  • 1.  Naming conventions of Adapters

    Posted Jan 25, 2013 04:46 PM

    In some screenshots, documentation, experience, I've seen Local Area Connection 2 instead of VMnet1 and vice versa.

    In some screenshots, documentation, experience, I've seen Local Area Connection 3 instead of VMnet8 and vice versa.

    When is "Local Area Connection" used instead of "VMnet" for the name of the adapter.

    I know that VMnet0 (bridge), VMnet1 (host), and VMnet8 (NAT) are also the names of the virtual switches, but how can we explain the discrepancy in the names of the virtual adapters (LAC vs VMn - Where the name of the adapter matches the name of the switch).

    Thanks.

    Are you talking about when using VMware Workstation? I have always seen the network connections say "Local Area Connection 1, 2, 3, etc" If there is only one adapter but it says Local Area Connection 2 and it doesnt let you change to "Local Area Connection" it is because the original physical network adapter is still in your machine as a non_present_device.

    If that is the issue, do the following:

    go to the command prompt and type the following:

    set devmgr_show_nonpresent_devices=1
    start devmgmt.msc

    Then you need to go to your device manager, click on view > Show Hidden Devices.

    Go to the network adapters tab and delete any half-visible adapters.

    I have never seen a network where "local area connection" is used instead of "VMnet" or vice versa. The only explanation I can give you is POSSIBLY if the documentation is going back and forth between the host machine's network connections and the VM's network connections within Workstation. Within the VM it would not show anything about VMNet8 or VMNet0. Only from the host computer will you see that.

    Does that make sense? You didn't give enough information to really know where to take this. HTH

    You completely misunderstood me.

    Look on p242 and p245:
    http://books.google.com/books?id=cFL91AZt01YC&pg=PA242&dq=vmnet+named+local+area+connection+2+simpson&hl=en&sa=X&ei=ZrsNUc-WLY2s0AHMsIGADw&ved=0CC0Q6AEwAA#v=onepage&q=vmnet%20named%20local%20area%20connection%202%20simpson&f=false

    I'm  talking about the names of the VIRTUAL ADAPTERS. This book says on p242  that they are called "Local Area Connection 2" and Local Area  Connection 3." There are screenshots to back this up on p245. HOWEVER,  I've always seen them in Windows at "VMnet Adpater for VMnet1" and "VMnet Adapter for VMnet8" (to mirror the names of the virtual switches named VMnet1 and VMnet8) NOT "Local Area Connection 2" and "Local Area Connection 3."

    The network names are created when you install the VMware product and depend on which product and/or version you use. If new network adapters (physical or virtual) are installed with defaults, Windows detects them and assigns names like "Local Area Connection n" where "n" will be increased for each newly detected adapter. It's also possible to create new network adapters with predefined names, that's when you see names like "VMnet Adapter for VMnet1".
