Difference between 802.1x multi-host and 802.1x multi-auth

Hi,
This is a bit confusing for me. Does someone has an easy explanation?
What I understand and looked up for the moment (correct me if I'm wrong):
802.1x multi-host: Good for an AP or a phone setup. Port becomes authorized as soon as one client is authenticated. In this situation the AP or the phone. Aftherwards pc's have access without any further 802.1x action.
802.1x multi-auth: Multiple devices are allowed to independently authenticate through the same port. More secure? Is this good for next setup: I have a 802.1x port on the managed 24p switch, but the customer decides to plug in a non-managed 8p cheap switch on his desk where different pc's will be plugged in. So I have a 802.1x port on the Cisco switch connected to a non-managed 8p switch. I suppose 802.1x multi-host configuration is not a secure option here.
I don't know if I am clear enough. Don't hesitate to ask if not.
Thanks for your reply.

You are right with your understanding.
Multi-Host is a valid solution if a power-user for example is using many VMs on his PC. After authenticating initially, all VMs can communicate with the network.
Multi-Auth is more secure because each MAC address accessing the network is controlled.
A very good overview on 802.1x and the configuration can be found on the Cisco IOS Quick Reference Guide for IBNS.

Difference between cleared items,open items and all postings (FI).

Hi experts,
Can anybody tell me the difference between cleared items,open items and all postings for an account.
While running corresponding bapis and transaction FAGLL03 (for GL) or FBL1N (for accounts payable) i found that in some cases all postings is less than cleared items or open items for a time period. How could it happen.According to my knowledge all postings should contain cleared items and open items.
Please correct me..
Thanks and Regards
Arjun

Hi Arjun,
For every Billing Documnet created(VBRK/VBRP-VBELN) there will be an accounting document created in BSID/BSAD tables.
OPEN ITEMS means the Billed/Invoice Amounts that are pending from Customers, i.e which we have to receive from Customers.
CLOSED ITEMS means the AMOUNTS received from that customer.
OPEN ITEMS : fetch data from BSID table Only
CLOSED ITEMS : fetch data from BSAD only.
ALL POSTINGS : fetch data from both BSID and BSAD.
Hope this will help.

Nitin.

The Difference between iphone Unlock T-Mobile and iphone Unlock Free-Sim

As mentiond in the title my questions are:-
- What is the Difference between iphone Unlock T-Mobile and iphone Unlock Free-Sim?!
- Did they both work Internationally?!
- For the Unlock T-Mobile should i use their sim or i can use any sim directly?!
Thanks

Unlocked means unlocked and you can use any sim card and keep changing them and the phone will never lock if it is unlocked.
Sim free, means that the phone is sold at full price without a sim card, but the phone will lock to the first sim card that you put in it. A sim free phone will work internationally, but you will have to use a roaming plan with your phone company because the phone will be locked, so you CANNOT change it to a local sim card.
If you have an unlocked phone, you can use it internationally by inserting a local sim card and the phone should then work and you won't have to pay increased roaming charges as you would with a locked phone.
If you buy a T-Mobile phone that is unlocked, DO NOT activate it with their sim card or the phone will lock to T-Mobile and you will have to approach them to get it unlocked. Use it with another sim card straight away and it will remain unlocked.

The Difference between Extending a Wireless network and WDS?

I have an Extreme (n) and an Express (n).
I want to make sure the signal is strong upstairs and share a printer (connected to the express) and use AirTunes. I also may add an external drive to the Extreme.
What's the difference between Extending a Wireless Network and using WDS? Will there be a speed difference?
Message was edited by: J. Christopher Edwards

I think you don't get it
If I have another draft N router that operates at 2.4G and I have only n devices I can still use WDS and it will connect using draft n in the 2.4G band.
If one g device connects to the network will go in mixed mode.
The AEBS will still report 130 Mbps for your n clients and 54 for your g clients.
If the other router is g only obviously you can't connect between the two router at n mode but still the AEBS will be in mixed mode and not in g. The Extreme will still report 130 Mbps for the connected n clients.
I can tell you that because I have actually implemented it am not taking off the documentation.
The same device if I try to use the "extend n network" does not even see the AEBS but will happily keep the n in the WDS mode and though the bandwidth is halved it is still more than g.
In any case enough for this!

Getting Big Headache, What is difference between Flash Lite 3.1 and Flash Player 7

Hello, I am asking questions about the two similar yet different programs for Pocket PC version only:
1) Which came first, Flash Lite 3.1 or Flash Player 7?
2) If I have both in my Pocket PC, will there be product incompatibility?
3) What is the difference between Flash Lite 3.1 and Flash Player 7.
4) I have a Flash Lite 3.1 but uninstall information says "Flash Lite 3.1 for Opera Mobile", did you releaase this? Is this an illegal copy? A developer's copy?
*I don't know exactly where I got it, but I got it from the HTC developer's forum: XDA-developers.com
*I also use Opera mobile, a web browser for Pocket PC's.
5) What is difference between Flash Lite 3.1 and Flash Lite 3.1 for Opera? Is the only difference is that Flash Lite Supports everything flash related, while Flash Lite Opera supports only flash in opera?
Hi, I don't expect all answers, but I hope someone or someone from adobe support can clear some things up for me.

The program under my "remove programs" list is specifically called "Adobe Flash Lite for Opera". The XDA forums people said along time ago that it was Flash Lite, and kept calling it Flash Lite, and not Flash Player 7.
Now what about this:
http://www.adobe.com/products/flashlite/version/
The table shows the differences between FP 7 SDK, FL 2.1, and FL 3.1. And it's quite obvious that FL 3.1 has way more features than Flash Player 7. What does SDK mean? And why are you telling me FP 7 has more features?
With this information, can you or anyone else provide any more details and clarification?

What's the difference between a not-initialed object and a null object

hi guys, i wanna know the difference between a not-initialed object and a null object.
for eg.
Car c1;
Car c2 = null;after the 2 lines , 2 Car obj-referance have been created, but no Car obj.
1.so c2 is not refering to any object, so where do we put the null?in the heap?
2.as no c2 is not refering to any object, what's the difference between c2 and c1?
3.and where we store the difference-information?in the heap?

For local variables you can't have "Car c1;" the compiler will complain.That's not true. It will only complain if you try to use it without initializing it.
You can have (never used, so compiler doesn't care):
public void doSomething()
   Car c1;
   System.out.println("Hello");
}or you can have (definitely initialized, so doesn't have to be initialized where declared):
public void doSomething(boolean goldClubMember)
   Car c1;
   if (goldClubMember)
       c1 = new Car("Lexus");
   else
       c1 = new Car("Kia");
   System.out.println("You can rent a " + c1.getMake());
}

What is the difference between component(Y, Pb, Pr) and component(R,G,B)?

[I previously posted this question in another thread as hadn't realised how to post new question]
Q. What is the difference between component (Y, Pb, Pr) and component (R,G,B) ?
I’d previously thought I was reasonably savvy on all things HD, but when I turned my thoughts to looking into getting a mac mini to run part of my home cinema I realise I have some confusions around the above.
Here’s what I think I know:-
The mac mini has a DVI output of the type which can output both digital and analogue, and so via physical adapters it could be used to connect to displays that take HDMI or VGA style RGB leads.
I know on the market I can get a DVI to Component cable lead which would therefore lead me to assume it could drive my HD plasma with component input (Y,Pb,Pr), as I currently drive the HD TV via component cable with a SKY HD box (720p and 1080i), an xbox 360 (720p) and a progressive scan DVD player (480p), all through a Denon AV-amp.
The problem is, I’ve heard somewhere that the DVI to component is R,G,B only and that it is not Y, Pb, Pr which is making me wonder it a) this will work and b) if I really understand component video afterall.
I notice the Apple TV outputs Y,Pb,Pr but colours them red, green and blue, so am even more confused….
Hopefully someone can help educate me on this !

Thanks for this.
My Plasma is a Panasonic 42" Viera March 2005 model. No HDMI, No VGA.
It can process signals up to 720p and 1080i via the component (an interestingly it makes a huge difference over SD even though the native panel is 480..!?!)
Am I right in thinking that the iPod component cable will also be R,G,B and therefor might be a suitable trial? Ie. if the TV accepts the input from the iPod then it should work for the mini?
Only other thing of note is I'm doing all this via my Denon 1707 AV amp which does have the facility of upscaling, but I imagine it needs to stick to one format?
Thanks.

Difference between F.35 Receivables amount and FBL5N report open items

Hi All,
There is an amount difference between f.35 receivables amount and fbl5n open items amount, I have observed that there are some changes to credit master like risk category and credit representative group, so I thought if we run f.28 it will be right but still difference exits.
If anybody has come across similar issue or if you have any idea on this on how to analyze, please let me know.
Regards,
RK.

Hi ,
Please check the time horizon in credit check used. then compare it with FBL5n.
May be there will be difference in comparison period.
Program RFDKLI20 or F.28 is to run when there is changes in Assignment from company code, entry in customer master data, entry in sales area data, user exit., currency of credit control area , Assignment of customers to credit accounts.
And
Program RVKRED09.--> only the risk class was changed it is sufficient to run

Difference between sales order schedule line and item level data

Hi All,
Could you please let me know what is the difference between sales order schedule line and item level data?
Thanks,
Ramya

Hi Ramya,
Sales order schedule line contains del date, order qty, rounded qty, confirmed qty, delivery qty, schedule line category, purchase requisition etc., ie It contains the full details of sales order data with respect to the scheduled line of delivery. The total quantity of a sales order item can be subdivided into schedule lines that contain the various subsets with the corresponding delivering dates.
Sales order Item level data contains details of the item in the sales order like material code, net price, net value, UoM, PO details, reason for rejection if any, material group,billing date, plant etc., ie this
contains the full details of item irrespective of scheduled line.
