• Unable to activate the management network...

  I'm new and VMWare VSphere and I tried to connect to a server with VSphere ESXi 4 but I kept getting hung up on the screen «Download tools to manage this host From...» ». I disabled the management network, hoping it would allow me to bypass the connection and enter the server, but he clung to the option 'download... Tools '. "the screen again, but this time with a 0.0.0.0 IP. I tried to activate the network again, but now I get the error, "Management Network Interface was not found". I don't know what this means and I'm having a devil of a time to discover.

  Hello

  The screen you see (yellow screen with 'download... Tools) is the screen of the ESXi server. to manage the ESXi server and the virtual machines installed on it, you need to connect to a windows box, navigate to the IP address (using a web browser) indicated on the yellow screen and then download the VSphere client tool, of course ensure your network working properly. The VSphere client tool will then connect to the ESXi and manage accordingl.

  Hope this helps

• ESXi 5.5 - unable to connect to the management network

  I've been using ESXi for v3.  I have a small cluster of HP DL360 G5 where I was using ESXi 5.1 update 1.  I brought a new DL 360 G5 into the mix and decided to install 5.5.  After the installation, I'm going to set up the management network as usual and even after a reboot, I'm unable to access the site via http or the vSphere client.  For help, I installed the version of HP with CIM providers and I installed the stock VMware 5.5 with current pilot Rollup and they all exhibit the same behavior.  It starts fine, but I can't connect to the management network.  Curiously, however, they address IP does not respond to a ping.  I installed the 5.1 update 1 on the same server and it works fine.  Does anyone have an idea on what's going on?  Are there recommended troubleshooting steps?  It's strange to me because the ESXi has always been very reliable on HPs.

  Thank you - Greg

  Hi Greg,.

  Welcome to the community of VMware,

  To begin with, the latest version of ESXi, VMware supports the Proliant DL360 G5 has ESXi 5.0 U3.

• Second NETWORK card takes over the management network

  I have a lab of dev ESXI 5.5 on a Dell PowerEdge 2950 with a dual port GbE NIC (Broadcom NetXtreme II BCM5708).

  My basic configuration was a port of configured NIC (vmnic0) with a switch (vSwitch0) Standard.  vSwitch0 was a group of Virtual Machine (for VMS) ports and a VMkernel Port (for the management network).  Everything worked well at this point.

  When I try to configure the second NIC (vmnic1) to a different network switch port and different to connect to iSCSI, network range vmnic1 took over the management network even if it does not show as being the management network.  After that, I'm more able to connect or ping the IP of vmnic0.

  When you configure the vmnic1, I added connection Type of VMkernel.  I did not choose to use the port for traffic management group.

  When I look at the console and choose to configure the management network I see only being vmnic0selected network adapter.

  Am I misunderstood the management network configuration?  If not, does anyone have a suggestion on what may be wrong or how I can diagnose?

  Thank you for your comments!

  I think I knew what was going on.

  I had my VMkernel for networking (192.168.2.0/24) in a different subnet to the VMkernel for iscsi link port (192.168.1.0/24).  The problem was due to the existence of a network trace unidirectional from 192.168.1.0/24 to 192.168.2.0/24 (but not in the opposite direction). As stated in the post of the blog below and elsewhere, if there are two VMkernels in networks with a direct route, the esxi host will be simply choose one of the VMkernels to act as the management network (no matter if only one of the VMkernels has active network management).

  I thought my networks did not have a direct route because of the impossibility (192.168.2.0/24) management network to communicate with the network of liaison port iscsi (192.168.1.0/24) but because the 192.168.1.0/24 network may route to 192.168.2.0/24, he made the two viable VMKernels to act as the point of view of the host management networks.

  After that I moved the post iscsi binding to a switch with no network route, my problem has been resolved.

  Re-reading the following is a blog post that helped me to understand my problem.

  Thanks to those who took the time to review and respond to my problem.

• Is it possible to stop the conversion through the management network?

  Our management 172.16.0.0/16 network and our production network 10.0.0.0/8

  When we try to make the P2V conversion, all traffic through the firewall that we use for routing between 2 networks, that really is not set up to deal with a lot of traffic and that is what is extremely slow conversion.

  Is it possible to get the converter to push this traffic through the network of production instead?

  the system is 3 ESXi hosts grouped in vcenter 5.5.  Is the storage on a San

  ESX expose NFC (network file copy) as a service that uses a converter to perform conversions and NFC uses the management network. As far as I know, it cannot be changed.

  There is one exception, if--if you do Linux P2V, cloning goes through the network of the virtual machine and you will not have this problem.

  I think you may have a more general with this configuration problem, as the NFC is used not only by the converter (for example, SRM, VMotion, etc...). See this: why vMotion uses the management rather than the network vMotion network?-frankdenneman.nl for something completely different, but which may sometimes cause a problem with this Setup.

• Circuits/server on the same subnet as the management network

  I'm having a difficult time for a virtual PC running on my server ESXi.  The IP address is on the same subnet as the management network statically assigned IP address.  The switch that is connected to the server port is trunking.  My question is, can devices on the same subnet as the management network?  If so, how do access you?  You have to create a new vSwitch for this?  Any help would be appreciated.  Thank you.

  Your portgroup for CUP7 is set to VLAN 1, while your progroup vmkernel port has no encapsulation VLAN defined.  Just change the portgroup to CUP7 to have no value in the box VLAN (its under settings for the portgroup).

• Have problems with the IPSec VPN Client and several target networks

  I use an ASA 5520 8.2 (4) running.

  My goal is to get a VPN client to access more than one network within the network, for example, I need VPN client IPSec and power establish tcp connections on servers to 192.168.210.x and 10.21.9.x and 10.21.3.x

  Can anyone help me please with this problem? There could be a bunch of superfluous things here, and if you could show me, too, I'd be very happy. If you need more information on the config, I'll be happy to provide.

  Hello Kenneth,

  Based on the appliance's routing table, I can see the following

  C 10.21.9.0 255.255.255.0 is directly connected, DeviceManagement

  C 10.21.3.0 255.255.255.0 is directly connected, servers

  C 192.168.210.0 255.255.255.0 is directly connected to the inside

  And you try to connect to the 3 of them.

  Politics of Split tunnel is very good, the VPN configuration is fine

  The problem is here

• Allow Cisco VPN Client through the firewall?

  Hello

  How can I allow a cisco VPN client work from the inside of our network to an external IP address?

  We have customers who wish to make use of their Cisco VPN Client companies but our ASA blocks I think?

  Also (sorry to ask) a friend in South America is having the same problem but I am not hink they use Cisco, is there a default port used by the client to Cisco? then I can send this info?

  Thank you

  Generally, the ASA will allow the IPSEC from the inside to outside traffic. This is when you want it came outside and connect to you - this is where it gets creative. You restrict outgoing traffic at all? You deny all ip/tcp/udp outgoing?

  But may depend on if the remote end is compaitable NAT - T, and if they have configured. Another question would be how they allow VPN traffic go?

• PIX - ASA, allow RA VPN clients to access servers at remote sites

  Whenever I restart my computer, I get a popup window asking me to deny/allow incoming network connections to python.app. I checked my firewall settings and they are configured to allow incoming network connections. How can I fix so I did not have these messages?

  Create a new account and start in this account. If the problem persists, it may be another application is triggering demand or maybe it's that the firewall application is causing the problem. Function where and how you use your mac OS firewall may not be necessary.

• 2 groups of ESXi allow the same network for vmotion?

  I have 2 groups in the same data center.  The first is a cluster of ESXi 4.1 of 8 guests and appx 120 VM.  The other is a cluster of ESXi 4.1 6 hosts and appx 100 VM.

  On the servers in the cluster first, I mgmt interfaces on vlan 5 and vmotion interfaces on vlan 6 (different VLAN = recommended).  On the servers in the cluster 2, they were Setup with the interfaces of mgmt and vmotion interfaces as well on the vlan 7.  I want to correct this by moving vmotion to one vlan different.

  Is there a reason that I should not use vlan 6 for vmotion for both groups?  Or would it be better to have each cluster on its own vmotion vlan?

  Thank you.

  Yes. We have 9 clusters in two different vCenter, and they all use the same VLAN for vMotion.

  There is no route to the address pool of vpn. Maybe that's the problem? I don't know than that used to work before we went to 8.4.

  Check if the firewall is enabled on your host from the client ravpn and blocking your pings.
