With the help of VLANS and VLAN Tagging is not working / no connection

Hello

I m trying to configure a VLAN between some virtual machines on ESX host 3.

I want to do this way:

http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1004074

I got 1 dedicated NETWORK adapter to each ESX host that is connected to a dvSwitch in which I configured a portgroup

with VLAN ID 2121. I have configured each virtual machine to use this network.

When I put the virtual machines on a single host, they are able to communicate.

When they are placed on different hosts they are (if the VIRTUAL LAN is enabled on portgroup) not able to communicate.

So I m assuming it must be a problem in the config NIC on the ESX host or switch.

I m using a HP2910AL on which I activated mode trunk for each port that is connected to a NETWORK card with

the dvSwitch/Portgroup I try to use for the vlan. In the hp switch, I have a default VLAN with ID 1 where

the Ports are marked not signposted. I install a second VLAN on the switch with ID 2121 in which I scored

This tag ports.

Is there something else to do - perhaps side ESX host?

I tried changing the settings as "forged transmission-> allow ' on portgroup and I found other things

in the web, but always without success.

Kind regards

Patrick

Were you referred to this guide? :

http://CDN.ProCurve.com/training/manuals/2910-ATG-Feb09-2-VLAN.PDF

"show vlan ports" would be my next check to make sure that you have connected to your ESXi host 3 ports in the vlan 2121.

As Duncan has said if you have a VLAN ID on the portgroup in the vSwitch and you have the port on the pSwitch as trunk not acess and VLAN ID is allowed on the trunk port pSwitch you should be ok.  Just to clarify the trunk is 802. 1 q No 802.3ad.

The reverse is not VLAN ID on the portgroup vSwitch, use coelio on pSwitch with VLAN ID.  Limited pSwitch port to a VLAN, this may be ok for you?

  • With the help of text and buttons movieclips as buttons to point to the same layered framework?

    I'll have a terrible time with the 3.0 AS and animating CC 2015.2 in this project.  I was given a suggestion, but now I'm so confused output errors that I hope to get answers from you advanced people.

    The project is similar to this:

    Identify the Structure of the trees

    Framework 1 - nothing selected, visible instructions

    Frame 2 - Select sheets by clicking on the image (tree top or bottom) or text, leaves description becomes visible

    Frame 3 - branches select by clicking on the image (tree top or bottom) or text, description branches becomes visible

    Frame 4 - trunk select by clicking on the image (tree top or bottom) or text, description of trunk becomes visible


    Suggestion is:

    Do the video clip of each region of image tree and drop it on the layer smaller on top with alpha 0%

    Create a badge of the clip, and then tap on timeline with each framework has put in evidence and description

    Make the text button, then tap chronology framework with each has put in evidence and description

    Trunk frame – more small area place top layer

    Branches Frame - smaller than the leaves but superior to the place of the trunk between the two

    Framework of leaves - most square of the area on the layer under the Branches

    Can anyone offer any suggestions?  I used to program 5.5 Flash with Actionscript 2.0, but difficulties with Animate and Actionscript 3.0.  I don't know if I have to use swaps or specific images, but when viewing, he travels all frames without stopping even if each image as the AS command stop ();

    Thanks in advance!

    Yes, if your buttons or movieclips, overlap one on top Gets the default click event. So, if you decide to create separate movieClips or separate buttons, be sure to give everyone an exclusive space.

    One approach I've used in the past for such things is to open the work, the tree in Photoshop then "cut" art into segments and put each segment in a different layer in Photoshop. Then you can import that art directly in to animate and each layer will import under a separate post. Then you can combine them into a movieClip to a work of art on the stage. From there, you can select each segment and each a movieClip or button you want.

  • With the help of Rescue and Recovery to make backups of 3 different machines

    Hello, I have three laptop Thinkpad T400, X 61 and R61i. I want to back up by using an external hard drive. The HD is divided into three partitions, the smallest of X 61, the middle of R61i and most importantly - for T400. I backed up all my laptops in the appropriate partitions (base backups), but now, so I want to make partial backups, they go to the bigger partition (for the T400). Is it possible (and how) do R & R to always use the same partition for each laptop while safeguarding it?

    A few notes, to respond to your previous post:

    (1) Sysprep is used by administrators to deploy and image system to other machines. Basically, the system starts standalone RNR and save the image (drive C and the same HARD drive partitions) on the service partition.  Comment enumeration pleasure has to with additional partitions on the C drive HDD.  For sysprep to work, additional partitions must be of type Extended. The windows PE, is a windows "skimpy" PRE environment. For win7, the EP is based on Vista with a small set of win7 features added.  Thie PE is used for developers (as Lenovo) to install their systems.

    * None of this applies to a user at home like you and me *.

    (2) the logic used in the RNR for the GUI vs bent the advanced GUI are DIFFERENT.

    Example: the user has part C, D and E on C disk HARD drive.  Uses advanced parms to set backup (local) to go to E drive.

    If the backup through the advanced graphical interface, drive E is honored.

    If the backup is performed through simple GUI, the partition with the largest free space is used.

    Note: using the Second HARD drive don't offer NO choice to designate a partition target of \RRbackups.

    (3) view of backups.  It's clearly too.

    When a backup is performed, and RNR is locked on him, it will REFRESH the registry entries for the content of backup.dats in the \rrbackups folder. Subsequent backups of view will probably be read from the registry. That is to say no record of reloading. Simpified mistletoe might once again, just to use the registry, the locks of GUI in the new backup folder.

    (4) your letter removal/restoration

    a: I have no idea how autonomous RNR will react to the 3 folders on the second \rrbackup, IE the part 1, 2, 3.

    b. If rnr backups locked in the wrong \rrbackup folder, you will have a total mess. A symptom of this: you take a basic (full) backup, and the next backup, which should be an incremental, is actually another full backup.  This error could occur if you deleted the wrong letters.

    (5) you have a mess.

    If I save it again this PC, R & R is a point instead of a differential backup<>

    It would take a lot of work on you end to look in the backup files.  Not worth it.

    Again, the simpifed GUI backup use different logic. He likes the larger partition.

    From what you say, you used simplified and got the base of the machine backup 3 all go good part 1, 2, 3.

    Somewhere in this mess, he locked in a \rrbackups without a base backup folder and took another backup.

    who knows.

    ==

    Release notes:

    Review 4
    ----------------
    Location of backup changes when you select a smaller partition through the advanced interface of the Rescue and Recovery program.

    In the advanced interface of the Rescue and Recovery program, you select a partition more small capacity on your local hard drive as the backup location. Then, you switch to the simplified interface to create the backup. However, the backup is created on the partition with the highest capacity.

    To resolve this problem, back up your system in the advanced interface of the Rescue and Recovery program after you have selected the backup location.

    The solution is the cleanest way to follow. I would always use the GUI advanced for now on.

  • With the help of Vlan for LAN and DMZ

    Hello

    For the moment, I have assigned my LAN and DMZ networks to two separate network card (so therefore no Vlan tagging)

    for example vmnic0 = LAN, vmnic1 = DMZ.

    It works well but I like to make changes in the way I want to use two separate physical network adapter and use on the two s two LAN and DMZ nic but now using the VLAN.

    So think of this configuration:

    For each network, I create a Vswitch, in order to obtain a Vswitch named VsLAN, VsDMZ for the case.

    The Vswitch I attribute a two nic Nic will be the day before. as vmnic0, vmnic2 (at rest)

    This Vswitch I create a port group and assign the correct number of VLan as LAN 10 and 20 to the DMZ.

    Create the another Vswitch will have the same Nic but now vmnic0 will be the stanby one.

    Probalby all great so far I think or not?

    Issues related to the:

    -Well this concept where there is a relationship a Vswitch and port group or a switch with multiple exchanges?

    In case a Vswitch with multiple port groups I will assign to group level reserve and the active NIC Port.

    -If I create a group of ports and assiging several Vlan IP packets received by the virtual machine itself also be labelled or not identified?

    Other words. Do I need to configure the NETWORK adapter to the virtual machine also for the same local network ID virtual or not.

    Thanks for your comments.

    Hello

    Change of vlan is a pretty good idea to get the failover and the performance of the network LAN and DMZ. You have confused somewhat however concepts.

    A can only be used in a vSwitch vmnic. So what you want to do is the following:

    Create a vSwitch

    On the vSwitch create two ports: LAN (vlan10), DMZ (vlan20)

    If vmnic0 and vmnic1 have access to the vlan10 and 20, then simply add the two vmnic virtual switch. By default, they will both be active and that's fine. If you do not want to CHANGE the GRPE ports LAN and goto the "failover" tab and put vmnic0 as active and vmnic1 as before. Then do the reverse on the DMZ port group.

  • LR 5 questions with the help of sorting and spot removal tool

    LR 5...  Same problems with the sorting, WinX 64... crashes.  Delay of about 5 seconds to select a thumbnail, if I click on one and it lag I can fly over another and he will choose the other.  He refuses to move files selected at least 3 attempts.  However, it doesn't seem to work better work out thumbnails of Strip below.  When it starts acting up a restart does not help.  Also there is a huge gap and the jumpy mouse pointer when you use the removal tool / clone spot.

    I only LR open so the computer overload is not the issue.  I Suite OnOne 7 also and ANDLr, also many other programs open and this program works perfectly.
    I have not had any problems with the LR 4 but LR 5 is a great advertisement of NOT getting a new version until the bugs are removed.  It drives me crazy, so go back to LR 4.  The tools in LR 5 but not the accidents of love.

    These are the few that I've met so am not treats using the version 5 There is no update as of July 18, 2013 so any suggestions using LR 4 or go for a long walk until these issues are addressed?  I'm annoyed say the least to upgrade and then get grounded when I have a load of work that is time based!

  • With the help of ESXi and vCenter

    Hi all, I have some doubts on the use of ESXi and Virtual Center.

    Recently, we have set up 2 servers ESX with Virtual Center, all allowed in the Standard edition to have an available shared storage and HA.

    Our idea is to set up a new server with ESXi installed for testing purposes.

    Is possible to manage this server ESXi with our real VirtualCenter or we need a license? This particular server does NOT use shared storage or HA.

    Thanks for your help!

    Kind regards

    Yes, you need a license for ESXi manage VirtualCenter. You can purchase the license to the Foundation. Please see the license attached (on page 3)

  • [Issue] [CS5] With the help of. send() and some other questions

    Hi guys in these last days I made research Stratus in CS5 hoping to be able to reproduce some kind of multiplayer game of him. The main problem that I ran in use. send(), I can't understand how to use the correctly. This is what I understood would work, but it doesn't seem to register that something happened:

    var myString:String;

    function sendmsg(2) (event: MouseEvent): void
    {
    myString = textInput.text;
    outgoingStream.send ("msg", myString);
    }

    function msg (myMsg:String): void

    {

    myLog.text += myMsg;

    }

    Any help to do this would be greatly appreciated.

    Just a few small questions about Stratus I want good answer:

    1. Use. more faster/more efficient send() then post where a fraction of a second account (sending players positions) where there are 4-8 people?
    2. When you use a NetStream with an attached how GroupSpecifier know when a person has joined or left?

    Note: All questions are regarding the CS5, not Flash Builder as I am not very aware if there is any difference in coding.

    NetStream.send () should generally be faster than NetGroup.post (), especially when using NetStreams 1:1 (vs. Group NetStreams).

    When groups are great, there is no average liabilities to say when members join or leave.  However, for small groups (less than 15 members), they will be "full mesh", meaning that each Member is a direct connection to every other Member.  When this is the case, you can see the events of NetGroup.Neighbor.Connect/Disconnect on a NetGroup.  to receive people, you create a network group with the same groupspec than your NetStream and listen for events from NetStatusEvent.NET_STATUS.

    your "msg" function must be a method on the 'customer' object of the NetStream subscribed to receive the NetStream.send (s) of the editor.

    It's all generic ActionScript stuff.  I don't know how to use Flash CS5, but such things should all be the same in Flash and Flash Builder.

  • With the help of sysdate and systimestamp etc. in ViewCriteria

    Hello

    I have a VO based analytic query that performs some stacks based on time.

    This table based VO, for example 'all items sold 10 days ago 4 days ago' County, now open a search page. Which will be displayed exactly all items sold in this time.

    In a first part of the soln to achieve, I started and created Scvs for the different periods I have. For the field soldDate (timestamp), I created a condition using the clause "between (soldDate between to_timestamp(sysdate-10) and to_timestamp(sysdate-4)). But I realized that it does not work. I used the link variable and the option "expression" instead of "literal" for the value of bind variables and the VO test throws an exception. Of course, he does not expect these constructions.

    QTS is how I could accomplish this kind of condition to be applied to a VC.

    I know that I put as a sql string and add to the place where clause. A VC based soln is possible.

    I use version 11.1.x.x.x of Jdev and not 12 c .x

  • With the help of local and remote servers

    Can someone point me to somewhere that explains the use of servers the remote and? I have set up a local server (using XAMPP) and also a site remote dev on my hosting server. I'm assuming that I can choose to download files on the local or remote as I wish (local test and publish remotely). Is this the case? Currently, I can't download files on the remote server. When I "put", the files just to go to the location of the test (localhost).

    Any ideas?

    You test locally on XAMPP (or similar) and when ready, download on your remote server. If using could not upload to the remote server, it means that you have not set the remote info in your site definition.

    The only thing you can not download through Put is the database. You must create a database with the same name on your remote server. If you have data that you want to download, you can use phpMyAdmin to export to a .sql file. Then use your remote version of phpMyAdmin to import the data by accessing the file .sql on your local hard drive.
