• How to make a route between two routers (networks) connected to the same switch?

  Hello guys, how are you?

  In my company, we have 2 internet routers more dsl router of data connected to 1 switch line

  the data row is used to connect the branches of our company together for network problems.

  the router 192.168.2.1 IP data

  internet routers IP 192.168.1.1 - 57.194.97.1

  We have 3 accesspoints wireless taking their internet of 192.168.1.1 oky guy

  what I want to do is when I connect to any wireless network to connect to the data line dsl with router 192.168.2.1

  When I use the ethernet on my pc I have IP addresses 192.168.2.222 for router data line and 192.168.1.222 for internet

  but the wireless is DHCP n that it is connected only to 192.168.1.1, which is the internet router, how can I do 192.168.1.1 192.168.2.1 when I connect

  using the wireless?

  I hope that you understand me ^_^

• Try to change several network adapters on a virtual machine

  Here's what I have to change several virtual machines with an adapter:

  $test5 = import-Csv C:\test5.csv

  {foreach ($vm to $test5)

  $server = $vm.name

  $networkname = $vm.networkname

  Write-host "Changing $server to the new $networkname network.

  Get - VM $server | Get-NetworkAdapter | Together-NetworkAdapter - networkname $networkname - confirm: $false

  # #Start Server

  Write-Host "Made from $server"

  Start-VM $server - confirm: $false

  Write-Host "complete!"

  }

  It looks like a spreadsheet with the name of a column and networkname in the other and sets the adapter accordingly.  It works so much that there is only one network adapter to set... for example if there is a virtual machine with vlan1 for 3 network cards on a virtual machine, it will define all 3 cards to the vlan 1, but if a network card is different from vlan 1 it will fail.  How to fix a vm with multiple NICs?  I tried to separate them by a comma, but he doesn't like it.  Any ideas?

  You can add additional columns in your CSV file.

  Something like that

  Name, NetworkName1, NetworkName2, NetworkName3

  VM1, net1, net2 net3

  VM2, net1, net1 net1

  Then, you can change the code something like this

  $test5 = import-Csv C:\test5.csv

  {foreach ($vm to $test5)

  $server = $vm.name

  Get - VM $server | Get-NetworkAdapter | %{

  if($_.) {Name - eq '1 network card')}

  Together-NetworkAdapter - NetworkAdapter $_ - NetworkName $vm.networkname1 - confirm: $false

  }

  ElseIf ($_.) {Name - eq "Adapter 2")}

  Together-NetworkAdapter - NetworkAdapter $_ - NetworkName $vm.networkname2 - confirm: $false

  }

  ElseIf ($_.) {Name - eq "3 network adapter")}

  Together-NetworkAdapter - NetworkAdapter $_ - NetworkName $vm.networkname3 - confirm: $false

  }

  }

  Write-host "Changing $server to the new $networkname network.

  # #Start Server

  Write-Host "Made from $server"

  Start-VM $server - confirm: $false

  Write-Host "complete!"

  }

• Assign an individual ethernet NETWORK adapter to a virtual machine

  Hi all

  We wish you a new year filled with joy and happiness.

  I just install ESX 4.1.0 and vsphere 4.1.0.

  I have a couple of additional NIC cards available in the ESX Server. I would like to assign to each VM.

  I have configured the virtual switch as "vswitch0" and all additional NIC cards appear on this switch. But I couldn't find a way to permanently assign a NETWORK adapter to a virtual machine specific.

  I have 3 NICs and I intend to have 3 VM.

  Anyone can guide me please.

  Thank you

  Krishna

  An option is to create 3 virtual machine port groups and assign each virtual machine to one of them. In the configuration of the port group, set a NIC to 'Active' and the other two to 'Sleep'. In this way each VM uses a dedicated NETWORK card and - failure - switches to one of the others.

• ESXi 5.5 nic teaming/LAG with trunking does not but it works on ESX 4.0.  Both are on the same switch. What gives?

  I have two hosts (vhost1 = ESX 4.0, vhost2 = 5.5 ESX) both are configured for the Group and both connected to a switch of 1544 Adtran L3 (named sw01).  vhost1 has been in production for several years with the config below and has been solid as a rock.  I'm trying to reproduce the installation of grouping/collage on vhost2 and it does not work when are associated but will work when you are using a single NIC (with or without aggregation).

  To be more specific about what does not work, two virtual servers have "Network server" (vlan 8) defined as a group of ports. Both physical and virtual servers on the same vlan cannot ping or resolve queries arp for virtual machines on vhost2.    Everything that is sent from a different subnet can connect to the virtual machines on each virtual server.

  So the question is this: why not ESX 5.5 works as ESX 4.0 when the configs are also near identical, as I can make them and they are connected to the same switch?

  Thanks for any input you can provide!

  Hello

  Do you share the vmnic for ESXi management and network of the VM?

  Try to follow the steps in this KB: VMware KB: NICs using EtherChannel grouping allows intermittent network connectivity in ESXi

  Trying to team adapters using EtherChannel, network connectivity is disrupted on an ESXi host. This problem occurs because grouping NIC properties will not propagate to the network management portgroup in ESXi.

  When you configure the ESXi host for grouping of NETWORK cards in attributing to the road based on ip hashload balancing, this configuration is not propagated to the portgroup management network.

  Workaround

  Note: to reduce the possibility network loss please change the route based on the hash of IP using this method of balancing load vSwitch

  1. Close all ports in the physical switch team leaving a single port as active.
  2. Change the Route based on ip hash vSwitch and load balancing management Portgroup.
  3. Set up the physical switch port channel.
  4. Activate the physical switch ports.

  Notes: Using this method will avoid a loss of connection when you switch to a port channel. Also make sure that under the properties for vmk portgroup # used for network management you tick the box "Enabled".

• Can I mix vNIC 10 GB and 1 GB on the same switch?

  Small question.  Can I have a vnic 10 GB and a vnic 1 GB on the same switch management network, with the 10 GB set as active and the 1 GB as standby?  I am running a HA cluster on vSphere 5.5u2.

  Yes, you can add a vmnic with different speeds for the same vSwitch without problems (unless you want to use the pipe).

• Switch ports connected with cross cable on the same switch...

  Hi experts,

  Just got a doubt.

  If both a stand-alone switch ports are connected by a crossover cable, how will be the stp of attitude toward this scenario...

  Thank you

  Arun

  Hi arun,

  As we all know the switches use according to criteria of application PLEASE:

  (1) to root the lowest BID

  (2) a low-cost path to the bridge root

  (3) OFFERED the lowest sender

  (4) minimum port priority

  (5) the lowest port id.

  So in your senario until number 4 allvalues will be equal and there will be a match tie. So for port breakage id will be used and the port with the higher port number will be blocked and low port id will be in a State of fwding.

  Example:

  If you've been through e1/1 and e1/2 cable on the same switch then 1/1 b in condition of fwding all-in-1/2 will b in the blocking state.

  HTH,

  Kind regards

  Shri :)

• Network problem between the machines Win XP and Win 7

  I have 2 machines, a desktop and a laptop.  The office is currently running Windows 7 Pro (installed on 2010-01-01) and the laptop is running Win XP Pro.

  The desktop (Win 7) can see the laptop (XP) on the network and can access the shared folders.

  However, the reverse is not true.  The laptop can detect the office as a computer on the network.  I can double click the icon and see the files of office that are shared.  But when I try to access the content of the files, I get a message that says I don't have permissions and contact the system administrator.

  I also have a problem with the shared printer (connected to desktop Win 7).  Before the upgrade both machines can print, after the upgrade, the laptop (Win XP) stopped printing.  I installed the XP drivers for the printer (using the functionality of additional drivers) on Win 7, deleted the printer on the XP computer connection and he still added.  The XP machine was able to find the printer on the network, but when I try to print, I get an arror message saying that "(l'imprimante peut être désactivé, pas branché ou les pilotes ne sont pas installés)."

  I think that the two problems are related, but I can't understand where is the problem.  Print and file sharing is 'on' on both computers, the firewall is configured to allow printing the file and shares, folders are set to 'share', with "everyone" under permissions and both machines have the same network name.

  Any ideas? Am I missing something?  Is it possible to reset all default values so I can set up the network again from scratch?

  Thanks in advance a lot.

  Probably, you have a misconfigured firewall and/or do not have matching accounts/passwords user on both machines.
  Here are the steps of general network troubleshooting. Just cannot apply to your situation, so just take the bits that are. It may seem daunting, but if you follow the steps in the links and suggestions below calmly and consistently, you will have no difficulty to implement your sharing.

  Problems sharing files between computers on a network are usually caused by 1) a misconfigured firewall or a firewall neglected (including a dynamic firewall in a virtual private network); or (2) inadvertently run two firewalls such as the firewall of Windows and a third-party firewall. and/or (3) do not have accounts to the same users and passwords on all computers in the workgroup. (4) tries to create actions where the operating system does not.

  In Windows 7, go to control panel > everything in Control Panel > network and sharing Center. Click on "change the advanced sharing settings. You don't want to use the residential group unless you have all Windows 7 machines. If you do and you want to use the homegroup, see Windows 7 Help & Support. Otherwise, in sharing advanced:

  Discovery of plug in the network
  Open the files and printers sharing
  Turn on the sharing section Public folder sharing
  Plug the password protected sharing

  A. configure the firewall on all machines to allow traffic to local area network (LAN) as being approved. With the Windows Firewall, turning on window file sharing and printer as the above will take care of that for you. If you are not running a third-party firewall or you have an antivirus/security with its own firewall component program, then you're fine.  With a third-party firewall, I usually set up the allocation of LAN with an IP address range. E.g. would be 192.168.1.0 - 192.168.1.254. Obviously you would substitute your correct subnet. Refer to the safety of any third party program or the user forums for how to correctly configure its firewall. Do not run more than one firewall. DON'T STOP FIREWALLS; CONFIGURE THEM CORRECTLY.

  (B) to facilitate the Organization, put all computers in the same workgroup. This is done from the System applet in Control Panel, the computer name tab.

  C. create the counterpart of the user accounts and passwords on all machines. You do not need to be logged into the same account on all machines and assigned to each user account passwords can be different; accounts/passwords just need to exist and to match on all machines. DO NOT NEGLECT TO CREATE PASSWORDS, EVEN IF ONLY OF SIMPLE. If you want a machine to boot directly to the desktop (a particular user account) for convenience, you can do this:

  Start > Search box > type: netplwiz [Enter]
  Click continue (or provide an administrator password) when you are prompted by UAC

  Uncheck "users must enter a user name and password to use this computer". Select a user account to connect automatically by clicking on the account you want to highlight and press OK. Enter the password for this user account (when it exists) when you are prompted. Leave blank if there is no password (null).

  XP - set up Windows to automatically connect (MVP Ramesh) - http://windowsxp.mvps.org/Autologon.htm

  D. Si one or more of the computers on your network are XP Pro or Media Center, turn off Simple file sharing (Folder Options > view tab).

  E. create share as you wish. In Windows 7 I usually share the Desktop of the user and the Public directory.

  F. you have the job of file sharing (and tested by exchanging a file between machines), if you want to share a printer connected locally to one of your computers, share of this machine. Then go to the printer mftr Web site. and download the latest drivers for the correct system. Install them on the target machines. The printer must be collected during the installation procedure. If this isn't the case, install the drivers and then use the Add Printer Wizard. In some cases, printers must be installed as local printers, but it is outside this response.

• network stream between 2 virtual machines in the same vlan and host using DVS

  Hi experts, so 2 virtual machines on the same vlan / subnet and on the same esxi host using VDS need to talk to each other, that they get switched by the VDS internally or they headed north for network switches and come back?

  Welcome to the community - it will stay internal to the ESXi host.

• Disable the network interface on a virtual machine

  Hello all-

  Is there a way to disable the network interface on the network adapter in the virtual machine?  We have a group of applications who want to simulate a network in collaboration with MSCS failure - I don't necessarily agree with the fact that this type of test, but try to determine if this is possible from the functional point of view.

  Our ESX host have networks of virtual machine set up off the coast of 4 port nic mezzanine card, and I don't want to touch the VM network vswitch as any part of this test.

  Thanks for any help you can provide-

  Steve

  Is there a way to disable the network interface on the network adapter in the virtual machine?

  Yes, in the virtual machine settings, for each NIC assigned to the virtual machine you will find a checkbox 'connected '. Unchecking it's like pulling the network cable.

• How to change network name for all virtual machines within the same cluster

  We have recently changed name vswitch to take into account that something significant, in the past vCenter could change the labels of networh for all virtual machines... seems this time help labels are not changed (maybe its got something to do with the update vcenter for 2.5.U3)...

  in any case, someone at - it a powershell script that could find all the virtual machines that are referring to the old label network and then changing again the name... ?

  Enjoy the respponses...

  Thanks in advance

  A few things on this blog could help.

  If you know the names you want to use, you could also just use something like:

  Get-Cluster X | Get-VM | Get-NetworkAdapter | Where { $_.NetworkName -eq "OldNetwork" } | Set-NetworkAdapter -NetworkName "NewNetwork" -confirm:$false
  Get-Cluster X | Get-VM | Get-NetworkAdapter | Where { $_.NetworkName -eq "NewNetwork" } | Set-NetworkAdapter -Connected:$true -confirm:$false
