• How to view the vswitch on ESXI 6.0 mac address table?

  Hello!

  Is there any medium vswitch to view for all (or special) mac address table CLI?

  It is very useful in troubleshooting scenarios, but I can't find how to do it.

  Thanks in advance!

  ESXi virtual switches are not manageable switches.

  You can query to switch using the vSphere API, see this - http://www.virtuallyghetto.com/2011/05/how-to-query-for-macs-on-internal.html

• ESXi 4.1 DHCP and Mac address problem

  I'll put up my new hosts ESXi 4.1 using reserved IP address of the DHCP server

  Linking the ip address to the mac address of the host.

  The mac address is related to the physical NETWORK card mac address.

  When I don't see NIC 0 and NIC 1 resumes, guests will receive a different IP address.

  How can I solve this problem?

  Thank you

  This is a Ko for this problem.

  I hope that you ENT + licenses to use the profiles of the host.

  Will save time

• How to set a specific MAC address for a virtual NETWORK adapter in ESXi 4.1?

  I would like to move a virtual machine to another server ESXi, but I saw every time I use the converter, it changes the MAC of the virtual network interface! Also if I copy the virtual machine to a vmware 2.0 server the same thing happens. Is it possible to keep the same address in another computer and turn off the virtual machine from the first computer source to avoid conflicts of mac?

  Thank you.

  Using the converter, you'll always end up with a different MAC address. If you just want to "pass" the virtual machine, you can use utilities like of Veeam FastSCP.

  Another option is to set up a MAC address in the network settings of the virtual machine. After conversion, you can reset the MAC address to the value of "old."

  For some hosted VMware products (such as Workstation and Server maybe player) there's a vmx ethernetX.checkMACAddress = "FALSE" setting that allows you to set any MAC address you want to. For more information, see http://sanbarrow.com/vmx/vmx-network-advanced.html.

• The virtual NETWORK card MAC address is editable in ESXi?

  Is it possible to put the address MAC of the virtual NETWORK adapter to a custom value instead of let the hypervisor generate the MAC address for each NETWORK adapter in each computer running under ESXi virtual? I know that this is possible in workstation, server, Fusion, etc.

• UCS mac address problem

  Hi all

  simple question...

  You may know if it is a bug of mac address learning with version 1.4.1?

  I have go a blade with a mix of palo and other cards, some vnic are pinned to link rising with trunk allowed vlan 501 on both sides. On the blades of the UCS, i've got ESX and ESXi. Service console is labelled VLAN 501 (depending on the configuration of the trunk switch UCS and uplink). Some blade had obtained these interface pinned on the UCS6100 A and another on B (with failover). The fact is that if I ping from outside UCS UCS (ESX) inside no learning of mac is performed on all infrastructure.

  I don't know problem is the UCS because if I erase the mac table UCS, nothing works... and all the works if I start doing a ping of the UCS. I also tried to put the switch uplink static mac (ESX service console) but was not helpful.

  I hope this isn't a 1.4.1 bug...

  TNX and tnx for help

  Dan

  Y at - it you using uplink groups pine or have a network of layer 2 disjoint by chance?

  Questions like these are ususally PIN-related groups / Disjoint L2 using the wrong link DR port for traffic entering.  When the traffic is generated from within the outgoing UCS, the MAC table is updated on the upstream switch which allows traffic to flow, until he gets older.

  If one of them is the case I suggest take you a look at the videos of Brad name video #6:

• VM mac address

  I migrated about 40 virtual machines from a virtual centre to the new virtual centre along the esxi host.

  now, I'm having a problem of duplicate MAC address. a few times my old vcenter takes a MAC address of a new vcenter.

  How this can happen and how to stop it.

  Another way rather than change the MAC address of the virtual machines attached with my new virtual centre.

  Thank you

  Hello

  When using multiple vCenter make servers you define unique ID on each vCenter. In this way, they don't use the same MAC address range.

  This will help only for VMS newly created however. I'm afraid you must change the Mac of your existing virtual machines or delete their network cards and create new ones.

• VMware device with 2 network cards claiming the same IP address with two MAC addresses

  Hello.

  I see messages intermittent my gateway network two MAC addresses associated with a virtual machine running on a 5.5 ESXi host for the same IP address.

  The virtual machine is a MiTel 3300 controller for a VOIP system. the system is configured with two IP addresses, one on the local network and another with a public IP address in the DMZ. In the network configuration of the 3300, I assigned the address LAN IP at 00: 0C: 29:30:B2:B2 and the DMZ IP at 00: 0C: 29:30:B2:BC (Mac for network devices presented by the ESXi host virtual machine).

  On the host, I configured a vSwitch with exclusive access to two physical network adapters on the host machine. The vSwitch is configured with two machine virtual port groups, LAN and DMZ, with access to the physical network interface cards. Tab grouping of groups vSwitch port NIC, I replaced the order of failover of the switch to activate an active NETWORK card only for the Group of LAN ports and the other card NETWORK only for the DMZ port group. (I don't know how the content of the column of networks is determined. Neither is correct for the traffic on the physical switch. If these are configurable, please advise and I'll change the settings). The relevant parameters of vSwitch, groups of ports and VM are distinguished below.

  On the virtual machine itself, through the VMWare host, I assigned 00: 0C: 29:30:B2:B2 for the Group of LAN ports and 00: 0C: 29:30:B2:BC to the DMZ group port (best I can tell, anyway, since the MAC address field annoyingly obscures the last two digits of the MAC address - break if I invert the mapping) (, but all seems OK).

  The goal here is to make sure that MACs of ports vSwitch the 3300 is listening and sending always correspond to the physical ports that are VLAN Tag by the physical switch to ensure the routing. Generally speaking, it seems that what is happening but, intermittently, we cross one-way calls that suggests a problem of routing between us and our SIP trunk provider; coinciding with these incidents, I get an email along the lines of "the security in the network device has detected a conflict of IP address with two or more devices. The period of INVESTIGATION "DMZ. DMZ. DMZ. DMZ' is claimed by the following clients with MAC addresses: ' 00: 0C: 29:30:B2:B2' ' 00: 0C: 29:30:B2:BC'. »

  I did something in the configuration that would lead to this kind of collision intermittent? Have a hacked together a way to do something that could be accomplished in a way that is simpler and more reliable?

  Thanks for any idea that you can offer.

  Kind regards

  J.

  

  

  

  I probably don't fully understand your configuration, but it seems that you are not interested in using the collection of NETWORK adapters in the virtual switch of the VM MiTel 3300.

  If it is correct, why not create two virtual switches, each with a group of port (LAN and DMZ) unique and with a separate connection of (vmnic2 and vmnic1)?

  In general, collection of NETWORK adapters may be used to share traffic between uplinks and ensure that if one of the uplinks connect fails, a virtual machine still has access to the network.

• Static MAC address starting not not by 00:50:56?

  Hello

  I have a quick question before I go to bed (so I have no time for some tests).

  I just found this article on the static of MAC addresses: VMware KB: defining a MAC address of a NETWORK card virtual

  The article says that "VMware uses a different YES to manually generated addresses: 00:50:56.»  But can I use the autogenerated, MAC address that starts with 00: 0c: 29 (and of course ensure that ESXi uses the same MAC address for an another VM)?

  Thank you

  Hello..

  Both are actually automatically generated... 00: 00c: 29 is generated by the host ESXi itself when not associated with an instance of vCenter. 00:50:56 is generated by vCenter if the ESXi host is attached to the phone.

  But can I use the autogenerated, MAC address that starts with 00: 0c: 29 (and of course ensure that ESXi uses the same MAC address for an another VM)?

  Yes...

• MAC address error when you use the New-VMHostNetworkAdapter cmdlet

  I try to use powercli to set up networks for a new 5.1 esxi.

  I get the error:

  The MAC address is not valid or is not in the range valid 00:50:56:00:00:00 - 00:50:56:3F:FF:FF

  The script I use:

  New-VMHostNetworkAdapter - vmhost $FQDNHostNaam - Portgroup Management Network - VirtualSwitch $VSwitch IP - $IPManagementNetwork - subnet $SubNetMask mask - ManagementTrafficEnabled: $true

  This creates the vSwitch, but runs into problems when calling to New-VMHostNetworkAdapter. It gives me the above error.

  Anyone?

  And did you try with go seek the portgroup first?

• assignment range static mac addresses

  Anyone know or knows where I can find what the mac address range is responsible for functions static mac end user for virtual machines?  There is a specific, cited in the 4.x documentation Beach, but the docs 5.x just say do not walk on the beaches of use reserved for vCenter Server, host network adapters physical, virtual cards, but says not what is Beach, reserved or allowed is, so I don't know what to avoid.  I opened a support ticket and asked the same question and I was told there is no specific void range defined for static assignment, and I have to look in my environment to see what was automatically generated for what could not be attributed.  Of course, this does not solve the potential problem of an address that I choose to be automatically generated by vcenter for a future new virtual machine.

  Also, does anyone know what virtual machine operations can cause the mac to change address?  I'm trying to determine whether it is necessary to assign a static address to a virtual machine that has a license associated with it, so I need to know what would be the probability of this change.  Support could not answer this question.

  Thanks to all in advance.

  Have you checked the http://pubs.vmware.com/vsphere-55/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-55-networking-guide.pdf 148 pages

• possible to retrieve the deleted vNIC MAC address

  Hello

  I deleted a vNIC and added a new vNIC in a troubleshooting session. The problem is that the server is picky about the MAC address due to licensing and now I would like to know if there is a way to recover the deleted vNIC mac address.

  Welcome to the communities.  I responded to this post in the AM, but it seems to have disappeared (back to maybe instant)

  1. identify the ESXi host the virtual machine in question feeds

  2. enable SSH on the host computer and the PuTTY as root

  3. navigate to the directory where the virtual machine is saved

  # cd/vmfs/volumes/path/to/vm
  Note: To determine the path your life of the virtual machine, you can watch the disc through the settings (vSphere Client), or run the following command:

  # vim - cmd vmsvc/getallvms | grep-i MyVMname

  4. to find the current and previous MAC addresses, run the following command:

  # cat./vmware*.log | grep MAC

  The output displays the date and time (in UTC) that each MAC address showed in the newspapers.

• Set the Mac address of vCloud VM

  Hello

  For a client, I need to clone a VM production regularly in vCloud for a test environment. The virtual machine must have an address identical Mac because of some outdated licenses. After cloning, it is there a way I can easily put the Mac address of the virtual machine to the original Mac address? Even if the virtual machines in the same environment of vCenter, but various groupings of ESXi hosts.

• The value of MAC address on deployment with the new virtual machine vm

  I am looking for a way to statically define the NIC MAC address on the deployment. I use a loop to create 24 copies of a model on several virtual machines and the need to put the MAC for DHCP addresses. I could make this work with esxi 3.5, but after the upgrade to vsphere, I have questions.

  Is - it possible or do I have after reloop with set-networkadapter? I try to avoid this if possible.

  So the next step to get just the device object

  . config.hardware.device (notice-EEG - VIObject "Template Name"). Where-Object {$_.deviceinfo.label - like "Network adapter 1"}

  That's what you're going to correct?
