• Create separate isolated networks & fill with VM?

  I remember in a previous version of VMware workstation, you might create separate networks (false) and fill with the virtual computer.  Of course the VM could not see outside that network, but for testing purposes, it was great.

  I suspect a similar functionality is present in ESXi 5, but for the life of me I can't understand it.  If someone can point me in the right direction, I would appreciate it.

  Of course, it will work for a single subnet if you add this uplink directly connected to the vSwitch.

  If you need to move beyond that subnet, you will need a virtual router to act as a gateway.

• Questions of ESXi 5.1 ISCSI--> cannot establish a network connection (continued)

  Hello world

  I had a problem there not too long ago (thread link below) where my ESXi hosts could not establish a connection with an IBM DS3500 on start up and "rescan", however their connectivity worked correctly without any problem after commissioning and when a "rescan" finished. We determined that the most likely cause was the unit IBM itself. However, I wasn't completely satisfied.

  In order to deepen the question and dismiss my guests being the problem, I created a unit ISCSI myself with two new hosts of ESXi 5.1 (version 1157734).

  ESXi signals that it cannot connect to the initiator ISCSI (network error) - but it can run virtual machines and browse data stores?

  The configuration is the following:

  Test environment:

  2 x ESXi 1157734 hosts

  1 x server Freenas ISCSI (ZFS R10)

  At the start of my ESXi hosts in the test environment, download the same error as our production environment. They also put on the same error message (in the event log) when I "rescan" map of the ISCSI software. However, once the scan is finished, I can't see any error message and everything continues as it should (Round robin, active active). I can get a brilliant flow also. It's as if the errors are almost... false positives?

  Example of the error message (test environment):

  Connection to the iSCSI target

  IQN.2011 - 03.org.example.istgt:iscsi on vmhba35

  @ vmk2 has failed. The iSCSI initiator couldn't

  establish a network connection to the target.

  ESXi hosts are configured as follows:

  Test environment:

  • (ESXi hosts) Two network cards for ISCSI, one for VM traffic
    • NIC1: 10.20.20.2/24, NIC2: 10.30.30.2/24
  • (Freenas) Two network cards installed on the ISCSI device (dedicated to ISCSI traffic)
    • NIC1: 10.20.20.1/24, NIC2: 10.30.30.1/24
  • ESXi is set to round robin, which works properly (I can max on both ports at the same time)
  • Two VMKs are related to the ISCSI Software initiator and defined to dynamically discover the two ISCSI addresses
  • Unity of ISCSI and the hosts are not on the VLAN, the switch is dedicated to ISCSI traffic (However in the production, the two networks are separated by VLAN.) I removed the in the test environment to simplify everything)
  • The vSwitches (who hold a single VMK for ISCSI) are fixed:
    • "Promiscuous" mode: reject
    • Change of MAC address: accept
    • Forged passes: accept
    • The traffic shaping: disabled
    • No NIC teaming (obviously)
    • Each VMK inherits the settings of these

  Quick points:

  • My hosts use VMware approved NIC in my test environment. My production environment runs on full VMware hardware approved
  • Can I use ping of vmk join each each VMK ISCSI initiator
  • I can use the nc-z target_ip 3260 command to check connectivity to the port
  • The ISCSI test has two network adapters, each on 1 Gbps ports
    • I can get around 800mbps per port when copying lots of files (both ports are active)
    • I see no error in copying a large number of virtual machines around, or backup files
  • I only see errors on start up and "rescan".
  • I have two network adapters on each host ESXi dedicated for ISCSI. Each NETWORK card has a single VMK. A single mapped port on ISCSI, the other is mapped to port B (I used to have two VMKs by nic, but I removed that in order to simplify everything)
  • I have updated the firmware on our switch of production. No results
  • I've used 4 different switches in order to avoid a network problem. No results
  • I tested ESXi versions 5.0, 5.1 (799733 & 1157734), all have the same mistakes
  • The ISCSI ports are on different networks according to the VMware (I was told not to put on the same network VMKs)

  Any ideas? It's starting to drive me up the wall. Any help would be greatly appreciated

  I've seen several times in recent months and was beginning to think it is specific to the HP P2000 units because it's the only time wherever I saw him! I now believe that ESX/iSCSI rather than issues of driver or table.

  On my last install, I found that errors occur as soon as the table is connected, i.e. before any storage is displayed.

  Single host ESX, no guests. 2 Intel adapters to 2 HP past by dedicated HP P2000 1 GB table with all 8 wired ports.

  All roads are good, all lights are in the State expected.

  It did not affect the use of the storage in question to any site, so there has been no need / a momentum of any further investigation.

  B! 886y annoying however!

• ESXI 5.5: Creating huge network separated on layer 2

  Hey,.

  I am interested in creating a network between the virtual machines of 300-500 connected to a single virtual machine separated in layer 2

  First of all I thought to insert all the machines in a portgroup and separate them with a VLAN, but it is not possible to connect the single to more than one virtual machine VLANs simultaneously

  Second, I tried to create a switch distributed with 300 exchanges (each portgroup has two ports - one for a virtual machine and the other for the unique virtual machine) but I found the maximum allowed per virtual machine network adapters is 10 so it is not possible to connect the virtual machine that is unique in more than 10 exchanges.

  I would be grateful for any other suggestions

  Thank you!

  What you want is an isolated PVLAN.

  This can be created on a dvSwitch. Put your unique virtual machine in the VLAN of promiscuity and all other virtual machines in the isolated PVLAN.

  Each of the virtual machines in the isolated PVLAN will be able to communicate with the virtual machine in the VLAN promiscuity but will not be able to communicate with any of the other virtual machines in the isolated PVLAN.

  It is quite easy to configure, change the settings of the dvSwitch and private VLANS tab, enter an id VLAN for the private VLAN on the right (this will be the promiscuous VLAN) and then to the left, enter an id for the VLAN secondary private and assign isolated. Now, create a portgroup to each of these VLANs and give them your virtual machines.

• How to create two separate networks in ESX that can communicate with each other with 2 x bear?

  Hello
  Just want to know a fundamental question concerning the configuration of my ESX host of singlebox with several vswitch and two teddy bears,
  What is the definition or use of the network Label and ID of Port? Yes VLAN, I know what it's meant for the physical world.
  My goal here is to
  1. create several vSwitch with much 4 VM on the two vswitch and it communicate somehow vswitch0 and vswitch1 happen? I need to plug the switch of pNIC2 for communication can / must travel through the network cable in my ESX?
  2. how to force all traffic Vmthe in a vswitch to enter a virtual machine that runs as a router VM and then talk to the other router vswitch VM? is this possible?
  Thank you.

  I do not know if I understand perfectly, but I often have to create isolated networks.

  In this case, there is only one NETWORK card, but it works with two, one on each switch. vSwitch0 can communicate with the outside world via the vmnic0. vSwitch0 and vSwitch1 are connected by the virtual router of pfsense. The virtual machines on the portgroup private connect to the world outside and any other VM on the portgroup VM network via the pfsense router. To access computers virtual private Portgroup requires a VPN connection via the pfsense router. This is a completely isolated network. With an additional uplink on vSwitch1, you can connect to other physical devices.

• VMotion failed independent network

  Hello

  Check this first: http://communities.VMware.com/message/1503426#1503426

  I followed this link to create the VMkernal in a separate network. But when I try to use vMotion, I get this error:

  A general error occurred: the VMotion failed because the ESX hosts were not able to connect to the network for VMotion.  Please check your physical network configuration and settings network VMotion.

  How to fix? Thank you.

  He should be able to ping its own IP VMkernel via vmkping, but as you said, even if this is not possible.

  The card NETWORK that you use for the VMotion listed as a NIC is active under the VMkernel properties (it can be active, pending or unused)? Scroll down in the properties of VMotion VMkernel (you already send a screenshot of).

• problem of traffic flow with tunnel created the network with a tunnel to a VPN concentrator

  Hi, I worked with Cisco and the seller for 2 weeks on this.II am hoping that what we are witnessing will ring a Bell with someone.

  Some basic information:

  I work at a seller who needs from one site to the other tunnel.  There are currently 1 site to another with the seller using a Juniper SSG, which works without incident in my system.  I'm transitioning to routers Cisco 2811 and put in place a new tunnel with the seller for the 2800 uses a different public ip address in my address range.  So my network has 2 tunnels with the provider that uses a Cisco VPN concentrator.  The hosts behind the tunnel use 20x.x.x.x public IP addresses.

  My Cisco router will create a tunnel, but I can't not to hosts on the network of the provider through the Cisco 2811, but I can't get through the tunnel of Juniper.  The seller sees my packages and provider host meets them and sends them to the tunnel.  They never reach the external interface on my Cisco router.

  I'm from the external interface so that my endpoint and the peers are the same IP address.  (note, I tried to do a static NAT and have an address of tunnel and my different host to the same result.)  Cisco has confirmed that I do have 2 addresses different and this configuration was a success with the creation of another successful tunnels toa different network.)

  I tested this configuration on a network of transit area before moving the router to the production network and my Cisco 2811 has managed to create the tunnel and ping the inside host.  Once we moved the router at camp, we can no longer ping on the host behind the seller tunnel.   The seller assured me that the tunnel setting is exactly the same, and he sees his host to send traffic to the tunnel.  The seller seems well versed with the VPN concentrator and manages connections for many customers successfully.

  The seller has a second VPN concentrator on a separate network and I can connect to this VPN concentrator with success of the Cisco 2811 who is having problems with the hub, which has also a tunnel with Gin.

  Here is what we have done so far:

  (1) confirm the config with the help of Cisco 2811.  The tunnel is up.  SH cyrpto ipa wristwatch tunnel upward.
  (2) turn on Nat - T side of the tunnel VPN landscapers
  (3) confirm that the traffic flows properly a tunnel on another network (which would indicate that the Cisco config is ok)
  (4) successfully, tunnel and reach a different configuration hosting
  (5) to confirm all the settings of tunnel with the seller
  (6) the seller confirmed that his side host has no way and that it points to the default gateway
  (7) to rebuild the tunnel from scratch
  8) confirm with our ISP that no way divert traffic elsewhere.  My gateway lSP sees my directly connected external address.
  (9) confirm that the ACL matches with the seller
  (10) I can't get the Juniper because he is in production and in constant use

  Is there a known issue with the help of a VPN concentrator to connect to 2 tunnels on the same 28 network range?

  Options or ideas are welcome.  I had countless sessions with Cisco webex, but do not have access to the hub of the seller.  I can forward suggestions.

  Here's a code

• VMotion slow 10gig NETWORK

  The host configuration:

  4 ESXi hosts.

  Reference Dell R610s

  Each has a service console connection standard 1gig with no VLAN.

  Network connections 2 x 10gig have each.

  10Gig connections are on Ethernet SFP twinax.

  10Gig NIC are dual port Intel NIC.

  10Gig switches are Juniper virtual chassis.

  There is a VLAN for the various networks that are routed

  There is a specific vMotion network that is not routed out of the data center.

  Problem:

  vMotion over 10gig link on the vlan vMotion top 1 Gb/s (~ 120 MB/s.)

  Regular traffic (iperf between two virtual machines) gets ~9Gb/s on vMotion network

  vMotion on regular networks gets about 9 GB of network speed.

  There is no firewall on these networks.

  The only difference between the ordinary and the vMotion network is the lack of routing.

  What can I take for my network guy as possible reasons vMotion would be slow?  VMotion makes any type of controls for butterfly itself to avoid ignored packets or something?

  Are the vMotion IP the same as network management network? If so, the internal routing table will make the decision and use the interface first in this range.

• How to create a network redundant ISP failover using 2 Airport Extreme

  Hello friends,

  I have 2 different lines of rented ISP related to my Airport Extreme 2. Was curious to know if these 2 AEs can be interconnected somehow to create a network of ISP failover. Users on AE 1 traffic would be transparent reassigned to the AE 2 and vice versa, if corresponding ISP fails. When the access provider is in place, they will return to their AE in elementary school.

  Thank you.

  Not without a smart dual wan router. That is to say done good load sharing.

  Extreme is about as simple a router you can find... He has the absolute minimum of functionality.

  Users on AE 1 traffic would be reassigned transparent to the AE 2 and vice versa

  You can do this by using some manual intervention... a simple change of entry door is usually sufficient.

• Airport of adjustment as separate network

  Hey, I'm trying to set up my Airport Express as a separate network. Right now it is connected to my Modem WiFi, but anyone connected to the WiFi on the modem can access anything that it is connected to the Airport network.

  Turn on the main router and run a full minute

  Then, turn on the AirPort Express

  The indicator light of the AirPort Express will be orange flashing slowly, but don't you worry about this right now

  Check the Terminal AirPort Express and other network to verify that the devices on a network cannot 'see' on the other network devices

  Keep an eye on things for a few hours. If everything seems, for the well being, you can tell the AirPort Express to ignore the error Double NAT, he complains, so that it displays a green light

  Double NAT may cause slow growth, no navigation, connecting from a remote location and other things, difficult, but you might be able to get away with Double NAT on a single network. Try it and see how it works for you.
