Several networks management

In the environment that I support, I see there are two different vSwitches with management networks. Neither vmkernel is on a real management network (OOB), so I wonder what would be the advantage of having more than one? Both are connected to the same switch upstream.

I recently added a new host in the cluster, but only added 1 management network (it's on the same subnet as other guests), but when I added it to the cluster, I saw put HA cautioned that he could not reach the other management staff (2nd management network) networks on all hosts.

One advantage that I see if it's a problem with the particular subnet network type. Seems a bit pointless to me

Mark

This is mainly to avoid network isolation situation management in vSphere HA. as you can see, when you added a host more and configured only VMKernel for management, HA started that warns you that there is no redundant heartbeat network.

and even if it's on the same switches upstream, operating in the same subnet, it gives you link redundancy if there is a failure to VMNIC, a link, or level switch, you'll always have a way to reach the host to manage.

    Several networks of power line can exist simultaneously in the same electrical circuit?

    Thank you

    Yes, as long as you change the encryption keys can have simultaneous powerline of the networks.

    If two units with the encryption key "HomeplugAV" does not connect with two other units with the encryption key 'HomeplugAV2', but the two pairs will work independent of each other.

  • Several networks on Time Capsule

    Can someone explain to me why I have several networks? I went through the Airport utility, and I find myself with 5 networks. I understand the 2.4 GHz vs 5 GHz, but it seems to be confusing to some of my mottos (xBox, Wii, etc.). Thank you.

    You do not tell us how many airport routers, you might have, but it looks like you have 3 devices... unless you named the guest network the same as your main network.

    Recent versions of the airport are simultaneous dual-band, so they produce a signal Wireless 2.4 GHz and 5 GHz with the same network name.  So, it's 2 networks for a router.

    If you have a second airport, set up to extend or expand the network, then it too will be 2 networks with the same wireless network name. So, it's more than 2 networks for the second airport... for a total of 4 so far.

    Pourriez you have a version of a band unique AirPort Extreme or AirPort Express. So it's 1 over the network.  Or, if you have a recent version of the airport, the scan did not pick up the 'other' network at the time.

    Total... 5 networks.  Quite normal.

    Wireless devices choose the router with the signal the harder... at least in theory... then choose 2.4 GHz or 5 GHz according to their abilities and the distance to the airport.

    Of course, a feature which is 2.4 GHz only will connect to the 2.4 GHz network, then... in theory... it will choose the strongest signal 2.4 GHz of the nearest router.

    If a device can connect to 2.4 GHz or 5 GHz... It will be connected to 5 GHz, if it's in the same room or in immediate proximity to the router. But as signals of 5 GHz are much lower than 2.4 GHz signals, the same device will connect probably in 2.4 GHz if she moves a piece or two away from the router.

  • I have several networks that have shown up on my computer I have has not put there

    I have several networks appear on my network card that I did not put there.

    Hi Jim,.

    If they are wireless networks, you can simply pick up your neighbors with powerful transmitters router broadcasts and they do not mean that they have access to your system, but rather that you could theoretically have access to them if they are not correctly fixed.

    It would help greatly to be able to see what you see.

    Can you open the network map and take a screenshot and post on your SkyDrive with all access and then post a link here so we can see what you're talking about?  Here's help on how to do it: http://answers.microsoft.com/en-us/feedback/forum/feedback_other-na/how-to-insert-images-in-ms-answers/94a5cb36-a21f-4a6a-b266-611cf6c910c8.

  • Network management problem, computer laptop Windows 7 will not find other computers on any network, however all other computers on the network can access Windows 7 laptop.

    Basically, the issue I'm having is that my laptop does not connect to any other computer to access the actions or other files.  Other computers on the network can access my computer laptop shares and files without any problems.  Operating system is Windows 7 Home Premium x 64.

    What I tried:

    restarted
    uninstalling and reinstalling the files and printers, sharing maps and restart after completion
    all disabled firewall
    tried with IPv6 enabled and disabled without change, so it is currently enabled
    tried on a Wi - Fi and the differences are listed below in the section work (work is wireless)
    able to ping other comptuers
    access to other computers is permitted by other computers

    problem extends over several networks, IE I noticed it at home last night and the followed problem my laptop at work this morning.
    The problem is slightly different on the two sites.

    At home:
    I can see the other computers on the network, but I am unable to access it, even if I have permission, but other computers can access to my laptop.

    At work:
    Cannot even find other computers on the network but they can find and access my laptop.

    I have worked on this problem of non stop for several hours and did much more than what is said, but I am unable to remember everything.  I should have been taking notes: P

    Asked this question in the Windows 7 forum also because the problem was between windows 7 and Vista.

    Hello

    If it has started, you can try a system restore - an update "might" have caused the problem.

    1. try a system restore back to a point before that happened. And immediately thereafter enter
    Control Panel - Windows updates - top left settings and set it to download and informs you instead
    Automatic. Leave it until you are sure that everything is OK and then you can add them one at a time
    to troubleshoot BUT click right on and HIDE all the driver updates. Also stop at day of drivers like below
    and let this value - manually search for drivers when you think you need. (See how and why to)
    stop day of drivers below.)

    How to make a Vista system restore
    http://www.Vistax64.com/tutorials/76905-System-Restore-how.html

    To uninstall an update if you determine that there are problems - Panel - updated Windows - down left-
    Updates installed - uninstall

    I had completely forgotten the system restore!  While looking into the system restore, I found that when I moved into my new House and has cable Internet installed, the cable technology installed a program of comcast on my computer.  This caused me to not be able to connect with other computers.  After rolling back to install it before it works!   Thank you.

  • Default gateway and network management

    Hello

    After installing the initial (via a serial cable), we installed the default gateway on iSCSI network. IP address is defined for the management interface on the network of management as well. Now, we want to access different network management port.

    In fact it should really dg on iscsi network as there is not etc to another network for replication. So if I try to change the dg on GUI does not change me. Can I change the dg on cli or add new lines to the management network?

    Thank you

    With a dedicated management port, you have now two bridges 'by default'.   An iSCSI, one for network Mangement.  The iSCSI Gateway is strictly for iSCSI traffic.  All of the management features will use defined for management.

  • Cannot Wireless network Management Application

    We use Cisco Wireless LAN Controller 4400 for two years. Yesterday, we had a report that the Wireless does not work. We found that the problem is Cisco Wireless network Management Application does not start. If I try to start it, I get the network Wireless Application Management with Error 1067: the process terminated unexpectedly. I tried to clean boot, but that doesn't fix it. We have not changed anything on the server. Any suggestions?.

    It seems that the firmware is damaged or the compact flash (CF) is dying.

  • Please recommend network management software

    Hello!

    I need help to find a network management software that is compatible with our switches. I use a network with Cisco/Linksys managed switches:

    10xSLM2008,

    5xSRW208,

    2xSRW2008MP,

    1xSF 300-08

    I was hoping there is management software (not the thing webview/web browser), that could do these things (in order of preference):

    -connect to these SNMP (or similar) to show me a little statistics on each port on each switch, as well as the connectivity between these switches.

    -I would like to know which port what mac addresses and possibly the IP addresses of these.

    -Let me know what mac addresses uses more bandwidth

    -ban a mac address

    I'd be happy if someone could give me advice on what software to buy.

  • a restart of the network management will affect virtual on an IBM Blade?

    Hi all

    We are running an IBM Blade S with two blades HS22 located on ESX 4

    I would like to add a HS23 on ESXi 5 and then upgrade all three blades to the latest version of ESXi 5.

    I entered in the console HS23 and put up the name / networking details. When I go out, I get a message saying that the management network will be restarted.

    This restart will affect the virtual running on our existing blades? I have to arrest all of them first? If so it's a little bit of pain

    Network management only affects this network hosts to talk to other guests or to connect, but should not affect all guests of this host or any other host.
