behavior of vSwitch in Virtual Switch Tagging (VST mode)

• External Tagginng switch vs Virtual Switch Tagging

  Hello guys,.

  I'm really confused about these modes of two configurations and their uses / consequences.

  Say you have four natachasery and configure the vSwitches in the following way:

  • a vswitch with service console port group (vmotion) vmkernel port group and group of ports defined VM and four natachasery in annex

  All three services (SC, vmotion and vmtraffic) are in the same network (e.g.: 192.168.1.X), so all the natachasery is attached to the physical integrity go to this VLAN.

  In this scenario, I guess I'll use IS, right? I have to configure something in the physical switch (like the 4 natachasery trunking)? Or just nic teaming four cards in the vswitch network is enough? Or both?

  =======================================================================================================

  Now say you have 6 natachasery and configure the vSwitches in the following way:

  • a vswitch with defined service console port group and two natachasery in the annex

  • a vswitch with Group of ports vmkernel (vmotion) and two natachasery defined in annex

  • a vswitch with Group of vm ports and two natachasery defined in annex

  Each service has its own network, but now you have the production and DMZ VM.

  In this scenario, I guess I'll have to do the following (get ready cause its really confusing, at least for me):

  (1) set two NICs in the pswitch, firstly in the vlan management and in the nic vswitch team these two network cards. If you use felt

  (2) attach the second pair of NICs in the pswtich, in the vlan vmotion and nic vswitch team these two network cards. If you use felt

  (3) fix the last pair of network adapters in the pswitch to two ports that don't have any definied vlan on it and then to create two groups of ports in the vswitch: one for the VM of the production and the other for VM DMZ, marking with the right VLAN ID and nic team these two network cards. If you use the VST.

  Edit: I realized that I could simplify the second scenario, saying that the three services would be in the same vswitch with 6 natachasery attached to it, but with four networks. And fix these 6 cards in the pswitch with no VLAN defined in these 6 ports.

  As you can see, I'm pretty new in this kind of things, so, if I'm wrong to speak of something (or all), I'm sorry.

  I have attached two Dummies to try to be more clear.

  Excuse me for my English

  In the first scenario, you are right.  No obligation to trunk.  On the other hand, I myself prefer to use trunks for all my connections, with all of my virtual local networks available on all of my trunks.  In this way, if I need to spend my autour natachasery, ever, I can do without the participation of network.  If you yourself control the network, then this isn't a problem.  Of course, this is not required, the way you have your first scenario presented will work fine.  And by the trunk, I mean a 802. 1 q trunk in terms of cisco, as opposed to a trunk in terms of HP, which would be an aggregation of links 802.3ad.

  In scenario 2, only the vSwitch vm network exchanges where you need multiple VLANs is where you need the trunk.  Make sure just that the VLAN native on this trunk is different.  In addition, you need to configure the ports as an access port (which means that the port will be part of a single VLAN) for the management VLANs, or a trunk with several port VLAN allowed.  Other than that, there should be no problem with VLAN marked and unmarked.  I use them all the time.

• Switch tag vlan

  Hello

  I'm install esx 5.1.

  I have 3 vlan (prod, vmotion, vmkernel). I am glad that when I put vlan dcui (yellow form) correct, that I can not ping host esx. If Iremove vlan tag I can ping esx host.

  I suspect that someone does not work on the switch (not run by me).

  How can I help the team network? What game on the switch port network team must be defined?

  Thank you

  Your network team should create a 'trunk' for physical network ports used by ESXi. On the trunk, they should allow these 3 VLAN mentioned above. Now, I guess they did but you "VMkernel" VLANS is equal to your regular administration VLAN, which is also be the VLAN native.

  So I think that there is nothing 'wrong' with your configuration, it's just an implementation detail... If the "management VLANS" also happens be the VLAN native side effect is that you do not need to specify a VLAN ID on the portgroup.

• Can not pass traffic with label of vmware virtual switch fabric 10 GB

  Hello

  I need to understand how to move traffic labeled VMware VST to these virtual Fabric switch. Blades IBM HS22 connecting internally to the virtual switch between ports 1 to 14. I use 2 external ports (17-18), one connects to the Netgear switch and another to the other switch to virtual fabric. Did the same on the other virtual fabric switch. My Synology rackstation is configured with LUN iscsi that connect to the Netgear switch and I would like to connect my HS 22 rackstation blades. My main concern is that I can't ping the IP of netgear on the same interface vlan. I can ping my Synology diskstation to the netgear which are in the same vlan. NETGEAR and BNT switches are connected by cables DAC SFP +.

  

  Even VLAN is also configured on Netgear switch. The default pvid is set as 1 on all interfaces, can I disable this? Do I need to use tagpvid-penetration on all interfaces.

• Cannot set trunk on my virtual switch port

  Hi all

  I have setup a host ESX VM 2 and a virtual switch (vSwitch0). Each VM has 2 vNIC (Admin and Public). I created 2 groups of ports on vSwitch0 with VLAN ID 2 (Admin: Public and 10:20).

  So that each vNIC VM goes to a VLAN. Now I want to create a trunk between my vSwitch and my physical switch.

  I set up the trunk of the physical switch port but I have not found how to set up the trunk on the vSwitch0.

  You can guide me please!

  Thank you.

  Welcoem to the Forums - there is nothing you need to do - it's automatically handles by the VMkernel - circulating packets throw vmnic0 will be approriately tag to each vlan 10, vlan 20 or unmarked for console, vmkernel and service traffic

• Distributed Virtual Switch supporting guests with different numbers of natachasery

  Our environment has had the same ESXi host model for some time. Each has interfaces from 2 to 10 GB for the traffic of the virtual machine. We use a virtual switch distributed with 2 uplinks. Now, we stand at a new environment where there are 2 types of hosts. (1) a small workload ESXi host with interfaces of 2 to 10 GB and (2) a large load of work sESXI host with 4 to 10 GB interfaces. They are seperasted in 2 groups (large and small workload workload).

  I had planned to share a Distributed Switch between the 2 groups, so I could move freely between them according to the needs. The only distinction of level of ESXi host is the power of horse and the I/O bandwidth (storage and networks VM will be used will be the same). It dawned on me that the distributed switch is configured with a particular number of uplinks. I'm trying to picture how this will work in this situation? I thought that I create a vSwitch distributed with 4 uplinks and finish by only using 2 of these uplinks when adding a small amount of work ESXi host to it. This is a valid configuration. Should I disable or do something special with the uplinks unused? I have not met this configuration so I wanted some tips on the correct configuration.

  I have validated this configuration as described previously. A dVS with 4 uplinks can take care of the guests with "up to" 4 interfaces. Hosts with only 2 interfaces will have 2 of the 4 links rising dVS associated with natachasery while the other 2 will remain unused. In my case, I decided to use the uplink 1 and 2. Uplinks 3 and 4 are not used with these hosts.

• Distributed Virtual Switch 5.1 update

  Hi all

  We have a vmware vsphere Cluster with 7 v 5.1 ESXi hosts 838463

  We have the form of upgrade version 5.0 to 5.1 ESXi ESXi and vCenter Server since version 5.0 to 5.1 September 2012.

  Now, I noticed that (just a little late...  ;-)) all the distributed virtual switches (we have 2 DVS) need to upgrade.  Version of DVS resulted, in fact, to be 5.0.

  (I saw in vSphere client connected to the server vCenter Server - networking).

  I wasn't expecting this behavior, DVS independent upgrade of host or vcenter server upgrade?

  It is possible DVS upgrade during the normal activity of the infrastructure?

  Thanks in advance

  Anna

  Think about the situation,

  don't forget that a dVS is a virtual switch split on all hosts, if the dVS has been automatically upgraded to the new version and there were incompatibilities or new features that were not available in the switch downstream you might run the risk of a network outage.

  in my opinion rightly done VMware cela a phyiscal post upgrade task,

• Consulta mejor opcion para configurar networking "virtual Switch".

  Hola todos espero esten very well...

  Tengo una consulta tengo q instalar 4 ESXI vphere 4.5 en mi granja servidores para el cual tengo q hacer ESXI a cluster are q el material nuevo are muy diferente al los servidores ago instalados.

  Tengo una consulta con respecto a part of networking

  nosotros tenemos currently assigned a con x amount of vmnic virtual switch a virtual swicht este para los servidores in una vlan especifica

  Office of y tambien tenemos otro con virtual switch x amount of vmnic para our Máquinas, o sea maquinas office q usan como desktop users con otro vlan especifica

  hace poco lei q best practices keep comunicación en esta era una en UN virtual switch solo?

  Partamos respond as las best no son solo eso practices, good practices there no estan en piedra, por cada uno debe set so what requested una best practice in particular to asil o has nuestro stage o an our needs.

  Dejando en esto claro, you have several options, partiendo por the config as you currently have there than in any caso esta mala.

  Según lo than tiendo tienes 2 vSwitch, uno para servidores office y otro para escritorios office, con cada vSwitch a number x of physical NICS.  Esta config you permite urban el trafico ambos types for office, asegurando además cierto nivel redundancia the conexion en Máquinas.

  Otra opcion, works that you are using VLAN, you have a vSwitch solo con todas las NIC that usan los 2 vSwitch configurados currently.  In unico vSwitch puedes crear este 2 exchanges, cada uno con una VLAN para urban el trafico las maquinas office, para lo cual las NIC physical deben estar his in modo los fisicos, pasando both switches trunk VLAN.  Esta config you permite una mayor red redundancia marine y ancho Mayor of banda, use todas las are for VLAN cada that could cards available for en el vSwitch network.

  Both options igual son of validas y lo you depende Niños y como are the Red architecture of you plataforma.

• Configuration of virtual switches that are not updated

  In a vSphere infrastructure 5 based on 2 servers ESXi 5, I moved a few virtual machines to one virtual switch to another.

  Virtual machines work very well.

  If I use vSphere client and look at the configuration of the hosts (host and cluster-> Configuration-> Networking) I see some VM as they were connected either the old virtual switch and the new virtual switch, while they are only connected to the new virtual switch.

  I press "Refresh" without any result.

  If I look at the properties of each virtual computer, I don't see the link to the new virtual switch.

  How can I solve this problem? It is dangerous, even if it does not affect VMs or virtual switches, because it can make operators make mistakes...

  Concerning

  Marius

  Nothing dangerous. You probably have Active snapshots on virtual machines. Once the snapshots are deleted, the 'old' vSwitch and port group will disappear.

• How to restore a distributed virtual switch.

  Hello

  I have a question where one of my esx host 4 i crashed and then we rebuild the host vmware and I have the backup of the file esx.conf with me since the day before. I had a virtual switch distributed in the vmware environment, and since I rebooted the backup config that my vcenter does not add the host esx to the distributed virtual switch.

  -How to restore the vswitch distributed on the esxi host settings.

  -When I look on the esxi configuration host configuration file indicates that DVS information are uploaded but vcenter does not overwrite the new settings.

  troubleshooting performed up to now

  I restarted the vcenter and all services and same problem.

  forced file configuration several times and same question

  has taken the esx host that out of the inventory and the same issue.

  any other suggestions.

  The answer to this has been found in Vcenter 5.1 where there is an option to save the DV switch. I connected this bug a few years back with vmware and this problem is fixed in vcenter 5.1.

• A large flat Virtual pass vs several virtual switches

  experts,

  What is the advantage of having a large flat Virtual pass Vs several virtual switches for all types of traffic of the virtual machine (management, Vmotion, Vm Network). Any improvement in performance.

  What is the advantage to have the virtual machine and networking on two different VLANS.  improved performance or security?

  Our current configuration has a virtual switch with all eight physical NICS are assigned.

  Vswitch 0 <-vmnic0, 1, 2, 3, 4, 5, 6, 7

  |

  Management network (Vlan 100) <-Vmnic0 (active), Vmnic7 (at rest)

  |

  VMotion (Vlan 150) <-Vmnic7 (active), Vmnic 0 (standby)

  |

  The virtual machine network (vlan 100) <-Vmnic1, 2, 3, 4, 5, 6 (all active)

  We will be setting up a new environment Vmware (5.0) and I would like to configure two virtual switches as follows

  Vswitch 0 <-assigning two physical network adapters (Vmnic 0, Vmnic 7)

  |

  Management network (Vlan 100) <-Vmnic0 (active), Vmnic7 (standby)

  |

  VMotion (Vlan 150) <-Vmnic7 (active), Vmnic0 (standby)

  And allowing that Vlan 100 and 150 Vmnic0 and Vmnic7 traffic

  Vswitch 1 <-assignment remaining interface cards physical network (Vmnic1, 2, 3, 4, 5, 6)

  |

  Computer virtual network (vlan 101) <-Vmnic1, 2, 3, 4, 5, 6 (all active)

  Allow only the Vlan traffic 101 on above NIC

  I am thinking propose above configuration.  If I go with above setup, I get an improvement in performance? or other benefits. Please explain?

  I don't think that there should be no difference in performance in the two installation options that you have. The only advantage to create two vSwitches would be to simplify the configuration, less risk of errors if Setup lots of armies and easier to check quickly as the configuration is correct.

  A small advantage with the creation of a large vSwitch is that you could (if you wish) experiment with the help of multi-NIC-vmotion in ESXi and assign several VMNIC for vMotion and it would be easy to give the VMNIC 'return' for the virtual machines more later if wanted.

• Network management - only the virtual switch

  I installed latest ESXi 4 Update 1, which is available. I m running Active Directory LAB on several virtual servers Windows 2008 R2 and one of them acts as a router with RRAS role. I m creating 3 different subnets and one of them must be only virtual - no material connection NIC in the interface of ESXi´s it seems that I can't do this, while creating the new switch virtual it forces me to select NIC it becomes a problem, because if I use a virtual switch for Windows 2008 router has the physical NETWORK map It will come to mean that the cable is disconnected. And I need a virtual connection between virtual servers only, that they will be the single subnet between them and communication to physical clients will go through this router´s of Windows 2008 NIC that is not supposed to be physical.

  How can I archive with ESXi?

  You can create a vSwitch without attached Teddy.

  Do not select any NIC, or delete them after the creation of the vSwitch.

• Virtual Switch Standard virtual Distributed Switch migration / a physical Uplinku

  Hello community,

The problem is I onlyy a uplink public and I can't add the physical NIC as the standard switch and distributed virtual switch. IAM looking for a way to migrate the portgroup & physical uplink NIC in one step. Someone knows how to do this without adding a second NIC uplink? Please keep in mind that my vCenter is a virtual machine on this machine.

  Thanks in advance,

• Advice on how best to configure the network adapters and virtual switch in ESX host

  I'm new to VMware and am its implementation.  I got my training a few weeks ago, and now I'm configing my hosts.  I have 3 guests, each have 2 network cards.  There is a virtual switch that ESX creates when it is installed (vSwtich0).  The books said that it is advisable to delete the VM network port of virtual machine that is assigned to the value group default virtual switch and put it on another virtual switch so that you keep your management network separated from the network of the vm for performance and security.  If I do this, all my virtual machines will have to go to 1 NIC b/c I only have 2 NICs per host.  I thought that I have just to keep all my groups of ports on the default vSwitch0 and add my second NETWORK adapter so that I can take advantage of the Association of NICs for redundancy and load balancing.  However, I'm not sure on the performance and the security risks.  Do you have any ideas or advice?  I could also create two virtual switches and put my virtual machines on one which would have a NETWORK card dedicated and put my service and Kernal VM console on another virtual switch with a dedicated network card.  However, in this scenario, I have no fault tolerance or load balancing.  We are a small shop and we have about 10-15 VMs on each host.  I don't have access to b/c distributed switching we paid only for the company (not more).  Thank you.

  Hi and welcome to the forums,

  With 10-15 VMs per box and I guess that I would seriously consider adding two extra cards for each host in the production machines. You could then do something like:

  vSwitch0 - vmnic0, vmnic2, vmnic3 - Console of Service, VM LAN network

  vSwitch1 - vmnic1 - VMkernel

  That would give you redundancy and performance to access your hosts (SC) and also for all your virtual machines. The VMkernel would get a NETWORK card dedicated for vMotion and could be on a separate network. He didn't need redundancy really as if the NIC sank the only issue is that you cannot vmotion virtual machines. In this case you would just move one of the NIC workgroup through to those switches manually.

  If you only have 2 network cards, then I would say having a vSwitch with two attached network adapters and VLAN the VMkernel may be off. I want absolutely to the redundancy of having two cards together.

  Hope this helps,

  Dan

• How can I assign some VLAN in Virtual switch?

  I have ESX 4.0 installed on two IBM Blade hosts that are in a HA cluster to enable vMotion.  I have a virtual switch created on each host.  Virtual machine connect to the same switch.  I added a new virtual machine to on one VLAN separated.  I have a few "How to"... questions:

  1. How can I put the new virtual machine in an assignment of VLAN different from other virtual machines?  (I think it's through groups of ports but I always read)

  2. can I put several VLANS on the whole virtual switch? (If Yes, what is the snytax? "43; 40 "or"43, 40' or "43-40")

  3. What is the best practice for this kind of Setup?

  Thank you

  Stuart

  Hello and welcome to the forums.

  1. How can I put the new virtual machine in an assignment of VLAN different from other virtual machines?  (I think it's through groups of ports but I always read)

  Port groups - you're right.  Create a port group, and then assign the virtual machine this connection.

  2. can I put several VLANS on the whole virtual switch? (If Yes, what is the snytax? "43; 40 "or"43, 40' or "43-40")

  Yes, you want to create a new port group for each VIRTUAL LAN required in the vSwitch.

  3. What is the best practice for this kind of Setup?

  There is a lot of information around this in the Guide de Configuration ESX.

  Good luck!
