• 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.

• 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

• 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.

• EqualLogic group member network configuration error: "management interface should not be on the san subnet.

  Hello

  We currently have new EqualLogic 6100 device with this network configuration:

  Director of the IP - 192.168.0.2 (VLAN1).

  Member network config:
  eth0 - 192.168.0.3 (VLAN1)
  eth1 - 10.10.10.3 (VLAN2)
  eth2 - 10.10.10.4 (VLAN2)
  eth3 - 10.10.10.5 (VLAN2)
  ETH4 - empty

  I would attribute 192.168.0.4 to eth4, but received the error: "management interface should not be on the san subnet.

  I am sure that all interfaces eth has access to the VLAN1 and VLAN2, mean error indicates that eth4 should not access VLAN2 and only access the VLAN1 on the switch?

  Or eth0 should also have access to the VLAN2 only to reconfigure eth0 and eth4?

  Thank you

  > The group eating IP should be in iscsi VLANS?

  Yes!

  Note: If configure you an EQL it will ask an iSCSI port because nothing is more necessary to bring it up. The doest previous EQLs have a dedicated Mgmt Port and later, you can convert the last ethX as a MGMT port. This is the reason why configure you ISCSI at the beginning. (Think of a mixed group of newer and older models, and you get a picture)

  OK... once again it is the one and only member of the Group and there is making the production host connected to the right?

  The change of IP address, to a 3rd. subnet for temporary use.

  -Do not touch eth0-3 and the IP address of the group now

  -Configure the MGMT port and IP address management in the tempr group. Subnet. Use the Config-> Adv. Group-> network MGMT. You can change the MGMT Port of the Member, and the address IP of MGMT

  -For the registration of the configuration, you will lose access. You must place your admin PC in the templ. subnet so

  -Connect to the GroupMgr with temp again. INTELLECTUAL PROPERTY

  -Now you can change the IP address of group 10.10.10..x

  -Now you can change eth0 10.10.10.2

  -At the end, you can change the address IP of the Group MANAGEMENT, as well as the MGMT Port to 192.168.0.x

  -Change the IP address of your admin PC rear

  A failover, you should consider to hang a serial cable the active controller of the EQL. Use 9600,8,1, N with your favorite terminal program (putty.exe on windows). All the steps, you can perform from the command line.

  If this group and the only member not in production, but you can reset the config and restart from the beginning.

  Kind regards

• 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.

• 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.

• Why vmkernel port for iscsi and vmotion services?

  Hello

  Just a quick question.

  I was trying to understand - why we need to have a vmkernel port when we want to use features such as vmotion or iscsi.

  Why not use them with a console port service or a port of vm management traffic.

  No particular reason.

  Thank you

  Yes. You're not really all that traffic produced by DRS and vMotion actions in your production (maybe time critical).

• Why my system tray showing a new icon and the message "Windows manages this network adapter. Click here to use ProSet/Wireless' when I have a NetGear adapter

  Help!  I'm not a computer guru.

  Today I noticed a new icon in my system tray and when I place my curson on it, I get the message: 'Windows manages the wireless adapter.  Click here to use ProSet/Wireless. "(I have not clicked on the icon so I don't know what would happen if I did.)   I recently downloaded Explorer 8 from the Microsoft site, but except that I have not changed anything with my computer.  I have the NetGear wireless software on my computer, so I was surprised to see ProSet/Wireless.  Also, the ProSet/Wireless will now appear in "programs".  Is it possible that someone is hacking my computer wireless and succeeded in putting the ProSet software? On this subject, or is it something that is connected with Internet Explorer 8?  Either way, I'm running Windows XP and have Norton 360 protection.

  Thanks in advance for your comments.

  What computer brand and model do you have?

  What model Netgear wireless network card?

  It is highly unlikely that anyone who has maliciously installed Intel Pro/Set on your computer (especially considering that he is even not manages your network card).  Also, it is not related to IE 8.  If I had to guess, I assume you have Windows Update configured to install updates "optional equipment" as well as "Critical" updates.  If you do, change this setting.

  Open the Device Manager (start > run > devmgmt.msc > OK), expand the "Network adapters" section by clicking on the +.  What devices are listed under network adapters?

• Active wireless network has no profile in manage wireless networks

  When I go on manage wireless networks, Windows does not display my active network.  When I try manually create a profile for this one and enter all relevant data, it says "access denied."  How to get access?

  XP, Windows is automatically connected to the network at startup upward.  Now, I have to manually type in the Code of the key every time until it will connect.  Is it possible to configure Windows 7 to store the key Code and auto connect to the network at startup?

  In order to get that control as much as possible as quickly as possible, I downloaded and installed the key registry GrantAdminFullControl that allows any folder right click and select full control of the grant Admin for this folder.  In addition, display hidden files in Folder Options so I could arrange, name and categorize folders to the Start Menu for all users.  I right-click on each folder and subfolder on computer to gain so much control that Windows would allow.  Also, disabled UAC temporarily trying to solve the above problem.

  Still no "access denied." I think that if I could manually add a profile for my network, I could find an option allowing Windows to remember my key Code so that when I start the computer, it has auto login and connect wirelessly without the need to enter manually each time code key.

  The people of router tried for more than an hour to solve the problem.  Says the problem is on the side Microsoft, and I entirely agree.  There is a stroke of luck in Windows 7 prevention auto connect.  No problem with XP.

  Hello

  It seems that if the wireless profile is not saved on your computer. Without the wireless recording profile, it can not connect without providing you the key each time.

  So that it can remember without autoconnecting security key, follow these steps:
  -Connect to the network, and select Connect automatically.
  -Open the center network and sharing (via Control Panel).
  -Click on manage wireless networks.
  -Find the profile to the network, double-click it.
  -Uncheck connect automatically when this network is in range, and then click OK.

  Now, you should find that it will remember the security key

  To activate the automatic connection to a certain will make WiFi network the following.

  1. click on start
  2. click on Control Panel
  3. click on network and Internet
  4. click on network and sharing Center
  5 next to view your active networks click on connect or disconnect.
  6. do a right-click the unwanted network and select Properties.
  7. on the connection of the new window tab check "connect automatically".

  See if you can auto connect the network wanted in the next boot.
