Microsoft NLB question

Hello

Had a first go at NLB configuration. I have it configured in the same manner as my colleague did

physical boxes.

I have it configured as multicast and everything looks ok in the NETWORK Load Balancing Manager. Unlike with physical servers.

I can only connect to the cluster that is part of the same subnet. I can't ping from another subnet.

What gives? According to VMware should not require changes to the host.

I tried placing virtual machines on a host and different hosts. The results remain the same.

works only part of the same subnet.

see you soon

The key here is that the multicast MAC address is not captured by the routers in question.  That's why you can only ping locally in the same VLAN.  To resolve this problem, you need to create a static ARP entry on your 8.

Page 2 of NETWORK load balancing guide:

Some routers do not support the resolution of IP addresses unicast to multicast MAC addresses and they don't answer ARP. Thus, an administrator must add a static ARP entry in the router, mapping of the IP address of the cluster in its MAC address.

  • Microsoft NLB on a Port Channel

    Hi people,

    I read that static entry ARP is necessary to ensure the VIP created in Microsoft NLB cluster work properly with the network switch.

    http://KB.VMware.com/selfservice/microsites/search.do?cmd=displayKC & docType = kc & docTypeID = DT_KB_1_1 & externalId = 1006525

    However, each of the two VM in my NLB cluster is connected to a vDS configured with tagging VLAN. I have several VLANs on a channel of the VDS service port.

    Use of VLAN tagging/Port Channel make a difference in the procedure for setting up the static ARP entry?

    Thank you

    As long as your NLB nodes are on the same vlan, you should be fine.

  • Question of multicast and Microsoft NLB

    Hello

    I just set up our first server of Microsoft using multicast NLB cluster.

    The entry door of the VLAN is a 5540 Cisco and servers are connected on a pile of Cisco 3750.

    In order to let the ASA before executives for this multicast group I put static arp resolution in this cluster's multicast MAC address.

    No static MAC entry on our switches.

    All work purposes and multicast works but...

    (1) using the wireshark on our NLB nodes I found that frames are intended for machine unicast mac address. IF I ping from the ASA to the Cluster IP, ICMP is sent just for ALL NLB nodes.

    (2) all images are nodes NBL has the MAC address (physical) of unicast.

    (2) other hosts in the same VLAN do not receive all the emissions associated with this group (multicast works)

    (3) on our Cisco 3750 stack, multicast MAC address is not in the cam.

    Since only the NLB nodes receive this traffic, my question is:

    HOW the multicast can work only if the switch doesn't know anything about this group?

    Thank you

    Paolo

    Paolo,

    I really thought that you were using the IGMP option because of your statement:

    "(2) other hosts in the same VLAN do not receive all the emissions associated with this group (multicast works).

    Without the IGMP option, NETWORK load balancing uses a locally administered multicast MAC address with the format 03:BF:. Thus, this isn't an IANA-assingend (01-00-5E) multicast MAC address, IGMP Snooping can avoid flooding of these frameworks throughout the entire VLAN, which is the only way a switch can manage these frameworks. The recommendation to avoid/container this flood is the configuration of the static entries from MAC because the MAC of Cluster multicast (linking exclusively for the required ports). These static entries then also appear in the output of "show the mac address table.

    With the option IGMP, you can make use of the IGMP snooping to prevent flooding, so the static MAC entries are not required in this case and cluster multicast THAT MAC can be dynamically learned by IGMP snooping. It should then be listed in the output of 'show mac address-table multicast '.

    It can help to look at the files minidump against accidents with a debugger.

    Can you zip the minidump in the C:\Windows\Minidump folder files and (provide link) available via Windows Live SkyDrive or similar site?

    Hello.

    You can use the special function key mode which allows you to use the function keys without pressing the FN key. This can be changed _in BIOS_ (F2->-> Advanced tab-> System Configuration-> special function mode key in BIOS)

  • Microsoft license question for usage of Windows XP/7 with Parallels for Mac

    My mother bought an iMac two weeks ago (OSX/Lion). She plans to install Parallels and wants to use the Windows license of its old Windows XP machine that does more boot. Someone told me that Microsoft license requires that you use Windows 7 Professional or Enterprise - you cannot use Home Edition. Does anyone know what rule of Microsoft, for this for Windows 7 and Windows XP? I ask because it has Windows XP Professional now, I think, but could buy Windows 7 on both. Thanks for the help.

    If you have a commercial version of win, which is not currently installed on a PC, you can install it on any hardware/software that takes care of the victory. There is nothing in the MS Win license that specifies what type of device, it can be installed on. Unlike some other software manufacturers

  • Microsoft NLB and after vMotion network connections

    We have several hosts ESXi (4.0) one of them containing a virtual member of a NETWORK 8 Server Load Balancing cluster.

    When I migrate all servers to host containing the Member of NLB cluster virtual that I can no longer connect to one of the other 7 members. But the strange thing is I can reach any other machine on this host as well as not been transferred there recently (I don't know what triggers it)

    The migrated machine can reach any other machine not in the NLB cluster.

    The cluster is located in multicast. and is in the same subnet as the other servers.

  • Microsoft NLB on a virtual iSCSI SAN using computer

    Hello

    Is it possible to use the NLB network on a virtual computer that is connected to an iSCSI SAN?  I was under the impression that MSCS is not available, use an iSCSI device, but is NLB another form of consolidation?  I am unable to find a clear answer anywhere else.

    Any help would be appreciated.

    Yes its is possible, the storage has nothing to do with NLB, its pretty much traffic going to different hosts of network load balancing.

  • Microsoft RPC question

    Hello

    Anyone who has ever managed to make it work?

    We have a problem with our Exchange Server and which enables MAPI clients to connect to if only CPP is allowed. This problem arises not only with Exchange RPC, but RPC of the MS in general.

    Access lists allow all the ports that are required for sessions, and "established" is used accordingly.

    However, during the inhalation of vapours on the session, there is always an Exchange very short and insufficient packet TCP/EMP/DCERPC-to be more precise: only 5 to 50 packets are exchanged (as a regular session of the MS RPC takes more than 800)... It seems that the PIX is cutting packages.

    Ethereal shows that: "lack of DCERPC: call_id: 1 ctx_id: 0 status: unknown (0x00000005)"... and just before the EMP card ask for some UUID is made! ".

    Note that we have tried to make it work even without NAT!

    Someone at - it had a similar problem, or at least an idea of what seems to be the problem with that?

    Thank you

    Sasa

    Hello

    I looked into this before, our scenario was office workers home access to our Exchange through the PIX server, while they came from the external interface and the exchange server has been on the inside.

    After a lot of searching around, I found that using the established command on the PIX only works going from a high security below, interface or maybe it could have been more precisely inside the interface to the outside, I can't remember.

    I checked this with our Cisco representative at the time and he confirmed that it was true.

    Thank you

  • Implementation of Microsoft NLB on dvSwitch

    We would like to use windows network load balancing in windows 2008 R2 to load balance 2 web servers that are running on ESXi 4.1 using a dvSwitch.  Does anyone have experience with setting this up correctly using the multicast?  We have configured unicast now and when it is replaced by multicast it floods the network slows everything down for analysis.

    It's pretty simple.  You can do this with 1 NIC, but in 2008, it will give you an error at the launch of the NETWORK Load Balancing Manager, unless you have 2 network cards.  you just need to make some changes to switch to make it work.

  • Satellite L350D: License parameters & plant Microsoft Office Ready PC

    I'm about to restore a Satellite L350D factory settings. I know all wil programs and deleted files. I already have a backup copy of vista to al my files, but I'm worried about the office.

    I have a license of Microsoft Office Professional 2007, but an espcially for a Microsoft Office Ready PC (so not installation diskettes included). I don't remember how I activated on this laptop. When I do a factory reset can I use this license on satellite? Will there be a version of preinstalled office that I can activate with this license?

    Thanks in advance!

    Hi Linda

    As far as I know recovery image contains the Microsoft Office trial version and you can use it, I think, 60 days without activation. It can be activated if you have the correct activation code and you can enable it when you want.

    If you have this key should not be a problem for you, but unfortunately I can't say for sure because I use my own full version. What you can do is to contact the hotline of Microsoft and ask.

    What do we do Toshiba is to include this trial version in the recovery image, but everything else is Microsoft s question then maybe you should contact them first and ask for advice.
