Can someone explain about frame header size in Ethernet over MPLS

Hello Arun,
Here is some explanation:
http://cciethebeginning.wordpress.com/tag/eompls/
Also I attached pcap file, you can open it in wireshark and look at entire packets. There are some pings 10.0.0.1 <-> 10.0.0.2 between CEs

Can someone explain about Microsoft IAS attributes?

Hi, world!
I'm not able to startup wired 802.1x VLAN assignment throught MS IAS. After authorization port stay in default (access) VLAN.
I've configured attributes according to MS well and looks like I've configured something wrong.
Can someone say, what values should be in fields "Vendor Code", "Vendor-assignment nubmer attribute", "Attribute format" and "Attribute Value"?
Now I have:
RADIUS standard - 64 - string - VLAN
RADIUS standard - 65 - string - 802
RADIUS standard - 81 - string - 10
where 10 is VLAN number.
That does not work.
Thank you!

There's not a way to do this with VSAs. BTW, the ability to do this depends on your switch and code revision. This functionality is effectively achieved by compliance to RFC 2868 and RFC 3580.
So is everything working for you now?
Hope this helps,

Good point, Howard, about the recycle bin. So I cleaned up, recreated the table, filled it, dropped it but did not purge it, and ...

Table created.
SQL> insert into test.x select * from dba_objects;

I cannot find a way to sort the bookmark folders themselves alphabetically by name.I am not talking about in a view mode but in the way they are displayed when I click on my bookmarks tab. Can someone explain to me how to accomplish this.

I have a lot of various book mark folders with websites contained within each folder. I am able to sort the websites within each folder alphabetically by name but I cannot find a way to sort the bookmark folders themselves alphabetically by name.I am not talking about in a view mode but in the way they are displayed when I click on my bookmarks tab. Can someone explain to me how to accomplish this other than manually dragging them as this is extremely hard for me due to the fact that I am a quadriplegic with limited hand movement dexterity

Bookmark folders that you created are in the Bookmarks Menu folder. "Sort" that folder.

Can someone explain the message about replacing songs when importing a CD?

If this is somewhere, I have not been able to find the answer. When importing a CD, sometimes I get a message that asks if I want to replace existing songs. Can someone explain what this message means? I have tried replacing the songs and not replacing the songs, but I don't see any meaningful differences.
Thanks!

You should sort the list on the Album column, ideally as Album by Artist. Generally all you need to do after that is fill in an appropriate Album Artist. For more details see my article on Grouping Tracks Into Albums, in particular the topic One album, too many covers.

Can someone explain to me Vector Class !!

Can someone explain to me, or tell me where I can find a good tutorial about Vector class.....in simple terms....any good simple, easy to understand tutorials???
Thank you.
Rod

Start with this:
http://java.sun.com/j2se/1.4/docs/api/java/util/Vector.html
Essentially, a vector is a single Java object that allows you to store a group of similar things. Each item, or element, inside the Vector must be of the same type, or Java class. The important thing to remember about Vectors is that their size is not fixed. If you don't know how many items you need to store in advance, a Vector is a useful datastore, because you can simply add items into it without worrying about reaching the maximum size. The Vector object will grow itself as you add elements.
The important methods are described in the above API. Read through it carefully.

Multithreading - Can someone explain this ...

Hi Java Gurus:
Can someone explain this to me why my multithreading worked in once case and not in the other.
First a little background:
My application lets the user create multiple JInternalFrames. Each frame has an OK button. When the user presses the OK button, the frame goes about it's business in a new thread, thus returning control to the use, so he/she can press the OK button on the second frame .. and so on.
Following is the event handler for the OK button that creates the new thread:
case1 - doesn't work:
      btnTranslate.addActionListener(
         new ActionListener() {
            public void actionPerformed( ActionEvent e ) {
                         txtOutput.setText("");
                         txtBadParts.setText("");
               Translation trans = new Translation(inst);
               trans.run();
      );case2 - works:
      btnTranslate.addActionListener(
         new ActionListener() {
            public void actionPerformed( ActionEvent e ) {
                         txtOutput.setText("");
                         txtBadParts.setText("");
                   new Translation(inst).start();
      );Thanks,
Kamran

Calling the run method makes the run method run in the current thread. You need to call the start method to get the thread to start its own thread.

Can someone explain how .prel files work?

Can someone explain how .prel files work? My C drive is O/S and programs, my D drive is storage and the project file(s) (the .prel file) are on my E drive.
How is this supposed to be more efficient/faster? P.E. (C drive) has to constantly communicate back and forth across drives with the .prel file and all the files in the subfolders? It seems like it would be slower.
As I mentioned in a previous post; my zooms in/out of the Timeline are VERY slow. It is almost 1 second before the Timeline gets bigger/smaller. Any info would be great,thanks!

By using multiple HDD's, one is spreading the I/O (Input/Output) load over various HDD's. The controller is faster than a single HDD, being tasked to read/write from/to multiple places. One of the first laws of physics is that an object cannot be in more than one place, at the same time. The heads on a HDD are no different. If requests for multiple reads are made, the heads will position themselves over on place on the platters, read, and then move to the next requested location, and so on. However, with multiple HDD's, and a good, fast controller, the heads of each HDD will be placed, where necessary, so reads are done at once, from multiple locations.
For ultimate performance, a good setup would be as follows:
C:\ system OS and programs (more reading being done here, than writing)
D:\ Project files (PREL's in this case)
E:\ RAID 0 Scratch Disks for Media Cache, but not Render files (both reading and writing)
F:\ RAID 0 Media files (more reading, but also writing)
G:\ RAID 0 Export/Share and Render files
Some go so far as to separate out Audio Assets from Video Assets, and use a separate RAID 0 for each
The downside of that "ultimate performance" setup, is that when a Project is completed, to clean up, one has to go to many HDD's, and locations. There can also be issues when Archiving a Project, because things are scattered about.
I get "good performance" by having my Project, Copies of my Assets and all Scratch Disks on one HDD. What I give up in performance, I make up for with housekeeping chores, when the Project is done. I still spread my OS/programs from my Projects, with separate physical HDD's.
Good luck, and hope that this helps,
Hunt
PS - Above, I mention RAID 0, but even greater speed can be achieved via many HDD's in the Array, and perhaps a RAID 50. RAID 0 is just two physical HDD's. Also, for RAID, I recommend a dedicated RAID controller card, and NOT software, or the MoBo's RAID capability.

Trying to understand RSTP - Please can someone explain this?

Hi Group
I am still confused about how RSTP is implemented. From what i understand the major difference is that STP
used Timers for Loop prevention whereas RSTP coordinates between neighbors via messages (proposal/aggreement) to turn on links
more quickly after topology changes and is "timer free".
However, I have not noticed any difference in the configuration from the legacy STP
configurations and the RSTP configuration on cisco devices. Or are there any differences??
I have read in documentation that RSTP natively includes features like UplinkFast, BackboneFast and PortFast. So are these features now obsolete
and not needed to be configured if you are running RSTP. (Although i have seen Portfast still configured along with RSTP on many switches)
Also can someone explain the below Points from Cisco Documentation
1) should STP be disabled on edge ports all together as suggested below?
"STP edge ports are bridge ports that do not need STP enabled, where loop protection is not needed out
of that port or an STP neighbor does not exist out of that port. For RSTP, it is important to disable STP
on edge ports, which are typically front-side Ethernet ports, using the command bridge
bridge-group-number spanning-disabled on the appropriate interface. If RSTP is not disabled on edge
ports, convergence times will be excessive for packets traversing those ports."
2) It seems RSTP relies on duplex setting to determine inter-switch links. What is the configuration to explicitly
configure RSTP link types? (I couldnt find this in the documentation)
"RSTP can only achieve rapid transition to the forwarding state on edge ports and on point-to-point links.
The link type is automatically derived from the duplex mode of a port. A port that operates in fullduplex
is assumed to be point-to-point, while a half-duplex port is considered as a shared port by
default. This automatic link type setting can be overridden by explicit configuration. In switched
networks today, most links operate in full-duplex mode and are treated as point-to-point links by RSTP.
This makes them candidates for rapid transition to the forwarding state."
Also i am a bit rough on my RSTP knowledge even after skimming a few Cisco documents. Can someone please explain this in simple way.
Thanks in advance

to configure it on a device:-
spanning-tree mode rapid-pvst
PortFast/UplinkFast & BackboneFast were cisco "Enhancements" to 802.1d STP. RSTP just incorperates them. If you want to configure portfast, the command is still "spanning-tree portfast"
OK
1) That is your choice - I have bitter experiance of users/IT admins just plugging hubs/switches in when ever they can. Also cabling the switch back to itself creating a cabled loop. So my advice to you is to leave STP enabled on all switch ports, BUT enable BPDUGuard - this is a life saver, if you have configured portfast.
2) duplex auto! or duplex full (overiding)
I really suggest that you read the 802.1d standard, once you understand normal spanning-tree - RSTP will come to you.

CAN SOMEONE EXPLAIN ME THE DISPLAY QUALITY

I have just purchased a new macbook pro 15" 2.4ghz. Im a designer, i havent even created my appleid, im on my sisters... i made a sacrifice to buy this $2700 laptop.
and Im so dissapointed...
I CANT SEE SMOOTH GRADIENTS.. all i see are ugly lines... i dont get it, for such a high class LAPTOP.
Apple support please help me solve this. ive been reading forums about 6bit screens for this laptop.. i dont want to believe that. can someone explain? im returning this...

I can verify that all of Apple's laptops use 18 bit (6 bits per Red, Green Blue) color, which is about 260,000 colors. The OS then using dithering to fake the missing colors. Despite what you have read, they are incapable of 24 bit 'millions of colors'.
The problem with this argument is that, when it comes down to it, the color displays are made up of dithered red, green, and blue elements anyway. We accept that this form of display gives us "full color", so it's difficult to argue that millions of colors can't be represented using the same mechanism. It's not quite 16.7 million (more like 16.3 or something) but Apple's text has always taken care to read "millions of colors" rather than 16.7 million (which you'll still see on the specifications for the Cinema displays).
Just for informational sakes though, these kinds of 6-bit displays don't rely on OS spatial dithering; they actually make use of their very fast switching to perform temporal dithering, switching a pixel between two shades very quickly to generate an in-between shade. That's why for most people the result is usually visually indistinguishable from true 8-bit color, and doesn't look like what you'd see with traditional dithering.
If the OP is noticing severe banding on gradients, it's more likely to be an issue with color profiles than with the display being 6-bit.

Can someone explain the tables tab under function parameter declaration ?

Hello,
when declaring a function, part of its parameter interface is the tables tab. So if in FUNCTION1 i declare a table: tdraw like draw (optional)
what does that mean ? does this mean that tdraw will be a table of type draw and at the same time it will be filled up with the same contents as draw has ?
then how can other function (func2) use FUNCTION1 and its table ?
so if inside func2 i also have an internal table AA like draw :
so inside func2 i say:
call function1
tables:tdraw = AA
does this mean that it will assign the result tdraw table of function1 to AA ?
can someone explain details of internal tables and passing them as parameters ?
and which table is assigned to which ?
thank you

Hi hassan,
If you are talking about the tables parameter in SE37, when you declare a table tdraw like draw it only means you are declaring an internal table of type draw but the contents are not filled into it.
In the source code of the program you have to write the code to fetch the data to tdraw and do the manipulations accordingly.
Also, the tables you are declaring can be like the input table or can be used for output table.
suppose u have 2 tables tab1 and tab2, tab1 you are going to input the values to it and the calculated values have to be in another table, you can use tab2 as the result table.
hope it helps.
award points if it helps.

Can someone explain this flashmo sample?

Hi,
I'm a newbie in flash and looking at this sample project.
http://www.flashmo.com/preview/flashmo_169_intro
I opened it with flash cs3, and can see actionscript on the actions layer, and can see symbols in the library. However, I cannot figure out what makes the symbols swoosh in/out in sequence. The actionscript on the actions layer does not have that, or so I figured.
Can someone explain where I need to look at?
Thanks.
Ben

This is another good reason for never using scenes in Flash designs--they put things where they cannot be easily found. There is no actionscript for the animations, but there is a second scene that contains all of the animation. If you open the secnes panel you will find a second scene that includes all of what you are wondering about.
Ooops, sorry Rob. ....bad timing.

Can someone explain pricing?

I'm a bit conflicted about pricing issues with other english-speaking countries. Can someone explain the process?

Just like with apps, there is a floating/similar price based on the same tier, region by region. That's why Apple uses tiers, so they can adjust localized pricing while keeping the same tier. If you want similar pricing across regions, use the same tier in all.
This goes back to when music was the only thing in the store and it's not unusual for Apple to make adjustments from time to time. I believe it's a concession to the various industries, etc.

Can someone explain me well when the infopackage use batch or dialog?

Hi Gurus,
can someone explain me well when the infopackage use batch or dialog?

Hi ,
first of of in Bi_btch job nothin comes in the log .. but if you use PSa and then into data target then it willl definatly create background jobs .. but i feel it doesnt relate to the concept you are taking about ..
if you us e a sepeate update from PSA step the it will create backgroung jobs ..of king bi_btch and if you push the packets maually then it will create jobs like bi_book .. thats the diff ..
The initialization and execution of an InfoPackage is implemented as a process type in the process chain maintenance. The Start Later in Batch setting is hidden if the InfoPackage is used in a process chain. This is because the start of the request is determined by the process chain itself.
If you do not use the InfoPackage in the process chain maintenance and you want to process the data request in the background, select the radio button Start Later in Batch and define the required start time. If start times already exist for this data request, this is indicated with a next to the Scheduling Options pushbutton. You can change the start time using Settings Options. You can also enter an end date for the data request with a background job.
If you schedule an InfoPackage in the batch later, the background request job runs until all data is updated in BW. This is displayed with a corresponding indicator in the Schedule tab page. The load process remains active until the data is updated.
For example, this gives external scheduling tools the option of monitoring the request job. The job then also runs with a request from an SAP source system as long as the source system has sent the data to the BW system and posted it or until the monitor sets the request to red. In the job log, a success or error message is displayed according to whether the request was posted successfully or not.
