In vCenter, standard vSwitch displays duplicate network connections

• vCenter standard vSwitch trade + different VIRTUAL local network settings

  Hello

  In vCenter Standard vSwitches, vCenter allows, the same standard name exchanges on different ESX hosts on different VLANS. It is considered to be a bad configuration? Or is it not seen? (Or better yet, can there be real use cases?) Because eventually the traffic would not pass by with this configuration of vlan different, even if the exchanges have the same name for them.

  For example:

  ESX1 - vswitch1 - MYportgroup (vlan5)

  ESX2 - vswitch2 - MYportgroup (vlan10)

  In distributed vSwitches, we have this problem, since it will be a unique portgroup for all the esx servers.

  Thanks in advance for anyone who can shed light on this issue.

  Certainly a use case of vDS in a production system, where this problem would not be a problem. Think about it, however, there might be something useful in a test environment, where you may need to test the configurations or to connect to different parts of the network on a machine virtual 'utility '... If NIC of the virtual machine is configured to use DHCP, the IP configuration could be changed automatically when it moves on different VLANS, etc... It might be useful when you have a network configuration where you had to plug some VLAN specific to specific hosts. Then by simply vMotioning fast virtual machine to another host, you can dynamically change its location on the network.

  Certainly, I would say that it is not a best practice for a production environment, although...

• Safari displays "the network connection has been lost" for all files flv on the internet.  Firefox reads all

  I've upgraded to the latest version of Flash to correct what I thought was a problem in Firefox.  This problem turned out to be something else but now Safari will not play ANY flash content.  I uninstalled and reinstalled several times.  I even installed an earlier version.  All the these have exactly the same result.  Flash works in Firefox, but not in Safari.  I cleared the cache.  I entered the settings of flash securty and remove all the content.  Nothing seems to change this.  Anyone have any ideas?

  Never mind.  Stupid stupid stupid.  There was a firewall rule blocks flash.  I don't know why it worked in Firefox but when I unchecked, fixed it.

• Network connections not recognised on IBM T43 laptop with XP

  A few years ago, I bought a refurbished IBM T43 laptop with XP. It worked well, but eventually became slower and slower over the internet. I replaced it with another new laptop and trying to get the old work by reloading XP. The wireless connection and direct connection are not recognized by the display of 'network connections '. They have both worked, although very slowly, before reloading the XP software. Where can I go from here?

• After reformatting XP, my computer does not display my Ethernet/network connection

  I reformatted and reinstalled XP, service pack 2.  Device Manager does not display a network, nor the fact reckognize my ethernet connection.  I have a Linksys router.  To install it, I have to be on the internet.  I can't be on the internet without an ethernet connection.  How can I fix it?

  Hello

  I feel when you go into Device Manager there is a yellow question mark. If you expand this section you may find an unknown device. This will be your network card. So basically, you need to know what brand and model of the network adapter is. Download the driver from the internet on another computer. Then install it on this one. The unknown device will then pass under the network connection in Device Manager.

  So basically, you will need to download your ethernet card driver.

  I hope that people who have this problem in the future, you read this before you follow Ricky RockStars because he has mental health problems. After having seen his reply here and then others and it is how wildly incorrect, I did some research. I saw one of his messages on a forum from another site where he calls himself, "master of puppets" and he said he finds his answers on google. Dell isn't the only place to take responses at random to see if a stick, said. Apparently, he did that on ' yah * answers "and others, also. It is not a true expert, and instead of saying that he doesn't know, he barks just the random directions to try to solve problems or problems which can still be fixed, as it did here. He loves the power of the people who listen to him. He really has no idea what she's doing. He just googles your problem and tells you what it finds, as if he knew. The problem with is that if you have already done this, he will find the same wrong information makes you or even worse information as he did here. I saw a lot of his answers and about half are correct, 1/3 are wrong and just wasting peoples time, and the other 1/6 are harmful. Look at what happened here. He should have just said what I say below, but instead of that he had a back and forth for days because he loves control.  Seriously, I don't understand how Dell allows this to happen. It is everywhere in their forums, which gives bad advice, and using people as the 'puppets' in his weird game to control the actions of others.

  Here's the real answer:

  Dell Vostro 3550 does not support WiFi 5 Ghz network connections. There is nothing you can do to address this problem in addition to changing the hardware (go out and buy a 5 GHz USB adapter).

• No network connection between the virtual machines on different hosts ESXi

  I have several 5.0 ESXi hosts in a cluster managed by vCenter Server 5 and I have network problems:

  1. [Host A] running a virtual machine can ping any other computer virtual running on the [host A] great!
  2. A virtual machine running on host [B] can ping any other virtual machine running on [B] home - very well!
  3. [host A] (from the ESXi console) can ping any virtual machine running on [B] home - even better!
  4. [B] home (from the ESXi console) can ping any virtual machine running [host A] - beautiful set!
  5. A virtual machine running [host A] can not ping any virtual computer running on host [B] and vice versa - bad, very bad!

  So basically the problem is that the virtual machines can communicate on hosts. It is a major problem that I need to fix, for obvious reasons.

  Networking on all hosts is configured exactly the same way: a unique and standard vSwitch with a pair of gigabit network cards grouped, vmkernels configured for the vMotion, NFS and network management and a group of ports configured for the VIRTUAL local area network used by the VMs. (vMotion works fine on hosts, storage vMotion works very well too.) All virtual machines are servers Windows (2003 and 2008).

  Reason #3 and #4 above, my assumption is that #5 must be the result of an ESXi/vCenter configuration issue and not a problem with the switches of material upstream. Is this a reasonable assumption?

  Whatever it is, can anyone offer suggestions on how can I fix? It is quite annoying as I'm pretty sure that these hosts are configured in the same manner as those of our production cluster, which does not at all these problems!

  Thanks in advance for any help you guys can provide.

  To be honest, it looks like a problem with your physical network-

  How is the physical network configured - are NIC connects it to the same physical switches? Are the virtual machines on the same subnet? If this is not the case, they are able to ping the gateway sbnet? Can you piing host IP address from the virtual machines?

  I also moved it to a forum more approiate.

• Problems of EA3500 of 5 GHz network connection

  I'm having difficulties to connect to our network of 5 GHz. When I open the list of available networks on my laptop (new windows 10 Toshiba) and Iphone(5s) only our 2.4 GHz standard is displayed. Although on the app of router, I noticed that my laptop of brothers and sisters is connected to the 5 GHz network.

  The name of the network 2.4 and 5 GHz are exactly the same. When I changed names to differentiate between networks, devices have been disconnected from the Internet and I couldn't return until I changed the name back.

  If you have any questions to my aid situation please ask, I will answer you shortly.

  Thank you

  You did while differentiating between the 2.4 Ghz and 5 GHz SSIDS. This will make the resolution of the problems. Simply reconnect the devices for the new SSID and you should also bring to forget the previous SSID.

• Cisco UCS C210M2-VCD2 network connectivity

  Hello

  I will install three servers of c210M2 and I am quite new to the world of the UCS. According to the design that I'm supposed to install

  4 x Vm (CUCM, CUC, presence, UCCX) primary or Publisher on NGC 01

  4 x Vm (CUCM, CUC, presence, UCCX) subscribed or failover on NGC 02

  2 x Vm (MeetingPlace) on NGC 03

  I have a few switches access X 3750 for network connectivity. My question is how to configure the NICs on UCS Server or the network. According to my knowledge each server has cards NIC 2 x 10 giga and 1 x NIC integrated management. I'm confused how many NICs each VM will have and how to set up all these VMs NIC on 2 x card physical NETWORK by UCS. Any suggestions please.

  Kind regards

  Asif

  Asif,

  Nexus 1000 would be useful here, but if not an option and that you use standard vSwitch then both NICS should serve rising in a unique vSwitch for redundancy.

  Here are some suggestions of QoS that might help you too.

  Rredundant of the physical LAN interfaces are recommended

  One or two pairs of cluster NETWORK adapter for the CPU VM traffic. A pair just on C210 due to the low load per VM

  A pair of NIC (or dedicated team) for specific traffic VMware (mgmt, vMotion, VMware HA, etc.)

  SIDENOTE: Pair of grouping NIC can be divided through the motherboard and the PCIe card permitting the UCS C-series, protects against the failure of the PCIe card

  Once we know exactly asked what vSwitch using as the last post, we are able to locate more, but this is based on the standard use of vSwitch

  I hope this helps.

• Network connectivity lost every 24 hours after the migration of DVS

  Hello community...  Well, I'm puzzled again.  I am running a vSphere 5.5 U3 environment with the latest patch.  I'm going through certification VCP - VTC prep and decided to migrate my (lab at home) environment of standard virtual switches to virtual switches distributed as I have not had a lot of experience with them so far.  Migration seems to be okay.  Before migrating, I used three different 1 Gbit/s links a group of hash LACP-IP on my standard vSwitch.  I have several VLANs for different laboratory networks.  One is specifically used as a DMZ for the WAN to my ISP connectivity.  I created a virtual machine for use as a firewall with multiple network cards, which one is connected to this VLAN WAN.  On the standard vSwitch seemed to work exactly as expected.  For some reason any after moving to a DVS, the firewall VM needs to be recharged all morning before the full network connectivity is restored.  It's a strange problem.  I tried to re - create the virtual machine and play with the security settings of DvPortgroup, but the problem persists.  Anyone out there have any ideas as to what could cause this?

  Oh, a little more in detail...  I moved from hash balancing LACP/IP road based on the physical NIC load with the migration to DVS.  Remove groups from the aggregation of connection of the switch too.

  Well, change of load balancing policy and upgrade the DvSwitch to version 6 did not help.  However, I stopped the machine virtual and added 4 E1000 NIC as a test.  I've reconfigured the firewall VM to use the new cards instead of the VMXNET3.  Load Balancing has changed back to "load depending on the physical NETWORK card" and always use VGT to separate traffic.  From now on, he went the longest without experiencing the issue so far.  About 16 hours so far without having to restart the virtual machine.  Will keep posted guys.
