• ESXI hosts 5-2 and the best way to configure vSwitch and Nic redundancy

  Hi all

  Could someone help me find the best way to configure the vNetwork on 2 5 ESXI host for redundancy.  Once I managed to correctly configure the 2 hosts I will seek to use the same installation process for 6 guests.  3 sites with 2 hosts on each site managed all of vCentre Server

  I have 2 DL380 G7 servers 5 ESXI installed on a class 10, 8 GB SD card, I'm looking to install VSA on the 2 hosts on each server with 4 TB of internal storage (8 * 600 GB 10 k SAS).  Each server has a gigabit integrated 4-port NIC and I installed a 2nd NIC gigabit PCIe 4 ports, I also x 2 16 switches of port with Layer 3 routing.  I use vSphere 5 Standard acceleration Kit I am looking to use vCentre server for managing, vMotion for maintenance, HA for the failover and VM 10/15 (vCentre Server Std, DB SQL to vCentre Server, Exchange 2010, SQL Server 2008 R2, IIS Intranet, Helpdesk, 1 DC, 2 Domain Controller, AV Server, WSUS, SCCM Server, and Terminal Server server).

  What would be the best way to install and configure the network for performance and redundancy and am I missing something?

  My thoughts are, Teaming: -.

  vCenter - vswitch0 - port1 on NIC1 and port1 on NIC 2 - port1 on NIC1 to physical switch 1 - port1 on NIC2 to physical switch 2

  vMotion - vswitch1 - port2 on NIC1 and port2on NIC 2 - port2 on NIC1 to physical switch 1 - port2 on NIC2 to physical switch 2

  HA - vswitch3 - port3 on NIC1 and port3on NIC 2 - port3 on NIC1 physics 1 - port3 on NIC2 to physical switch 2 switch

  VM - vswitch4 - port4 on NIC1 and port4on NIC 2 - port4 on NIC1 to physical switch 1 - port4 on NIC2 to physical switch 2

  or do I need an additional NIC on each server to hit the VM 12-6 VM for 2 ports on 2 NETWORK interface card, or maybe something else I missed?

  Thank you

  In your case, to keep it simple and what I can say here is what would be my recommendation:

  3 standard vSwitches

  vSwitch0:

  • Management - vmnic0, vmnic2

  vSwitch1:

  • vMotion - vmnic1, vmnic3

  vSwitch2:

  • VM network - vmnic4, vmnic5, vmnic6, vmnic7

  The only reason why that I didn't split the VM in other network adapters shipped is because the difference in the types of the DL380 adapter shipped and the PCIe quad.

• Why do I need "Promiscuous" Mode when you use multiple vSwitches and a bridge?

  Hello guys,.

  5.5 ESXi running.

  I created two vSwitches and putting multiple virtual machines in each vSwitch. I have a CentOS VM with two network cards, one in each vSwitch. I configured the CentOS VM to work as a bridge. I could spend between devices on a vSwitch pings, but ping has no devices on a vSwitch devices on the other (through the CentOS acting as a bridge). The ARP requests have been sent across the bridge, but have never had sent answers ARP. I checked around online and someone recommended to enable Promiscuous Mode. I activated the Promiscuous Mode (changing to refuse to accept) on the two vSwitches (which is then applied to the change to all virtual machines). You can read more about that here: VMware KB: how "Promiscuous" mode operates on the virtual level switch and portgroup

  Now all of a sudden, everything works.

  My question is: why?

  I think that I don't want to Promiscuous Mode unless it must be such that it will result in more traffic to each VM it had reached before. I don't really understand why I need to authorize this change, and any help would be nice!

  Without promiscuous mode, vSwitch and port group will only transmit traffic VMs (MAC addresses) that are directly related to the port groups, he will not learn the MAC addresses that, in your case, are the other side of the bridge. The "Promiscuous" mode, all traffic is sent to each virtual machine on the vSwitch and port group and it's virtual machine to decide what to do with the network packets. As you have already mentioned, this isn't a parameter that you want to apply to a large number of virtual machines. For this reason, you can create a second group of ports on the vSwitch with only of CentOS virtual machine and activate the "Promiscuous" mode on only this group port rather than the vSwitch.

  If virtual machines are on the same vSwitch and VLAN traffic is not struck the physical network adapter.  If virtual machines have been on different vSwitches, traffic would hit the physical network.  Even if the virtual machines are on different VLAN traffic would pass through your router.

• vSwitch and Portgroup security settings

  I'm looking for a way to query the security settings ("Promiscuous" Mode, forged passes and changes of MAC) the vSwitches and exchanges. MY PS skills are limited. I can get about this until now especially of patching together various scripts that I found. However at this point, I provide a vSwitch and even when I am able to get this information I don't know what to do after that.

  {Foreach ($VMHost in Get-VMHost)

  Foreach ($vSwitch to ($VMHost |)) Get - VirtualSwitch)) {}

  $hostMoRef = get-VMHost $VMhost | % {Get-view $_.} ID}

  $hostNetwork = $hostMoRef.configManager.networkSystem

  $hostNetworkMoRef = get-views $hostNetwork

  $hostNetworkMoRef.NetworkInfo

  }

  }

  PowerCLI 4.1, you can use the property, Extensiondata get to the managed object.

  To display the list of all your vSwitches and their exchanges, security settings, you can do something like this

  foreach ($VMHost in Get-VMHost){
       foreach($vSwitch in $VMHost.ExtensionData.Config.Network.Vswitch){
            Write-Host $vSwitch.Name
            Write-Host "`tPromiscuous mode:" $vSwitch.Spec.Policy.Security.AllowPromiscuous
            Write-Host "`tForged transmits:" $vSwitch.Spec.Policy.Security.ForgedTransmits
            Write-Host "`tMAC Changes:" $vSwitch.Spec.Policy.Security.MacChanges
            foreach($portgroup in ($VMHost.ExtensionData.Config.Network.Portgroup | where {$_.Vswitch -eq $vSwitch.Key})){
                 Write-Host "`n`t" $portgroup.Spec.Name
                 Write-Host "`t`tPromiscuous mode:" $portgroup.Spec.Policy.Security.AllowPromiscuous
                 Write-Host "`t`tForged transmits:" $portgroup.Spec.Policy.Security.ForgedTransmits
                 Write-Host "`t`tMAC Changes:" $portgroup.Spec.Policy.Security.MacChanges
            }
       }
  }
  

  Note that the a security framework for a portgroup will be empty (= not) when he uses the corresponding inherited vSwitch parameter.

• How to see the VSwitch and PortGroup properties in the managed object browser

  Hello

  We have a laboratory infrastructure VI3, with a VC and some ESX servers running.

  In the managed object browser, I'd like to see the properties of certain objects,

  especially the VSwitches and exchanges.

  How do I see VSwitch and exchanges from the CROWD. Here's my data:

  ESX IP address: 192.188.0.228

  VSwitch name: vSwitch0

  The port group name: VM_PG

  I know that we can see these properties of Client VI, but I really want to see values

  returned for each of the attributes defined in the WSDL file and the CROWD precisely

  allows me to do. This will help me to do a bit on our end of modeling.

  I tried, but I couldn't really vSwitch. Grateful if someone can give inputs.

  Thank you

  Try this:

  https://A.B.C.D/mob/?moid=ha-host&doPath=config.network
  

  and more precisely which lists out them the portgroup and vSwitches

• vswitch\pswitch and NIC load balancing

  Hi all, I would like to pass a scenario by you all to see if I'm on the right track...

  We have 2 guests with DAS each and the vswitches to connect with 2

  1 GB card physical network of a pswitch (spine) of the spine, I have 3.

  2nd level going @ 100 MB / who joined forces 1 GB connection to the

  spine. With me so far?

  Now, I think that the network knows contension request that

  Sometimes we lag eg: switching shared printers printing

  Server, digging the network shares, etc...

  I have check the performance data on the host computer and I see not heavy

  bandwidth, the cpu, the disk activity load. I check the NETWORK card and it

  appears only 1 never get used even if I don't know they are associated

  correctly.

  I decieded to get another switch of the same spine model and plan

  to use the covering tree weight to connect backbones and with network cards

  Separate them each to the spine and then another tree covering weight

  in each office, idea that switching will be better

  spread the load across the two NIC to the vswitch...

  At present, there are only 2 NICs in each host, I have another 2

  cards Go transit and 2,100 mb NIC to use for the console. I plan to use 2 news

  NIC Go for interhost connectivity and create a virtual SAN for extra

  space on each DAS.

  I've attached diagrams of deouifinecomptent Rapids and the proposed crossing and also how I could team up on the vswitch...

  Thank you for your time!

  That's what I've got to meet the night - if you change your IP Hash the vmkernel will review each IP packet out and based on the IP address of the source and the destination the vmkernel wil choose the physical NIC connected to the virtual switch - so for an example, and I will keep it simple assumes that you don't have a simple VM with a single virtual NETWORK adapter connected to the virtual switch - now lets look at two examples possible

  1. The virtual machine is a web wean provideing conebt to multiple users - each IP address of the V will remain constant, but each user will have a different IP address for traffic coming out will be distributed in all of the cards of physoical connected to the virtual switch.

  2. The virtual machine is an application server to connect to a physical SQL Server - in this case the starting and destination IP addresses will not change if the traffic go on a physical network adapters

  Hope this cleared up-

• Networking ESXI establish two vswitches and 2 NICs on different networks.

  OK hope someone has an idea.

  Have two network cards and just connect the second network card but my setup requires that the first NIC physicle

  10.10.0.0 network, 255.255.255.0 subnet, Gateway, Vswitch 10.10.0.105 0.

  the second nic physicle

  100.100.0.0 network, 255.255.0.0 subnet, 100.100.0.1 gateway Vswitch 1

  I need the machine virtual first Vswitch network and some on second Vswitch network.

  At the moment I don't see how to set the ip address of the second network card or the gateway?

  Is there a way to do this?

  I have the updated Vswitches in place ok and network adapters are attached to the different vswitches.

  When a physical NETWORK card is assoiciated with a vSwitch, he is forced to behave like a shared on a physical switch port. However, there is more no uique to the physical NETWORK adapter configuration. It passes the traffic of the VMs and the core of the virtual machine to the physical network as an uplink. MAC addresses and IP addresses inside the frames come from virtual NICs attached to the virtual switch.

  You define IP addresses and default gateways within the virtual machines and any VMkernel ports connected to the virtual switch.

  Another way of thinking, is pretending the ESXi server has swallowed a bunch of switches and cards network is now the switch ports. You connect a box full of switches to your physical infrastructure, not a 'normal' server

• Laboratory of network of production using rdp Server 2 NICs (1 connected to prod vswitch and 1 single vswitch)

  Hi all

  I have a copy of my DC prod and a few servers on the host esx5 I created a single vswitch (no assigned network card). Besides all the vms on the isolated vswitch laboratory has no (empty) assigned default gateway ip address. Security measure. Let me explain briefly... everything is good so far... .but to access virtual machines on isolated vswitch, I need to connect to vcenter console to virtual machines. It's ok but very slow heavy and slow ...

  I thought to create that a virtual machine allows to call him my rdp Server I'll rdp on prod, then this machine virtual, I'll rdp on vms on isolated network lab. configuration of the server rdp as follows.

  I assigned 2 network cards to the rdp Server (to connect to prod vswitch network and another vswitch isolated), now my question is this secure?  which means in any way I want my isolated vms on vswitch lab test connect to servers of prod, this woulkd be a nightmere. As I am unable to ping test prod servers from computers virtual lab, and I wasn't expecting to. remember as a precautionary measure, I do not use a gatewate desktop virtual lab and I can only ping the server rdp... .so far so good

  Please let me know thoughts or maybe someone has put in place in the past...

  Thank you

  Yes it's course - internal traffic only network is isolated from the network of productin you - that traffic will come out is if place a router between the two networks

• vSwitches and network traffic internal vs external

  In an effort to reduce copper that we adopt 10 GB NIC on our ESX 4.0 servers. This means that we will have many more VMs sharing a physical network card. Our network security architecture is such that servers are separated in different segments of network with access restricted by ACL in the physical network equipment, it is used to separate the databases of web servers, etc..  A question arose about the traffic that can pass between virtual machines but never cross the physical network.

  Linking rising 10 GB nic is connected to a port to shared resources, so we have two virtual machines that have different network segment addresses (different VLAN) will be communication between virtual machines only crosses the vSwitch or will be the release of traffic the ESX Server through the ACLed interface and return on the other virtual machine via the same uplink port?

  I thought that, given that each virtual machine has a gateway address specific, that traffic had to leave the ESX Server. But then again they will be on the same vSwitch if...?

  Kind regards

  Garrett

  If they are running on the same host, the vSwitch works as a physical switch, so, ideally, you can move the data of Vlan. . but in order to browse the segments, you need to hit the gateways defauilt for each segment.

  If your DG isn't on the ESX host. . Unfortunately, you're going to the physical network.

  How to keep the traffic on the Local host is to use Private Vllans to segment the traffic, or you can also install a VM device that can manage your default gateway (router on a stick) of routing

  If you have the device to your traffic. everything is local. otherwise. . Physical switch will not only take the traffic, but distribution to the next layer so that it can be done correctly.

  I want to install CUCM 8.5 is the NIC Teaming/failover supported by UCS C200 and how to set up the NIC Managment interface with failover?

  Thank you.

  Hello

  As you install apps from the CPU on the server of the UCS, speech application team listed their recommendations here.

  http://docwiki.Cisco.com/wiki/QoS_Design_Considerations_for_Virtual_UC_with_UCS#Guidelines_for_Physical_LAN_Links.2C_Trunking_and_Traffic_Sizing

  You can create a NIC teaming in the ESXi via vSphere client software for traffic from from / destined for virtual machines.

  For C200, we have only one management port and if you use the management for MMIC traffic port, switch option is not available.

  However, if you choose to use host for MMIC traffic NETWORK ports, you can set up CIMC NIC mode for 'LOM shared' which provides the NIC teaming options.
