• using tools CLI to reconfigure the mac address static on VM?

  I've been poking around the CLI tools and perl scripts and do not see an easy way to reconfigure the address Mac to staticly assigned to a VM in the CLI.  Does anyone know useful tips to do this with the CLI?

  Yes/No, no VMware script canned exists today that help with this specific operation, but you can create your own script by using the vSphere API do and one of the operations that can be performed using the API.

  Here is a script that I wrote some time back and just changed to help manually assign a MAC address for a virtual machine given - vmNICManagement.pl

• 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

• Assign a static IP address via DHCP based on the Mac address of the virtual machine

  Hi all

  It is especially a feature request, as I'm sure that it is not currently possible to do what I want to do...

  I would like to be able to assign static IP addresses to VM without having to manually configure the network settings of the virtual machine directly. I want to be able to do it from the DHCP settings in the virtual network Editor.

  Most of the routers DHCP allow this. They give an IP address through DHCP based on the MAC address of the client. This means that the customer is concerned that he receives a regular IP DHCP address, but it is never change.

  DHCP is the default option for all OS this makes things much easier to manage, as IP addresses is assigned in the same way, in one place for all DHCP clients, regardless of the client operating system, and without having to manually keep track of which the IP is assigned to which customers etc..

  Also AFAIK at least for Ubuntu, you cannot assign a static IP address without having to also statically assign to the DNS server. It is only the IP address I need to be static, so I prefer not to have to worry about manually assign the DNS server.

  I can just kind of fudge making the really long DHCP lease duration, but the maximum is 99 days only, so finally addresses are going to change, that would mean a whole bunch of reconfiguration for VM services, etc..

  Does anyone know if the workstation 9 has this ability? I am currently on version 8, but I would probably upgrade this function only if she can do it.

  If there is no way to do what I want to directly through the virtual network Editor, can anyone recommend a way to do this, perhaps using Guest only network and then, by running a kind of services to the 3rd party NAT and DHCP on the host?

  Thank you

  Eugene

  There is no GUI option to get what you are looking for, but you can do it manually. Please take a look at Re: assign a static IP to guest with network adapter NAT Virt? where I posted an example.

• Script to set the static Mac address

  I have an Infrastructure virtual with about 200 vm with several vNIC and automatic Mac address. I need to assign static Mac for all NICs for and want to perform this operation with a powershell script and a csv input file. I have the entry csv file that looks like this: Vm, portgroup Mac Vm1 00:11:22:33 Vm1, pg1, pg2, 00:11:22:44 Vm2, pg1, 00:11:44:44 (I know the Mac above are not valid) can anyone help with the powershell code to automate the static configuration of mac?  Thanks in advance

  Hello, ITS.

  You should be able to use the following to achieve:

  ## import the info from the CSV$colNICInfo = Import-Csv c:\vmNICInfo.csv$colNICInfo | %{    $oSingleNICInfo = $_    ## get the VM, get its NetworkAdapters and for the one whose NetworkName matches that from the CSV, set its MAC address    Get-VM $oSingleNICInfo.VMName | Get-NetworkAdapter | ?{$_.NetworkName -eq $oSingleNICInfo.NetwkName} | Set-NetworkAdapter -MacAddress $oSingleNICInfo.MACAddr -Confirm:$false -WhatIf} ## end foreach-object
  

  A few things to note:

  • I left the '-WhatIf "parameter on the Set-NetworkAdapter portion, so that you can run this first (perhaps with a small sample of game in the CSV file) to check that things look like they will work.  Remove this parameter to set the MAC addresses
  • The code provides that the CSV of this format:
    MACAddr VMName, NetwkName,
    someVM, VLAN128, 00:50:56:00:00:0F
  • The cmdlet Set-NetworkAdapter requires the new MAC address in the range 00:50:56:00:00:00 - 00:50:56:3F:FF:FF.  It's not the range likely to use, VMware only a subset.  Seems to be a limitation of the cmdlet (probably intentional).

  Message edited by mattboren: added a note about removing "-WhatIf" to actually set the MAC addresses of the network adapters

• GS728TP management of IP through DHCP address praised even if static address is configured

  I have configured the switch to use the address static IP for using a management VLAN separate VLAN 123. The web gui is accessible through this IP address.

  Unknwon reason why switch leases an IP address on VLAN 1 via DHCP management. The web gui is also accessible through this IP address.

  The two VLAN has no common membership on any port of the switch. The only cable connected to the switch is the DHCP server on the VLAN 1

  Looking at the IP configuration to the web management interface, the value of the field default gateway is the gateway of the DHCP server address, but the IP address of the switch is static.

  Software version: 6.0.1.18

  Start the verson: 2.0.0.11

  Thanks for you suggestions. I solved it in other words.

  1 change managed VLAN id 1.

  2. change port VLAN 1 and connected, because by default the bridge field was empty. Introduced the setting correct and applied.

  3 changed back to the id of the VLAN managed original

  4. problem solved.

  I couldn't change to DHCP, was an error. But he did

• IP Phone Dot1x - database MAC addresses for the configuration of MAB

  Hi all

  I need to configure the MAB for IP phones on the ports that are active dot1x

  Can I keep the MAC address of IP phones elsewhere then on internal hosts of GBA?

  It is possible in the ad or something similar...?

  Kind regards

  Georges

  Hello

  You can use your AAA Watt database server racks until you set the mac addresses as users on these databases.

  Remember that the mac address and the password are the same and must match the format that it receives in the RADIUS access request.

  Example: If the AAA client (switch) sends the mac address of the format xxxxxxxxxxxx, and then you create the user with this format.

  If she sends in the xxxx.xxxx.xxxx format, then you must create the user in this way.

  Usually, he sends in the format xxxxxxxxxxxx, but worht to ensure.

  HTH,

• 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...

• Make Unique MAC addresses for cloned library configurations

  I have a Setup / configuration library that has 2 models vm included.  How can I ensure that when users clone the configuration of the library of their workspace, it will give multiple users various MAC addresses for the NICs on those virtual machines?  Now when users clone the config from the library to the workspace, it errors out after 1 because they keep receiving the same Mac.

  The IP address and MAC to a library configuration does not change when you clone them to a workspace that they use network models.  Only a regular configuration will do it.

• Mac virtual machine Configuration address

  How can I keep my configurations to generate new MAC addresses?

  MAC change invalidates my network in my VM settings, rendering it useless.

  More specifically,.

  -my computer virtual model is configured with the MAC address. ("Perform the customization" is unchecked)

  -J' I create a new "Configuration", adding my VM to my model.

  -Check the virtual machine that is now attached to my new "Configuration".

  -He added a new different NETWORK card with a MAC address.

  I thought the point of Lab Manager to be able to deploy the same VM several times in a network closed so I don't have to go and reconfigure my VM whenever I have deploy them.

  I missed a setting?

  Thank you!

  Creating a configuration of a model always changes the mac address.

  However, a configuration of another configuration cloning does NOT change the mac address, nor made a check in library or discover.

  What you really want is to assume that the model is a temporary object that is complete with the exception of what anyone dependent on a network, and then create your first configuration.   Configure this virtual machine as desired with software specific mac/ip you want, and then check your vm finalized in the library.  You need several copies of the same thing, so you check out of the library.

• MAC address script static or dynamic?

  Hello

  Please forgive me for my total noob question.  I'm sure that there is a good quick word I can use to understand which machines have a static mac and which have been assigned a dynamic mac... Can someone tell me please in the right direction?

  Thanks in advance!

  Of course, this information is stored in the object VirtualEthernetCard .

  The addressType in this object property can be 3 types of values:

  *) Manual: statically assigned MAC address

  *) Generated: automatically generated MAC address

  *) Affected: MAC address assigned by VirtualCenter

  The following script will run through all your guests and list for all cards of the type of MAC address

  
  $report = @()

• Filtering addresses MAC wireless network configuration error

  Hello

  I got my printer (Deskjet 3510) some time ago and set up no problem for wireless printing. Yesterday, all of a sudden, it stopped connecting to the network. I have reset the wireless settings and ran the CD to re-establish the link. Now, when I get to all wireless to the top of the page it says «Filter error WiFi - hardware MAC address has been filtered out and do not < SSID >...» »

  I checked my router settings 2-wire AT & T (U-Verse) and address filtering MAC is not enabled. I did a scan and he picked up a bunch of MAC address and put them in the "Authorized" zone Is the MAC address of the printer. I tried enabling MAC address filtering, and it still does not connect. If at the moment I have the printer working via USB, MAC address filtering on the router go out but I still get the error. I have not changed the position of the printer or router as he worked. Not aware of any update of applied software.

  Any help would be greatly appreciated.

  The Mac address filtering error is one that is given for a multitude of errors, it is not very useful in this way.

  On the front of the printer, press the wireless button and go wireless by default.  Restart your router by pulling its plug momentarily, and then try again

• Configure filtering of MAC address on WRT54G - nothing links

  I created MAC address filtering on the wireless router.  5 MAC addresses added to the ALLOWED list, by selecting from the available devices.   Saved the changes.  Now, none of the machines can connect to the access point.  This includes the PC that I use to connect and administer the access point.  I plugged the network cable directly to my PC to manage the router/access point.  Still not able to connect.  That's happened?  How can I go and turn off this nonsense.  I know that MAC filtering is moot wrt efficiency, but I decide to try it.

  Reset the router back to the default values. Reconfigure from scratch.

  You're almost there, the MAC address must be specified as a string, enclose it.

  New machine virtual- - name VMSTORE23 - $vmhost $esxhost - $datastore - DiskMB 20000 - MemoryMB 2048 Datastore - NumCpu 2 - NetworkName "Vlan 6 Machine virtual network | Get-NetworkAdapter | Set-NetworkAdapter -Type Vmxnet3 -MacAddress "00:50:56:bb:00:2 b" - confirm: $false

  I added the - confirm the setting, as it will not request the change.

• BEFSR81 v3 MAC address filtering

  I have a simple network configuration with wired computers connected to the router and the router connected to the modem.

  My goal is to associate the IPs assigned to MACs. So if I have 4 (A, B, C, D) computers connected to the router, it assigned a specific IP address. If someone disconnected a computer to replace it with their own, the router would recognize the MAC change and could not allow the connection.

  I know that the router can filter certain IP or Mac addresses from the internet, but some evil doer who simply unplug the computer to plug its own would still have access to the local network. That and I have no way of knowing what would MAC the author.

  So far, I have configured my computer to request a static IP (192.168.1.2-5) and the DHCP Server give the rest (6 to 254). Then the IP filter is on the DHCP range to block those from the internet.

  But as I said, I need these completely blocked IPs. Also. If a user connects to a computer windows laptop and guess the static IP address, then the router fortunately would give him access to everything...

  Sorry, I know it's confusing. Bottom line is I have to let only specific Mac to connect to the network. Or SOME form of protection for the cable networks... Super sticky ethernet cables is not an option, although it would solve the problem.

  Cannot do this with the BEFSR81 and it is not a matter of how it is recent - the firmware just does not support, does support an address IP or MAC, some of them not allowing not blocking.  I think that it has been designed as a primitive, rather than a security measure parental control.

  With DHCP servers better (like those of most of the firewall) than the BEFSR81 has, you can configure DHCP to "static maps" so that the lease of the intellectual property will be distributed based on the MAC address, and which would you allow to adjust things until only the DHCP leases to some MAC addresses issue.

  Despite this, MAC addresses can be manually changed and spoofed, such as IP addresses, so neither is really a good measure of security.

  You have to ask in the BEFSR81 firewall features, which, instead, is simply a router.

  In the grand scheme of things, because the MAC and IP addresses can be spoofed, if someone can get physical access to your network, you are pretty well watered unless the traffic is encrypted.
