• 4pnics networks VLAN

  Hello

  Well, I am new to vmware.

  I have 2 guests and 4 natachasery by each of them and a hitachi storage 10 hus and a hp procurve 2824.

  When I do a vlan in esx must be the same number in hp switch?

  I would do any other setup in hp except where ports will be to this vlan?

  my scenario is 1 Teddy in vlan 10 vmotion and mgmt, 2 natachasery with iscsi VLANs 20 and the other for VMS vlan 30 / vswitches so 3.

  so I have a thin client and I want to connect with vlan 30 with the thin client vms.my is connected in the hp switch in vlan 30 / when I want to connect in any other t vlan for example I have a vlan 40 with other virtual machines.

  the hp switch automatically routes because it works also in layer 3? is that correct?

  the only thing I have to do is in my virtual machine to the network vlan 40 to add.

  for example when I in a Teddy 3 VLANS configured in vswitch port in the hp switch needs to be referenced, but when I have a vlan in 1 Teddy bear not tagged to the hp switch?

  Yes

  in the routing for gateway what ip I type for the 3 VLAN?

  It is up to you.  You must come up with a model of IP address where all the VLANS are on a different subnet and the IP gateway is part of that subnet.

• Multiple VLAN IDS vlan vSwitch

  I put several VLANS vswitch vlan id?

  Currently, I have 168 vlan and everything works fine, but I want my vmachines BA able to access to the vlan 163, so that I can just change vlan id fron 168 to 168, 163 or did only one vlan allowed?

  Hello

  to do this, you must create a second group of ports, with another id vlan and put a second Vnic on the PortGroup to the virtual machine.

  You cannot spend more than one vlan per port group.

• Design of Network\VLAN question

  I have a network completely flat and Im not a networking guy, but I have two ESX host, I need to build with a Lefthand SAN

  and I want to create a VLAN for vmotion traffic segmentation. Anyone know where I could find instructions to create the VLAN?

  I have 6 NETWORK adapters per ESX host and plan on using iSCSI software. I have also dedicated physical switches for my iSCSI traffic.

  How you prefer to use the 6-port network card?

  Awared points to answers.

  Hello

  You can assign a VLAN on each port group. VSphere Client, click on ESX / I have server you want to configure > click on the Configuration tab > then click on link networking in the hardware Section. Then click on the properties link in one of the vSwitch > select one port group, and then click on edit. Finally, you can assign a VLAN in the VLAN ID properties.

  The best way to use the NIC ports available, I think that there depends on your preferred configuration. For example, what kind of features you need to activate, the requirement for a network for each virtual computer speed, etc. But, basically, I have the same perception with the previous suggestion. You can allocate one or two ports for specific traffic.

• Advice on network VLAN using RV180W

  Hello!

  I want to create a network that allows to separate the traffic between two or three VLANS. I want to be able to connect wireless using two SSID assigned to VLAN individual. Also, I would be able to extend the zone wireless using a different Access Point. So far, I tried the best solution of equipment and I plan to buy the wireless router RV180W and WAP121 as an extension of Access Point. This configuration is possible on these devices?

  The structure of the network should look like this:

  

  The second Point of access on PORT 4 is just a future extension. It is not necessary at the beginning. I just want to know if it will be possible.

  I also link 2 PORT VLAN2 and connect it to the computer via Ethernet switch.

  Should I do VLAN2 and VLAN3 labeled with PORT3, PORT4?

  Thanks in advance!

  Hi Michal,

  In theory, that you try should work perfectly and Yes, you should make VLANS 2 and 3 tag on ports 3 and 4. Unfortunately, there is a problem with the RV180W which does not work properly with enclosed access points. I hope that this problem will be fixed in a future firmware version, but right now, I can't recommend the router for your particular scenario. Other than that issue, I have like and recommend the RV180W for general use Small Business firwewall/router. There are a few threads on this forum that describe the AP issue more in detail:

  https://supportforums.Cisco.com/message/3770136#3770136

  https://supportforums.Cisco.com/message/3980504#3980504

  The foregoing is not a problem with other SMB wireless routers as far as I know. I recommend that you consider the RV220W which has a better than the RV180W integrated wireless AP. It also has a more powerful processor and is very stable with the latest firmware installed. I tested a RV180W home and ended up buying the RV220W. I found that the scope of my environment was much better with the RV220W.

  Answer please if you have any questions.

• Are virtual network Interfaces, vSwitches?

  Hi all

  I read the following document http://www.VMware.com/files/PDF/dmz_virtualization_vmware_infra_wp.PDF

  And on page 7, where it says 'Set Layer 2 Security Options on virtual switches.
  Protection against attacks such as data snooping, sniffing and MAC spoofing by disabling the promiscuous mode, change MAC address and forged the capacity of transmissions on the virtual network interfaces. »

  How to interpret virtual network interfaces? Those are the vSwitches or group of ports VM?

  Thanks for your help,

  Those that are not the default values.  Change of MAC address: Rject and forged passes: rejection would be the default values.

  But before you change them - they don't automatically indicate a security problem - you need to know why they changed first.

• Management network on vswitch even as traffic of the vm?

  Research on how our environment Vsphere has been configured and I noticed that they have the management network on the same vswitch because the traffic of the virtual machine. There are currently 2 connected network adapters this vswitch.

  I know that the configuration is not recommended, I wonder if I should change and what the best way is to change it?

  Move management traffic to a new vswitch or move the traffic of the virtual machine to a new vswitch? I have 2 more physical network card, so I can add an another vswitch with redundancy.

  Thanks for your suggestions.

  Kevin

  It would be best to move the traffic of vm, simply because when you change your management traffic, literally creating a new interface vmkernel, and by assigning the gateways and which can lead to a decline in the connection.  Simply create a new vSwitch for traffic of the virtual machine, create a new portgroup and re - assign the virtual machine.

  That being said, it is 'better' keep the two separate, but not a condition difficult.  If you have network cards, then this is definitely a "nice to have".

• Security VLAN vSwitch

  Hello-

  It's been some time that I made any VMWare implementation and when I did, it was the v3.5 for small and medium-sized business customers. Therefore, I didn't need to take advantage of many of the VMware and vSphere tools providedin. Since the time I focused mainly on networks and network security.

  In a vSphere environment, we have a VLAN separate configured for backup. We are concerned about the safety of the VLAN, as all the servers that have an intervace on this VLAN backup can communicate with all other Cisco VMs. and HP switches have a feature 'protected port"that allows no ports configured as 'protected' to communicate with other ports configured, even if they are in the same VLAN.

  My understanding is that ESX 3.5 did not support this feature. It was accidentally introduced in vSphere? If so, which version?

  Looks like you describe PVLANs (private VLAN), which allow you to implement similar to what you describe...

  Check out these links for more information...

  And also...

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalID=1010703

  To answer your question, this feature is supported in vSphere 4 and 5, you have a distributed Virtual Switch need configure it, so you would need a license Enterprise Plus I think

• VLAN and physical and vSwitch Configuration

  I am trying to set up a laboratory at the House and recently bought a new physical switch with the goal of creating a number of VLANS to segment the different networks with router controlling access to each network.

  The router is configured with 4 networks of each on a separate interface:

  • 10 - home network network
  • 172 - network management
  • 192 - laboratory network
  • Internet

  These are in turn connected to a single physical switch. I wish that my switch to have 3 VLAN to match each network. Guests on these VIRTUAL LANs can be physical or virtual. A network adapter on the server vSphere will be bound to a vSwitch and connected to the VLAN respective on the physical switch to enable connectivity for virtual hosts.

  Can someone explain to me what to leave a VLAN tagging perspective in order to get this to work and now the separation between networks?

  I tried a combination of marking on the physical and virtual switch and impossible to get full connectivity to the physical and virtual hosts. For now, I have three VLAN (default value (1) where is my network 10), 172 and 192.

  I can ping the physical hosts on 172 and 192 VLAN but I can't ping any invited virtual.

  I can ping hosts physical and virtual a virtual guest on any other network.

  The router has not at all of any configuration of VLAN.

  Thank you

  Hi Adam,.

  I can give you an explanation of how I could do this using cisco equipment.

  You say you have 4 NICs from your host and would have networks vlan, so a very simple way to do this would be to create the VLAN on the switch. Define each of the physical network cards on the switch to be an access port to the vlan correct. Personally, I'd be trunk all interfaces, but access is easier to explain...

  If an example (cisco config)

  Interface 1 on switch access to vlan 10 - Conf t, IM 1 interface, switch mode access port vlan, switchport Access 10

  interface 2 on the access of the switch to vlan 172 - Conf t interface IG 2, switch to access port, switchport access vlan 172

  etc.

  When you create your vswitches, select the correct uplink, create a network of the vm by vswitch, you would not need to specify a vlan.

  If you wanted connectivity between virtual LANs to happen in the switch, assuming you have a l3 switch, you can give the VLAN IP addresses to the correct subnet, use it as the gateway for customers and enable ip Routing.

  Access to Internet; How I have this setup in my lab, it is that I have a trunk between the switch and the router, allowing the VLANS on my networks that require the traffic internet, my router has sub interfaces defined on the network for each virtual local area network interface. These submarines have an IP address in the correct VLAN (all clients use this as the gateway). Internet link is connected outside the router and which deals with the nats and routing between VLAN etc.

  Another way to do would be to have an extra virtual LAN on the switch to which connect your router, give them two ip addresses, use the switch to route 0.0.0.0 0.0.0.0 for the IP address of the router. You would need to implement Nat for each network, and no doubt some allow lists but its possible.

  Not as easy to explain as I thought when starts this...

• In ESX VMs can choose different network/name of the label (VLAN)

  Hi guys,.

  My test vCenter crashed and I can't get it back as there is no backup. I can only connect directly to the ESXi servers and use virtual machines from there. Now, I am facing a problem while deploying a new virtual machine and by changing its network. I have a vDistributed configured switch that has 2 groups of ports 10 VLANS and VLAN 30. When I create a new virtual machine, it only let me choose VLAN 30 and will not let me choose VLAN 10 while there are a few old VMs that are still configured for VLAN 10 and I can change their card NETWORK VLAN 30. Should what changes I make to configure the VLAN 10 on my new virtual machines?

  I have 2 ESXi servers and this is the case even on the ESXi servers.

  Please find the attachment.

  Any help would be appreciated.

  Kind regards

  Hello

  The type of binding of default ports is a static binding, which means that you can connect to a virtual machine for a link static port group only through vCenter Server.

  I guess, the port VLAN 10 group is created with a static linking.

  VMware KB: Choose a type of port binding in ESX/ESXi

  If you do not group ports with ephemeral connection, you cannot connect a new VM for VDS if your vCenter is out of service.

  With connection of ephemeral ports, you can assign a virtual machine to a group of ports on ESX/ESXi and vCenter, which gives you the flexibility to manage the connections to VM through the host when vCenter is out of service.

  In this case, you will need to temporarily create a new vSwitch directly on a host with VLAN 10 to connect the new virtual machine.

  More info about ephemeral port binding:

  VMware vSphere Distributed Switch allows the management of the ephemeral ports while vCenter is offline. Vcritical

• secure network on vlan

  Hello

  We have recently implemented VOIP company.

  Our PBX did not have the option for VOIP and was connected to our network for security reasons, because our PBX partner has access to the PBX to support reasons. After upgrade from PBX VoIP, it is connected to our network VLANs separated.

  I wonder what the best solution is to make sure that our partner has no access to the rest of our network? Only the VLANs VOIP should be accessible from their side.

  All VLANS can communicate between Via router which has configured VTP domain.

  You can place an ACL on the router. But you have an interface with an ip address for vlan 20? The router uses sous-interfaces for vlan 20?

  If so the I would

  access-list 120 permit
  access-list 120 permit
  access-list 120 permit
  access-list 120 permit
  ...
  int vlan20
  ip access-group 20 in
  

  Now if the router has just one of his ports connected to a port on the swiitch for vlan 20 and it has an ip address on this interface, and then apply the ACL on the interface instead of the vlan.

  I hope that makes sense.

• VLAN again added, problems detected on guests during the detection of new network configuration

  Hi all

  I started facing a strange problem trying to use a new VLAN configured in my vCenter environment...

  Basically, my system 'fight' to identify the new network label (VLAN) configured, leaving systems disconnected from the local network.

  This condition disappears only when I change the VM touched, assign a label of different network (VLAN), apply the changes and restart the process by configuring the new VLAN return.

  We will use an example to explain better:

  • I have a named Windows Server/Workstation VM: VM1
  • I have 2 VLANS configured in vCenter: VLAN50 and VLAN70

  VM1 is sitting on the VLAN50 and has the static IP address configured.

  I start the migration of the machine to a VLAN different, by editing the network settings of the operating system (IP, MASK, GW, DNS entries...) and replace the label of VM1 VLAN70 network.

  At this point, the machine NIC shows as if it could not connect to what in the network, although it is configured accordingly in order to communicate in the new subnet.

  I have change the VM again and change the label of a network VLAN different from VLAN70, click OK. Immediately, I change VM settings to assign in return the VLAN70.

  After that, the operating system recognizes the network successfully and starts working as expected...

  All of my virtual machines use VMXNET3 adapter and my version of vCenter is v5.5 build #2646482

  No idea what might happen?

  Concerning

  We found the problem...

  It was not associated with VMware, but a network configuration problem: (ESXi connected to two switches, one of them with the VLAN configured correctly and the other does not...).

  Thanks for the help

• The ESXi Server network configuration

  Hello

  This is a pretty silly question for most of you, but I don't have any experience on ESXi.

  If an EXSi server has 4 installed physical network cards, this means that it can only subnets different hosts 4? they are more than 4 subnets to be hosted, one or more servers need to be purchased ESXi?

  Thank you

  Hey Roywang,

  You can have as many subnets you want as long as they are all set on your physics of switching.  For example:

  VLAN 100 - 24 10.1.1.X

  VLAN 200 - 10.1.2.X 24

  VLAN 300 - 10.1.3.X 24

  VLAN 400 - 10.1.4.X 24

  VLAN 500 - 10.1.5.X 24

  VLAN 600 - 10.1.6.X 24

  VLAN 700 - 10.1.7.X 24

  Now, with these VIRTUAL networks, you can cut your vSwitch like this upward:

  vSwitch0

  PortGroup - management - VLAN100 - 10.1.1.5/24 active VMNIC0, VMNIC1 ensures

  VMotion PortGroup - - VLAN 200 - 10.1.2.5/24 VMNIC1 active, VMNIC0 ensures

  PortGroup - VM Network - VLAN 300 - VMNIC0, VMNIC1 Active 10.1.3.5/24, active

  PortGroup - VM network WebServer - VLAn 400 - VMNIC0, VMNIC1 Active 10.1.4.5/24, Active

  PortGroup - VM Network Backup - VLAN 500 - 10.1.5.5/24 VMNIC0, Active, Active VMNIC1

  vSwitch1

  Port - iSCSI1 - unused VMNIC2 VMNIC3 Active 10.1.6.5/24 Group

  Port - iSCSI2 - 10.1.7.5/24 VMNIC3 VMNIC2 Active unused group

  What is happening is essentially in your vSwitch each port group gets a tag VLAN, then on your physical switches where the nics connect tag, what is needed, and the switch will forward the packets accordingly.  For example, the ports that vmnic0, vmnic1 plug on the physical switch you would tag for VLAN 100,200,300,400,500 like all these networks can land on each network card.  You will also need these trunks in trunk for this mode.

• Group of port and the naming convention for vLAN

  What is the naming convention better for groups of ports on vSwitches?  This naming convention should match how we name them VLAN on the physical switches and how important is that?

  Hi VMinator,

  To answer your question, he has not agreed to 'standard' for names of portgroup.  That's all what you're comfortable with the support and what works for you and your organization.  A bit like server names; Some companies are going hardcore with the naming conventions and others their name after the characters in science fiction or world of warcraft bosses

  Forensic science more you pack in a naming of the control standard more you have (i.e. for scripts, health check, etc. see below).  Also, if the name itself answers questions on his own and allows you to save a phone call that is priceless.  For example - the guys says unix... "Uh which network to choose for my new virtual machine.  My IP is blah blah blah. "Well, with right portgroup name, this question would have answered itself... and maybe even recorded some interruptions of service in other cases by the simple fact of being clear and effective in the communication of how this virtual device should work: purely expressed through an appropriate naming convention.

  Here's another one.  My last concert, we had thousands of virtual machines that had to move data centers and when they landed, they needed to change the IPs and start using 3 vNIC (instead of 1) on each virtual machine.  Each vNIC with a different subnet mask.  All support should be conducted by a team of outsourced with minimum experience of VMware.  The only way to support something like this and be effective is PowerCLI.  With just invited the naming convention only, you can perform various tasks such as query the virtual computer and check its settings of portgroup compared to its actual IP information in the operating system, initiate a ping from .NET to the virtual machine, if there is any questions Act automatically.  Some actions that will have to be performed include, for example, change the portgroup or mask on a set of clients;  Or questioning guests and glean information network (CDP, vSwitch, portgroup of information etc.) and compare observed network vs network expected enumerated in the PG naming convention. etc etc.  The list of actions that you can take are limited only by your creativity.  The naming standards give you effective power both in manual and automatic efforts.

  Still, notice of one man, but every site I care and feeding generally ends with a PG standard similar to what I first described above in my previous post.  Don't forget my example naming convention is Basic.  There are many other attributes that you can add (i.e. in vCloud deployments, in addition to the info network, you can choose to identify various features specific to vCloud org-networks, etc.).

  TBH just most of the companies have appointed VM-network exchanges (ok not bad) or some random shortname which doesn't help troubleshooting.  They are fairly easy to fix and also change over time, if necessary.  You can easily drag and drop a set of virtual machines (although I don't personally do this way) in the new port group (via the page of networking to CTRL + SHIFT + N) or PowerCLI it (Yes!  way to go).  Of course, always the ping tests before and after the change.  There are a lot of scripts out there (or ask master lucd post in PowerCLI VMTN forums).  If this is net-news, then you are ahead of the game and will have a standard to follow, whatever it is.

  Best of luck and have fun!

• ESXi and VLAN

  Hello

  I am facing a problem that you are trying to use VLANs in Esxi. Here's the scenario.

  A HP Blade as host.

  A HP GbE2c Ethernet blade switch.

  Allied Telesis switch connect the box to the network.

  Vlan1 - 192.168.1.0/24 (5 VM).

  VLAN2 - 192.168.2.0/24 (1 VM).

  5 virtual machines residing in the VLAN1 use vSwitch0 in a portgoup named VM network VLAN ID 0. The virtual machine in the VLAN2 uses vSwitch0 in a portgroup named VLAN2 with VLAN ID 2. The port in the Ethernet switch of the blade where the Esxi host is connected is labeled for VLAN 1 and 2 to pass. Also link ports Allied rising connection with switch blade are also marked for both VLAN.

  I'm doing something wrong? As soon as I change the connection port to the Esxi host to the switch blade for the tag, I lose the connections with all virtual machines (MY PC is in VLAN1 connected to the Allied switch).

  Thank you

  Can you change the VLAND 1 in vSwitch (port network VM group)
