Tunnel Transport MTU different from Configured MTU

Hi,
I have the following -
interface Tunnel0
 description VPN TEST
 ip address 172.27.240.10 255.255.255.252
 ip mtu 1452
 ip virtual-reassembly in
 qos pre-classify
 tunnel source FastEthernet0/1
 tunnel mode ipsec ipv4
 tunnel destination x.x.x.x
 tunnel protection ipsec profile TEST
end
However, when I do a show interface tu0 I see the following - I have omitted most of Output from this. Is there a specific reason for the difference in 6 bytes?
Tunnel0 is up, line protocol is up
  Hardware is Tunnel
  Description: TEST
  Internet address is 172.27.240.10/30
  MTU 17886 bytes, BW 100 Kbit/sec, DLY 50000 usec,
     reliability 255/255, txload 255/255, rxload 255/255
  Encapsulation TUNNEL, loopback not set
  Keepalive not set
  Tunnel source xxxx FastEthernet0/1), destination yyyyyy
   Tunnel Subblocks:
      src-track:
         Tunnel0 source tracking subblock associated with FastEthernet0/1
          Set of tunnels with source FastEthernet0/1, 1 member (includes iterators), on interface <OK>
  Tunnel protocol/transport IPSEC/IP
  Tunnel TTL 255
  Tunnel transport MTU 1446 bytes
On the opposite end of this VPN tunnel - I see the following -
interface Tunnel32
 description TEST VPN
 ip address 172.27.240.9 255.255.255.252
 ip mtu 1452
 qos pre-classify
 tunnel source FastEthernet0/0
 tunnel destination y.y.y.y
 tunnel mode ipsec ipv4
 tunnel protection ipsec profile TEST
end
When I do a show interface Tu32 however, I do not see the transport MTU configured as i do on the other router so I'm not entirely sure if the route is indeed honoring my IP MTU command of 1452
sh int tu32
Tunnel32 is up, line protocol is up
  Hardware is Tunnel
  Description: TEST
  Internet address is 172.27.240.9/30
  MTU 1514 bytes, BW 9 Kbit, DLY 500000 usec,
     reliability 255/255, txload 48/255, rxload 148/255
  Encapsulation TUNNEL, loopback not set
  Keepalive not set
  Tunnel source y.y.y.y (FastEthernet0/0), destination xxxxx
  Tunnel protocol/transport IPSEC/IP
  Tunnel TTL 255
  Fast tunneling enabled
  Tunnel transmit bandwidth 8000 (kbps)
  Tunnel receive bandwidth 8000 (kbps)
Any ideas on why I am not seeing my configured MTU under the show interface command?

Hi. Did you ever find out the reason and a solution to this problem. I am having the same issue where CUSP decides to change the transport type to TCP (from UDP) when talking to CUCM on certain invites from Acme SBC. On some invites from the same Acme SBC, CUSP doesn't change the transport type and leaves it as UDP.
Thank you.

  • Applications fail when "mpls mtu 1526" is configured

    Hi,
    I'm facing an issue with an MPLS VPN backbone.
    A customer's IP host at one location can ping and traceroute to application servers at it's central site at another location. The IP path traverses four P/PE routers, as follows:
    IP Host (spoke site) -- CE1 -- P/PE1 -- P/PE2 -- P/PE3 -- P/PE4 -- CE2 -- Servers (central site)
    However, access to all applications fails.
    Network configurations as follows:
    (1) All the P/PE routers are Cisco 7609, SUP720-3BXL, IOS 12.2(18)SXF6.
    (2) All the core links are configured with "mpls mtu 1526".
    (3) All the core links are GE, connected to SPA-2X1GE on a 7600-SIP-400 linecard. Some connect to the SFP port on the SUP720.
    (4) Only some of the P/PE routers are configured with "ip tcp path-mtu-discovery".
    After removing the command "mpls mtu 1526" from all core links, access to all applications and services works again.
    Please advise if I've configured anything wrongly.
    Thank you.
    B.Rgds,
    Lim TS

    There are two ways to look at this,
    1) First To solve the problem, on all your Core and Core Facings links configure "mtu 1526 or larger" (PE-P, P-P) mtu 1526 or larger.
    2) Second "MPLS MTU 1526" command only helps in labelling the fragmented payload which is beyond 1526. Till then if anything is fragmented it doesnt label the fragments.
    So now why does it work when its removed,
    a) verify what is your actual link mtu.
    b) "mpls mtu" command doesnt change the physical mtu it just tells the IOS when to label fragments. and the 1526 is the threshold to fragment the labelled packet and label the fragments also.
    c) One important thing to note is even when you dont configure the "mpls mtu" command it is still there by default but now it uses the MTU value of the physical link, so if your link is of 1500 MTU the default "mpls mtu" is also 1500.!
    d) also go through this previous thread for more information the same topic has been discussed at length.

  • HT1277 I want to set up my email composition with a default me@alumni.myschool.edu address that is different from my ISP.  How do I configure?  Command line OK with me.

    Hi everyone,
    I want to set up my email composition with a default [email protected] address in the "Reply-to" field that is different from my ISP.  How do I configure mail to set this default? 
    I have looked through the help and fail to see an option in the Preferences -> Compose window. 
    I am OK with UNIX Command line tasks if that is the only way to set this default.
    Basically I have an alumni email redirection service, which is an address that never changes, even if I change ISP.  That way all my friends can use it an never change.  However, they tend to use whatever ISP address is, not what I have asked them to use. 
    I want to force emails I send to default to my alumni address when my friends reply, not my ISP address.  I want control over this.

    Confused Once Again wrote:

    Email preferences --> select Account --> Account Information tab --> Email address.
    The Email address setting supplies the "from" mail address in a sent email for that account.
    I  been doing this for years (well in Eudora but it works in Mail too) since my return address is a mail forwarding service.  That lets me switch ISP's and no one is ever the wiser.  I just change the forwarding service "pointer" to point to my new ISP.  But everyone else see sees the same "from" address as it's always been.

  • Transport of Customizations from ECC 5.0 to ECC 6.0

    Hi,
    We have some customizations done in ECC 5.0, which we now want to implement in ECC 6.0 (Freshly Installed). Can we transport these customizations directly to ECC 6.0 (after checking the release notes to see if any functionality has changed between the versions, which would effect the customizations).
    If not, is there some other method which you would suggest.

    Hi,
    SAP typically does not support transports between different releases for consistency reasons. SAP will usually explicitly document where it is possible (usually in a SAP note).  I personally have not seen one for mySAP ERP 2004 and 2005.
    If you do transport between releases SAP can't validate that the transport was successful (i.e. all table entries and data dictionary entries are consistent logically and from a business configuration perspective).
    I think you have three options:
    1. copy your mySAP ERP 2004 system to the "new install" server and upgrade it to mySAP ERP 2005.
    2. Install a new mySAP 2004 system, do initial configuration, import your transports, and then upgrade it.
    3. Install a new mySAP ERP 2005 and manually recreate the configurations.
    All have pros and cons. I would usually recommend #3 as your configurators will have documented their configurations in detail so it should not be too difficult to re-implement them (right?)
    I hope this helps,
    Mike.

  • Why does Photoshop display colors differently from the other applications even in sRGB mode ?

    Hello all !
    Here is my problem :
    Photoshop is set to use sRGB workspace (in edit/colors.../workspace/RVB).
    If I understand correctly this is how all native windows applications work.
    This means Photoshop and the other applications should display the same colors on a file with a sRGB profile.
    Now this is the case until I calibrate my monitor.
    When I do, Photoshop colors become different from the other applications (irfanview, explorer, browsers...).
    The only way I found to let everything display the same colors is to set Photoshop to use Proofing/RVB Monitor.
    What upsets me even more is that Photoshop colors look "better" to me (dark grays seem to dark to me in the other applications.)
    I have read that this is because Photoshop takes the new profile into account and others applications do not. But I don't think this is relevant here because everything is in sRGB so the only profile is my monitor's and I think calibration is handled globally by windows : everything (including browsers, explorer, and Photoshop) changes color if I choose to apply the monitor's profile or not with windows color management tool ("use my parameters for this device").
    Here is my system configuration :
    - Photoshop CS4 (11.0.2)
    - Windows 7 64 bits
    - HP ZR2440W and DELL 2209WA (these are not wide gamut screens)
    I have spent two days trying to figure the logics behind this and really am upset. Any help would be greatly appreciated. Don't hesitate to ask me if there is something that is unclear or some information I forgot to mention.
    Thanks in advance,
    Yannick

    That sounds like an invitation to continue to talk about the issue.  Fair enough.
    I'm not sure where you're getting "insecurity"...  I am just trying to help you help others more effectively.
    I invite you to re-read just the first sentence of what you wrote very carefully, putting yourself in the shoes of someone struggling with both the terminology and the concepts:
    Photoshop (CMS) reads an embedded ICC profile and CONVERTS it to the custom monitor profile for a theoretical 'true color' display
    Think about what "Photoshop (CMS)" might mean to a person who doesn't know the acronym might stand for "Color Management System" (which is I assume what you meant).  Adobe themselves don't call it "CMS", they use the acronym "CMM" (Color Management Module).  The term "CMS" is used in the computer industry for about a dozen different things.
    While a color profile might have been embedded in an image file before it was opened by Photoshop, Photoshop works on documents.  A profile is not "embedded" in a document, it is maintained by Photoshop with the document and describes the color values in the document.  If Photoshop opens a document without an embedded profile, depending on settings and user choices it might assign a profile or it might even operate on the document without color-management.  Oversimplification doesn't help people when they're trying to learn new things unless it's described as such, for example, "This is a bit of an oversimplification..." or "Generally speaking..."
    Not every monitor profile is a "custom monitor profile".  Quite often a standard profile (e.g., sRGB IEC61966-2.1) is associated with a monitor by the operating system as a default, or a factory profile is installed by a driver package or system update.  Your use of the term "custom" is a bit ambiguous and could be read as implying the creation of a profile using a calibration and profiling device specific to the particular monitor.
    Photoshop's color management code does not convert an embedded ICC profile at all (read carefully what you wrote).  As I said, it transforms color values.  That was the key error in your description that prompted me to comment.
    If ever there is a time to pick words carefully, it's in a color-management discussion.

  • The waveform of output from file is different from original one

    I've a new question about displaying a waveform from a text file. The waveform which its data is from file is different from the original one.
    I attached image files which included my two vi files and 3 waveform. In the compressed file, "ReadData_Waveform1.jpg" is a image of waveform from "ReadData.jpg" vi file with the configuration of "Transpose" is True,
    "ReadData_Waveform2.jpg" is a image of waveform from "ReadData.jpg" vi file with the configuration of "Transpose" is False,
    "WriteData_Waveform.jpg" is a image of waveform from "WriteData.jpg" vi file.
    I attached the source file of waveform with text format as well.
    Please help me to solve this question if there is anyone who can figure it out.

    Hi Andy
    If you transpose the data when you write it, you also have to transpose it when you read it.
    Just have a look at the simple example attached. I write data and read it again. Each file operation is called with the default-value for transpose (false). The data is read correctly.
    Hope this helps.

  • Transport to different location

    Hi All,
    I been go through standard KM Content transport method and ICE protocol transport. My requirement is to transport KM content (basically folders and docs) from Dev to Prod server but in a different location. For example, in Dev, the content i want to transport is from:
    /my_stuff/
    But after i saved the achieve file, i want to transport to a different location in Prod, e.g.
    /my_stuff_at_dev/
    But both standard KM transport method and ICE will replace/create achieve files from one server to the same location of the other server. So is that possible to transport to different location in the target server?
    Thanks in advance!

    Hi Raghu,
    Thanks for your answer.
    Is that mean i need to, say in Prod server:
    1), create a temporary repository in KM
    2), cut/paste the original my_stuff folder and its content to the temp repository
    3), transport folder my_stuff from Dev to Prod
    4), rename it to my_stuff_at_dev
    5), cut and paste my_stuff_at_dev to the temp repository
    6), move Prod's original my_stuff folder from the new repository back to its original position
    Am i right for these steps?
    Thanks!

  • Importing transports in different versions.

    Dears,
    I want to confirm that is it possible to perform transports in different version systems.Our requirement is to create the request from ECC5 and then import it in our Netweaver 04s server.
    So first I want to know is it possible and second thing as i know for it i have to only manually copy cofile and datafile in target system and then by STMS add to buffer and then import,Is there anything else also i have to do like changing file permission.I am using windows 2003 server.
    Please suggest.
    Deepak

    as u would be aware transport is done by r3 trans
    different versions of R3trans are fully compatible with each other, because the data is transported in a standard format. Thus one can use different versions of R3trans for export and import.
    Transports between different databases or operating systems are not a problem either.
    When you transport between different SAP release levels, note that this usually does not present any technical problems due to the upward and downward compatibility of R3trans , but logical inconsistencies could occur in such transports
    Further technical and logical problems for the various releases are outlined in notes 60928, 120151, 126776 and 330267.

  • Transport a request from one server(quality) to another server(production)

    Hi All,
    I want to transport a request from one server(quality) to another server(production)
    Can we transport a request from quality to production programatically i.e. by using programing logic.
    Regards,
    Swarup

    Hi,
    It cannot be done programmatically. Although it can be automated by basis guys. They configure it in TMS (Transport Management System). You can check it using STMS. (if you are authorized to view it).
    Transport path are defined in TMS.
    For Automated Transport configuration is done in TMS.
    Generally automatic Transport are not setup between quality and production. Changes are first tested in Quality and then Transported by basis team either periodically / individually.
    In case of manual transport Transport Request can be imported in production using STMS_IMPORT transaction in production. (Basis guy will do it for approved Transports)
    If there is no direct connectivity - Basis people copy "data" file and "co" file and Transport it to target server (This is generally not the case in Quality - production as Transport path is always defined).

  • Is it possible to move some tools or their setting parameter from Configuration interface to Inspection Interface?

    Hi
    We use Vision Builder for machine vision. There are two interfaces in Vision Builder (Inspection Interface & Configuration interface). It is better machine vision operator would work with Inspection Interface and he should not access to all of setting and tools but he need to redefine some parameter like RIO in some tools like measuring tools for different products.
    Is it possible to move some tools or their setting parameter from Configuration interface to Inspection Interface?
    Or is it possible to define security like password to some tools and their setting but not all of them?
    Thanks
    Refa

    Vision Builder generally isn't supposed to rely on user input, but there is a step called "User Input" that allows you to get input from the user. ROI would be tricky. I think the slickest way to do that would be to create a VI that displays the image, lets the user drag a rectangle, then pass those coordinates back to Vision Builder to configure the ROI.

  • IO 229 - Batch for serial number 1234 (BBB) differs from document batch AAA

    Hello All,
    We use batch management for serialized materials only at our central plant. For all other plants, there is no batch control. Sometimes we need to return materials back to the central plant but with a different batch number.
    When we do two step stock transfer 303 / 305, we receive the following error message if we don't use the original batch number.
    "IO 229 - Batch for serial number 1234 (BBB) differs from document batch AAA".
    However, when we use one step plant to plant stock transfer 301, there is no error message. The batch number is also updated correctly in IQ02.
    I wonder if there is any configuration to use 303 / 305 with different batch numbers.
    Thanks,
    Hakan

    Thanks Arminda.
    64044 recommends to use 309 to change the batch, which works but this is an additional step.
    Currently 1 step plant to plant transfer i.e. 301 doesn't require this additional step. It updates the batch information with no problem.
    Is there any configuration option to change the behavior of 305, so that we don't have to do an additional movement?

  • Ordering unit different from invoicing unit

    Hi all,
    My client procures steel. In PO, they want to buy with ordering unit EA, but when invoicing, they want it in KG (because based on the law here, invoice for steel must be in KG).
    We suggested them to use ordering unit KG because in SAP, PO unit and invoicing unit have to be the same.
    Is there anyway/configuration to allow the PO unit different from invoicing unit?
    Thanks,
    Trang

    Hi,
    You can have order unit as EA and Order price unit as KG while creating PO.
    For ex:
    Order qty: 10 EA
    OPU: KG
    Under item tab quantity/weights in PO, you can give the conversion factor as 1 EA = 2 KG or maintain the conversion factor in additional data of material master.
    Price will be calculated for 20 KG during invoice.

  • How to transport modified query from Dev to QA??

    Hi All,
    I have made a few changes to a query that has already been transported to QA from Dev. I have removed an Infoobject and introduced a new Infoobject and other such changes.
    Now I would like to transport the "new version" of the same query from Dev to QA again so that all the new changes are reflected in QA environment as well.
    What steps or procedures do I need to follow for this please?
    Thanks for your time,
    Regards,
    Reddy

    Reddy,
    BW reporting objects (query / Workbook / WAS tempalte) change transport system is different than other BW development objects (Infoobjects, cubes, transfer/update rules etc..).
    Before you start making changes to any Query objects (which are already transported before), first you need to assign the respective Request in the "Transport Connection" tab (click on the BEX with truck symbol icon) and assign your request with the package name.
    hope this helps a little..
    Good luck

  • Ship to party different from payer

    Dear friends,
    I have one payer and three ship to party pls how would the settings be done in a scenario like this. where my ship to party is different from my payer or bill to party.
    Also, what is the different btw sold to party, ship to party, bill to party and payer
    Thanks in advance

    Hi Eki,
    Its a very basic question.
    Go to Google.com and simply type "what is XXXX to party in sap".
    It will give you the best result and regarding the scenerio, once you understand the partner functions then it will be easy to configure such scenerios.
