SG500 showing the same MAC address on more than one port?

My ISP has been help me solve a problem that we had with an interaction between our SG500 battery on HP customer premises equipment.

I have the stack of SG500 divided into two VIRTUAL LANs. 8-port VLAN11 and the rest on VLAN1. Both are of VLAN native, not marked so they will carry only the traffic for their own VLAN with no mixing. I also route between these VLANs on the stack.

VLAN11 switch ip: 10.76.20.20

IP switch VLAN1: 10.1.1.1

I took a port for each VLAN and plugged into the HP PSI switch, where he adapt VLANS separated which then connect to a remote data center through an MPLS.

Here's the question: the SG500 seems to have mac address base on two HP PSI switch ports. This disrupts the HP switch, and I end up having packets to fall into a black hole. This is the output of the switch from HP showing mac based battery SG500 goods between ports in seconds:

HP # display the address mac 8843e1-af7085

Status and counters - Address-Table - 8843e1-af7085

MAC address: 8843e1-af7085

Located on the Port: 15

HP # display the address mac 8843e1-af7085

Status and counters - Address-Table - 8843e1-af7085

MAC address: 8843e1-af7085
Located on the Port: 11

Any idea what's going on here? It's as if the SG500 uses the MAC even for both its IP addresses.

Thank you!

Hi Dani, the only MAC address announced by SX300/500 series should be the Mac system if you show on the SX500 mac address table, you should see the MAC even for both VLAN. I don't know why, is to confuse the HP switch unless it does not correctly between switches vlan tag.

  • exit show me the same MAC address twice

    Hi all

    and easy for sure. When I run the interfaces see the G0/1 command on switch, why the output shows me the same MAC address twice?

    the address is 00d0.58c0.4519 (bia 00d0.58c0.4519)

    I know, BIA is burned in address and is located on the ROM, but what is the idea behind this?

    EDIT: also would like to ask, why a router maintains an arp entry for its own interface, it seems that this is not the case on for example a Windows laptop...

    Best regards

    Adam

    Adam,

    Some interfaces allow you to configure user-defined MAC address:

     R1#show int f0/0 | i bia Hardware is AmdFE, address is cc00.0fac.0000 (bia cc00.0fac.0000) R1#conf t Enter configuration commands, one per line. End with CNTL/Z. R1(config)#int f0/0 R1(config-if)#mac-address 0200.0000.0001 R1(config-if)#do show int f0/0 | i bia Hardware is AmdFE, address is 0200.0000.0001 (bia cc00.0fac.0000)

  • repeating subforms can you script to stop the same value being selected more than once

    I have a LiveCycle form with a subform that is repeated when the first field (text field 2 characters) requires the entry of a code between 01 and 99. You can script so that you cannot enter the same value of code more than once?

    Here's a code in Formcalc that works for you. Put it in the output of the textfield event.

    In this example, the page is called myPage and textField is called TextField1. Rename them as you need.

    indexCount var = 0

    var thisIndex = $. parent.index

    While (indexCount< thisindex)="">

    If (myPage [indexCount]. TextField1 is myPage [thisIndex]. TextField1) then

    xfa.host.messageBox ("you already used this number")

    $ = ""

    endif

    indexCount = indexCount + 1

    endwhile

  • Header record not repeated when the detail records extend to more than one page

    Model RTF,

    1. I have one for each code of

    <? for-each@section:G_HEADER? >

    2. under "for-each", I have the header of the document is set in a row of the 1 table.

    The row for this table property is set to 'Repeat as header at the top of every page'

    3 in this, I have another table with the fields for data LINES with its own code "for-each" <? for each: G_LINES? >

    4. follow-up of the end for the two above "for-each".

    However, when I generate the PDF output in overview, data lines extend to more than one page, the header record is not repeated on the following pages. Anyone has any ideas of how to solve this

    My version of the XML Editor is 10.1.3.4.1 build 130. I have an example of data and model, but don't know if I can download it here.

    Use this logic


    INFORMATION HEADER TABLE

    DETAIL TABLE

    and keep this in the header then it is displayed even though the detail data go to more than 1 page.

  • How to leave the input field to accept more than one "specific" response

    Hello

    I work for something and try to create a game show type-box-based for one of my classes, where a text entry field can change that is the border color if 2 or more words from a list of recognized words is registration.

    For example, a list of possible answers a: R, G, B, Y to the question "name 2 colors»

    I want to create an input text area where the border of the box changes color if the 2 letters (in the list above) are entered in it.

    I tried implementing a variable NumberSuccesses and set so that the number increases by 1 for each letter entered for example

    If (Ex.text is "R");

    NumSuc = NumSuc + 1; var NumSuc has already been previously defined in the code

    If (Ex.text 'G')

    NumSuc = NumSuc + 1

    If (NumSuc == 2)

    Ex.borderColor = 0x0000FF

    but it does not work... and I tried to do it with another function which I use for several text boxes as if there are boxes A, B, C. I could set up a general function where if the correct answers were entered into A, B, C respectively, only then will say, a check mark appears by using a

    EnableCheckmark (); function of type. Don't know how to do if it is the same text entry box well. Also just tried adding in the same function re.

    If (Ex.text is 'R' + 'G')

    Ex.borderColor = 0x0000FF

    .. Does anyone know what I can do?

    The solution of Mathias with the logic of the evaluation:

    What are the possible answers

    var solutions: Array = new Array ("A", "B", "C", "D");

    function testInput(_inputText:String):Boolean

    {

    the delimiter could also be a comma, it's here a space

    var inputStringArray:Array = _inputText.split("");

    var counter: Number = 0;

    for (var i: int = 0; i

    {

    for (var j: int = 0; j

    {

    If (inputStringArray [i] is [j] solutions)

    {

    counter ++;

    }

    }

    }

    If (counter > = 2)

    {

    trace ("true");

    Returns true;

    }

    on the other

    {

    trace ("false");

    Returns false;

    }

    }

    TextField with the name input_txt onstage

    input_txt.addEventListener (TextEvent.TEXT_INPUT, answerTxtInp);

    The function that will be called by the event listener

    function answerTxtInp(txtEvent:TextEvent):void

    {

    According to the responses of characters, change the color of the border

    {if (testInput (input_txt. Text))}

    input_txt. BorderColor = 0xFF0000;

    }

    else {}

    input_txt. BorderColor = 0 x 000000;

  • With the help of CC on more than one Machine

    Hi guys

    Sorry if this is an obvious question. I have CC on a PC and laptop. I understand that I can only use it on two machines at once (although it can be charged additionally). However, I am away from home and I just acquired another laptop. Can I load CC on this machine as well? The home PC is not running. But is that enough to allow me to charge CC on this 3rd machine I connect physically as the PC at home from my account?

    Kind regards

    Graham

    You can install your cc on your new desktop computer application.

    trying to connect by using a computer 3rd you are given the option of disconnecting from the other two computers (from your 3rd computer).  could not be easier.

  • Syntax to assign more than one port?

    Hi all

    Appreciate all help I have on this forum.

    Is there a way to use and the command access-list and eq 5000 to 5020 ports on a single line? I tried... eq 5000-5020 without success.

    TIA,

    HI -.

    Yes you can do this by using "range" instead of "eq" i.e.

  • same mac address lan on different esx hosts

    Hi, I have a unit of vmware (firewall) who take control of the NICs mac address, if I move this to another Esx VM, all configuration fell, because the lan mac address is different from the first Esx.

    Is there a way to put the same mac address on two or more Esx host in the network adapters.

    I tryied to set the mac address on the settings of the VM manually from the second Esx, but the first part is blocked.

    In this case, I suggest to make a manual copy.

    Or remove the inventory on the destination hosts, set the vmx file (to restore the old MAC address), then add back to the inventory.

  • When issuing vNIC with the same MAC on the same vSwitch

    Hi all

    In a public cloud computing environment, only host hypervisor (VMWare ESXi for example) can host VMs of different customers. These virtual machines can use the same MAC address for the vNIC. What happens if these virtual machines with the same MAC connected to the same vSwitch by chance? This will cause the MAC table on the vSwitch updated constantly which would lead in turn to the performance problem.

    How vSwitch or what type of solution could solve this kind of issue and provide a network environment isolated to each cloud tanent?

    Thank you!

    It would be on the cloud provider (who generally do not use vSphere anyway) to mitigate.

    If you are a supplier, you can use something like vCloud to isolate your environment shared with the support of as vShield products and technologies such as VXLAN.

  • Meet multiple IFs with the same MAC, why limited?

    Hello

    I'm currently testing a configuration with a controlled 802.3ad bundle a Linux guest and an external switch via 2 vNIC / hnics.

    Each vnic is in a group of different bridge, so I assume that the workstation should not have any problem with both receiving the same MAC address, but it does.

    Is there a magic wand shot to disable this check? Or what is there is only one table mac address in the vswitch so it won't work?
