dvUplink vmnic mapping?

Similar Questions

• VMNIC mapping

  Currently, I add another ESX 3.5 host in the cluster and I try to understand how the ESX maps physical NIC to vmnic.

  I started to do some tests and here is what I found.

  NIC = two on board and two PCI Intel quad NIC (10 physcial NIC)

  First of all, I plugged the CAT5 cable into port # 3 of the first PCI = vmnic0

  Secondly, I plugged another CAT5 cable into port # 1 of the edge env = vmnic1

  Thrid I plugged another CAT5 cable on port # 1 on the second PCI = vmnic4

  Finally, I plugged another CAT5 cable into port # 1 on the first PCI = vmnic7

  The port numbers that I use are all from left to right, just in case you ask

  Thanks for any help.

  Hi MLDAY, how it affects the numbers vmnic physical NIC ports depends mainly on the unit that you select when installing ESX. What that you choose in this dialog will have the value vmnic0, and all others will be numbered compared based on the identifier of the PCI. When you configure multiple, physically identical hosts, preferred to make sure to select the same device during installation to avoid confusion. Hope that helps!

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

• ESXi 4.1 or ESXi 5.0 with iSCSI SAN

  Hello

  I'm trying to establishing an environment that is / will be an iSCSI SAN backend entirely.  I know of a lot of reading that the best practice is to config the ESXi host with:

  VMKernel > vmnic > physical network adapter > switch ports > port on SAN (config 1:1 - no grouping of vmnic)

  Environment:

  ESXi 4.1 & 5.0

  Force10 switches

  EqualLogic iSCSI SAN (PS4000 & 6000)

  Here's my real question (playing the Devil's advocate):

  Why I shouldn't team 3-4 vnmics on a vswitch with multiple vmkernel ports?

  Given my environment.  Can someone point me to a technical document that explains what will / could happen if I set up the environment ESXi in this way?

  Thank you

  So, basically, we want the SAN to take full responsibility for the failover instead of the network and/or the SAN for who should resolve the failure (which could lead to the time of restitutio in integrum longer session).   I understand that correctly?

  Yes, that's right, we want to stack storage for vSphere manage with path selection and tipping - and by connecting each vmknic directly to the physical vmnic map we sort of "simulate" how to CF cards and also ignores the network failover mechanisms. As you probably know you also need to "bind" the iSCSI Software to the two vmnic (GUI now in 5.0, esxcli in 4.x)

• 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.

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

• Impossible to activate VMware Bridge Protocol on my broadband card

  Hi people!
  Quick little problem I have that I wonder if anyone else has met and solved.
  First of all, on my old D630 with XP, I got VMware Workstation 6.5.2 installed and was able to set up networking:
  1. use the card wireless (in a hotel) to VPN in Dell and
  2 at the same time to run a virtual machine that uses the broadband card to get out without a VPN'ing in.
  So two different internet connections with two different aims; one for my laptop and one for the virtual machine running on my laptop.
  Now, I have a new laptop with Windows7 and Workstation 7.1.3.  I noticed that the card integrated broadband has NO Bridge Protocol enabled VMware and so I can't select a dedicated vmnic mapped for my virtual machine.
  The solution (I thought) so to activate the Protocol.  Everything seems easy?  Fake, once I have selected the Protocol, VMware Workstation tells me to turn it off (see attached error).
  Any ideas?

  Thank you for updating this post as host

  so, to summarize: If you need jumpered with a broadband networks DO NOT use Windows 7 cards

• Need help to check the switch VMNIC and VNIC DVS mapping...

  Need help to check the switch VMNIC and VNIC DVS mapping...

  I checked the command net-dvs, but it was not useful.

  Thank you

  Ravinder Singh...

  You do not have access on the interfaces between itself or this info is not visible in vCenter? Probably, you should talk to one who is in charge of your nexus dvSwitch.

  I don't know how it works on the nexus 1000v switch, but the output of the net-dvs provides information on balancing policy for all ports (note that he understands the uplink ports that may still occur as "port id of virtual source"):

  # net-dvs. "grep EI ' (Balancing | port)"

  port 320:

  source port = load balancing virtual id

  port 321:

  source port = load balancing virtual id

  port 177:

  source port = load balancing virtual id

  You should also be able to enter this info from esxcli, but I don't know if there is a hook to esxcli for the link. Perhaps, you can branch off with cisco of dvs esxcli vswitch network or something. On the dVS of vmware, you could do:

  # esxcli dvs lacp vmware vswitch network status

  LACP is disabled on DVSwitch.

  
  

  # esxcli dvs lacp get config vmware vswitch network

  DVS name LAG ID cards active network Mode

• Migration to Cisco 1000v with portgroup Vmnic (almost there!)

  I am trying to automate the following steps so that I can configure networking for a host, end-to-end (using vCenter 5.1, PowerCLI 5.1 Release 2 Build 1012425 to PowerCLI 6.0 Release 2 build 3056836). The host has two network adapters physical, one of which (vmnic0) is obviously taken by vSwitch0 during initial installation. So, I need to:

  (1) migrate physical vmnic1 a VDS (1000v)

  (2) set the GRPE of ports uplink for vmnic1 in the "system-binding rising-vc02."

  (3) turn on the VDS called "vc02-vmsc" vSwitch1 to a portgroup vmk0 management network.

  (4) physical vmnic0 pass vSwitch1 a VDS, adding to the bond rising portgroup "rising-vc02 system-binding."

  I can only reach 1-3. I can handle a party of 4), moving the 1000v vmnic0, but only in the portgroup of 'Unused_or_Quarantine_Uplink' and not the one I need.

  I tried to repeat the code above this vmnic1 against vmnic0 objectives, but this indicates that the host is already member of the VDS.

• vmnic redundancy and UCS

  I use Cisco UCS with standard and distributed switches in VMware.  By port group vmnic how do I need?  The vmnic isn't actually physical NIC in this case, just virtual representations made by UCS to the virtual switch.  Is there any point in having more than one VMNIC by port group?  My dismissal is managed by UCS with map a VMNIC unique muliptle physical connections.  Have 2 vmnic in VMware create redundancy or performance gain or not only made it the design more complex?  Should I use a vmnic and UCS, make sure that a VMNIC able to use multiple paths physical if one breaks down?

  You will need two network cards, one per Module e/s, in order to provide a path to these two UCS fabric interconnects.

• Intel Server System R1304BTLSHBN (the map Intel mother, S1200BTL)

  Hello world

  I just bought an Intel Server System R1304BTLSHBN (based on Intel S1200BTL motherboard).

  I installed the latest version of VMware ESXi 5.0 Update 1.

  My 1st problem is that there are 2 network cards and only the #1 nic is recognized...

  I don't understand why.

  In the BIOS, the 2 network cards are recognized but in VMware ESXi 5.0 update 1, a single network adapter is recognized (nic #1)...

  It's very strange. The nic #2 light flashes as if it worked well.

  It would be very foolish if Intel have put 2 references of different cards, so I guess the 2 network cards are of the same reference.

  You have the same problem?

  My 2nd problem is this: I created a RAID 5 (to protect) on 4 hard drives to store my machines installed and virtual ESXi on a usb key.

  But in vSphere, I see 4 data warehouses (as if the RAID 5 has not been recognized. Each hard drives are recognized individually)...

  Please help me.

  Thanks in advance.

  Good bye.

  PS: Sorry for my English, I'm french.

  How hard disks are displayed (assuming that you have configured the RAID correctly in bios) means that you have a software RAID controller. ESXi only supports the RAID HARDWARE controllers. Any software RAID controller, which works with ESXi, will display only the individual drives in ESXi/vSphere.

  If you really need these disks inside the server host, you can buy a hardware RAID controller that is on the VMware HCL for ESXi 5.x... Otherwise, you're pretty much SOL here.

  When you look at the network adapters tab 'Configuration' of the host, is it only show a single vmnic from the map? If so, then I think you must either async drivers for the NETWORK card, or it is defective or damaged. Although a quick check on the VMware HCL shows the NIC as being 'Inbox' drivers under ESXi 5.x, so this probably isn't the issue. See if there is an update for the NETWORK adapter themselves for the server. This would be separate from the main motherboard bios updates...

• virtual network card to the physical network mapping and default loadbalancing

  What Virtual Machine virtual network card is map physical NIC.

  For example.

  lets assume Vswitch1 on host1 esx dedicated for the network of the virtual machine (port group) and it has 6 cards network linked to it (vmnic1, vmnic2, vmnic0, vmnic3)

  Load policy (default) Balancing - from the originating virtual port (it balances only outbound traffic through all the nic assigned to vswitch1 right?)

  ESXi host1 <-Vswitch1 (the VM network) <---(vmnic 0-vmnic 3)

  Lets assume that esxi hosting 6 virtual machines and each virtual machine has two network cards configured.  Through some documents, come out of that when the virtual machine is running, it gets connected to the ports of availabe on virtual swicth. say, I turn on the virtual machine in the order VM1, VM2... VM6.

  Vmname virtual adapter port on virtual switch1 Mapping of the physical network adapter                        

  VM1 eth0, eth1 1.2 which mappeed of the physical NIC to eth0, eth1?

  VM2            eth0,eth1                              3,4                                      ?

  VM3            eth0,eth1                              5,6                                      ?

  VM4            eth0,eth1                              7,8                                      ?

  VM5            eth0,eth1                              9,10                                    ?

  VM6            eth0,eth1                              11,12                                  ?

  Since we use load balancing based on the virtual port, can two virtual map of the same virtual machine are mapped to the two physical NETWORK card I want say eth0 VM1 is mapped to the (physical nic) VMNIC0, VM1 eth1 get connected VMNIC1 (physical nic).

  It would be great if you could explain how the virtual network adapters are mapped to the physical NIC Y at - it a command or a script to the list NIC(of all vms hosted on esxi) virtual NETWORK adapter mappings physical in detail.

  Is there a way to know what virtual NIC to connect to which physical NIC

  With the virtual NETWORK adapter, you hear the virtual card inside the VM? If if and when you use several VMNIC like you, there is no visibility in vCenter (usually vSwitches, we see with Distributed vSwitches).

  However, you can use the command-line ESXTOP tool in the view 'n', for the connection between the virtual machines and the outgoing vmnic.

• Re-order the vmnic in ESXi 4.1 u1?

  I have a Supermicro 1026 t-6RFT +. It has 4 onboard NIC, 2x1Gbps and 2x10Gbps. I also added a map of port quad Intel E1G44ET2.

  4 NIC onboard were picked up during installation. The E1G44ET2 required for an update of the driver to see their ports. But now my vmnic is numbered in all directions out of sequence.

  Can vmnic be somehow rediscovered after installation? Maybe empty what's there, restart, then auto-sucer that hide them well?

  You can manually edit the esx.conf file to reorder the numbering of NIC - http://kb.vmware.com/kb/1971044.

  You can activate the Mode Tech Support access to the console or enable SSH access.  Alternatively, you can copy esx.conf copy in PC management with the vCLI or PowerCLI, update the file and copy it to the host.  Once you have made a change, you will restart the host.

• Mappings of vmnic to psyhical NIC issue

  Hi all

  I was just wondering how ESX maps to vmnic cards network pyshical and if there is anyway to change that.  I have 4 servers with 2 onboard network cards and 2 cards broadcom.  All except 1 server have a vmnic0 & vmnic1 defined as the onborad and network broadcom as vmnic2 and vmnic3 cards.  The strange server ball vmnic0 and vmnic2 as the on-board NICs and vmnic1 and vmnic3 as the broadcom.  Is there a way that you can change that or is this mapping / allocation to occur when the system is installed or the network card is installed?

  I'm not 100% certain about how ESX binds to a specific NETWORK card during the installation, you can choose what Teddy you want be vmnic0.  However, you can easily move things.  If you move natachasery on your Service Console, I had to first put the host in maintenance mode and then access the Service console via a kind of remote control as DRAC or ILO.  You lose connectivity to your VIC.

  You want to use the esxcfg-vswitch command.
