• How do I know which port in the vSwitch the VM connect to?

  Hi Experts,

  How do I know which port in the vSwitch the VM connect to?

  If you have several natachasery as uplinks to your vSwitch, so you can see what physical switch your vm is attached to.  There is no direct way by ESX to see what Teddy is used by the vm if all the natachasery is active.  ESX will auto-affectation uplink based on politics, load balancing, but this information is not stored anywhere in a recoverable form.  You can always check the arp/cam/mac table on the physical switch.

• Sometimes the lost bytes, reading the serial port

  Hello!

  I'm reading the serial port data (flow rate 57600 baud rate) that works very reliable so that I do not open any other window

  or minimize/restore my window of the application during the program is running. Then a byte of incoming data will be lost.

  I get a string of 30 bytes each 50 m in most of the cases the first byte is lost, sometimes one in the middle.

  This occurs not only on a PC.

  Is this a problem of LabVIEW or Windows?

  Are there settings that can solve the problem?

  Best regards

  I solved the problem.  

  There was a bug in my program who become visible only if a window has been reduced or restored.

  When there are two or more messages in the buffer VISA, the separation of the messages was incorrect.

  Array index corresponded to false so that the first byte of the second message was at the end of the first

  and so the second message in the buffer seemed incomplete.

  In normal operation, the playback loop runs so fast, never both messages are in the buffer.

  Thanks for all replies.

  Either way, I work with LabVIEW 2009 and serial interface hardware motherboard. With XON/XOFF flow control

  is not possible in my application because all the hex values from 00 h to FFh may appear in a message.

• Use of the Trunk Ports (Cisco) on the management interface

  Hi all

  Background:

  We are in the process of consolidation of 2 farms of esx servers and will end up with 10 guests in a single cluster. Guests come from 2 VLAN separate (say 10 of VLANs and vlan 20). A test I took one of the hosts of HA/DRS and tests with it. For HA and DRS to work efficiently and properly in common all resources, we all want vm to leave both VLAN access to move to any host in the cluster.

  The test:

  My single host mentioned above, I created 2 groups of ports on a vswitch, vlan10 tag and with vlan20, I deployed a VM and tried on the two IP address ranges. It worked (with the correct settings of defined IP by VLAN) but as soon as we resources shared the port used by the management of network vmkernel port we lost the connection to the HOST from a management perspective. What the question is that it is possible to connect the management network a trunk port? We have 2 network interfaces connected to the vSwitch and both used for the VM traffic as well as management traffic. That's how they are currently implemented except that the switch port is on a VLAN-specific rather than shared resources.

  Thank you very much

  Hi Chris

  Yes, the network management also accepts the vlan tagging/trunking.

  Just add the number VLAN on the Portgroup.

  Maybe you can do a printscreen with the current configuration?

• VLANS can be configured at the vSwitch and Portgroup level?

  Dear friends,

  I hope that all do you good...

  Two statements are true about groups of ports and VLAN defined on a switch vNetwork Standard? (Choose two)

  A. A VLAN can be configured for the entire virtual switch or on groups of individual ports

  B. several groups of ports can specify the same VLAN

  C. VLAN can only be configured on individual port groups

  D. several VLANS can be specified in a port group

  VLANS can be configured at the vSwitch and Portgroup level?

  B. several groups of ports can specify the same VLAN

  C. VLAN can only be configured on individual port groups

• How does the Vswitch?

  Hello

  Suppose we have an Esxi host with 2 physical network card and a virtual machine running on it. without grouping of NETWORK cards NIC is chosen to forward traffic outside the Esxi?

  and I want to know in this scenario, how does the Vswitch? It sends the mac address-based frame? Let's say that the two network adapters is connected to the same switch.

  Thank you.

  If you don't want to use the pool (for some reason any) then creating vSwitches with only a single uplink or create multiple groups of ports on a vSwitch with multiple uplinks and override the order of failover on each port group to set vmnic active, standby and unused.

• HP DL380p G8 - packets ignored on the management port but not the virtual computer.

  I searched through discussions, but not found a request for my problem.

  We have added two new guest VM in the center of the customer data. Currently, they had 2 x DL380 of the G7 which worked perfectly for 2 years. We have added two new DL380p G8 and have some weird dropouts on the management ports. Currently using SAS-store data (no SAN or iSCSI)

  I have pre configured servers (2008 R2 on each single guest) before their move in the data center using ESXi 5.0.2 http://h18004.www1.hp.com/products/servers/software/vmware/esxi-image.html HP installation. Since we moved to the datacenter, however, the new servers to experience about 10% loss/fall of package to the management port IP, but 0 packet loss on the IP comments. It doesn't make a difference either if the management port and the vswitch are on separate NIC interfaces, same result when combined on the same network adapter.

  The Guest VM seem to work well and are not affected by the present, but any P2V we are trying to do currently fail due to loss of packets on the management port.

  Other host (DL380 G7) servers running the HP exsi distro 5.0.0 and don't suffer these questions.

  Any advice would be appreciated. I wanted going 5.1 because when I was configuring initially I wasn't aware that there was an application of conversion of VMware for him - it seems now exists, so if you think 5.1 is the answer, then I'm happy to go ahead and do it.

  I solved this problem, but thanks for all the help...

  Note for all the other people there. If you clone an esxi installation SD or USB or else save time, the MAC addresses of the server of origin met on the new server, regardless of the different physical MAC address.

  To resolve I had to run esxcfg-advcfg - s 1/Net/FollowHardwareMac on the server that had double MAC address list.  All the VMnic (4) in both servers had the same Mac as well just change the port not fix her. A new card would have solved my problem, but does not solve the problem.

  The problem was discovered running by displaying the ARP table.

• Traffic on the management ports load

  Can someone tell me what traffic is running on the management port?  I install vsphere 5.1 with 3 hosts, vmotion and san iscsi drive. I intend to separate management traffic on a closed network of 1 GB in which the management ports will connect to a 1 GB switch which will have a port connected to the global network.  Use VMotion cela this port strongly with its activities?

  The cluster will be slightly loaded with only 8 to 10 vm across all 3 four hosts of Quad Core processor.

  I intend to connect with NICs 10Gb iscsi san and dedicated switch.

  If I had to, I could use a 10G switch to the management network.

  The individual virtual machine will be nic interfaces 1 Gb individual key of the network if necessary.

  If you could tell me the documents that would also be appreceiated.

  any thoughts would be appreciated.

  Thank you

  Ken

  "Best Practice" is said to have a network card dedicated to the management, and a dedicated for vmotion. Ideally different subnets / VLAN.

  In smaller environments, but I often will create this:

  vSwitch0 with 2 network cards (if everything goes well on the cards separated/asics) and with the management and vmotion vmkernel port. It works very well, thank you very much despite sometimes described as not "best practices." Well - I think that the concern is that in situations of heavy vmotion (especially when storage vmotion is concerned) traffic management could be hampered/flooded. I just never saw him in the real world, although in environments with more than 4-5 guests I always put in place in accordance with the "best practices" just because...

  vswitch 1 with 2 maps, 2 vmkernel ports (each with its own ip address) for iSCSI

  vswitch 2 with 2 (or more) network cards and however many ports of VM / VLANS are necessary.

  (just to be clear, the 'best practice' would vswitch 0 with 2 network cards and 2 vmkernel ports that configured in the management and the other as vmotion.) Each nic will be dedicated to a vmkernel, but available failover for others...)

• Route based on the ID of the virtual Port of departure

  Hi all

  Our client uses 'Route based on originating Virtual Port ID' to balance the load. Ayone know the ESX CLI command that shows the Virtual Machine <>= vmnic in this setting?

  There was a network problem in the customer environment, and I need to know what VM is linking to what (vmnic) uplink on the vswitch about? Or ESX does not show this explicit mapping through any tool?

  Thanks in advance.

• Network management using a trunk for the connectivity port

  Hi all

  I'm currently developing a couple of hosts with a unique vswitch esx. Ideally, I would like to allocate 4 physical NICS on the host to connect to my physical network via 802. 1 q trunks. These network interface cards will then be used by some groups of ports for example vlan 10,20 and 30. I also want the Group of ports management network the vswitch using one of/all of these ports of junction for its uplink to the physical network. However, I seem to lose connectivity to the host whenever I put the port network management group vmnic to one vmnic that is attached to an uplink of trunk. If I allocate an uplink access and secure it to the management network port group I do not seem to have everything get to the problem of the host.

  I have to do something wrong as having to use a physical network adapter, mapped to a vlan access, just for hospitality management seems a bit exaggerated.

  Any advice would be greatly appreciated.

  See you soon,.

  CiscoKid

  Hello Ciscokid,

  is not a problem to achieve what you want. What VLAN id you use for the management network? You specify this number VLAN on the portgroup of management?

  Do you have any "vlan native" on the physical switch port?

• Distributed and switch the Channel ports on ESXi 4.1

  Hey all,.

  I'm trying to configure my rising for a switch distributed in ESXi 4.1 to a Cisco switch upstream. When I change the uplink group, I see that all the parameters of clustering and failover are grey. Why is this?

  What should be the protocol port of the switch upstream channel? I use LACP to my cluster equipped with Nexus. This cluster is just the integrated switch distributed Enterprise Plus.

  Hello

  The team and the failover is configured on the port group , not on the uplink group. If you select one of the groups of Port, you will notice that you can make the changes.

  Regarding the question of ports-channels, it's probably a good starting point: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1004048

  Here is another good article on this subject: http://www.vmware.com/files/pdf/virtual_networking_concepts.pdf

  There seems to be a lot of back and forth, but basically the vSwitches do not support the aggregation of dynamic link (LACP). It must be defined as static. This is where some confusion comes into play as LACP can actually support static and dynamic.

  Kind regards.

• Several physical NIC cards connected to vSwitch / Port Group

  Hello

  I have several physical NETWORK adapter on a host connected to a single vSwitch / port group, does this mean that the speed of the network is shared by all of the physical NIC, or I have to do something special to enable this feature?

  Please see attached .jpg

  Thanks in advance.

  If all of your network adapters is active in the nic teaming configuration, you must have a physical switch that supports the aggregation of links and you must configure it. The ESX itself does not have this kind of work.

  Actually is a bad idea to let all NICs connected without having to configure the nic teaming (1 active and others waiting for failover) or without going through the aggregation of links.

• 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
