P2p self-looped VLAN

I have a single trunk on a 3560 connected to a Juniper EX4500 running PVST and the switch is also the root bridge as another 3560 on another port is also connected via a single trunk, both ports are fibre connected, one MM and one SM.
The port to the Juniper, g0/26, has 8 VLANs running through it of which 2 of them are in a P2p self-looped state.  All physical links out of this switch are single links.  There is two ESX hosts but no port-channels only individual trunk links, there are two port-channels to a NetApp SAN with two ports per channel.
On the Juniper I run MSTP but block it at the port level that connects to the Cisco.  I've checked all physical cabling to ensure no loops, also checked the other 3560 just in case.  I have rebooted the switch as well.  The fibre link used has also been changed as there is a 12core fibre between the two locations linking the 3560's.  I haven't moved the SFP to a spare port yet to see if it is a port issue however.
The port to the other 3560 is g0/25.
This is the output of show spanning-tree interface g0/26:
VLAN0001            Desg FWD 4         128.26   P2p
VLAN0006            Desg FWD 4         128.26   P2p
VLAN0010            Desg BLK 4         128.26   P2p self-looped
VLAN0032            Desg FWD 4         128.26   P2p
VLAN0034            Desg BLK 4         128.26   P2p self-looped
VLAN0036            Desg FWD 4         128.26   P2p
VLAN0043            Desg FWD 4         128.26   P2p
VLAN0192            Desg FWD 4         128.26   P2p
I've also looked for other possible devices that may cause this but haven't disconnected either the ESX hosts or NetApp SAN ports, even individual links in case they are the cause.
It started 2 months ago, luckily there is other networks available and the networks having the issue only service one individual however the voice network is affected, vlan0010.

  • How oracle spatial deals with self-looping polylines?

    Hi,folks
    I have a general question on self-looping polylines.
    If one polyline is self-closing, can oracle spatial recognize it as a line or polygon?
    Anyone can give some hints on that?

    HI!
    Review this page:
    http://download-west.oracle.com/docs/cd/A91202_01/901_doc/appdev.901/a88805/sdo_intr.htm#877625
    They say that "Self-crossing polygons are not supported, although self-crossing line strings ARE supported. If a line string crosses itself, it does not become a polygon. A self-crossing line string does not have any implied interior."
    Also, line strings are defined with their own SDO_GTYPE, such as "DL06" for MULTILINE or MULTICURVE, where POLYGON is "DL03" and MULTIPOLYGON is "DL07", so they can't be confused one with another.(See http://download-west.oracle.com/docs/cd/A91202_01/901_doc/appdev.901/a88805/sdo_objr.htm#1005537)

  • Autonomous Updating of Web View slides for Self-Looping

    We just bought an 20" iMac with the purpose of hanging on the wall as a hallway display. I'm making a Keynote 2 application with most of the slides being generated using the Web View images.
    I've got my presentation set up as a Automatically play at Startup, loops and is Self-Playing. I'm curious if anyone has figured out a way to set up the presentation so the Web View pages update automatically while in presentation mode. I know if you stop the presentation and restart it, the slides will update, but I'd like it to update while it is playing, so I can just let the presentation run 24/7 and update the pages on the fly.
    Thanks in advance for any help!

    I tried playing around with AppleScript, saving the AppleScript as an application and entering it into cron. It works about the first couple of times, then about the third time cron is run, it doesn't restart Keynote. It assumes Keynote is already running and playing the slideshow when the script is called.
    Here's a copy of the AppleScript:
    tell application "Keynote"
         stop slideshow
         quit
    end tell
    tell application "Finder"
         activate
         select window of desktop
         open document file "iMacBriefing2.key" of folder "Desktop" of folder "amm" of folder "Users" of startup disk
    end tell

  • Is it better to use router port versus vlan member port?

    Hi CSC,
    This is more of a philosophical or "best practices" question.
    I have a Cisco 3550 at the home office. Connected to the 3550 is a number of branch offices by way of T1 circuits or VDSL modems. They all come to the home office, where we have a central internet connection and server farm for our entire organization.
    Except for one special case branch office, we don't forsee the need for appearances of the  home office vlan at the branch office sites. In that case, we bring it  into a trunk port at the home office, and at the special case branch office we have a dell 3024  switch and tag some ports as vlan 18 (the home office) or vlan 27 (the  special case branch office).
    We also do not forsee a need for the vlan from one branch office to appear at another branch office.
    They are all (except for the special case mentioned above) currently configured something like this:
    interface FastEthernet0/1
    description home office
    switchport access vlan 18
    switchport mode access
    interface FastEthernet0/2
    description t1 to branch office 1
    switchport access vlan 19
    switchport mode access
    interface Vlan18
    description subnet for home office
    ip address 192.168.18.1 255.255.255.0
    interface Vlan19
    description subnet for branch office 1
    ip address 192.168.19.1 255.255.255.0
    Is it better, in terms of reduced network complexity or performance on my 3550, to do something like this instead?
    That is, to make the interfaces router ports as opposed to vlan member ports?
    Of course, if we ever DID need to have appearances of the home office vlan at branch office sites, or appearances of one branch office's vlan at another branch office, we would lose that flexibility.
    interface FastEthernet0/1
    description home office
    switchport access vlan 18
      switchport mode access
    interface FastEthernet0/2
    description t1 to branch office 1
    ip address 192.168.19.1 255.255.255.0
    interface Vlan18
    description subnet for home office
    ip address 192.168.18.1 255.255.255.0
    no vlan 19

    Hello,
    In my opinion there is no 100% right answer here. I think it depends also about network forecast. I'll try to add here some thoughts:
    - if you use trunk interfaces from home to branch and SVI for L3 connection, in terms of scalability is much easier to expand (you have now only one p2p L3 link, but in future you'll need another one; if the port is a trunk one, you just configure another SVI interface, allow vlan on trunk and your good to go)
    - trunk interfaces involve more configuration (L2 interface and SVI L3 interface)
    - if you add in the home office another switch to existing one, and for some reason you have misconfiguration in STP / VTP, then you can run into problems like loops, vlan database modification (e.g. VTP server mode and the new added switch has a higher revision number than existing one)
    - L3 physical interfaces are easier to configure and less complex, but in case you want to scale to additional p2p link will be harder
    - L3 configuration is easier to troubleshoot as you avoid the L2 complexity
    - in terms of packet exchange a L3 interface will exchange less packets than a L2 trunk with SVI (I'm talking here about control traffic, not user traffic)
    - with L2 trunk you can have other problems like if somebody is "smart enough" to add a new switch into the existing switch (if you have a switch there) at the branch location; imagine that the new switch due to misconfigurated STP became root bridge; you have a large STP domain.
    As I said, there is no good or bad approach. You have to guide yourself about forecasts in your network. For example if you know that a branch location will not be extended in the next 2 years, then go ahead with L3 interface and that's it. On the other hands if you have doubts you can add for another location L2 trunk with SVI. You can mix this two solution to obtain the best results for your network characteristics.
    Cheers,

  • URGENT: Full Time Loop: Multiple QT Files with Video

    Hi,
    I have a presentation that contains only 1 slide.
    Contents:
    Video-movie: 2 min.
    3 QT files on a loop.
    Question:
    How do I have the QT files loop for the entire 2 minutes of the video?
    THIS IS URGENT; I NEED TO PRESENT THIS AT 7PM TONIGHT.
    THANKS.

    Hi,
    This is what i have:
    2 minute video
    3 self-looping QT files
    I want all 4 files to play simultaneously during the entire 2 minutes.
    You are certain that QT Pro allows to set these parameters?
    Where would I go within QT Pro?

  • Delta between DSO and Cube

    Hi All,
    I have been working on a scenario where in we have to realign org structure information of some sales orders , now we have existing sales orders data in DSO , which feeds to a cube . As part of the realignment some master data attributes, more specifically Customer Master attributes,  will be changed in R3 for those Sales Orders.
    These attributes are part of the transaction data load which is happening to the DSO from the source, now since this transaction load is taking time, to speed up the process of realignment in BW I have used a routine to lookup the masterdata attributes from 0CUSTOMER in BW.
    so before BW pulls the realigned data ( Sales Orders ) from R3, I will run a self loop in the DSO where in it will do a lookup in the 0CUSTOMER master data in BW to get the updated customer attributes (ofcourse the 0CUSTOMER load will happen before we do any realignment of the source data) .
    Once the self loop transformation is completed and the sales orders are updated with the updated customer attributes, I will load the data to the cubes. (delta load)
    Now once the sales order realignment is finished in R3 , I will pull the same set of data in the DSO .
    Now the question is, is it necessary that I do a reinit of the cube before I load the second set of data to the cube?
    I guess it is not necessary.
    Please share your thoughts.

    Hello Partho
    I understand your KF are overwrite in DSO. But in BI7 flow delta from DSO to cube is request based.
    When you will do a self-loop, same records ( I guess you have already loaded them to cube) will have different request id.
    As a result your Change Log table will get different id after activation. So same record will get loaded to cube and which will make all your KF in cube doubled.
    I believe to make correction in historical records in cube either you have to delete cube content and then run delta from DSO to cube.  As first time delta will read Active table of DSO you will get all KF correct in cube..
         Else, you have to delete all those previously loaded record from cube selectively.

I also goet some weird not serialized exceptions before on some other classes that are not being written to the file or are not part of the object that I am writing. I serialized those classes and now it's this unknown object that's causing problems.
    Edit: The problem may be due to the JFileChooser I am using to select the file as it is a non-serializable object. But I am not trying to write it to the file and in fact am just writing the arrayLists and BigInteger as objects to the file.

    java.io.NotSerializableException: javax.swing.plaf.metal.MetalFileChooserUIThat's a Swing component and it is clearly related to the JFileChooser.
    I also get some weird not serialized exceptions before on some other classes that are not being written to the file or are not part of the object that I am writing.That's a contradiction in terms. If you get NotSerialzableException it means the objects are being written. So they are reachable from the objects you're writing.
    Edit: The problem may be due to the JFileChooser I am using to select the file as it is a non-serializable object.JFileChooser implements Serializable, but you're right, you shouldn't try to serialize it. But clearly this is the current problem. Somewhere you have a reference to it reachable via the object(s) you are serializing.
    I suspect that Node and Edge inner classes and that you aren't aware that inner classes contain a hidden reference to their containing class. The solution for serializaition purposes is to make them static nested classes, or outer classes.

  • Using cue points to acrivate movie clips

    I'm trying to write a simple piece of ActionScript that I can
    adapt and re-use easily. (I'm not very good at programming and I've
    been finding the "help" information very confusing.) I've devised
    quite an elegant solution, if only I could get it to work!.
    I'm using a single frame loop with an onEnterFrame
    construction that deletes itself when the flv has finished playing.
    I've set up a movie clip with various start points for animations
    to be activated at cue points. I'm testing for the cue points in
    the same frame, storing previous cue point names so that each cue
    point triggers the corresponding animation once only. I know the
    main logic works because I've tested it with trace statements to
    prove that the cue points are actually being reached. The problem
    is that the goToAndPlay instructions don't seem to activate the
    movie clip as intended.
    My best guess is that the stop action on the self-looping
    frame is also stopping the movie clip as soon as it starts. Even if
    that is true, I don't know how to solve the problem. And I'm sure
    one of you much more clever people will know better. Here's the
    code. Any suggestions?

    You can build out a menu by reading the cuePoints array in
    the NetStream.onMetadata handler, or by using the MetadataEvent
    with the FLVPlayback component (AS3). The simple thing for me to
    say is to refer to Chapter 9 of my new Flash Video book. :) (see
    link in my signature below.)

  • UDLD Normal Question

    Hi all,
    I need some clarification on UDLD please.  I have always used UDLD aggressive mode and understand that with no issues.  What I am not clear on is exactly what UDLD does in normal mode.  According to the Cisco documentation,
    "In normal mode, if the link state of the port was determined to be bi-directional and the UDLD information times out, no action is taken by UDLD. The port state for UDLD is marked as undetermined.  The port behaves according to its STP state."
    If no action is taken in normal mode, is there any value in using it?
    Thanks,
    Bill

    Hi Bill,
    The UDLD is sadly underdocumented in several sources, and even the informational RFC does not contain all the necessary information to properly understand UDLD modes.
    The truth is, according to U.S. Patent 6765877, that there are two ways in UDLD of detecting an unidirectional link: an explicit and an implicit method. To understand the explicit method, it is important to keep in mind that each switch indicates its own [Device ID, Port ID] tuple as the sender information in an UDLD message, and echoes back the [Device ID, Port ID] tuples received from its neighbors in an echo portion of the message. In other words, each UDLD message carries a device and port identity of its sender, and contains an echo list of all neighbors and their ports whose UDLD messages have been received on the port that sends out this UDLD message itself.
    An unidirectional link is detected explicitly if one or more of the following events occur during the neighbor detection and linkup phase:
    UDLD messages received from a neighbor do not contain the tuple that matches the receiving switch and port in their echo portion. This would indicate a split fiber or a truly unidirectional link.
    UDLD messages received from a neighbor contain the same sender as the receiving switch and its port. This would indicate a self-looped port.
    UDLD message received from a neighbor contain a different list of entries in the echo portion (i.e. a different set of neighbors) than the set of neighbors heard by this switch on this port. This would indicate a shared segment with a partial impaired connectivity between connected switches.
    Whenever any of these three events is observed during an UDLD neighborship buildup with a neighboring switch, the link is declared unidirectional and subsequently disabled. Once again, this is called explicit unidirectional link detection. The setting of aggressive or normal mode has no effect on explicit detection.
    An implicit unidirectional link detection refers to the event when UDLD messages arriving from the neighbor device suddenly cease to be received, without the port actually going down. This is where the aggressive or normal UDLD modes make a difference. In the normal mode, you simply age out the neighbor and do nothing, hoping that if there was a physical unidirectional fault on the link, the physical and link-layer mechanism would have brought the link down anyway. In aggressive mode, you assume that the physical layer has no capability of detecting and dealing with the unidirectional link condition itself, and when UDLD messages stop arriving, you err-disable the port just to be safe.
    So the difference between the normal and aggressive modes relates to the difference in handling an implicit uni-directional link event. If an uni-directional link is detected explicitly, the port will always be err-disabled, regardless of the normal/aggressive mode.
    The related U.S. Patent is a good, albeit tiresome, reading on this, especially the Figure 7 with the decision diagram; check out this thread:

  • Do you know a unicast protocol for the Ethernet control plane?

    Hi,
    Does anyone know a protocol for the Ethernet control plane which has a unicast destination address?
    MVRP, MMRP, MSTP, RSTP, all these protocols have a multicast reserved destination address.
    Perhaps we have to look non-802.1Q control plane protocols.
    Best regards,
    Michel

    Hi Peter,
    > I wonder if any of the OAM protocols, especially the one providing the loopback/ping test is unicast-based.
    In G.8013 (07/2011) section 7.3:
    "The Ethernet loopback function (ETH-LB) is used to verify connectivity of a MEP with a MIP or
    peer MEP(s). There are two ETH-LB types:
    • Unicast ETH-LB.
    • Multicast ETH-LB".
    > In any case, think of LOOP frames sent by Catalyst switches to detect  self-looped ports. In these frames,
    > the source and destination MAC  address are set to the unicast MAC of the egress port.
    As I said above, it's a good case for my little study.
    The LOOP frame, from Cisco, was certainly interesting and important before 2004.
    Since 802.3ah-2004 we have the OAM remote loopback (in link OAM, and not network OAM as ETH-LB).

  • Cannot add GRPO - internal error occurred

    Hi,
    Good day!!!
    We encountered this error [Goods Receipt PO u2013 Rows u2013 Warehouse Code][line:0], u2018Internal error (118) occurredu2019 [Message 131-183] when creating GRPO for foreign currency.There are formatted search define on the unit price in the GRPO. When the PO was copied to GRPO the value on the unit price becomes zero but on the PO (based document) there are amount. The error appears only if the transaction is foreign currency but if the transaction is peso they can add the GRPO successfully. Below is the FMS defined in the GRPO.
    SCRIPT:
    declare @UnitPrice Numeric(19,6)
    SELECT @UnitPrice = $[$38.14.number]
    if @UnitPrice > 0
    BEGIN
    SELECT @UnitPrice * 0
    END
    Initially we thought that the error was caused by the FMS search define in the GRPO. As per suggestion of our programmer we edited the script, change SELECT @UnitPrice = 0 to SELECT 0. But still thereu2019s an error when the warehouse code is 01. If the other warehouse was selected with formatted search the GRPO can be added. We tried to remove the formatted search and just delete the amount when it was copied to GRPO before it was posted the transactions added successfully. Then after so many testing, the GRPO added successfully even with Formatted search define in the TEST Database. The original query was attached in the Formatted Search and the GRPO added successfully. But when it was done on the LIVE DATABASE the error still exists. I asked them to refresh the Formatted search and create the GRPO again in the LIVE database but still the error appears.
    Then we have also thought it might be caused by the negative inventory balance of the item in that particular warehouse. But by doing the followig scenarios we found out that this is not the cause of the error. Below is the different scenarios done by the consultant.
    1.     Iu2019ve duplicated the transaction with the same item code and warehouse and the error appeared.
    2.     Iu2019ve test the transaction with the same item code and different warehouse(positive inventory) and we was able to add the transaction.
    3.     Iu2019ve test the transaction with the same item code and warehouse(negative inventory) and we was able to add the transaction.
    Please help us how we can resolve the error encountered above. We did a lot of testing but we cannot resolve the issue.
    Thanks,
    Janice

    Janice,
    $[$38.14.0]
    refers to the Unit Price field which is the same field you are referencing in your query and I think it is a self loop issue which is not getting resolved and hence the error

  • Delta Load to Infocube

    Hi,
    I am facing an issue with delta load to infocube.
    Let me give you the scenaario - I have a standard Infocube and a DSO.
    Data gets loaded to the infocube daily using Delta with filter on sy-datum.
    There a new Key figure which is added as part of the DSO and Infocube recently.
    Our requirement is - we have to populate history for that specific key figure in the DSO and subsequently to the Cube whithout any data duplication for already existing Key figures.
    Hence, we have created a self loop on the DSO updating only the specific key figure.
    Before loading the data into the DSO, while setting the already existing DTP which takes sy-datum is filter to " Initial Update Set".
    Its giving an error which says "Overlapping Selection criteria for DTP".
    Is it something like we cannot change the setting of an already existing DTP?
    If i do a full data will get duplicated for the past dates, hence delta is the only solution.
    But how to go about delta then?

    Jaya,
    If i understand corrctly.....  Data getting loaded from DSO to CUBE through delta with some selection. New keyfigure added to DSO & CUBE ... right...??
    To populate new KF, self loop created(DSO --> DSO) with required mappings(keyfields and new KF).
    Just do full load from DSO --> DSO and push delta to cube. No need to keep any filters while loading from DSO to DSO. Populate new KF for entire data, and while pushing to cube filter is already available at DTP(use exising delta mechanism only from DSO to CUBE). No need of any full load from DSO to CUBE.
    Hope it Helps

  • High and dry....Blu-Ray.

    All,
    I am not here to create a flaming discussion of any type--just to express my current disappointment with DVD studio Pro.
    I am working on several commercial projects and tradeshow programs that need to be presented in HD. I am utterly disappointed with Apple's absolute LACK of support for Blu-Ray at the moment.
    I realize that we are talking about (bleeding-edge) technology, but really folks...Blu-Ray burners and players and media ARE on store shelves. HD-DVD recorders (for the most part) are not.
    POINT: I had to purchase a PC-based program today (Sonic DVD-HD) to do the work of a SW program I already own (DVDStudio Pro).
    Please get it together and support Blu-ray in DVD Studio Pro. Please stop sending me to "the dark side..." for workflow solutions.
    Please.

    Eric. I certainly don't think it will be any "better". They are both sub-$1000 programs. And yes, compared to Scenarist and the few other snooty $100,000 proprietary solutions that only Hollywood owns...well...there is no comparison.
    But that was not my point.
    This is simply an issue about basic features.
    For clarity I was whining (in a very public manner) about having to spend $600 to buy another program to get capabillities that I feel DVDStudio Pro should already have at this point.
    Nothing more.
    I just need to be able to provide HD video content to clients (for their presentations) and not roll it off of a $35k HDCAM or $24k DVCPRO-HD deck.
    I simply feel let down by Apple. Blu-Ray hardware is on the market and they have almost no application support for it. They spent oodles of time and energy building HD-DVD support into their software (Its right there in the DVDSTP menu)...and well...the HD-DVD hardware does not yet exist for retail customers.
    In response to your broad sweeping generalizations of doom and incompatibility:
    This evening (after posting my first frustrated note), I bought the SonicDVDItProHd package (100MB download), authored a simple 10 minute (single video track, 1080i content) self-looping presentation and burned it to a 25gb blu-ray disc that plays in our Samsung set-top blu-ray player.
    It works. No issues. I simpy wish that I had been able to do it from within DVDStudio Pro.
    User Experience: And no, the Sonic package does not hold a candle to DVDStudio Pro. Compared to DVDSTP, the Sonic package is inelegant and lacks most of the advanced features and intuitive working of DVDSTP.
