmotion (VMKernel_iSCI) and create a dedicated for vmotion.

  I know that I have will require another IP address, but what of NIC, it will be;

  1 NETWORK card = VMKernel_iSCSI

  1 NETWORK card = VMKernel_vMotion

  Please explain.

  Thank you

  Mihir

  From a pure technical point of view, it will work, as long as your network is configured properly (i.e. taking advantage of VLAN and the separate subnets on management, vMotion and iSCSI). However, I am worried about the bandwidth and quarrels with such a configuration.

  BTW. except if you've already seen it, I would recommend that you take a look at http://www.vmware.com/files/pdf/virtual_networking_concepts.pdf

• 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
  #Add gateway IP address
  $netMgr = Get-View (Get-VMHost $hostname6 | Get-View).ConfigManager.NetworkSystem $iproute = New-Object VMware.Vim.HostIpRouteConfig $iproute.defaultGateway = "10.33.1.3"$iproute.GatewayDevice = "vmk0"$netMgr.UpdateIpRouteConfig($iproute)
  

• 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.

• Access NAS storage of ESXi Server using VMKernel Port?

  Hello

  I would like to know the best procedure to connect to the NAS storage of ESXi host 5. I am able to connect to the NAS storage according to the screenshots listed in the link below.

  http://www.tintri.com/blog/2011/11/connecting-vSphere-to-NFS-the-easy-way/

  But, I saw different configurations in the past where port dedicated VMkernel is assigned to NAS and all storage goes into network 10 G. I try to do the same and created a VMkernel for NAS port. But I don't think that traffic is going over there as it is not used at all.

  I gave the IP address of the ESXi server on the NAS box to get access. I couldn't give address IP VMkernel sideways NAS. How can I make use of this IP VMKernel dedicated NFS storage?

  I want to implement the best way to pass NAS 10 G network traffic. In addition, How can I test if storage traffic crosses VMkernel port?

  Suggestions needed.

  Virtualinfra is right that you must use a different subnet for NFS traffic. You masked the IP range, so I don't see what you use, but make sure that the vmkernel and storage using a single subnet, not the management subnet. If you get an error, your use of a subnet that goes out the default gateway of the management port, or that you are using the same subnet.

  I wrote a few articles on the use of NFS with vSphere: http://wahlnetwork.com/2012/04/19/nfs-on-vsphere-a-few-misconceptions/

  Also, make sure that the vmnic can route traffic on that subnet, as in the case of the use of VLANs.
