• Get rid of the physical switch between 2 ESXi - Layer2 virtual servers between boxes

  Hello

  It's maybe a stupid question, but I can't quite understand the answer so I might as well ask.  I have two physical hosts of ESXi in my lab and for various reasons wish to eliminate the physical switch between them, but while retaining full vSphere functionality (HA, vMotion, DRS etc.).  Is there a switch virtual/Repeater product can I buy/use (deployed on the two ESXi hosts in a HA configuration) who can give me this feature?  I would then use Teddy ports on each ESXi host to talk to each other and additional natachasery as switchports to the outside world.  i.e. can I do this with a kind of multi-Vyatta router configuration?  NSX?  Must also support multicast.

  Thanks for your help!

  If you want to get rid of the physical switch, simply do not use it. ETH-cable to directly connect the natachasery of these two hosts of ESXi. If your NICs have the ability to auto-mdi (x), there is no something special. Some older NICs may still require cable crossover, but this is not necessary with new hardware...

• interoperability of the aggregation of link with Nortel layer 2/3 copper GbE Switches and DELL 6200 Series

  is it possible to create an OFFSET using LACP between a pile of 6224 dell and nortel switches layer 2/3 ethernet (reference 32R1860) GbE switch modules

  Im sure I have the command of the nortel switch, but not sure about the DELL printer.

  How to check the link is active?

  You can define a dynamic LACP LAG with this command

  Console # channel - group 1 automatic mode

  Auto is the key word, the other option is on where is in turn on blindly without confirming the connection is valid.

  When you use the automatic command, that he should not work if the other side is not also configured to use LACP.  It is built safely to avoid a loop. Who can go unnoticed.

  Use the show command to ethernet lacp in privileged EXEC mode to display

  Information on LACP Ethernet ports.

  console #show lacp ethernet 1/g1

  This command should provide information confirming that the LAG is active.

• How to add the physical switch/router to NSX

  Hello

  I check several labs and I have a big question unanswered!

  How can I add physical switch resources to NSX?

  on each of the scenarios, it assumes that you have a few physical interfaces on each host, and you can assign them to a VDS.

  It's good, but it was also available on old vCenter without NSX.

  For example, how can I add switch 24 ports 10 gigabit Ethernet on my Brocade switch to the VMware resource pool?

  Thank you

  You are welcome, of course.

  The network virtualization is not on the ability to win, but it's rather on the use of the available capacity of more flexibly to maintain security between virtual machines without worrying about the port based firewall or port-approaches physical configurations and physics on the VLAN externally in your virtual infrastructure.

  Just as the server virtualization adds capability to your server infrastructure, it allows a more flexible use of the physical capacity that is available.  You must you the capacity available to the involved hypervisors.

  See you soon!

• What mac - address is visible to the physical switches?

  I have a Dell crowd with 4 natachasery and vSphere 4.0 hypervisor. natachasery is attached to a physical switch. Switch does not support the CDP Protocol (does support LLDP). Data folding switch, I don't see the mac addresses of Dell natachasery. Instead, I see mac with VMWare OUIs addresses (00: 0C: 29:xx:xx:xx).

  What address is seen the switches? Where can I find these addresses mac VMWare VI Client hypervisor or MOB? Is - this vSwitch mac address (I couldn't find vSwitch mac address anywhere in the VI client)?

  In the CROWD, I see after the objects under HostNetworkInfo:

  Teddy [PhysicalNic]
  * Teddy [' key - vim.host.PhysicalNic - vmnic0 "]
  * Teddy [' key - vim.host.PhysicalNic - vmnic1 "]
  * Teddy [' key - vim.host.PhysicalNic - vmnic2 "]
  * Teddy [' key - vim.host.PhysicalNic - vmnic3 "]
  PortGroup [HostPortGroup]
  * portgroup ['key - vim.host.PortGroup - VM network 16']
  * portgroup ['key - vim.host.PortGroup - network management']
  * portgroup ['key - vim.host.PortGroup - VMKernel']
  * portgroup ['key - vim.host.PortGroup - MLAG test bench"]

  My understanding was that this mac address would be at the level of vSwitch and not at the level of the port.

  Y at - it an another simple way to find (via LLDP?) where the host is connected (vSphere 4.0 or 4.1 vSphere)?

  Thank you, in advance.

• Does Windows natively support the aggregation of links?

  There are some descriptions on the aggregation of links in Wikipedia.

  http://en.Wikipedia.org/wiki/Link_aggregation

  "Note that Microsoft Windows does support not natively the aggregation of links (at least until Windows Server 2008)."

  I was wondering if this description is accurate? And what about the new windows operating system, such as Windows Server 2012 edition?

  Windows xp, Windows 7 and Windows 8 natively supports the aggregation of links? If the answer if not, anyone know why? I know, Linux and other operating systems support the aggregation of links.

  Hi, Peacegump,

  For NIC teaming or link aggregation support, you will need to contact your provider network adapter or an OEM (for example, Dell offers a driver of consolidation).  They provide you with a driver that allows the grouping of NETWORK adapters, because Windows does not offer this feature in the core of the operating system.

• 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.

  If you have any questions please let us know.

• ESXi 5.5 nic teaming/LAG with trunking does not but it works on ESX 4.0.  Both are on the same switch. What gives?

  I have two hosts (vhost1 = ESX 4.0, vhost2 = 5.5 ESX) both are configured for the Group and both connected to a switch of 1544 Adtran L3 (named sw01).  vhost1 has been in production for several years with the config below and has been solid as a rock.  I'm trying to reproduce the installation of grouping/collage on vhost2 and it does not work when are associated but will work when you are using a single NIC (with or without aggregation).

  To be more specific about what does not work, two virtual servers have "Network server" (vlan 8) defined as a group of ports. Both physical and virtual servers on the same vlan cannot ping or resolve queries arp for virtual machines on vhost2.    Everything that is sent from a different subnet can connect to the virtual machines on each virtual server.

  So the question is this: why not ESX 5.5 works as ESX 4.0 when the configs are also near identical, as I can make them and they are connected to the same switch?

  Thanks for any input you can provide!

  Hello

  Do you share the vmnic for ESXi management and network of the VM?

  Try to follow the steps in this KB: VMware KB: NICs using EtherChannel grouping allows intermittent network connectivity in ESXi

  Trying to team adapters using EtherChannel, network connectivity is disrupted on an ESXi host. This problem occurs because grouping NIC properties will not propagate to the network management portgroup in ESXi.

  When you configure the ESXi host for grouping of NETWORK cards in attributing to the road based on ip hashload balancing, this configuration is not propagated to the portgroup management network.

  Workaround

  Note: to reduce the possibility network loss please change the route based on the hash of IP using this method of balancing load vSwitch

  1. Close all ports in the physical switch team leaving a single port as active.
  2. Change the Route based on ip hash vSwitch and load balancing management Portgroup.
  3. Set up the physical switch port channel.
  4. Activate the physical switch ports.

  Notes: Using this method will avoid a loss of connection when you switch to a port channel. Also make sure that under the properties for vmk portgroup # used for network management you tick the box "Enabled".

• Circuits on the physical virtual network

  Hello

  I'm trying to implement trunking to route traffic to vlan tagged from the virtual to the physical.

  I have a cisco 2900 2 layer switch series.

  I created a virtual swtich and have only 1 portgroup for now. The portgroup must have 4 VLANS. I have configured the parameter vlan in the portgroup 4.

  On the physical switch I configured the port that connects to the esx NIC that the virtual switch uses an uplink as follows:

  conf t

  int fa0/7

  switchport mode trunk

  No tap

  When I use sh int trunk command I can see that the port is certainly the installer on the trunk and is using 802. 1 q encapsulation.

  I joined a virtual computer to the vSwtich and the portgroup which is put in place for the vlan 4

  I have setup the next physical port on vlan 4 as an access port.  and connected to a laptop

  The laptop computer and the virtual computer are in the same subnet, but they cannot ping each other.  Later, I'll add other exchanges to other VLANs to the swtich, but I want to get the connectivity on the trunk port before proceeding.

  Anyone know what I am doing wrong?

  Thanks for any help

  There are a few additional settings, you may need to configure the physical port. Take a look at http://kb.vmware.com/kb/1004074 for an example of configuration of VLAN.

• MS NLB Multicast configuration on Cisco Bladecenter switches mode

  We seek to MS NLB Multicast configuration on Cisco Bladecenter switches mode. We are adding static ARP and CAM entries for each port on the switches kernel that

  the Bladecenters are connected to, or just the port of the virtual machine arrives at

  push traffic at this time here? If we add it to a single port,

  How vmotion will work... because it seems that we have to manually

  transfer the arp from one port to the other entry.

  We add the static ARP entry to the entire Cisco switch. If you can VMotion VMs NLB to another host that is physically connected to another switch, then this switch have thus added ARP entry. We have not tested the configuration only on the specified ports. But if you do, make sure that you include all the ports connected to the physical switch (if for DS you have four natachasery configured in a vSwitch...).

  Here's a guide to how we have configured it several times in our society.

• Security on the Virtual Switch

  We have a web layer and a layer of app in our environment.

  An ESX host would have a VLAN to the web layer connection and another with the application layer. Well separated and in line with our security strategy.

  We have a separate vlan for backup. Layer Web and application can share the same network card on the vlan for backup.

  Problem is that it can communicate with each other through the EPS backup because he won't have the physical switch when in the same ESX host. He speaks just internally within ESX.

  Does anyone know if there is a setting in ESX forcing traffic to go to physical swith before talking to another virtual machine on the same host?

  Hello

  See http://itknowledgeexchange.techtarget.com/virtualization-pro/how-traffic-routes-between-vms-on-esx-hosts/ for how routes traffic. If the virtual machines share the same portgroup on the same vSwitch traffic is not routed outside ESX otherwise it's almost always. Check out the blog for more details.

• SGE2010 stacking compared to the aggregation of links

  Can anyone provide an answer regarding stack switch SGE2010 against the aggregation of links if more than 1 GB connectivity is required between the individual switches? Currently, having multiple switches in a stack configuration but would like to increase the bandwidth between some or all switches. Does support cumulation a link aggregation configuration? If so the ports can be used and how the aggregation of links must be configured in conjunction with stacking?

  Hi Jacqueline,.

  On the SGE2010 - Default stacking ports: 24/GBIC 3, 48/GBIC 4 stacking support, i.e. the two ports.

  If you want a GAP between SGE2010, my suggestion, and others may disagree, would be to stop the default stacking mode and standalone mode.

  Then create a GAP between the SGE2010 switches.

• aggregation of links in the ucs servers

  Hello. Is it possible to aggregate links in the UCS Manager to get the speed of single link over 10 Gbit/s on each server? How can I do? I can build link interface on linux, which is installed on the server. But what do I do in the UCS Manager?

  Correct, the aggregation of links (port-channel) can be configured between the FI and the IOM if you have second generation FI/IOM and configure the port-channel to the title of the material > material > policies > policies > policy of chassis discovery.

  So pretty much, make you the aggregation of links at the OS level and then proceed to UCS as described above but it will provide a port channel for the entire path (IOM at the END)

• aggregation of links to the switch

  Hello

  I have a question about the next thing. Let's say you have a switch connected to the physical ESX host (or 2 for redundancy - does not matter in this case), with 2 x 1 Gbit vmnic (vmnic0, vmnic1). Now, as vswitch LB default strategy is used, it puts VMS on different vmnic automatically, and you can use the links in 2 GB of a host (of course a link to a vm etc..) But if you have conencted router switch with 1Gbit uplink, and you would like to increase link 1Gbit (router switch - & gt;) to 2 GB, so what is required on the switch (with the exception of the second Gbit active connecting to the router - blue link)? Must be configured as portchannel? And if so, then does this change require a reconfiguration side host ESX (vSwitch)?

  Thanks in advance for advice.
