• Not able to ping from EXSI and NEXUS of EXSI HOST default gateway

  Hello

  In my topology I use 2960 switch thanks to which are connected the my fabric for interconnection and the NEXUS, I am able to ping ESXI switch but when I ping the blade and the Nexus of ESXI HOST, is not ping and also not able to ping default gateway through EXSI.

  I use X Vlan for all devices.

  Please suggest...

  The first thing is to make sure the VLAN ESX is defined from the NETWORK adapter to the router. the 5K the routing in this case? Also the fabric of interconnections and the pool mgmt of blade must be on the same VLAN / subnet. It seems that the FIM is on

  .7/25 and blade MMIC in sur.100/25. They must be on the same subnet. for ESX, please ensure that your vNIC has the VLAN correct represented and that his license.

  Hope this helps,

• ESXi hosts SBS 2011, clients lose network via VPN

  Greetings,

  We have an ESXi Server (in a lab environment) who perform a SBS 2011 and a Windows 2003 (Terminal Server).

  We have two locations, connected via a VPN IPSec (2 boxes of ClearOS).

  The ESXi host is located in building r. customers in the construction of an experience no problem at all.

  Customers in the building B often lose connectivity to network share. We also failed when copying data. Do not forget that the servers are located in the building and issues affecting only users in the B building.

  We noticed the event ID 2012 on the VM SBS 2011 event viewer.

  The two buildings are connected to a cable broadband 10 mb / 1 mb ISP.

  NOD32 Antivirus is installed on the two virtual machines

  Any help would be appreciated!

  Thank you

  Hello

  There are a few things to look out for more such links. The following steps were made on W2K and W2K3, so that they are still applicable for you.

  (1) is the VPN capable to manage the packet being sent by site B MTU size, sometimes the MTU on VPN size must be less than the default value of 1500 set LAN. You can check this scathing your server with a command like

  ping f-l 1500

  If you get a message like "packet needs to be fragmented but DF parameter.

  You will need to reduce the size of the MTU TCP/IP in the client registry. Try to ping the server with a size of 500 bytes and see how it goes.

  (2) setting the server TCP/IP stack

  In the registry HKLM \SYSTEM\CurrentControlSet\Services\Tcpip\Parameters, create or modify value DWORD of TcpMaxDataRetransmissions. By default, it is set to 5, but I recommend double this value to 10. The TcpMaxDataRetransmissions value is the number of retransmissions of TCP of a data segment without acknowledgement of receipt on an existing connection. TCP retransmits data segments until they are acknowledged or until the expiry of this value. Basically, when a client does not meet a package from the server, the server will attempt to retransmit the packet until TcpMaxDataRetransmissions many times. By increasing this value, you give the customer more time to answer on the server, which will help improve the flaky connections or connections with latency or higher than normal packet loss.

  HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\KeepAliveInterval and HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\KeepAliveTime.

  Both entered DWORD.
  KeepAliveInterval determines the interval between retransmissions keep until a response is received. If a response is received, the delay until the next keep alive transmission is again controlled by the value of KeepAliveTime.
  The connection will be broken once the number of retransmissions specified by TcpMaxDataRetransmissions is remained. KeepAliveInterval is set by default at 1000, which is one second.
  KeepAliveTime controls how many times TCP attempts to verify that an idle connection is still intact by sending a living package of the Dungeon. If the remote system is still reachable and running, he will acknowledge receipt of the living transmission to keep. KeepAliveTime is set by default to 7 200 000, or 2 hours.

  I hope this helps.

• Clones related single default ESXi host

  Hi all

  I'm in the middle of a CEP of view and I am messing around with linked Clones. I don't know if this is just how the composer is designed, but when I made 3 VM and they all default to one of my ESXi host in my 6box cluster (each box has 4 GB of RAM), it seems that the linked clones want stay with replica here. It stinks because we wanted to be able to compose 20 + VMS to a laboratory for testing. I have a host in my cluster that doesn't even have a virtual machine running on it... In any case the advice/help/advice is greatly appreciated

  Thank you all

  Yes, right click on a virtual machine, select Migrate-> select change host-> select another host in the cluster even-> select a priority and finish.

  Alternatively, you can drag and drop a receiving vm to another esx host in the same cluster.

• Losing Internet connection because of the default gateway is not available.

  I keep losing internet connection and when I run the troubleshooter, it comes up saying "the default gateway is not available". I have an HP with Intel dv6985se. I was advised to do the following:
  I had the same problems of chance which I fixed it by simple disabling 'SLEEP ON DISCONNECT' SideScalng disconnect

  1 Access Device Manager (Control Panel > system and security > system > Device Manager)
  2. expand the network adapters
  3. Select the adapter that you are using (if more than 1 Repeat step 4 to 8 for each adapter)
  4. right click and select Properties
  5 click Advanced
  6. If you have installed Nvidia Ethernet configuration click the button
  7. scroll to the bottom of the list and disable the device sleep on disconnection and receive Side Scaling
  8. save the settings

  I appreciate this help info but none of this applies to my computer has. In my device under 'Network adapters' Manager, I do not have Nvidia, Asus and AMD, which is listed under my network cards is "Intel Wireless WiFi Link 4965AGN" and "Realtek RTL8101E Family PCI - E Fast Ethernet NIC (NDIS 6.20)".

  The help that I've provided says disabling "Sleep on Disconnect" and "Receive Side Scaling"... or those who are in one of my "adapter properties tab advanced options" for both my Intel and Realtek... no where does say anything about sleep on disconnect or side scaling.

  I was online with HP cat many times and Ive tried the options they have provided that is basically what I've found here but nothing has worked so far! My computer is 1 1/2 old and is preinstalled with Vista 64-bit. Recently, I have completely restored my computer with Windows 7 64 bit, and ever since then, I can't download anything or talk to HP or any kind of help because I lose the connection. Could someone please help me solve this problem... to be frank and honest he pisses me off beyond words that I never had this problem when I'm on Vista!

  I don't know what else I can provide to better help me to solve this problem, but if anyone would like more information on what programs etc, my computer has let me know and I will provide the information. Below, I'm pasting the info I received through my history of troubleshooting like a Notepad of paper Network Diagnostic and Route.Print document.

  If the error does not recur in safe mode then there is probably a startup item or service causes the error. Follow the steps on the following link to locate the item or service responsible for the error:

• Nested Hyper-V VM cannot ping the default gateway

  Hello

  At first, I have to say that I don't consider myself an expert produced a VMware.

  I've been struggling with my test environment nested for a while and finally decided to get help (I hope) of pros.

  Environment looks like this:

  • Physical VMware ESXi 5.1.0 ("Promiscuous" mode enabled for the vSwitch)
    • Couple of virtual machines, one of them being Hyper-V (Windows Server 2012 R2) server that is configured for nested virtualization - 10.106.5.27
      • On the Hyper-V server, I have a VM in Windows Server 2012 R2 - 10.106.5.28

  Hyper-V server has a NETWORK card and full network connectivity (internal and external: Internet) and in the Hyper-V Manager, a virtual switch is configured in external mode.

  VM is connected to this virtual switch via a virtual network adapter. It has public static IP assigned with mask subnet, default gateway, and DNS even as a Hyper-V host. I ping times by IP and DNS name of the host of VM and vice versa. I cannot ping other resources of the virtual machine as the default gateway and DNS ("request timed") servers out. State of the network in the network and sharing Center is VM:

  • unidentified network
  • Public network
  • type of access: no internet access

  When I run the tool for troubleshooting problems on VM, he says "the default gateway is not available". As I said I can not ping.

  I think that all my connectivity problems are caused by the unavailability of the gateway by default on the virtual machine, but I have no idea how to solve this problem. When you change the settings of the VM card from static to DHCP I can't even ping on the Hyper-V host.

  All servers are joined to the same domain (VM has been migrated to ESXi, so he joined to the domain before, but I can't connect to using domain accounts, probably due to network issue).

  I hope I described the problem enough, but please let me know if you need more information.

  Try to activate forged passes also on the vSphere vSwitch as you do for the Promiscuous Mode.

• ESXi host goes to the State and the virtual machine does not restart on other host does not

  Hi all

  I'm looking for a solution, in which case the host goes to the State and the virtual machine on it does not restart on a different host (they'll just gray) does not not what could be the problem here and how to fix it

  later when the failed host returns upward machines either go to motor off the coast of the State, or they show that under tension

  While the host is down or not responding do not I am able to ping the host ESXi (5.5) and able to ping the default gateway and the DNS servers of the host itself

  Yes AF, the answer to all these questions is Yes, it is a HA and DRS cluster active, I tried restarting mgmt service, we use a shared storage (storage iSCSI HP 3PAR and left hand)

• Cannot set the default gateway in ESXi6.0.0 Update 1

  Hi team,

  I'm recently set up esxi 6.0.0 update1a on a Dell Poweredge M915 server. When I set up the IP address and gateway DCUI I get error below, I do not know why.

  Enable management network errors:

  Default gateway setting has not failed to set the gateway address vmkernel to X.X.X.X there is no VMkernel interfaces on the same network with this IP address.

  Help, please.

  Try to set the mask of the host to 24 (255.255.255.0), then network IP and the IP of the gateway management will be on the same network.

• Adding secondary management NIC to ESXi host

  Hello

  We currently have a customer demand to add secondary management NIC to the ESXi servers ourselves and the client can connect to hosts if vCenter becomes unavailable.

  Is someone can confirm if it is feasible or will host blend and become inaccessible? Sorry if this is an obvious answer, it's just that I have never seen configuration with management NIC

  Thanks in advance.

  We currently have a customer demand to add secondary management NIC to the ESXi servers ourselves and the client can connect to hosts if vCenter becomes unavailable.

  Can clarify you what exactly you mean by that? A single management interface are accessible by some many different clients, as long as it is accessible. Are there limits where the client manages the ESXi host from an internal network and you need to access externally via public IP, another for networking?

  In this case your would create a management interface 2nd vmkernel on the external network and to face together the default route of the external gateway routing and insert static routes for the internal network using the internal network gateway. So basically the same thing you would do to any IP multi-hosted system.

• Linux comments can contact other guests but not the default gateway.

  Hello.

  I have a 5.1 ESXi. client 5 running serverhost. The network works fine for 4 guests. But when I try to add a new host Linux I can communicate only with other comments operating systems and not the default gateway.

  I checked all the steps in this troubleshooting guide:http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1003893 but I still have the same issues.

  On the host, we have 2 NIC, I tried both NICs and nothing works for this new guest, while the NETWORK adapter do not work for the other hosts.

  How can I solve this problem? Any help is appreciated!

  Welcome to the community,

  can I assume that you are maily talk guests (VMs) and not all the other guests (ESXi)?

  In any case, did you double check the client network configuration to verify that there no fault of typo in the example subnet mask?

  What type of physical switch are you using? Some switches come with port security, which limits the number of MAC addresses that can register on a single port.

• Default gateway on different VMkernal

  Hello

  We have one physical server with 2 nic and Enterprise 5.1 ESXi version current cards. Now, we need to configure a network card for the internal network (internal) and the other for the DMZ on firewall (DMZ). The DMZ network adapter will be connected directly on the DMZ Firewall interface and internal nic will be linked on the internal switch. I created vSwitch0 Standard with VMkernal for nic internal with internal subnet and gateway. Another vSwitch1 is created with VMkernal for the NIC with IP DMZ DMZ. But the question is that the default gateway is for the internal entry door. I need to know how we can assign separate DMZ vSwitch VMkernal default gateway.

  Please notify.

  Thank you

  I think you misunderstand the use of management network (VMKernel port group). The management network is used by the host (ESXi) to connect to the network. There is no need of a group of VMKernel ports on each vSwitch. Just add a new vSwitch with a group of ports of Virtual Machine for the DMZ network, that's all. All network configuration (IP address, network mask, gateway) must be configured on the virtual machine.

• ESXi host does not synchronize with NTP - causes HA config failures?

  Hello

  We are currently implementing some Cisco UCS systems. We using blades Cisco UCS B200 M1 (x 5670, 48 GB of RAM)

  Everything seems to work fine except these little things, which seems to be related.

  1 NTP synchronization is not happenning, or happening very slowly.

  2. a 10 cluster host, when it is configured for HA, has many guests who fail to be configured for HA (for example we had only 2 guests get properly configured for HA out of 10).

  Initially, I thought REP 1 and 2 were not related, but then I remember reading somewhere that the ESXi host must have simultaneously for HA to work.

  On question No. 1:

  10 guests have a difference of 5-6 minutes between them. Curiously, the first hosts that are connected to a HA cluster, if their duration is similar, they wil work.

  But others are more than 1 to 2 minutes off, they will fail. Our NTP is configured on 2 internal NTP servers, which syncs with the outside world - the 2

  NTP servers are:

  The default gateway of each ESXi

  The network Core switch

  We know that the NTP servers work correctly because our advertising is synchronized with them and we checked on our domain controller local time main external time source.

  Debug information

  Output of /etc/ntp.conf

  ~ # cat /etc/ntp.conf
  restrict default kod nomodify notrap nopeer
  restrict the 127.0.0.1
  Server 10.*
  Server 10.*
  driftfile /etc/ntp.drift

  Everything has been configured through the GUI, I show the output of ntp.conf for confirmation.

  We tried to restart the hosts (without success).

  Everyone knows what we can do to solve this?

  Thank you

  You tried to restart NTP.

• Allowing access to ESXi host to other subnets

  Hi all

  I use the free version of ESXi and it is in course running on the network. 10.32.125.x I noticed that if I try to connect to the host via the Client vSphere from another network, such as 10.32.126.x, I can't.  I can't ping or SSH host either form the 10.32.126.x network.  All right if I'm on the 10.32.125.x network, which is the same network that the server is running on (10.32.125.63 is the IP host address).  I can access services on thin virtual machines from other networks, just not the ESXi host itself.

  Any ideas of how I can allow access of networks other than that on which lives on ESXi?

  Thank you

  Hello

  You try to access your client vSphere ESXi host, make sure that your DNS and default gateway are defined and correct? Is your default gateway on the ESXi host on your router?
