Issue of V-Switch virtual network, possible configuration of VLAN

• A bet with the network team - configure the VLANs on Teddy does not work against Cisco?

  Hello

  We have a great place of Esx and I have a bet with one of the network Admins.

  I configured a vSwitch to work with 1 bear. On this vSwitch I configured 1 vlan with a Vlan ID 100

  I told the guy from the network to set up the bear side here and he said he has set up 'Access' and not trunk as normally I ask because it's only 1 Vlan.

  I said ok and we tried and nothing works, when I configured the Vlan 0 in the Esx, it started working.

  Of course we cannot leave it like that and need to Config the Vlan on the Esx.

  I told them that once I configured the Vlan on my side there is nothing to do there, and they need to do the thing here.

  they say the same thing.

  Who is right? It is something they need to configure side here if she's 'access' and not 'trunk '?

  or is it something at my side?

• Not available in the configuration of the adapter VMNet8 virtual network

  Hi all

  I have HAD the following config:

  Virtual Server 2 on a machine with a physical NIC XP

  Two comments machines two Ent W2K3 running.

  IP address 192.168.1.1 and 2.1 default gateway of 192.168.1.5

  Both machines network cards configured to use VMNET8. VMNET 8 configured through the virtual network with IP 192.168.1.5 Editor

  The virtual card configured VMNET8 with 192.168.1.5 address in the host network configuration and the default gateway set as 192.168.0.254, that is the address of the gateway for my network home.

  With this config, I have had my two virtual on the same network and "Native" computers to the internet via my home network.

  Problem now is that somehow my journey becomes stripped on the host. The NIC VMNET8 achieved somehow a metric is lower than the physical host adapter. No problem when accessing the net from virtual methods, but when you try to access the net from the host machine, it attempts to route the internet traffic on the virtual interface on VMNET8 and of course fails.

  In addition, the possibility to connect the virtual machines to VMNET8 is not an option in NIC on each virtual machine settings more. I only have NAT, connected by a bridge and host-only.

  I spent some time on the issue without success so I uninstalled VMware and removed two virtual machines. After you have reinstalled, I am always presented with the same two questions.

  Does anyone have an suggestions?

  Kind regards

  Hamish.

  Welcome to the forums!

  I would say to keep the values by default as long as you have a good reason to change.

  Configure:

  I guess 192.168.1.0/24 is your address for VMnet8 network!

  The adapter VMnet8 host to:

  no gateway 192.168.1.1 by default, it is not necessary here.

  Comments:

  Either DHCP (served by the DHCP of VMware Server) or fixed IP 192.168.1. < starting="" with="" 10=""> , DNS, default gateway: 192.168.1.2
  If you use the VMware DHCP server control if 192.168.1.0/24 is configured as network VMnet8 address.

  Do not connect to the vNIC to VMnet8, choose 'NAT', which is VMnet8.

• VIRTUAL network interface routed, is this possible?

  I have a 3560 which hangs a 6509. The next SVI s direct on the 3560:

  192.168.181.1(VLAN 192.168.180.1 (VLAN 180), 181), 192.168.182.1 (VLAN 182), 192.168.183.1 (VLAN 183), 192.168.184.1 (VLAN 183).

  I have the following routed interfaces between the 6509 (192.168.0.17/32 and the 3506 (192.168.0.18/32).)  Currently, I use a gateway of last resort to get the traffic off of the switch and a static route to send traffic to these IVS.

  I have a few VLANS that I use for vSpere and traffic of ESXI (239 (vMotion), 243 (Fault Tolerance), (250, iSCSIStorage), 254, ESXi), 255 network management).

  Is it possible to send these VIRTUAL networks through the routed interface?

  I have a few guests of ESXi requiring 254, 239 and 243 for vSphere features.

  Short answer is with the equipment you have not you cannot.

  What you can do is-

  (1) create a new vlan purely for the link between the switches and create an IVR for this vlan on each switch.

  The IPS for the Lass will be the IP addresses that you currently have on routed ports.

  (2) the link is a link to trunk and leave the new vlan and a VLAN that you want to extend for example. between the switches.

  The important thing here is to allow only on the trunk link the new vlan, and the VLAN that you extend.

  (3) the VLAN that you not extend ie. VLAN 180, 181 etc are not allowed on the trunk link and therefore will be always sent between switches across the new vlan because the Lass for this vlan have the IPs had initially allocated you to the ports of L3.

• With the help of virtual network switches

  I use VMware Player 3.

  After you create a virtual machine, how can I associate a network interface to a given virtual network switch?

  I see no possibility to associate it with a particular switch, say VMnet4.

  Can I edit the .vmx file manually?

  Concerning

  Marius

  Yes, you will need to manually change.

  Where (n)"in what follows is the target number.

  ethernet(n).connectionType = "custom"
  ethernet(n).vnet = "vmnet(n)"
  

  For example...

  ethernet0.connectionType = "custom"
  ethernet0.vnet = "vmnet2"
  

• Multiple virtual networks on a configuration

  I want to know if it is possible to have more than one virtual network on a configuration and virtual machines on each network to communicate with each other.  I have already setup with two networks, but theres no way VMS ping on the other network, because theres no device to route traffic between them.

  I bet there are others having this problem and maybe found a workaround.

  Thank you

  Windows Server or linux with active routing is exactly the thing.

  LM will create its own router of fencing of physical networks, but there is nothing in the product to interconnect two networks of arbitrariness in the config.

• Network/DNS/DHCP issues with testlab - virtual network Editor is killing me!

  Hey all - a little new with workstation and have been messing around trying to get this to work for so long, I want to just set up my lab already but can't find the catch here.

  So, here is what I tried to do:

  Have a hand of Windows Server 2008 R2 (Controller/DHCP/DNS/Active Directory domain / IIS) addresses/leases DHCP of an internal network (which means, I want some Windows 7 Ultimate customers to assign IPs to the DC and NOT of VMWare offers integrated DHCP). I want clients to be able to use only one NIC (preferably) and both authenticate to AD and connect to the Internet (so I think I'll pass on DNS to resolve external domains?). I'm having a pretty hard time trying to understand what...

  My physical network is an active router Linksys with DHCP, so them to assign an IP address to the PC that I'm looking for this laboratory-perhaps it is a problem as well and must also be configured or have my VMNet reflecting?

  I tried to use NAT, a bridge connection, etc... and even then, when I got my DC with an active internet connection, how would I configure my clients (Win7 devices) to join the network even on my domain controller is? I tried some configurations in these forums as well, but none seems to for what I'm trying (which seems very simple!). Can anyone offer some advice? I am not opposed to the fresh start. Thanks for taking a peek.

  Here is an example of configuration when all the virtual machines are configured for NAT.

  Virtual network Editor:

  DHCP disabled for NAT

  For an example, I assume that the NAT subnet in 192.168. 100. x. You can change this if you wish.

  DC:

  IP address: 192.168.100.10

  Subnet mask: 255.255.255.0

  Gateway: 192.168.100.2

  DNS server: 127.0.0.1

  Configuration of the DHCP server:

  Range: 192.168.100.150... 200

  Subnet: 255.255.255.0

  Gateway: 192.168.100.2

  DNS server: 192.168.100.10

  The DNS server configuration:

  DNS forwarding to: 192.168.100.2 (for other than the own domain URLS)

  Other servers or systems with static IP settings:

  IP address: 192.168.100.11... 149

  Subnet mask: 255.255.255.0

  Gateway: 192.168.100.2

  DNS server: 192.168.100.10

  Customer:

  Networking will be set to automatic.

  In this way, the domain controller will be the only DHCP and DNS server, but each virtual computer will be able to access directly to the Internet. And because the domain controller is the primary DNS, your ad cannot function properly.

• DC virtual in VMWare Server virtual network configuration

  I'll put up a virtual AD network on a virtual server installation.  The host machine is supposed to be portable (i.e. the LAN IP will change, and it may be offline from time to time).  I'm trying to set up the first machine on my network, the virtual domain controller.  I don't know what to specify for the default gateway.

  Currently, on the domain controller, IPv4 is configured as follows:

  1 = bridged network adapter

  IP address: 192.168.131.1

  Subnet mask: 255.255.255.0

  Default gateway: (empty)

  Preferred DNS: 127.0.0.1

  Alternate DNS: 64.71.255.198

  Should I leave it like that, or specify one virtual network cards as the default gateway?

  Without a default gateway, you will not be able to route to the DNS server that you specified: auxiliary DNS: 64.71.255.198

  If you think you have all the traffic in your MS local virtual (hosting IE everything than ob this host and always keeping local traffic), then no DG not required, but I suspect you'll want to make the web etc as you go along, if you need a DG to be routable

• Issue of duplicate virtual networks

  In ESX server, I can create many virtual networks that are on the same subnet on the same host? I have a 'service' that requires four virtual servers, work together and each group of four servers is assigned to a specific customer. At the moment I create unique and re-IPing networks servers for each new deployment for every new customer and I wish I could just build a complete environment that works and then them themselves in groups as needed for new customers.

  It's hard to describe, but here's a basic example of what I'm trying to do:

  Server 1 - 192.168.1.1 - connected to the virtual network 2

  Server 2 - 192.168.1.2 - connected to the virtual network 2

  Server 3 - 192.168.1.3 - connected to the virtual network 2

  Server 4 - 192.168.1.4 - connected to the virtual network 2, packed to the physical NETWORK (network 1) card with a unique IP address

  Server 1 - 192.168.1.1 - connected to the virtual network 3

  Server 2 - 192.168.1.2 - connected to the virtual network 3

  Server 3 - 192.168.1.3 - connected to the virtual network 3

  Server 4 - 192.168.1.4 - connected to the virtual network 3, packed to the physical NETWORK (network 1) card with a unique IP address

  Server 1 - 192.168.1.1 - connected to the virtual network 4

  Server 2 - 192.168.1.2 - connected to the virtual network 4

  Server 3 - 192.168.1.3 - connected to the virtual network 4

  Server 4 - 192.168.1.4 - connected to the virtual network 4, filled to the physical NETWORK (network 1) card with a unique IP address

  Nope ESXi will not worry. I did it for the test on a smaller scale environments. I guess your IP Managment is on a separate network.

• The Port of the switch to ESX host configuration

  I have a switch that connects to a physical server used in

  virtualization.  This means that virtual machines with IP addresses on

  several subnets will send layer 2 frames to this switch.

  However, in an attempt to reduce the number of network adapters on the server

  It is.   If there is only one card NETWORK in this physics

  Server connected to a physical switch port - it is possible to

  with a port on the handful of physical switch frames that come

  all virtual machines running on the physical server - when these VMs have IPs

  different subnets?  Or each separate subnet property intellectual logic requires a

  switch port separated to manage its images and its own on physical NETWORK card

  the server used for virtualization?

  Thanks for your comments

  Yes, you need to configure the physical switch port as a trunk and then configure the VLAN tagging on your Exchange Configuration-> Networking.

• Configuration of VLAN Switch Distributed

  Hello

  This a configuration problem and I'm not really sure how to set it up.

  I created a distributed switch, and ESXi1 and ESXi2 are members. I created a comeback portgroup named A_01 and is a member of the VLAN 101.

  I created a virtual XP1 machine in ESXi1 located in A_01 and I created a VM XP2 on ESXi2 located in A_01.

  They do not communicate.

  I have a switch between them and the uplink for the distributed switch of ESXi1 is connected to port1 and ESXi2 uplink is connected to port2

  I have 'tag' port1 and port2 in vlan 101.

  They do not communicate.

  I have both change the network of the VM XP1 and XP2 VM a portgroup with no VLAN they communicate.

  What I am doing wrong.

  Thank you!

  "I have both change the XP1 XP2 VM VM network in a portgroup with no VLAN they communicate."

  --> its because your physical switch is configured as port access . Marking is done at the level of the physical switch. This is the expected behavior.

  If you want to tag the VLAN level vSwitch, then you must put the physical switch as a trunk port and VLAN 101.

• Isolate virtual networks in vCenter in a network environment

  Hello

  I am trying to isolate a group of vlan was in vCenter in a network environment. I currently have 10 assigned resource pools with different vlan id (350-360). This network environment includes several Cisco 3750 switches configured for connections. 2 VLAN separate were created on the switches to prevent access to two separate places in our building (VLAN 50 and 60).

  The objective here is to limit access to 5 pools of resources to a single office. That means that 5 resource pools (including 100 vm) can only be accessed from a desktop and not the other. The Cisco switch in this office has been configured for vlan traffic through 60 only, but is still not isolate traffic for vlan 50.

  My question: are there additional changes that must be made in the Network Configuration file in vCenter or what I need to make additional configuration changes to my Cisco 3750 switches?

  Any help/advice would be appreciated!

  It's my rating based on p16 and vSphere Networking Guide 5.1 p12. I think about it every now and then. Assuming you are using VST (Virtual Switch Tagging) config, you must ensure that

  1 MV in 5 of the pools you want isolated is mapped to the correct port groups (corresponding to the vlan 50 and 60)

  2 master the correct uplink port on vSS/vDS and physical switch. An easy way is located to 4095, but for security reasons I am generally hosting only VLANs in use.

  3. of physical switch you trunk between edge and core and allow some VLAN specific (e.g. the vlan 50 or 60) on a different port on the switch to edge to hang on your office.

  Hope this helps

  

• Virtual network cards only 100mbs - how to speed up?

  I have a 1 GB physical NETWORK card on my Windows 7 64 bit host. However, virtual network that are installed by 9 workstation cards show that they run at only 100 mbs. Is it possible to run all of the 1 GB instead of 100mbs? I can't find where that is controlled and network cards virtual is not a speed setting that I can find. I wish I had all of the Go go all the way through the virtual hosts (all Windows versions).

  You can change which virtualized NIC is presented to the guest.  Edit the .vmx of the guest and add/edit the following line configuration file:

  If you want an emulated Intel adapter (I think this Signals as a 1 GB link speed):

  ethernet0.virtualDev = "e1000".

  ... Or if you want emulated vmxnet3 adapter (I think this Signals as a 10 GB link speed):

  ethernet0.virtualDev = "vmxnet3.

• Establishment of a virtual network

  Hi all

  Sorry if this question is asked a million times, but as a beginner to ESXi, I'm having some trouble to configure my virtual network. The pointers in the right direction or links to the guides of initiation would be accepted with gratitude.

  Basically, at the moment, I have Win 2 K 8 R2 x 64 and Win 7 x 64 VMs put in place on my server ESXi. The 2 k 8 is a domain on my existing external domain controller. It is also a DHCP and DNS server (I'm going to RRAS later). It has 2 vNIC. The first card (wan) receives an ip address on my broadband router and is therefore very well (I'll deal with public IP addresses later). The second is the interface lan / vlan and is configured with a static IP, 192.168.20.5, which is the address of the dns server and the subnet ip (192.168.20.x) served by DHCP. Ideally, I would like to connect to a physical NETWORK card for the internal network physical, but also a virtual internal network that vms in the same domain can connect to.

  The vm Win7 has a vNIC and does not have an address at the present time. It is configured on VM2, as is the internal vNIC to the domain controller.

  At a later date, I also intend to add a second domain separate and DC with the same configuration (we run two businesses from the same site). There may be any connection between the two. The physical aspect is pretty straighforward. It would simply be a matter of physical extra network adapters and duplicate the configuration for the first area?

  I hope this makes sense.

  Thanks in advance.

  Graeme

  The second network has no network management...

  Network management is used to manage host ESXi itself and has nothing to do with the Virtual Machine networks, so there is no need to install a network of management on each vSwitch.

  ... and I don't have internet on the virtual machine windows 7.

  How could you, without uplink. It is basically the same as for a physical network. If a PC is connected to a switch, and there is no connection to the Internet (for example, a router), you will have the chance to work online.

  It will appear and I could binds to Network 2 VM when it is connected so that the server can serve both physical customers?

  Yes, it should work.

  I need bridging the connections in some way to allow the customer to win 7 access internet connection of the VM network 1.

  What is the purpose of separate areas if you want now fill the networks? What you can do is use a firewall (for example, pfSense), configure a separate vSwitch for each domain (without uplinks) and configure the firewall to connect to each vSwitch 'domain' as well as with the uplink to allow Internet traffic to the different areas but block direct traffic between them.

• The virtual network card speed

  When I installed first of all ESXi5, I got 100 MB switches.  I replaced all the switches in my GB rack server and all the virtual machines and no VMs shows that they are connected to 1 GB.  I downloaded a free lan speed tool to see exactly how quickly my lan speed was and I noticed something strange.  The speed test on my VM server not approached speeds GB but when I test all my virtual machines I get only 100 MB speeds.

  I noticed in the configuration of the client vSphere tab its only showing 100 full duplex MB.  I've selected the vmnic0 and chose to edit the properties and change the configuration to 1000 full duplex mb speed.  This change has dropped all my virtual machines offline and when I checked on the physical server, I noticed the NIC has no light activity.  I scrambled to understand how to fix it and finally had to use a different port on the NETWORK adapter on the physical server to deliver my virtual machines on the network.  I always show 100bm on vmnic1 speed and always make me 100 MB speeds on the lan test that I run.

  This suggests two qustions for me:

  1. why my first nic stop working when I changed the speed in vSphere and how to operate again?

  2. How can I get my mV GB speeds.

  Thanks in advance for the help!

  Well, there's your problem

  Perhaps your switch port is not configured correctly or you have some faulty wiring or a faulty NETWORK card? Go to the configuration of your network host and click the icon of the legend to the right of vmnic1. This will show you the CDP information and will tell you the interface to check.

  I also see that you are on an old patch level, I highly recommend getting on the latest version, because a NUMA scheduling patch included in this compilation which makes a big difference in performance. This is unrelated to your current number, but thought I would mention it anyway.

  You can patch in the other uplinks to see what they are negotiating to?
