• ESX vSwitch router Question

  I have a scenario that I need help with

  I have 4 HOST ESX servers in site A and 2 HOST ESX servers in site B

  Site B has a virtual machine that replicates data to a virtual machine to a physical server in site A to site B

  At site B, I need to create 2 networks - ESX

  vSwitch 1 - accepts traffic from site A

  vSwitch 2 - is on an isolated network

  At any time I have to be able to move a virtual machine to vSwitch2 vSwitch1 and it works without being able to communicate with site a.

  is this possible? Thanks in advance for your help

  I guess that the VM being replicated for is in an engine out of State.  If you turn it on, he ate Site B with the vNIC connected to vSwitch 2 you should be fine.  vSwitches cannot communicate directly with each other.  However, if you have a computer virtual connected to two vSwitches with two network adapters, it is possible that traffic can pass through the virtual machine between networks.

  This is basically what made the Site Recovery Manager.  He manages the replication from Site A to Site B and allows to test the failover of the virtual machine on Site B powered to an internal network (to avoid conflicts).  Looks like you make software replication based, whereas the SRM focuses on the SAN replication.

• Nested 5.5 ESXi in Workstation 10 Networking question

  Hi all

  I have an instance of VMware workstation 10 running on an HP z600 with guest OS in RHEL 6u3 where I am trying to accommodate a nested instance of ESXi 5.5 for a lab environment.  I have no problem with the guest OS (Windows or Linux) network using deck vmnic on workstation instance.  I have set the ESXi Server also uses a vmnic bridge.  I can connect to the end ESX Server from any workstation on my network with vSphere, but I can't connect to all nested ESX Server virtual machine hosting.  I tried Linux and Windows virtual machines with the same result.  Virtual machines do not seem to be a problem to get my (interesting) DHCP Server IPv4 configuration.  From the virtual machine, I cannot ping the default router.  Ping indicates the destination is unreachable.  I ping the IP of management on the ESX Server from any workstation on my network, but not VM.  Network mgt ESX and vmnetwork are on the same vmnic.  Very simple configuration.  Any thoughts on where to start?

• How analizar trafico una VM Red?

  Hola nuevo.

  Estamos inmersos en una VM as ayer review is red desconexiones quejo. Hemos pensado en analizar el trafico red este equipo (tcpdump, network monitor, etc.), pero no estamos seguros of como hacerlo como interpretar los datos posteriormente.

  Is posible leer el trafico Québec entered al Virtual Switch (snifando for example the tarjeta fisica del ESX conectada al vSwitch) y luego interpretar a what VM will dirigido cada datagrama? Grabaciones cada trama viene encapsulada the information of the target VM? Is posible luego verlo analizando el trafico capturado in the tarjeta del host?

  Gracias!

  Hola

  (1) traffic between VM conectadas a UN mismo vSwitch interno, no sale has the tarjeta fisica (aqui una advantage... he puesto that the transfer of information are mucho mas rapida). Traffic between VM conectadas a diferent o different ESX vSwitches if Quebec goes has the tarjeta del ESX-> estabais lo correcto en física

  (2) para poder snifar tarjeta fisica you can:

  (A) Configurar el directly ESX en el snifeo: instalando el sniffeo in el esx software y activando el modo promiscuo the tarjeta than dedicate snifar-> yo lo descartaria por environment (al menos para mi)

  (B) Hacer a mirror switch del fisico del puerto y con monitorizar a fisico como servidor good comment: Aquí tienes as search information that tiene como origin/destino ip o the MAC of the virtual machine that you want to studying. El trafico to ve perfectly el Québec will las a VM.

• aggregation of links to the switch

  Hello

  I have a question about the next thing. Let's say you have a switch connected to the physical ESX host (or 2 for redundancy - does not matter in this case), with 2 x 1 Gbit vmnic (vmnic0, vmnic1). Now, as vswitch LB default strategy is used, it puts VMS on different vmnic automatically, and you can use the links in 2 GB of a host (of course a link to a vm etc..) But if you have conencted router switch with 1Gbit uplink, and you would like to increase link 1Gbit (router switch - & gt;) to 2 GB, so what is required on the switch (with the exception of the second Gbit active connecting to the router - blue link)? Must be configured as portchannel? And if so, then does this change require a reconfiguration side host ESX (vSwitch)?

  Thanks in advance for advice.

• Configuration of the switch...

  Hi guys

  I'm including a basic network (grouping of NIC design) using two network adapters for all communication on some ESX 3.5

  my questions are:

  1 I kept any configuration especial on the physical predisposees as trunk? especially for vmni4 and vmni5?

  2. What is the NIC Teaming on ESX because I want the two active network cards: Load-balancing, failover network detection

  Please let me know what should I have in here

  

  Thank you very much

  Not exactly.  Aggregation of links work properly, make sure you use hash of intellectual property on the ESX vSwitch/portgroup config and src-dst-ip on your switch.  Without it, no 'load balancing' occurs.

• Small question of network

  Hello:

  I have fast network question and I was wondering if someone can help me...

  If I have virtual machines on the same group of ports configured with IP addresses on the same subnet, this means that traffic between virtual machines never leave ESX (vSwitch) box?  If the traffic (between VMs on the same group of post) never leaves the vSwitch, is there a way to block traffic between virtual machines? What is advised here?

  I just want all traffic go by my gateway even between VMs on the same port group... Is this possible?

  Thank you

  qwert

  Virtual machines on the same subnet on the same ESX Server in the same portgroup will never hit the physical network.

  You can force your virtual machines do not ' see ' each other using PVLANs, but you would need vsphere enterprise plus (and distributed its vswitch) to do. But even in this case, since you're still on layer2, VMs will NEVER see each other.

  The only way for your configuration to work, is to put each VM in one VLAN, then deliver them with a physical router.

• Best practice of pointing the finger a new vCenter LM?

  What is the best way to point a different vCenter Lab Manager 4? Our Lab Manager is running in our laboratory vC and we would like it to run in our vC Prod.

  What gets moved or show first? Do I have to move the hosts and then point LM for the new vCenter? Or should I point to the new VirtualCenter and then hover over the hosts?

  Thanks in advance.

  I think that the process that I follow is this.  I'm assuming that LM 4.x.

  Preparation:

  1. Check that your new version of LM and vCenter are compatible.

  2. Plan a for about 2 to 4 hours maintenance window and notify users.

  3. Credentials document ESX root like
     you will need these.  You vCenter LM admin credentials as well.

  4. Document LM physical network to host ESX vSwitch connections.  You will need to manually reconnect those.

  5. Document LM dedicated vCenter configuration of Resource Pool that you will need to recreate and reconnect these.

  6. Organization of document mappings to Resource Pool that you will need to manually reconnect these institutions.

  Performance:

  1. Disable all user accounts or cutting access so no one can connect to LM.

  2. Perform a test deploy it to a known good Configuration and a model - it's your control test.

  3. UN-deploy configurations and virtual machines inside LM.  This must be cancelled all managed LM VMs in vCenter.  Double check to compensate for any orphans well safe and clean.

  4. Disable and remove all LM Resource Pools.

  5. Disable and remove all of LM ESX hosts.

  6. You can use this opportunity to carry out any maintenance or updates on your ESX host, or not.  Sometimes less variable are better.

  7. Hover over your ESX hosts to the new instance of vCenter.  Constitute a required cluster or Resource Pools there.

  8. Configure LM to the new instance of vCenter.

  9. Fix LM of new objects of Pool of resources on the new instance of vCenter.  This could be a host, Cluster, or a real vCenter Resource Pool.

  10. Previous step should prepare all your LM managed ESX hosts, assuming you have entered the right credentials.  Check this.

  11. Manually reconnect your physical network of LM to vSwitch ESX host connections.

  12. Manually reconfigure your LM organization to the Resource Pool mappings.

  13. At this stage, your organization LM Datastore and media couplings must be reconnected, check.

  14. Perform a test to deploy on the good known Configuration and the model used in step 2 - it should work.

  15. Reactivate the accounts of users and/or access.

  16. Email clear at all.

  17. Beer.

• Can I use VMware vSphere CLI to perform a post on esxi 3.5 and 4.0?

  Currently, we use a bash script (mainly vimsh and esxcfg-* command) to set up post on our server ESX (vSwitch, service), update, etc..  I found that it is not a RCLI for vSphere 4.0?  a RCLI be rename to just CLI?

  Secondly, what tools or version would work for ESXi3.5 and 4.0?  Do not write code twice

  And finally, is there any limitation on the CLI or RCLI that it cannot be done locally by esxcfg-# or the VI client

• Enabling NetFlow on Virtual Switch

  I followed the steps of http://www.vmware.com/pdf/vi3_35_25_netflow.pdf, to

  activate the Netlfow on the virtual switches.

  To collect this information, I use the Netflow Analyzer 7 (NFA7).

  The NFA7 began to collect traffic information. But I did not

  know which interface is that, because the names of the interfaces are generic Ifindex1-ifindex6.

  I know not why I see 6 interfaces. I already configure the SNMP protocol

  Community in the NFA7 with these settings NFA7 usually recognize the name of

  for the router and switching devices and interfaces. I have the default MIB

  for SNMP.

  Someone has this installation works?

  Best account.

  Hello

  It is a well known problem with the exporter of Netflow 3.5. The problem lies in the design of ESX vSwitches who do not have true/static virtual port identifiers. The exporter so use the portIDs of the ports concerned, but unfortunately these values cannot be easily mapped to the specific user to the virtual port.

  This is the main reason that the functionality is more experimental - we has not found a way to design it at the level of standards of VMware due to limitations of the Protocol.

  I'd be happy to take any feedback on how to improve it.

• Lab Manager V3 and a second NETWORK card

  Hello everyone. I have a question I hope you can help me with. In Lab Manager V2.5, we were having a problem with fencing. Our fencing required 5 IPs and our customer wants about 100 fences. As we seek to do not use more than 2 C all classes of IP addresses, we hoped an alternative solution.

  Our current idea is to try to use the second NETWORK card on a separate internal switch. This option would use the internal IP for 4 IP addresses and an external IP address. Although this plan seems feasible in theory, the V2.5 Lab Manager did not work to achieve this end. Thus, we are now experiencing V3. Does anyone know if this plan of attack is feasible? If so, what measures are necessary to achieve this goal? The second NETWORK card will be detected automatically by the Lab Manager, or is there a configuration I do not see any there to achieve?

  In short, I need to know if a second NETWORK adapter is feasible with V3 before submitting a request for a second switch. Please let me know if anyone has any info on this subject. Thank you kindly.

  LM 3.0 allows to use up to 4 network LM by VM Interfaces.  A Network Interface is the combination of the virtual NETWORK card and a physical interface LM LM 3.0, or virtual network.  Networking has been considerably strengthened LM 2.5 days.  Instead of a comprehensive physical network, you can have several (limit)? Physical networks that map to vSwitches in your vCenter/ESX host environment.  The Act of creating a physical network of LM 3.0 creates a group of ports on the vSwitch that you you mapped physical network LM.  Each physical network can accommodate up to worth (1024) 4 c of static IP addresses.  If you want that your different physical networks LM using different physical network interface cards on the ESX host, map to different vCenter/ESX vSwitches.

  Fencing is also managed a little more dynamically without the limitations in number of closed configs that were in previous versions.  All virtual machines in a fenced config needs to be hosted on the same ESX host however.

  Oh, virtual networks are a separate issue, which allow the installation of a local network visible only to virtual machines in a configuration.

  I hope this helps.

• Issue of configuration of VLAN

  We have ESX Server 3.5.0 110181 and VIC version 2.5.0. Each of our ESX host has 4 NICs for use in our LANs, 2 more for each Port of the Console of Service VMKernel Port. Physical network adapters to connect to a stack of 5500 Nortel ethernet Routing switches.

  I am trying configure 4 NICs in each ESX host to be able to view the two VLANS separated. I am trying to configure these VLANS on the Nortel switches. The problem is I'm new on the VLAN and can't do network cards in the ESX host to always see the two VLANS. Right now I have an ESX host with two network cards that see both VLAN and two network cards who don't see a VLAN. I'm pulling my hair out trying to figure out what I did wrong.

  First and I realize maybe this isn't the best place to ask this question, but in the Nortel VLAN config, there are four choices of marking and I have not been able to understand that it is appropriate to use for the ESX host. The choices are; Removes all brand, removes the brand only PVID, Tag all or only Tag PVID.  Can someone help me with this?

  Also should I do at VIC or on the ESX host to see systematically the VLAN? The NICs appear to periodically just drag one of VLAN, generally the VLAN the DMZ.

  Any help much appreciated. This VLAN is new to me and I could not find very clear or basic info. on the configuration of VLANS.

  Thank you.

  Hi danzbassman, the best would be to put each of the 4 corresponding ports on your Nortel 'Tag All' or "UNTAG PVID." switch only

  If you use 'UNTAG PVID Only' on the switch, this means that all executives EXCEPT those on the VLAN "primary" assigned to the port should have tags on them. Then, on the side of ESX vSwitch, you want to create your virtual machine with the many groups entered the VLAN ID field for each VLAN "secondary" on the ports of Nortel and the VLAN ID field blank for the VLAN "primary". For example, suppose that your four NICs (attributed to vSwitch1) were connected to ports 1, 2, 3 and 4 on the side of Nortel and you had three VLANS, 100, 200, and 300, with VLAN 100 defined as the PVID on each of the four ports. If you want your virtual machines to be able to properly access to all three of these VLANs, to put in place three groups of virtual computer on vSwitch1 ports, one with the VLAN ID set to nothing (for VLAN 100 traffic, because it is not marked), one with the VLAN ID value of 200 and another with the VLAN ID value 300.

  If you use 'Tag All', then you would follow the same procedure, except your first port group (one for traffic VLAN 100) should also have its VLAN ID set to 100.

  Please, help me by awarding points for a 'useful' or 'proper' response if you think it is useful!

• Affecting several VLANS to a Port Group

  Hi all!

  We have 2 switches farm of server connections to the host server. Each of our 8 ESX servers has 4 physical network adapters that support virtual machines. We have 2 network cards to each physical switch. We have a single vSwitch and 2 port VM groups set up on each ESX Server. We use and configuration active / standby in Port groups so we can control what physical move the VM speaks to. All 4 network cards are available for the Group of ports, with connections going to spend 1 active and forward to switch connections 2. It is reversed on the other group of Port.

  We have several VLANS associated with our data center. Is it possible to put the tag VLAN on 2 port groups VM to support multiple VLANs? Otherwise, I think we have to put up a pair of these groups of ports for each VIRTUAL local area network, we want to make it available to the virtual machines on each ESX Server. Is this correct? We have some circuits/EtherChannel enabled on switches that work properly. However, we cannot port VM groups to pass traffic unless label them us, and it seems we can only enter a VIRTUAL local area network in the area.

  Thank you in advance for your help!

  To use the trunks that are coming in your ESX host, you must have your VLAN Tag somewhere along the way.  If you are not at the level of the switch (since you're trunking), you will need to do the vSwitch, either the level of the virtual machine.

  VSwitch level, this by creating exchanges and then marking at the level of the port group.  Marking that is currently happening in the ESX/vSwitch, and your vm must use the port suitable for group the VLAN they need to use.

  Your last option is to tag at the level of the virtual machine itself.  To do this, your vSwitch must use VLAN 4095 tag, which allows all the VLANS to pass through, and all tags are marked.  The portgroup vSwitch here is basically a tunnel and will allow the unmodified traffic, but now, you have to mark your VLAN of the NETWORK adapter in your virtual machine.  It is very effective if you have a large number of virtual machines.  The most practical method will be to create the VLAN-based exchanges at the vSwitch level and go from there.

  Unlettered, somewhere, communication will not incorrectly, as the physical switch will assume that all traffic not marked will even vlan uses unmarked frames (vlan native), and machines on that vlan can communicate each other.

• Linking the two vSwitches in ESX

  Hello

  I have a question.  I have attached the script with this post.   To set breiefly,

  (1) I'm having an ESX host with a single physical network adapter VMNIC0

  (2) I created 2 vSwitches with the default.  So totally 3 vSwitches it

  (2.1) vSwitch0 - dedicated for the Service Console and VMKernel and connected to VMNIC0 for external connectivity N/W

  vSwitch1 (2,2) - two virtual machines are connected over

  vSwitch2 (2,3) - two virtual machines are connected.

  Please note that the 2 vSwitches (vSwitch1 & 2) are not connected with each other and also unrelated to physics N/W adapters

  (3) the two VMS in vSwitch1 can communicate with each other without any problem

  (4) the two VMS in vSwitch2 can communicate with each other without any problem

  My Question is;

  How can I connect these 2 vSwitches (vSwitch1 & 2) with each other so that two vSwitches virtual computers can communicate with each other

  This question may seem very simple to most of you... I understand... but I don't know how to do this.  Thanks for any help/entries in this...

  Thank you.

  vSwitches cannot be connected together.

  If these clients must communicate with each other, they must be on a vSwitch. The traffic between two vSwitchws must pass through the physical wire. So you have at least two NETWORK interface card to connect two vSwitches as a teddy bear can only be connected to a vSwitch.

  You can always separate the guests using different port groups.
