• 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

  

• VCenter shows a network for a virtual machine that is not associated with any host

  I have a win2k3 VM who at one point had a network assigned to him called "MONITORING".  This network is configured is no longer in the ESXi (5.5) environment.  The virtual machine is connected to a network called "PRD-SURVEILLANCE" which is correct.  It's not really cause a problem, but I can't find a way to get rid of the object of MONITORING network.

  In VCenter MONITORING networks has a VM of 1 meter, the number of hosts of 0.  I also see it in the VM - dialog box, change the settings, but there is no option to remove it.  Profile Image to the virtual machine is version 10 so I can't use the old Client of VI to try to remove it.  I have checked each host and do not see this listed network object.

  I tried to restart the VM, it migration between hosts, changing its network of SURVEILLANCE of PRD to another network and vice versa and close - remove NIC and add a new card network.  MONITORING legacy network still appears in the config.

  For the virtual machine's .vmx file shows that the correct network: ethernet0.networkName = 'RDP-ANALYSIS '.

  Any suggestions on how I can remove the artifact of MONITORING network?

  The virtual machine has a preview that was created at the time where the MONITORING network was still affected?

• Need to Partition network each insertion of new data?

  Hello

  I would just ask, if I have a network that is partitioned with the help of SDO_NET. LOGICAL_POWERLAW_PARTITION and I added more data in my table of knots and links after the partitioning of the network, I need to run SDO_NET. Once again LOGICAL_POWERLAW_PARTITION?

  Thank you

  Hello

  When the network topology changes you must divide the new network to reflect the change.

  You will need to re - build the blobs of partition when you partition the network.

  I hope that helps!

• VCenter 2.5 Networking Tips

  I am currently in VCenter Server 2.5 with 3 guests. I am now noticing that the VMKernal (ISCSI) even if the switch has 2 network cards, it seems that actually use an adapter. I configured storage Round Robin paths to test. I wonder if anyone other suggestions for evening on the use of the network card.

  my whole army currently have the following network installation

  Service console on the production with 1 adapter network

  Network of the VM with 3 cards on the production network

  VMKernel and service (2nd) Console with 2 adapters on a single physical switch for ISCSI

  Any helpful info would be greatly appreciated

  I will probably add my ISCSI target has 3 NICs connected to the physical ISCSI network switch and that VCenter sees 3-way in each data store

  Hello

  Do you provide different paths of the 2 separate IP network for iSCSI?

  I'm not sure about this, but I had to set up xen with NetApp iSCSI storage server, and it seemed that best practices have been to put two ethernet cards in the host to two separate IP networks (and possibly two separate switching devices).

  NetApp controllers have been configured in the same way, each port on each controller on two different networks (and each controller connected to a different switch port).

  The idea is to be able to ping two controllers remote iSCSI through two separate paths of material.

  Now, I suppose that if you have only one controller on your storage device, you won't we able to use different networks, but in this case, I don't see how the TCP/IP stack will be able to balance the traffic on two different cards that are on the same network. As far as I KNOW, the TCP IP stack chooses an arbitrary to a designated network card and will stick to this topic.

  Let me know what you find, I always try to understand this possibility, but this config worked fine with my client

• vCenter 5.1 - network problem between the host computers

  vCenter 5.1

  (2) the hosts running esxi 5.1

  I have VM in a single dvSwitch and dvPortGroup on two hosts - VM total 5.

  This is where it gets weird:

  -all VM on host1 can ping/browse all VM on host2

  -VM on host2 can ping/browse all * EXCEPT ONE * VM on host1.

  -All virtual machines can ping Bridge and beyond

  Otherwise said - VM1 on host 1 may VM3 and VM2 host2 ping, but VM3 and VM2 cannot ping VM1.

  No firewall or anything like that in the guests, because VM4 on host1 * CAN * ping VM1.

  Looks like an arp or vNetwork question.

  Thoughts, known problems?

  Found!

  I got 2 ports not tagged in the VLAN for switch problems.

  While everything went on-site in the configurations, hard links to the switch are the root cause.

  Thanks for your comments - he has led me on the way to finally discover the question.

  Cisco PVLANS (Private VLANS) are not supported at the moment on ESX 3.5 vswitchs. Would be a nice feature, but we will have to wait and see

• Cannot add host ESXi 5.5 to vCenter for a routed network - cannot communicate with the specified host

  I was wondering if anyone has come across this problem before, who could give advice how to fix them:

  Host of pre-production UCS ESXi migration of a Production vCenter on another network (routing in place)

  Can ping both directions successfully - from vCenter Prod to the host of the pre-production

  no firewall between the two.

  902 port is open on the host

  Host connects to the pre-production vCenter on the subnet even fine

  VCenter production can add different hosts on the same network end

  Even with the various guests of ESXi UCS.

  ESXi host was completely disconnected and removed from vCenter inherited before attempting to add. No dvswitch physical or virtual.

  Then try and add, enter the user name and password and get cannot communicate with the specified host.

  Thank you

  The solution to this. Used ESX host 5.5 3B (3248547) update that disables SSLv3. (Ref: VMware ESXi 5.5 updated Notes version 3B) one of the consequences of this is that older versions of vCenter (such as trying to move the host) can not add/connect host.

  Enable SSLv3 to spend (port 443) on the resolved host (virtuallyPeculiar: connection A ESXi 5.5 U3b host to vCenter with a lower Version A.)

  Note: should not enable SSLv3 to Port 902.

• ESXi 4.1 Update 1 and material update 4 to 7 cards of network breaks vCenter.

  I installed ESXi 4.1 update 01 on 2 servers.  Then I updated the hardware version of all servers in version 4 to 7.  Now the vCenter has no network adapters!  Research in the Windows Device Manager indicates Intel E1000 adapters with a yellow exclaimation point.  Try updating the drivers doesn't produce a message that says that the drivers are up to date.  All other Windows servers work correctly with their network cards, just the Windows 2008 R2 64-bit vCenter server is not able to connect to a network.

  Hope someone has an answer.  Called VMware support, but they will call back within 8 hours.

  You can check 'NIC hidden' and then delete them if they exist as described in article 1179 KB.

• new to vmware, vsphere and networking vswitch

  Hi all

  I am new to virtualization, but decided to try it since my company is going full on ESXI5.5.  That is why I hope that some kind gurus here can point me in the right direction regarding some doubts I have... and do not forgive me if I ask ridiculous questions...

  ==========

  So far, I know that VMs, through their vNIC connect to vSwitch which is in turn connected to the physical machine or the host ESXI (vmnic) network card. The vmnic is then connected to a real L2/L3 switch.

  [VM Vnic] <>- [vswitch] <>- [vmnic] <>- [physical switch]

  However, what I don't understand is how the vmnic actually works to spread the traffic "inward" to the vswitch? I can't really come up with one question to explain my doubt, but below are the doubts that I asked myself->

  • How is he able to assign the IP off the internal virtual machines?
  • When an outer package of the physical switch is being sent to the vmnic how he spend in-house for internal virtual computers?
  • How even knows designated IP belong to a virtual machine inside and "inward" to happen to the vswitch?
  • Is the vmnic using address IP or MAC to decide if it means putting the package inside the switch?
  • When an arp request for a virtual machine IP is send from the outside, the vmnic will reply with its mac address?
  • When an arp request is sent from an internal virtual machine, the vmnic keep track of the mac address of the virtual machine so that next time, when he saw a response to this MAC, he knows inside 'before' the vSwitch
  • What is this work something like a 'bridge' mode fill the vswitch internal to the external physical switch? Is there a table of addresses belonging to the vmnic mac?
  • Whenever the IP of the virtual computer is assigned, the IP address will be "bind" to the vmnic?
  • How register us all IP or Mac addresses (if any) that are associated with a vmnic?

  Or rather simply, I wonder how the physical network adapter on the host (esxi), knows that he must transfer a frame "inward" to the vswitch? is there a link OF the virtual machine to the interface? or nic was a table of addresses mac or something... (but the mac address table guess belong to vswitch?)

  Thank you.

  Kind regards

  Hello

  Welcome to the community!

  I would like to start with a doc. I recommend you to read our VMware Virtual Networking Concepts guide that I hope will help you to better understand the basic details of the virtual in VMware switch, even if it's a bit old.

  On your last question, however:

  > Or rather simply put, I wonder how the physical network adapter on the host (esxi), knows that he must transfer a frame "inward" to the vswitch? is there an IP link from the virtual machine to the interface? or nic was a table of addresses mac or something... (but the mac address table supposed to belong to vswitch?)

  The vminc (i.e. the physical card) on the ESXi host is not that there is a virtual switch behind it. It transfers the packets to the driver and then the top layer software it management. There is no magic to this topic. In some cases, there are a few added techniques (for example netqueue), but the basis remains the same. Vmnic (i.e. the physical NETWORK adapter card) does not keep the information of MAC address of the virtual machine on virtual machines, but does the vSwitch. But even the vSwitch does not retain details of the IP address.

  A virtual switch, as such, doesn't have the same kind of as a physical switch mac address table. If a virtual machine under tension then the vSwitch stores the virtual port <->combination MAC address number and keeps it like that (so far it's really no different a physical switch). A big difference is that, well that the vSwitch does not learn the MAC addresses of the external network. If there is a picture of outside with the MAC address of unicast for which there is no port isn't linked then the packet gets dropped. And if the virtual machine sends traffic to another MAC that does not exist in the virtual switch and then it will be sent out via the uplink (s) (if it exists).

  The MAC address of the vmnic does not play here (unless one of the vmkernel interface pulls his MAC to an adapter of uplink).

  I hope this helps. Let me know if you still have any questions.

• Advantages and disadvantages of the use of the same network card to the network management and production (all my virtual machines) VLAN?

  Hello

  I have an ESXi. The management network and the virtual machines vlan through the same network adapter.

  What the disadvantages are to do?

  Can you help me please?

  Thank you in advance,

  Kind regards

  Garish

  Well well, in this case. This is a perfect case of SPOF, try to reach NIC teaming to avoid this.

  At least two cards physical network is necessary in your hardware ESXi host to do.

  Download an official guide of VMware Networking from the following URL, it has got everything you need and much more.

• Network for NFS

  Hello

  I have infrastructure as follows;

  2 welcome each containing 6 1Gig speed NIC each.

  A NAS storage with 4 NIC

  Two L2 Switches (managed HP).

  Planning to run it by the best recommendations and requirements, so that there should not be a SPOF any level.

  So keeping this in mind, we have designed to use ports on each server as follows:

  2 for the NFS storage, 2 for Production management and 2 others for vMotion on each server.

  A cable from each port configured for respective roles goes uplink switch1 and switch2, so if a switch goes down we still have the other switch support.

  Separated VLAN is configured by the switch to different types of traffic.

  My question as below;

  Should I team two ports on each vSS.If so that what should be the parameters for NETWORK adapters for the production, storage, and vMotion network grouping (keeping in mind cables going to switch uplink separated).

  Should I keep adapter in active-standby or active-active mode.

  I didn't think any specific settings to link pass that one cable by a single port is to go there and I don't have the choice of the channel of the ether or LACP.

  In addition, vmware license is essential and having therefore no possibility to use dynamic switches.

  Consider using 5.5.0.

  Also do you propose to use frames as well in the present.

  Kind regards

  Hello

  I suggest always you put management and vMotion on the same set of natachasery management and workloads. It makes no difference where they are subnet a perspective.  I also suggest to read the following:

  • The great debate VSwitch (old writings but still VERY there, let not the age fool you on this one)
  • VMware Virtual networking concepts
  • Networking for administrators of virtualization

  Who should you get.

  natachasery have no IP address in a vSphere environment, they act as a link between a physical and virtual switch. According to the way which you the trunk your VLAN Trunk ends pSwitch (external switch tagging) or the virtual switch (switch virtual tagging). Most people master their VLAN to the virtual switch.

  You want something like the following:

  pSwitch <->pNIC0 <->[ <->Portgroup vSwitch0] <->management (subnet1)

  pSwitch <->pNIC1 <->[ <->Portgroup vSwitch0] <->vMotion (subnet2)

  When switching between pNIC0 and pNIC1 management and vMotion end up on the same bear but when normally run that they remain separated. It is the recommended method. In this case you would master the VLAN to the vSwitch. I know some people who just do not use VLANs, but who use only separate subnets and it works as well.

  pSwitch <->pNIC2/pNIC3 <-> <->Portgroup vSwitch1 (s) <->of workloads (subnet1)

  If you use VLANs (except for vMotion) you're trunking to vSwitch1 (virtual switch tagging). If subnet1 is on the same vSwitch and the trunk is correct via pSwitch ports so he can talk to management on vSwitch0 effortlessly. Switches know how to route traffic to VLAN.

  pSwitch <->pNIC4/pNIC5 <->vSwitch2 <->Portgroup <->NFS (subnet3)

  Here we link pNIC4 and pNIC5 together or use them as a pair of failover for NFS on its own subnet / VLAN itself. This VLAN can end the pSwitch if you wish or terminate once again to the vSwitch.

  In this configuration you have 3 VLAN and 3 subnets (subnets use by VLAN are also recommended)... for example:

  VLAN100-> subnet1-> workload management

  VLAN200->-> vMOtion subnet2

  VLAN300->-> NFS subnet3

  Let the pSwitches any 'movement' of traffic for each VLAN. You need only a routing device if you want TO cross borders VLAN and there is absolutely no need to do it in this configuration.

• Unable to assign the IP of network profiles.

  Hello

  I want to activate the user select network based on the network available, chosen in PG when you set a reservation. I use XML to list outside these exchanges but facing problems with it. I use vCAC 5.2 with vSphere 5.5

  The model is configured with a network adapter, keeping in mind that what ever network selected by the user would add to the provisioned VM.

  1. I am able to get the Port Group reflected in vcenter under the network section, but the setting of the virtual machine does not added adapter list. I could see Mac address associated to the Portgroup and allocated IP network profile, but I do not see these values in the VM.

  2 - I custom configured VM from vCAC and added additional NIC with different portgroup who also has associated the different subnet network profile. This time I could see port group reflected in vCenter under network and also the adapter is also added to the VM, but still could not see IP address other APIPA address then. However a single IP address again responsibility network profiles that does not matter where in the VM.

  have I missed something? is there an agent that must be installed on a virtual computer to enable this feature (just a wild guess! )

  Help, please!

  BR,

  MG

  Yes this actually solved the problem, but it's still strange that we need to care about customization in vCenter and reference should be placed in the strategic plan, how construction profile Important in this scenario?

  However, custom, property of "CloneSpec" is not required to mention under properties if you use the field 'customization Specs"of Blueprint.

  This requires no installation of the Agent. It is agentless.

  Thank you

• Requirements of ports for vCenter Server 5.1 - SysLog Collector

  Hi all

  Has anyone installed a SysLog collector?

  My book of vmware by Lowe mentions little on the ports for it.

  During the installation of the server, he gave me a list of ports.

  I accepted all the flaws, except that I changed the ports http to 81 and 8081 because IIS is installed (vmware docs say to use one port other than 80, if IIS is already installed)

  Now, during the installation of the SysLog collector it asks which http port I use.

  The vmware docs nothing mentioned on the syslog http port is my book. The vmware for TCP docs show that.

  ESXi Syslog Collector

  8001

  TCP

  ESXi

  vCenter Server

  Network syslog server

  Just use port 81 as the http port I have set up for vcenter server? The web interface won't connect through this port? There will be a conflict?

  I used netstat and port 82 is not used. Should I use?

  The other settings works ok?

  There is no firewall involved; vCenter server and the VMs system will reside on the same site

  Thanks in advance

  port 81, that is according to the third screenshot! 8081 is for Tomcat!

• I fired my off-grid vCenter Server

  Hello everyone,

  I have a 5.1 vcenter server running as a virtual machine (win2k8R2). We have all the virtual machines on distributed switch. I had to upgrade the vnic on vcenter server vm to VMXNET3 E1000. I made a mistake by deleting the existing network card before you add the new network adapter. Now I'm not able to make the VM vcenter on the network. The NETWORK card I added is disconnected and does not see any portgroup who select us in the menu to the bottom to choose the network for the VM.

  I think it's because VDS is managed by vcenter himself and vcenter being out of the network, it does not show the exchanges on VDS that I can connect to.

  All I can think is that I'll have to add a new network adapter on the host and create a VSS and vcenter vm it first add and transfer it to service VDS. But I have no network card now. It is in production

  Suggestions how to add vcenter to VDS?

  Thanks - AG

  Add a NIC temporarily and created a VSS with VM network. Low-pressure vCenter to VSS and then in the properties of the VM, replaced by NIC vDS.

  Thank you all.
