Management on a distributed switch network

• Distributed Switch vs switch Standard

  Hey all,.

  I was wondering if someone could answer some questions for me on distributed switches. I've worked with vmware for a few years now, but believe it or not I've never configured a distributed switch. The environment I work in always used standard switch, and when you're dealing with people who have the mentality of "if it ain't broke...". ', it is easy to become complacent. Everything in my environment is 5.1 incidentally.

  I read various articles on capacity now, but I don't have a test environment to break, so I have to pay attention to any changes I make. I thought it was better to ask those who are familiar with him before deciding on future changes.

  -What I lose any host on network management (what I used with switches std) as soon as I create a distributed switch?

  -Distributed is vCenter wide switching, or can I create several switches distributed by cluster, or only with certain subnets included?

  -What happens when I add a new host in a cluster with a distributed switch? It is automatically get set up with the distributed Switch networking capabilities?

  -Are there pitfalls or problems I should be aware, either when creating a distributed switch or in the day-to-day management of the/them?

  -What is the best thing that I win? Worse, I've lost?

  Thanks for your comments.

  Hello

  To answer your question:

  (1) so you don't lose everything as soon as you create the switch. You can create a vDS (assuming that licenses) at any time and configure / play with him. Until connect you hosts and uplinks, so it is a pretty useless component in vCenter.

  (2) a vDS is wide vcenter. However, you can create them individually if oyu want. That is to say - one for the traffic of comments, one for management, one for storage.  You can also have them by cluster if you REALLY want to and just add the hosts in this cluster in particular switch that you built. But reducing to zero the point of them a bit.

  (3) when you add the host, you will be asked what you want to use, if you want to migrate all the standard switch VMK interfaces and if you want to migrate VMs. ACE as soon as this host and its specific uplinks are on the switch then the host will be able to use the vDS for everything you have set for rising connections.

  (4) didn't really create them. Some people are a little cautious host management of investment (usually vmk0) on them, some people are not. In general, the rule is that with a vDS you can not manage it if vCenter is down. But with a vSwitch you can connect to the host directly and set it up in this way individually. There are traps in this respect of binding of static ports on the port groups, but it can be bypassed by the binding of ports muralism on the management ports group. Chris Wahl explains better than I've rambled

  (5) the best thing you can is to have a centralized management and create groups of ports. You have a new VLAN? Need a new group of port? Simply create once for the vDS and it applies to all guests! In addition, you also get control network IO, where you can assign actions to specific types of traffic and other goodies that are not available on standard switches. I would say that you lose much, vDS if you have the license and and a fairly large area are the way forward management. Trying to think really inconvenience but I can't!

  Happy to help you further!

• 'upgrade' control of Distributed Switch for network IO / LACP improvements via PowerCLI?

  vSphere 6.0.  PowerCLI 6.0 R1.

  
  

  After using the New-VDSwitch PowerCLI command, I noticed that the Web Client vSphere shows there are "updates available" to the distributed switch resulting.

  
  

  I know that I can right-click on the distributed switch and select upgrade in the Web Client.

  
  

  Someone knows how can I perform the upgrade using PowerCLI?

• Configure VTEP VXLAN on distributed switch?

  Hello everyone

  I've found this discussion: How to test VXLAN

  But I'm still not sure.

  I environment vSphere 6 with a 3-node cluster and server vCenter (trial mode).

  I would just try the VXLAN by adding a VTEP to a distributed switch.

  For each of the nodes would be a VTEP.

  I really should he use Manager of NSX and NSX controller etc. to achieve this, or is there the possibility to simply add a VTEP to a distributed switch?

  KR & thanks in advance!

• New to distributed switch necessary Clarification.

  Hi all

  I need some clarification.

  Have created a distributed switch, in my lab, which was created without any problem.

  I have 2 hosts in my lab host A and host B.

  There is no vmkernel ports to migrate, so away I went to Setup - network - Distributed Switch - manage e-cards and created a host A vmkernel port.

  But when I goto host B Configuration - Networking - Distributed Switch, I am not able to see the vmkernel port I created.

  I need to create the port on host B manually vmkernel group? I was under the impression, the port of core, I created on host A would be automatically visible to host B?

  That's where I need some clarification, so that, from now on, I am being harassed by this.

  Any clarification would be appreciated.

  Thanks Andrew for the clarification, much appreciated and its clear now.

  Port Comon group

  Core groups (e-cards) must be configured individually on each server.

  Do not crack.

  Thank you once more for confirmation

• Question about distributed switching

  Currently, we run a mix of ESX 4.0 host U2 and ESXi 5 U2.  vCenter is version 5.  Most host NIC are 1 GB.  vCenter virtual switches are configured as standard.  We must

  reduce the number of ports Cisco asked our network group where they are at a premium.  Some tests were conducted using the VIRTUAL local area network ports.  Distributed switching

  more that simply centralize network management in vCenter?  It does not reduce the number of NIC host ports or each host still must have his own physical

  connections to networks, he needs to talk about?  What are others doing?  Thank you.

  IT does not reduce the number of physical ports on the host - hosts still needs physical connections to the different networks / VLAN.

• Need help distributed switch

  My lab at home is built entirely in ESXi 5. In other words: a physical host with two VirtualHost ESXi ESXi 5 remaining with at. My data store is a race off the coast of SAN virtualized FreeNas.

  The question that I meet is when I create a Virtual Switch distributed and the establishment is looking for a physical network card. Is there a way to get around this? I could create a vDS to a virtual NETWORK adapter? If so, how?

  Your help wil greatly appreciated.

  The wizard could cause the interruption very you speak if she were to offer this option ;-)

  In avoiding or minimizing disturbance is a challenge of the migration of the distributed switch standard, in a lab like this is less of a concern, of course, imagine if it were a production environment! If you were to follow an approach to the real world, you would look to have all your switches using grouping of NETWORK cards in a first time, the process would be:

  0 migrate virtual machines on a host

  1. remove 1 NETWORK card in the standard switch NIC team

  2. create the distributed switch and add the host by using the NETWORK card removed in step 1 as the first uplink

  3 migrate or create the ports for the distributed switch group

  4. remove the remaining standard switch NETWORK card and add it to the distributed switch

  5. proceed to the next host

  I would complement the management process of network cards on a per host basis, of course, you just create a single switch distributed in total.

  Who is?

• Switch std to distributed switch migration.

  I have 2 Dell T710 with 6 NIC cards.

  I configured on the 4 standard vSwitches.  Each standard vSwitch is connected to a physical network adapter card.

  I have a vSwitch for manage management, one for vMotion for iSCSI and one for traffic from the virtual machine.

  The reason I set up is to put the vMotion, iSCSI on a different NETWORK card and so another port on the physical port in order to get the maximum flow.

  Now, when I tried to configure a switch to vDistributed.  I was reading this document from vmware (http://www.vmware.com/files/pdf/vsphere-vnetwork-ds-migration-configuration-wp.pdf) and there seems to be all the VLAN based.  In the vDistributed switch, I create the port group, and then associate the group the dvUplink ports and the dvUplink will map to the physical NETWORK adapter on the host.

  I don't seem to find an option to specify the Group of ports on the dvPortGroup if East of vMotion, management and/or iSCSI traffic.

  I'm missing something.

  Can someone tell me some good practices of switch vDistributed?

  Thanks for the information and have a good year.

  Anthony.

  You will need to go to the host tab configuration, management network, distributed switch - then "virtual cards" - the Vmkernel ports for the distributed switches.

• vNetwork Distributed Switch - School me please!

  Can someone give me a description as to what is happening with a configuration switch vNetwork?  My areas of interest are:

  What happens when I add an ESXi host management network interface active to a distributed switch?

  How are the hosts of ESXi with several NIC supposed to be configured on the physical network?

  Should I have several ESXi host WHAT NIC connected to VLAN separate physics?

  When and how to use groups of dvPort?

  What is the best practice to deploy a vNetwork Distributed Switch in a production environment existing?

  What IP addresses should the virtual machine which will connect to the switch vNetwork have?  Real routable IP or a private beach that lives on the only host of ESXi?

  I have ESXi setup guide and understand 'how' do these things but don't understand what happens when treating several VLAN virtual physics and ESXi hosts being not connected to all local networks.  I tried to set this up a while ago and had a lot of questions while losing connectivity to multiple hosts ESXi and all virtual machines running on the hosts on the network.  I don't want to repeat this mistake!

  You don't have to use the junction of your physical switch ports, it is usually best if you do. When you use the junction ports and assign several VLANS to that port, that means that the virtual switch (standard or distributed) can then talk to the physical switch using assigned VLANs. Which means that a single physical NETWORK card within an ESX host can talk to several VLANs, if you do not use trunking then you can only assign a VLAN by ESX NIC that is not very effective.

  Most of the vSwitches converses with several VLANs, but will have only one or two uplinks, in this scenario, it is almost always necessary to use port trunking.

  Does that answer your question?

• VSS migration to virtual Distributed Switch configuration

  Hi all

  I am trying to wrap my brain around that and just run into a few problems actually make things work. Please bear with me, I will try and describe the environment that I have and what I'm trying to building with like jargin little I can.

  My current vmware environment consists of 3 hosts vsphere 4.x and about 6 different subnets. My primary host vSphere is home to the largest part of the virtual machine and manages 5 different subnets connected to each of 5 virtual switches separated with 1 assigned to each NETWORK adapter. Also, there is a switch of kernel VM with a connection to my NetApp iSCSI. The other vSphere hosts are simple enough, the two are connected to subnet 1 with a virtual switch for it and a switch of kernel VM with a connection to the NetApp iSCSI.

  Each subnet in my lab is managed/break through the VLANS on Cisco devices, so I saw that it had to assign any settings VLAN since the power of VMware.

  If you refer to the VMWare vNetwork Distributed Switch: Migration and vmware Configuration guide, I am trying to migrate a seup similar to this:

  

  However, I'm running issues when you try to get the int hosts a vDS configuration. I could create a vDS for my root subnet, add one of my hosts vSPhere and migrate the virtual machine to the new port group in this vDS. The Service console as well as the VMKernel remain virtual switches on the host and I can't understand how these migrate to a vDS host without lose the connection.

  I'm asssuming based on the number of subnets that I manage between hosts, I'll finish with about a 5-switch vritualDistributed for subnets, each with at least 1 card a vSphere host physical NETWORK link up to the appropriate subnet. In addition to this, I'm assumining I'll need to create a vDS for the Service console and VMKernel (iSCIS) traffic. The Service Console are on the same subnet, some VM most residence on that subnet, separate VSS was created on the hosts to manage separate traffic.

  Any help anyone can provide on how to create vDS for SC/vmk traffic and get the associated host migrated to which would be very useful. As I said I was able to create 1 vDS and add a host computer via 1 uplink NIC with the virtual machine, but nothing beyond that seems bad connection.

  Feel you please free to ask for additional details, I know it's a lot and maybe a bit confusing. Thank you.

  Hello

  If I'm correct, when the host is added the vDS and the creation of the vDS Service Console, I have to select an unused NIC and migrate the SC existing to the new group of port... or should I add a second SC for the VSS by using a NETWORK card available and who migrate to the new vDS?

  Yes, select an unused physical nic so that you have a physical nic connected to the VSS and the other to connect to the uplink of vDS group and migrate the SC. existing if you have several hosts, vMotion all VM and test to see if the migration without distruption, also works to keep details of the ILO ready incase you need to connect to the console of the server.

  This is a very good book white http://www.vmware.com/files/pdf/vsphere-vnetwork-ds-migration-configuration-wp.pdf that provides detailed information about the migration.

  All the best.

• Distributed switches

  Hola amigos tengo una duda con los switches distributed, probably will be una tonteria.

  Exactly, what application practica podemos dar a los switches distributed?

  What el siguiente caso, ellos uno? :

  I have 2 ESX, y cada uno tiene 4 cards of red than configurated siguiente manera in each of ESX:

  • 1 con vSwitch 2 cards, una en Eve y the other campaign Online that offers service of VMotion + Console Service
  • 1 con vSwitch 2 cards, una en watch y Online other than Máquinas Office service offers.

  Ahora tengo the use una tarjeta red necesitat para otros usos, por example para servicio offer an otras s VM. No tengo tarjetas free Red y tampoco tengo € buy nuevas tarjetas para... . ¿Puedo use switches distributed para lo siguiente? :

  Set a switch e between ESX para that use back red tarjetas para VMotion + Console service. In this way, me sobran back red antes tambien antrs tarjetas para VMotion there Console of Service.

  Realmente, asi works ¿esto? Puedo tener back UN ESX red tarjetas para as por ellas pase el trafico of Service Console del donde estan instaladas how ESX + VMotion y también del otro ESX?

  En fin, son dudas existential...

  Kind regards!

  Hola XC:

  Aquí tienes a document than explica vDS http://www.vmware.com/files/pdf/VMware-vNetwork-Distributed-Switch-DS-EN.pdf

  None are known only homogeneizar feature the config between hosts (important in large despligues) sino that also added a mas virtualizacion del chemistry control networking.

  Algo a muy into account when usa is vDS, are as vCenter has to be HIGHLY AVAILABLE. The administration of esta feature is through vCenter, por lo if hace este falla y no is tiene acceso a tampoco el is podrá manage vDS.

  A greeting.

• VNetwork Distributed Switch virtual cards

  Trying to get my head around e-cards in the distributed switch.

  In standard switch, I understand the hierarchy like this:

  vSwitch (upper level)

  groups (including the kernel) port (2nd level)

  physical cards (identical to "vmnic..") (join vSwitch)

  I do not understand the hierarchy for the distributed switches.  The use of the term virtual card throws me a loop for.  I consult the virtual map of term as something that you "attach" to something (vswitch etc...), not something you add.  For example, when I go in manage e-cards and select migrate existing adapters, I give you the choice of console and vmotion.  I find the console and vmotion as groups of ports and not e-cards.  Any help to understand this would be appreciated.

  Thank you

  From page 36 of the Guide de Configuration ESX (http://www.vmware.com/pdf/vsphere4/r40_u1/vsp_40_u1_esx_server_config.pdf):

  Virtual network cards manage services network host on a vNetwork Distributed Switch.

  You can configure the console service and VMkernel virtual cards for an ESX host by a partner

  vNetwork Distributed Switch or by creating new virtual maps or the migration of existing virtual cards.

  When you migrate a virtual network adapter, you should migrate the service or VMkernel console since a standard vSwitch to a group of ports in the vNetwork Distributed Switch.

• VMware Distributed Switch with VLAN

  Hi again,

  A lot of work with VLAN now.

  But just a quick Questions. Is there a documentation or HowTo Guides how to set up vSphare VMware Distributed Switch with several VLANS on a Switch GS724Tv4?

  

  But soon, I try to add a host or network, it is empty.

  This is probably an easy problem of VMware, but I try here first to see if someone has document guide HowTo so I can start with.

  Thank you

  Never mind about this,

  I found the problem on my own, but perhaps a documentation would be great to have. But it's a good start to have the right license of VMware, before you start.
