Is QoS tools shape good for VoIP?

Hi,
I have MPLS VPN scenario. For MPLS VPN at PE router connecting to hub, I've configured below QoS:
class-map match-any P1
match ip dscp ef
class-map match-any P3
match ip dscp default
class-map match-any P2
match ip dscp af31
policy-map QoS
class P1
priority percent 35
class P2
bandwidth percent 40
random-detect
class P3
bandwidth percent 25
random-detect
Since on the egree PE towords the internet, I'm using subinterface thus, the configuration is:
policy-map cust-qos
class class-default
shape average 256000
service-policy output QoS
interface FastEthernet1/0.8
encapsulation dot1q 8
ip address ...
service-policy output cust-qos
Since the internet access is 256K, I've configured shape average 256000.
My problem is that, during high congestion at internet access, I noticed that on cust-hub my VoIP SIP is having problem to ring to another VoIP SIP within the same hub. Is it because of the shape command ?
thanks in advanced

Hi Maher,
shape average 256000 is to much. The point is, that you have OSI layer2 overhead and layer2 keepalives and such. Lower it to f.e. 240000. You might need to "play" a little with the parameter, as the overhaed depends on average packet size.
Also make sure, that your SIP traffic is marked with af31. Just as a note: Cisco changed from marking voip signaling with af31 to cs3. Take a sniffer and check that proper markings are in place for voip signaling. Or just try
class-map match-any P2
match ip dscp af31 cs3
Hope this helps! Please rate all posts.

Which Performance Monitoring Tool is good for Weblogic?

Please advise me on good performance monitoring software. Budget is no issue.
A typical performance monitoring tool has:
Server monitoring
Application server monitoring
Database monitoring
Web services monitoring
Virtualization monitoring
An example is ManageEngine's Applications Manager
currenty, I want to monitor:
1 - BEA Weblogic server 8.1
2 - Oracle 9i Rel 2
Once I can identify the bottlenecks, recommendation for hardware / software upgrade can be made easily.
Thanks.

Thanks Faisal, I will evaluate this product if full functional trial version is available.
so far I have come to know about these tools:
Applications Manager
up.time
Still not sure which one brings more value to the business.

Setting Up VLAN and QoS for VOIP on SG200-18

We recently purchased the SG200-18 smart switch to replace a Netgear unmanaged switch. We're moving our phone service to VOIP through our local ISP as well.
I've currently got the VOIP phone plugged into Port 17 on the SG200-18 (it's a Grandstream cordless VOIP phone).
I want to put the VOIP phone on a separate VLAN from the rest of the network and optimize the QoS settings so that the VOIP phone has exceptional audio quality even during intense network traffic.
Here's my questions:
1. Do I need to adjust anything on the type of port for Port 17 (since it looks like some form of Combo port)?
2. How do I go about isolating the VOIP phone on it's own VLAN (I'm seeing VLAN and Voice VLAN settings, not sure which one to use; I tried setting a VLAN and broke Internet connectivity to the phone until I went in and removed it)?
3. Do I need to adjust any QoS settings on the switch to better optimize the VOIP phone?
A couple of additional questions about the GS200-18 in general:
1. Do I need to adjust any of the System Time Settings on the switch? I'm in Central Time.
2. Do I need to adjust any of the Green Ethernet/Energy Saving settings or should I stick with the defaults?
Also, a couple of "getting started" side questions to Cisco:
1. I've registered a My Cisco account. What do I need to do to register my switch with Cisco and associate it with my My Cisco account?
2. What are the benefits of taking out a Cisco Small Business Support Contract, and about how much would it cost on the SG200-18 (I ordered it from Provantage)? I'm curious to see if it's worth the money.
Here's my "specs":
Switch: SG200-18
VOIP phone: Grandstream DP715 and 710 expandable handsets
Plugged into: Port 17 on the SG200-18
ISP: Local ISP (Direclynx)
Connection type: 3M down/500k up DSL, moving to a wireless connection coming up which will give us faster speeds
VOIP backend provider: VOIP Innovations
Router: Apple Airport Extreme AC model (I run all Macs and iOS devices and OS X Server on the network, so using the Apple router makes setup easier, since it doesn't QoS, trying to QoS and VLAN at the switch level)
Thanks everyone!

Hello,
Lots of different questions here so I'll try to make sure I don't miss anything.
1. Do I need to adjust anything on the type of port for Port 17 (since it looks like some form of Combo port)?
The way the combo ports work is you can either use the SFP slot for a fiber connection or the copper ethernet port, but not both at the same time. Other then that they just function as normal network ports.
2. How do I go about isolating the VOIP phone on it's own VLAN (I'm seeing VLAN and Voice VLAN settings, not sure which one to use; I tried setting a VLAN and broke Internet connectivity to the phone until I went in and removed it)?
It sounds like you created the VLAN correctly and assigned the phone, however there wasn't anything doing any routing for that VLAN. You would need to have a VLAN capable router or a layer 3 switch so that something would act as the default gateway for the voice VLAN and route the traffic for you. Since there was nothing like this your phone lost it's connectivity to the internet when you placed it in the new VLAN. I don't think the Airport is VLAN capable, but we will come back to that.
3. Do I need to adjust any QoS settings on the switch to better optimize the VOIP phone?
Once you have a seperate VLAN setup for the phone properly you only have to tell the switch what your Auto Voice VLAN is going to be and it will automatically apply recommended QoS settings for the Voice VLAN and prioritize the voice traffic. There are ways to do this manually and even with the phone in the same VLAN however the are considerably more complicated.
1. Do I need to adjust any of the System Time Settings on the switch? I'm in Central Time.
The system time isn't always very important. You can set the correct time zone, however you should know the switch does not have a battery in it to keep track of time, so if/when it reboots or loses power the clock will reset. If you would like the switch to maintain accurate time you should setup an NTP server so the time is automatically updated from the internet. The switch will keep your timezone settings once you save them. Time is mostly important for logging and things like that, so you can configure it if you like but it is not necessary.
2. Do I need to adjust any of the Green Ethernet/Energy Saving settings or should I stick with the defaults?
Green ethernet simply reduces the power usage of the switch slightly, so unless you are having odd issues where ports are disconnecting, I would just leave them at the defaults.
1. I've registered a My Cisco account. What do I need to do to register my switch with Cisco and associate it with my My Cisco account?
There isn't really a way to associate your Small Business devices with your Cisco account. If you ever call in for technical support we will use your Cisco account and your serial number to create a support case, but even then they aren't linked together. If you decide to buy a support contract, that will be linked to your switch's S/N and your Cisco ID, so in a way that would associate them together. Devices being associated with Cisco accounts is something more common with Enterprise equipment, and mainly has to do with technical support cases.
2. What are the benefits of taking out a Cisco Small Business Support Contract, and about how much would it cost on the SG200-18 (I ordered it from Provantage)? I'm curious to see if it's worth the money.
There are a few advantages to a Support Contact. Your switch comes with a Limited Lifetime warranty that includes 1 year of technical support and return to factory hardware. With a service contract you get 3 years of technical support and next business day Advanced Replacement of the switch if it need to be replaced. I just did a quick google search, and it looks like a contract (part #CON-SBS-SVC2) costs about $50.
So there are a few other things to consider however.
As a frame of reference the average VOIP call uses about 64 - 128 kbps max.
Since you don't have a VLAN capable router or a layer 3 switch, a separate voice VLAN may not be an option. You also mention that the Apple Airport does not do QoS, meaning we will only be prioritizing the voice traffic while it is on the switch. When it is passed off to the Airport to be routed out to the internet all of the QoS settings will be lost, and normal network traffic will get the same priority as voice, since that is all up to the Airport.
With one phone the hassle of getting more equipment and setting up advanced QoS isn't really worth it, especially if the link to the internet isn't going to be participating in QoS.
One last thing I wanted to mention is you are switching to a wireless internet connection. I would ask them how their latency and jitter is, as these two network statistics greatly effect voice quality, and usually wireless performs worse when it comes to voice traffic.
I hope this information helps, if you have any more questions just let me know.
Thank you for choosing Cisco,

What is C++ good for?

I think it's kind of weird that Microsoft can't build a class designer that displays manged types in C++. Why is it that C++ always comes last out of all of the languages! I know it isn't the most popular language but still, you begin to feel like Microsoft are trying to shut it off so there are only 2 languages, C# and VB. Over the years I have learned to program in C++ because of the pointer functionality and the sense of control you have over your code. Where as in C# you know less about what pointers and memory are doing and as a result it makes it easier to program in C#.
But then it begs the question what is C++ really good for at the end of the day. There is less and less functionality for it and it's language with many syntax obstacles compared to the easy and quick ways of writing C# code.
I would really appreciate different sides of the debate because then it might help me to realize that learning all about C++ wasn't such a waste of time after all.
Thanks in advance

What is C++ good for?
simple answer: it's the only language you can use to write real programs with (= for a computer) ... all other "programming" languages are some kind of scrippting tools in my eyes
but today they even call html and css a "programming" language ... that's like saying "hey, I'm a chef, I know how to cook water"
it's true, that we should talk about C/C++ and not about C++ alone and it's also true, that there are things in those language which I would like to change... but far less than in C#, Java and VB... oh and by the way: no, it's not complicated,
it's powerful ... with C/C++ you can program the machine! you can decide what it should do! and you know if you're talking about a pointer, a variable, and integer or what ever...
and if somebody is passing a string by value... well, then... this person simply isn't a programmer... that's it ...
so, again... what is C/C++ good for? it's the only way to write computer programs
that's what I think...

Hello,
I am not a PC security expert but that software looks pretty suspicious to me. If you google the name of the software there are a large number of posts from people asking how to remove it and suggesting that it has been installed without their consent.
I suspect that it is adware which hijacks the users browser home page / default search, displays adverts and generates revenue for the owner. It is possible that it also causes other security issues.
I don't know enough about that software to feel confident in telling you that you '''should''' remove it (especially if you are getting value from the service it offers) but I will say that I wouldn't feel comfortable having it running on my own machine.
If you like the software then by all means keep it but I do suggest running a range of antiviurs / malware removal tools. These will run alongside your existing anti-virus software:
* [http://www.microsoft.com/security/scanner/default.aspx Microsoft Safety Scanner]
* [http://www.malwarebytes.org/products/malwarebytes_free/ MalwareBytes' Anti-Malware]
* [http://support.kaspersky.com/faq/?qid=208283363 TDSSKiller - AntiRootkit Utility]
* [http://www.surfright.nl/en/hitmanpro/ Hitman Pro]

If any of these flag easylifeapp as a problem then I suggest removing it.
I hope that helps.

QoS on 7200 LNS for PPPoX

Folks,
I need a little clarification.
We have a set of 7200's that run as an LNS to various PPPoA and PPPoE clients dotted about the place. These are authenticated via RADIUS and exit the router on various VRF's to find their destinations. All works very well.
We are looking at implementing a QoS policy on the 7200 LNS being pushed out via the RADIUS server, which we've tested and know works fine. The question that I have is about how the QoS policy will behave:
The QoS policy will be applied to the various Virtual-Access interfaces as the users connect and will be applied for downloading of traffic specifically. What is the best way to build the policy? The reason I ask is that I'm unsure as to how the traffic will act as it exits the router on the downstream gig ethernet link. Is there a QoS policy that needs to be created on that physical link too?
Has anyone implemented this sort of configuration and if so, what are the lessons learned? Did you go with "bandwidth" for the QoS and shape out 100 percent of the link on the Virtual-Access? I'm looking to ensure throughput in times of congestion, but dont want to police the interfaces down all of the time.
Any thoughts or comments?

Hi Leigh
I was wondering if you can post your comments after you tried setting this up in the 7200.
I am running ver 12.4 and can't get much information around, however I found a couple of posts saying the feature is not supported.
any comments would be appreciated.

Is this program good for first timers or college students?

Is this program good for first timers or college students?

After Effects is a program that can do a simple transition between two still images or produce any composite you have seen in a feature film. The only thing After Effects cannot do is create, edit, and animate 3D models like robots or space ships. You can, however, in concert with a 3D app do anything you have ever seen on the screen and, if you are really creative and talented, probably do something we have not seen yet. You can achieve a successful first project by following these 3 videos: Basic Workflow
It may take years of experimenting and research to create something we have not seen yet. Starting to learn to use After Effects is like having the key to the Snap On truck and access to all the tools. You just have to gain enough knowledge to use them all.

What happended to the Solaris Crash Analysis Tool 4.2 for Solaris 10?

What happended to the Solaris Crash Analysis Tool 4.2 for Solaris 10?
I'm trying to debug a kernel panic under Solaris 10 on sparcv9. I tried the SUNWscat 4.1 package but it core dumps on Solaris 10. I found a blog entry that described the problem and mentioned a version 4.2 fix. That was from May 2006, but I have not found any update sense then. Was 4.2 ever released or is their an alternative tool for Solaris 10 that I can use?

One problem is that those of us who develop Solaris CAT do so as a "hobby" as it's not part of our actual jobs. But he good news is that management gave us the time to get a release out and 5.0 is now available here . We're now planning 6 month releases so we don't have a 5 year delay between updates.
BTW, the Solaris Crash Analysis Tool supports Solaris 10, OpenSolaris/Solaris Nevada, sparc, and x86/x64.
There are so many enhancements and bug fixes that I'd recommend reading the release notes (SUNWscat/docs/index.html).

Setting up Cisco SLM248GT-NA switch for VoIP

Hello Everyone,
We have a Cisco slm248gt-na smart switch in our office that I am trying to configure to support and optimize for VoIP. We have desktops hooked up off the phones in most cases. Are there any config guidelines to optimize the switch so it has proper QOS set and VoIP gets higher priority over data.
Thanks, Kind Regards
Shabbir

Hello Tom,
Thanks for your reply.
We have a pretty straight forward setup. We have 15 Cisco SPA303 phones hooked up to switch and the desktop are connoted via the phone. We have a wireless LAN and a corporate server that servers as a file sharing/vpn type setup. Other than that there are no devices hooked up. We had to implement auto voice vlan feature but were still running into issues like occasional poor voice quality and one way audio type issues. However I did notice something in the configuration menu "Telephone OUI", could you please help us on how to implement that. We are trying to implement best practice to avoid voip related issues that we have been having.
We also see all the ports in trunk mode. Is that the recommended setting or should we change it to access mode?
Thanks, Kind Regards

Is iMovie good for serving as a movie library?

I am new to iMovie.
I have many small video clips from various digital cameras (and the Flip) spanning many years. I would like to organize and browse through them all. Is iMovie good for this?
In other words, does it work like iPhoto? I use iPhoto to organize and view my photos, can I organize all of my videos with iMovie in the same way I can organize my photos with iPhoto?
If not, is there a program that is good for this?
Thanks,

Is Shake as good for miniDV footage?

This is also posted at creativecow:
I want to take on a project that will involve various tools/effects. I'm researching Shake (now that it's $499) and it appears to be the right tool for the job. However, I've only used FCP and your knowledge will be greatly appreciated. (I had previously considered AE and Combustion.)
Here is what my project will need:
1. Rotoscoping - to create a 'clipping effect' of a person walking thru an object/wall. Cleaning up shots that greenscreening didn't cover completely. Fix composited shots where there is improper overlapping.
2. SuperSlow Motion - How slow can I go? Can I go to a stop and ramp back up? Is it smooth?
3. Tracking - for compositing 2d items together. (Using tracking data from someones eyes and applying a paint operation to it. Or creating a sign that would be added to the scene where the camera is moving.)
4. Stablizing handheld shots - I'll try to be as still as possible, but this could be very valuable. (I figure this could begin to look awful if there is too much bounce in the footage because miniDV probably doesn't scale up very much.)
I know Shake can handle these tasks, but I'm questioning how well it will perform with my miniDV footage. Are others using Shake with miniDV? Are they/you satisfied with Shake... is it what you expected?
Lastly, I currently have a one button mouse. The Apple three button mouse seems OK... What do you recommend?
Thanks,
Jon Banker
My machine:
2.0 Dual G5 / 2gig Ram / ATI 9600 pro

Howdy,
I shoot all I do in MiniDV. I am just doing little corporate videos and such. Let me just respond to what I know.
1. We have rotoscoped a car. Me walking toward the car. It turned out pretty good for only spending an afternoon. If you allocate lots of time, you can make it look pretty good with Rotoscoping in Shake.
2. No Experience
3. I have recreated the HP Photo Commercial using the MatchMove Node. It turned out pretty well. It is a little tough to get a Really good Track with MiniDV, but with a lot of patience it can be done.
4. No Experience
I use Shake 4.1 on an Intel iMac. It runs really nice on MiniDV Footage.
Take Care,
Nate

Snow and setting priority for voip voice packets?

I have an engine Voice Box 2 connected to my dual ethernet base station, for voip phone calls using a 1500kbps broadband connection. It all works fine, except sometimes the voice quality of phone calls isn't good - drop-outs occur. Engin support tells me there is a way to configure an airport BS to give priority to voice packet data over other internet data data, and this will improve the voice quality.
Is this possible with a snow BS, and if so how do I do it?

OK, Duane and anyone else. My question has been answered via telephone from Apple Australia, on Thursday 22 Feb 2007 at local time 9.01 pm. The answer is: There is no way that any version of an Airport BS can be set to prioritize voip voice packets over other internet packets of data.
Apple Supporters in other countries may disagree (not a surprise). I've been a Mac user since the first 1984 64K Mac, and I've not been too impressed with Apple phone service during the last 20+ years, so if another Apple tech elsewhere comes up with a different answer I would not be at all surprised.
So, first premise is my voip provider gave me incorrect info. Second one is maybe someone else gave them the incorrect info. One guess and no prizes as to whom this may have been.
Bigger surprise is that Apple seems oblivious to how popular voip phone is going to be in the immediate future, and that Mac users are likely to receive inferior quality voice quality and have no way to improve this by tweaking their Airports.

Dimension tool plugin necessary for Illustrator ?

Hello,
unfortunatley my company bought CS4, but a few employees also sometimes need to add dimensions to drawings similar like in CAD software for engineer drawings possible.
But it looks like that it is NOT working with Illustrator CS4. (although written in Wikipedia, that illustrator closes gap between CAD and pixel basing software.)
Is there any possibility to install plugin for Illustrator or is Illustrator having such tool ?
Thanks for helping !
Jan

I have an AI Javascript that I built for my own convenience, which creates simple linear dimension callouts, as described here.
It is dependendent upon two Graphic Styles and one Paragraph Style which can be added to your documents (or templates) by copying / pasting from the .ai file that is included in the download .zip. However...
It is little unbelievable that Adobe, eliminated dimension tool from Illustrator. Why ?
Illustrator never had dimension tools.
although written in Wikipedia, that illustrator closes gap between CAD and pixel basing software
Whomever wrote that should be horse-whipped. (Or worse, forced to do techish commercial drawing with Illustrator in a roomful of others who are using either Canvas or CorelDraw.) That is probably the worst mis-characterization of what Illustrator is that I have ever heard.
Did my company buy the wrong software ?
Probably. If dimension tools and a few other very common features necessary for techish illustration are a frequent need, absolutely. Illustrator not only lacks ordinary dimension tools, it also lacks:
Reliable snaps.
User-defined drawing scales.
Connector lines.
Callout objects.
Live shape primitives (rectangles, polygons, ellipses, arcs) with geometric parameters (corner radii, etc.) that can be adjusted after creation.
Proper corner rounding / chamfering commands.
Any feature assist for mechanically corrrect perspective construction.
Is there any other software from adope, which is able to work on .jpg picture and using dimensioning, too ?
JPEG is just a lossy compression format for raster images. I don't know what it, in particular, would have to do with what you have described so far (using a mainstream drawing program to make attractive commercial illustration based on line work exported from CAD software).
But unlike most of its direct competitors these days, Illustrator does not provide any features (other than the ability to apply Photoshop filters) for actually editing raster images. It can import a raster image (JPEG or other) and manipulate it as an object (rotate it, scale it, mask it, etc.). But there are no pixel-editing features.
You have not very well described what your company's needs are. But just given your mention of dimension tools as being important and your need for something to "bridge" between working product drawings and commercial product illustration, I dare say you would be far better off with Canvas, Corel Draw, or Corel Designer.
Unlike its competitors, Illustrator has always treated anything the least bit "techish" as if it's something to fear. It's competitors embrace it as what it is: a huge segment of the overall mainstream commercial illustration world. And it isn't just this seeming "technical" vs. "paper doily" aversion. Much of it is simply the fact that Illustrator has never kept up with its competitors in straighforward, no-nonsense path drawing features. Illustrator has always sat too fat-and-lazy on its Adobe label for market share.
People (including myself) do technical/commercial illustration in Illustrator all the time. Most commerical product illustration is of that nature. But in doing so, they constantly employ tedious, cumbersome, and time-wasteful workarounds for the pathetically weak feature set of Illustrator--or they buy add-ons which cost half what they paid for Illustrator all over again. (I've never understood that mindset. No matter how well-done the plug-in, it's never as cleanly-integrated with the overall program as built-in features; and you have to put up with everything that goes along with mission-critical dependency upon add-ons from small third-party providers.)
