High Discard rate on a FW interface

Hi,
I am getting alert on high discard rates on FW interfaces via a monitoring tool. Just want to validate if the packets dropped by ACL's are also contributing to the high discard rate counter? If this is the case what would be an acceptable threshold to set High Discard rate on FW interfaces to insure I do not miss an actual issue regarding high discard rate. "Interface::I-Interface_Performance_CiscoRouter_Ethernet-IF-XXX-XXXX-SEC/4::HighDiscardRate"

Hello,
Well, that would depend again of the enviroment you have there,
As an example I would not focus much on ACL drops logs ( as they are already being denied, altough it will let you know what traffic is trying to reach ur network) but the treshold would be way higher based on the fact that is common to drop a lot of traffic via an ACL.
But I do not have a specific treshold that I could provide as it will depend on the enviroment.

Output Packet Discard Rate strange values

Hi,
I'm getting a lot of alerts regard to Interface High Discard Rate. When i went to see the Output Discard %, the value are not compressed between 0% - 100%. The values show in the following graphic are much higher than 100%.
These are not the expected values. Has anyone experienced the same problem? Does anyone have solution for this?
Thank you,
Rui

Hi,
We may need to get the performance data on the problemtic computer, and check whether the value equal to what we can see on this view.
In addition, as far as I can see, the value does not mean percentage, this should mean how many bits that was dropped per second.

FEX 6800-IA interface high drop rate and high overrun counters combined with slow throughput.

The interface drop rate count arises and the traffic throughput gets down to 15% of the nominal data rate of the 1Gb interface when a server with a 10Gb interface send data to a client connected at 1Gb FEX interface.
How must I configure the interface to achieve nearly 100% of 1Gb?
Client to Server: 100% of 1Gb; Sever to Client 15% of 1Gb
Server ---(10Gb)--- Nexus7010-- (10Gb)--- C6880-X----(10Gb)---FEX----(1Gb)Client

Sorry, yes of course:

HT4914 I have an iTunes library of some 18k tracks. If I subscribe to iTunes Match, can I delete my library from the pc hard drive and then download my entire collection back at the higher bit rate of 256?

I would like to improve the quality of my iTunes library, most of which were ripped at the old 'higher quality' setting and not lossless.
I would consider subscribing to the iTunes Match programme if I would later be able to download my music back on to my PC at the improved higher bit rate stated.
Is there a problem with this?

HT204406 how do I download higher bit rate songs from itunes match to replace the lower bit rate I have on my itunes library?

I have itunes match and I have about 500 songs that were ripped at 128kbps. I have been tolf that I can replace them via itunes match to improve them to 256 or 320?
I have put them into a playlist in my itunes library and I want to know how I can upgrade their bit rate via itunes match. Can anyone help me?

Sid,
With the device connected, click the Summary tab and you will see the "Convert higher bit rate..." option. Set it to 128. See picture below:

IPod not playing re-ripped tunes with higher bit-rates

Since I got my iPod and have more storage I have been slowly re-ripping some of some tunes at a higher bit rate. iTunes doesn't appear to try to sync these songs and re-upload them to the iPod.
What happens is that the song stops playing part-way through the song. My guess is that it is due to the file size of the old (lower) bit-rate, as if it still thinks the EOF is at the same spot even though the file is now larger. It's almost as if the index doesn't get updated properly somehow.
I've tried deleting all the songs on the iPod and even doing a restore, but that doesn't always fix it. Some songs do it, some don't.
I know the rips are good because I can play them all the way through with either iTunes or Media Player.
Any help on getting it to sync them properly?

I assume that I have to re-rip the songs at the higher bit rate, unless there is Is there an easy way to do that without re-ripping them.
Assuming you want the higher audio quality (and not just a puffed up version of the same low quality track) you will have to re-rip from the CDs.
Also, what happens to the lower bit rate songs in my playlists, especially if I delete the lower bit rate versions from my library?
Under certain conditions, iTunes will recognize the CD and ask you if you want to replace the existing versions. Say yes, and the rip process will automatically do the replace.
In case it does not ask, just go ahead and rip, and then do the replacements manually.

BT Infinity 2 and high ping rate

I am having a problem with my BT Infinity2. I am getting high ping rates some as high as 181 ms. I have download speeds of 15 meg and 8-9 meg upload. This is through the router wired to my computer. I was told that I should be able to get somewhere in the region of 77 meg. This is nowhere near and needs to be sorted out.
It doesn't matter what time of day I do the speed test it is always the same. If I try and play my Football Manager 2012 game online I can't as my connection just kicks me back off the steam server. If I try and watch a programme on Iplayer or ITV player ther programmes are fuzzy, blocking and unwatchable, also with the buffering is beyond a joke.

micksea173 not good and you have my sympathy
Try rebooting both the hub and the modem. Run the BT Speedtester to get your IP Profiles and http://www.speedtest.bbmax.co.uk/ to get an accurate speed test. Pings are very dependant on the site you are measuring a ping of 181 for a server in LA could be quite good! If you know how also run a tracert to bbc.co.uk. Post agin with the results and somebody can make an educated guess as to where the problem lies.

How to build a array with high sampling rates 1K

Hi All:
Now I am trying to develop a project with CRio.
But I am not sure how to build a array with high sampling rates signal, like >1K. (Sigle-point data)
Before, I would like to use "Build Arrary" and "Shift Register" to build a arrary, but I found it is not working for high sampling rates.
Is there anyother good way to build a data arrary for high sampling rates??
Thanks

Can't give a sample of the FPGA right now but here is a sample bit of RT code I recently used. I am acquiring data at 51,200 samples every second. I put the data in a FIFO on the FPGA side, then I read from that FIFO on the RT side and insert the data into a pre-initialized array using "Replace Array subset" NOT "Insert into array". I keep a count of the data I have read/inserted, and once I am at 51,200 samples, I know I have 1 full second of data. At this point, I add it to a queue which sends it to another loop to be processed. Also, I don't use the new index terminal in my subVI because I know I am always adding 6400 elements so I can just multiply my counter by 6400, but if you use the method described further down below , you will want to use the "new index" to return a value because you may not always read the same number of elements using that method.
The reason I use a timeout of 0 and a wait until next ms multiple is because if you use a timeout wired to the FIFO read node, it spins a loop in the background that polls for data, which rails your processor. Depending on what type of acquisition you are doing, you can also use the method of reading 0 elements, then using the "elements remaining" variable, to wire up another node as is shown below. This was not an option for me because of my programs architecture and needing chunks of 1 second data. Had I used this method it would have overcomplicated things if I read more elements then I had available in my 51,200 buffer.
Let me knwo if you have more qeustions

[Bug] iOS 5.1 missing covers after "convert higher bit rate songs to" with iTunes 10.6

All my music has covers in iTunes Library. But after i updated to iOS 5.1 they are missing on my devices.
It happens every time i check "convert higher bit rate songs to 192/256 kbps" on iTunes 10.6 (40) on my Mac.
On the screenshot (iPad 2010 running iOS 5.1) Bon Iver's album copied by default settings, and Coldplay's album converted to 192 kbps.
BTW on my old iPhone 3G (iOS 4.2.1) all covers are OK even when convert feature is ON.

I have solved it by unchecking (momentaneously till apple fix it) the "Convert higher bit rate songs" option.
I know that it need more space but i don't have too much music synced so.. it isn't a problem for me..
I have this problem because i'm using the "manually manage music and videos", i'm not using the auto sync option because iTunes always try to copy my new apps to my mac even having that option unchecked...
Now we have iCloud... i don't know why apple still have not deleted this feature!
Anyway... i have solved it momentaneously.
Apple.... come on!

ITunes 7 and Shuffle:"Convert higher bit rate songs to 128kbps AAC" broken

This has become unusably slow in iTunes 7. Is this fixed yet? Does anyone have a workaround?

I have the same issue but with my iPad 2 and iPhone 3GS. Songs play fine in iTunes. If is uncheck Convert higher bit rate songs to 128kbps AAC the no more scratching sounds on my devices.

Cannot create slideshow with high frame rate

I have just bought QuickTime Pro version 7. I am using Windnows XP SP2 on a Pentium D machine.
I am trying to create a movie with still images I captured from my digital camera. I created a 10 seconds slideshow and set the frame rate to 30 frames per second. I then saved the file as a Quicktime movie. When I played the movie with my QuickTime Player, I could see actions for the first two seconds only. After that, the picture didn't change eventhough the progression bar was moving. Once the movie reached the end, the player then changed the frame to show the last picture of my slideshow.
In short, only the first 60 images are shown in the first 2 seconds. Then the slideshow was stuck with the 60th image, until it changed to the 300th image at the very end.
Does anybody has the same experience? Did I do anything wrong?

One more thing. If I set the frame rate to be less than 10 frames per second, it works fine. It just won't work with high frame rate.

Gx620 HDMI higher refresh rates

Hello,
I've bought a Samsung SyncMaster 2233rz to get a lower inputlag and higher refresh rates. GeForce 9600m GT doesn't have a DVI-D port, thus I'm using the HDMI port with a DVI-D adapter as the monitor only has a DVI-D port. I've read you couldn't get a higher than 60hz signal from the graphics card through HDMI for some reason (..it being a mobile card). I'd imagine it has something to do with the bandwidth, but so far I've managed to get atleast 1680x1050 @ 75hz. It stutters sometimes, but quite rarely.
The refresh rate options are very limited as I use Windows 7, which reads the EDID-information from the display. Nvidia control panel registers the connectors as HDMI - HDTV. I've tried editing the EDID-informations and use powerstrip and such programs to get a higher refresh rate, but so far I'm stuck at 75hz. I wouldn't mind lowering the resolution to get atleast 100hz refresh rate, but so far I've had no luck with it. Have any of you managed to get a 100hz refresh rate from gx620 (through the vga-port perhaps)?

Refresh rate is actually a term for analog CRT monitors, not digital monitors.

HT1535 How do i convert higher bit rate songs to 128 kbps AAC

I am trying to sync selected songs to my Iphone 5 from my itunes library. I have recently taken my computer to be fixed and all of my music documents were taken off but the files were replaced shorty after. I re-downloaded itunes and it is up to date. My iphone is also on the ios 7.0.4. Whenever i plug my phone in to be synced it never goes past the "waiting for changes to be applied" step. While my phone was still connected i went to the "On this iphone" tab and clicked the autofill button and a message came up that said i must convert higher bit rate songs to 128 kbps ACC to allow the songs to be copied to my iphone. How do i do this? Also, once this is done will it solve my problem with transfeering my songs from my library to my iphone?

Using the "Convert higher bit rate songs to 128 kbps AAC" feature...

I recently discovered the "Convert higher bit rate songs to 128 kbps AAC" feature and used it to copy my entire 70 GB music library to my 64GB iPad. The music library now occupies only 45 GB. Awesome!!!
Unfortunately, the whole process took well over 24++ hours on my quad core Windows 7 computer (takes about 6 seconds per track). Questions:
1. Is it possible to speed up the process? Even though I am using iTunes 64-bit version, it seems that at no point is more than a single core being used at 33%. Seems to me like overall 8% of the CPU (33% / 4) capacity is being used for the conversion and 92% is being left idle. Is this just bad programming or is there anything I can do to speed up the process? Others see similar problems?
2. Now I have already started dreading the day, I need to restore my iPad (e.g., when OS version 4 becomes available). I would hate to have to do this process all over again. Should I need to restore my iPad, is there anyway I can force iTunes to back up the 128-bit AAC versions on my computer and restore it up from there?
Any insights into both these questions will be deeply appreciated.
Cheers,

Thanks for the response.
So, I am wondering why iTunes uses only 8% of the processor power in converting the songs.
Possible reasons not to grab more of the CPU power (1) maybe the process is I/O bound due to all the writing, and is not processor limited? (2) since conversion is almost always a background program, and the user will typically have other things going on, maybe it intentionally limits CPU use?
I ran a few quick experiments (out of curiosity) and think the answer is #2. No apparent technical reason but potentially a limitation introduced by Apple's engineers to maintain a good user experience (for some people at least). I fired up 4 instances of dbpoweramp and ran multiple conversions and found that the process goes faster than what iTunes can do by an order of magnitude. With luck, someday Apple will have an option for users to select how much of processor bandwidth to be allocated for the conversion.

Perf. implications of high frame rate

What are the performance implications of using a high frame
rate in Flex. Our designers suggest that a frame rate of 60fps is
smoother animation. They are creating Flex components with Flash
CS3 and want to use the higher rate and use them in Flex.

As you might expect, a higher framerate is going to consume
more of the CPU. It's pretty much that simple. Some end user's
computers may not be able to keep up with the framerate and their
experience will be less smooth, probably less smooth than if you
used a smaller framerate. I suggest you experiment.
