Monitoring Multilink PPP with Analyzer

I am trying to monitor MPPP link with fragmentation and interleaving
using Agilent WAN Advisor(latest v.15.0), but it seems this box can not decode fragmented PPP, so I have no visibility and right statistics of the link
and layers 3&4. Does anybody has any idea how to get this working, Agilent
Support has been not too much helpful till now.
Alternatively, does anybody knows any WAN Analyzer able to do this.
It would be also great if it would be able to decode cRTP.

I believe that sniffervoice will do this:

Two T1 lines and multilink PPP question

We are getting an additional full T1 line from our ISP for failover and increased bandwith. Each T1 line will go to different NOCs. We decided on multilink ppp (MLPPP). Our ISP told us that traffic will be transmitted on both T1 lines. Packets from one NOC will go to the other NOC, reassembled and send to WAN. In the event one NOC fails, all traffic will go through the other one.
I understand two MLPPP lines must terminate on a single router at a single location. Is what I mentioned above possible?
I also have a 2651XM router with 256MB of memory. I need two seperate WIC CSU/DSU integrated T1 modules. Can someone recommend a model?
Thanks

The most common implementation is indeed MLPPP which terminates multiple PPP links on the same end devices. There is also an implementation of multi-chassis multilink which can terminate ppp links on separate chassis. I guess that is is possible that the chassis could be in separate NOCs. I have no experience with this implementation where the participating routers are in different NOCs, but I assume that it could work.

Multilink PPP problem

Hi Guys,
i got a situation here and hope someone will be able to help me out. Recently i configured a PPP multilink and am facing some issues after that.
Issue 1:
There seems to be lot of input error on multilink interface (150 errors in 40 mins)
Issue 2:
when any of the multilink member interface goes down (all other links are active), am getting packrt drops and request timed out when i ping my other end multi link interface atleast for some 30 sec , after which my response is ok.

MultiLink PPP Processor Load

Is there a large increase in Processor Load when using MultiLink PPP to bond T1s together while running MPLS? We have been requested to bond circuits for customers, but are reluctant because of the danger of over utilizing the processor on our 7206s which are mostly NPE-400s and some NPE-G1s. Is there a reference somewhere to the increase in Processor Load caused by MPPP?

Hi,
Cisco does not publish quantitative details on the impact of MLPPP on CPU utilisation. So the best option for you is to do some baselining within the lab: start with an unloaded box with two separate T1s, pass traffic over them so that they are both fully utilised and then note CPU utilisation. Then, enable MPPP over these, pass traffic over the multilink interface so that it's fully utilised and then note CPU utilisation. That should give you some idea of the incremental impact of such interfaces. You can always do things such as disable fragmentation when using MLPPP which does reduce CPU utilisation.
Having said that, the NPE-400/NPE-g1s are pretty grunty and should be able to handle a few multilink interfaces. It comes down to how many of these interfaces you are expecting to use...
Hope that helps - pls do rate the post if it does.

RAS access via multilink PPP

I need to establish RAS access to my network via an ISDN PRI line. Most users will be single POTS line users but I'll also need to allow bundled POTS line users via Microsoft multilink PPP. I'm planning to order a Cisco 2811 to handle this using a NM-1CE1T1-PRI module for the PRI and a PVDM2-24DM for the calls. Will this setup handle my requirments?

I have 20 leased line with 256 kpbs sharing on 2 E1 links on the module NM-1CE1T1-PRI (1-Port Channelized E1/T1/ISDN-PRI Network Module).
Now we are migrating those 20 line to 2 mbps leased line, i wanted to know that using PVDM can i used the existing 20 lines as backup isdn line ?
We use RAS for dialup and want to remove RAS device so my question is can i use the cards mentioned above so that 20 locations can dial in with on the present E1 card without using patton RAS?

RV320 and Multilink PPP

Has anyone attempted to achieve something like this:
On the remote site, a Cisco RV320 Router, connecting to two DrayTek Vigor120 xDSL modems through the two Gigabit WAN ports, which connect to two xDSL links.
Ignoring the Core end of the xDSL (which I can make support Multilink PPP), has anyone ever imagined/tried/succeeded to run multilink PPP originating in the RV320 router or similar ( the LAC), transiting the two xDSL links and terminating on the LNS at the Core end of the xDSL link?
Sorry its a bit off the wall, I think I may be asking a lot to make this work, but you have to try!
Thanks,
Jim

Bump!...anyone out there with ideas?

Multilink-PPP

Hi,
i want to make my Archlinux work as Multilink-PPP server.
i played with MPD http://mpd.sourceforge.net/, a FreeBSD Multilink-PPP daemon, and it was easy to let it bundle to L2TP-Connections to a single link.
But doing the same with Linux seems to be quite harder, can you help me?
The-Master

the only way that i know to set up a multilink ppp in linux is to use pppd and set the mp option in the peer file, you can probably find a lot more about it by checking the pppd man pages and you will also need to find a l2tp module for the kernel. search google for it.

I have 12 core with Quatro 4000 and 5770, I want to use dual monitor setup, monitors are NEC with Spectraview-II. How do I connect? 4000 only has 1 Display Port and 1 DVI. 5770 has 2 of each, if I use both 5770 Display Ports, does the 4000 contribute?

I just bought a 12 core with Quatro 4000 and 5770, I want to use dual monitor setup, monitors are NEC with Spectraview-II. How do I connect? 4000 only has 1 Display Port and 1 DVI. 5770 has 2 of each, if I use both 5770 Display Ports, does the 4000 contribute any work at all? I read where on a PC they would work together, but on a MAC they do not.
I read that Display Port has higher band width than DVI, NEC monitors for best performance they recommend using DIsplay Port.
When I was setting this up I looked at a Nvidia Quadro 4000, unfortunately it was for PC, it had 2 Display Ports, in the Mac version they reduce it to one. I did not think there could be a difference.
Mainly want to use it for CS6 and LR4.
How to proceed???
I do not want to use the Quadro 4000 for both, that would not optimize both monitors, one DP and 1 DVI. Using just the 5770 would work but I do not think the 4000 would be doing anything, and the 5770 has been replaced by the 5870.more bandwidth.
Any ideas, I am a Mac newbie, have not ever tried a Mac Pro, just bought off ebay and now I have these problems.
As a last resort I could sell both and get a 5870. That would work, I'm sure of that, it's just that I wanted the better graphics card.
Thanks,
Bill

The Hatter,
I am a novice at Mac so I read all I can. From what I understand the NEC monitors I bought require Display Port for their maximum performance. The GTX 680 only has DVI outputs. Difference from what I understand is larger bandwidth with the DP.
You said I have the 4000 for CUDA. I am not all that familiar with CUDA and when I do read about it I do not understand it.
A concern I have is, that if I connect the 2 high end NEC monitors via the 5770, using it's 2 Display Ports I would have nothing connected to the 4000. Is the 4000 doing anything with nothing connected? I read where in a PC system the 2 cards would interact but in a Mac system they do not.
Bottom line, as I see it, the 4000 will not be useful at all to me, since I want a dual monitor set-up.
So far the 5870 seems the best choice, higher band width than the 5770, and it has 2 Display Ports to optimize the NEC monitors.
I'm not sure how fine I am splitting hairs, nor do I know how important those hairs are. I am just trying to set up a really fast reliable system that will mainly be used for CS6 and LR4. Those NEC monitors are supposed to be top notch.

What Monitors WILL work with the Mac-Mini?

If the new Mac-Mini does not put out analog video and Apple does not state this, what monitors will work with it?

I was able to get an Apple Studio Display to work via the adapter in the Mac Mini box combined with that huge DVI to ADC adapter they had sold me years ago. In the Apple Store I really had to press them to assure me my display would work as they told me they'd charge me a re-stock fee if I had to bring the Mini back. I pressed the point that Apple should know if a monitor it made works with a computer it made. The rep asked around and we both searched the web and then she was able to confirm it would work. They really need a list of acceptable monitors. If anyone locates such a list, please let us all know!

How do I set external monitor to work with my G4 iMac?

I just bought a 22" Proview LCD monitor to use with my iMac b/c it's monitor is pretty much gone. It did not work for six months, then came on for 1 day and went out again.
Long story short, since I've hooked up the new monitor when I print in iPhoto the pictures come out too dark and the color is not what it used to be.
How do I fix it so my monitor's calibrations match the original? Or, whatever I need to do to fix it.
I print a lot of pictures and I need this to work correctly.
Thanks.

Snoot, welcome, your new monitor just needs to be calibrated. From the finder under the Apple scroll down to System Preferences, Click the Desktop & Screen Saver icon and set the desktop picture to a Medium Gray.. You can change this back when you are done. Now go back by clicking Show All and click the Displays icon, then choose Display in the upper tabs and set your preferred resolution. Set your monitor brightness at about medium (if there is one) and at Colors choose Millions. Now choose Color from the upper tab and select Calibrate. Choose Expert Mode at the introduction and follow the on screen instructions. After making all of the Hue,Value and Saturation adjustments your must save the setting back to the Display profile.
Also some applications have monitor selection in there preferences, so just make sure that you choose your present Display Profile for that particular application.

I just purchased a 28" 4K monitor to use with Premiere Pro CS6 in WIndows 8.1 and the fonts are super tiny.

No matter what settings I choose, the fonts on the display are impossibly tiny. The menu fonts at top are readable, but everything else feels like I am taking an eye exam.
Is this fixable, or do I need to return the 4K monitor and fuhgedaboutit?
Since I am doing some shooting in 4K, I thought this monitor would make sense.
If in fact it can't work with PP CS6 on WIn 8.1, what is the best recommended monitor to use with PP CS6?

I understand your issue and I don't have a solution for you. Sorry. In Premiere Pro CC 2014, you can increase the size of the fonts in the Project panel, but not in CS6.

You don't say what sort of Inputs it has available, but if VGA, DVI or HDMI then yes, you might need to buy an adapter of some type though ...
