3550 smi and xls randomly slowing network down

Please help i have over 50 3350 xl's and smi Cisco switches, which at random time on different floor in a 20 story building slows network down. The switches are not struggling traffic or reporting errors. I have logged many calls with cisco and together we configed udld loopguard spanning treeport fast and upgrade all devices to the latest ios. but after doing tests by transferring 1 gig data from client building to hosting facilty some switches take 50% more time to tranferrer the data. The swtiches are gig stacked in pairs of 3 which connect to 2 4000 switches via fibre. Any ideas what else this could be. ? I have noticed that the gig stacks to each other are mauanlly set to half duplex. is this normal or should i false to full duplex ?

It shows Spanning-tree Protocol failures in some Catalyst 3550 models

I have just upgraded to Maverick and now I cannot find certain files. These JPG's are there on my hard drives however . I rely heavily on the search facility and this is slowing me down.

I have just upgraded to Maverick and now I cannot find certain JPG 's . These files do exist however I can find them manually . I rely on the search facility and this is slowing me down, I am having to trawl through stuff to find the file I want , before I would put in part of the title and the machine would find it.

QoS and WMM settings slow internet down when enabled

Ok, so I recently upgraded to a Linksys E3200. I am trying to get the QoS to work properly. I know that it is supposed to prioritize network traffic, so that if I have busy traffic but I am playing an online game, it should keep my gaming from stuttering while slowing other traffic down. It's a great idea in theory.
The problem is that every time I enable QoS everything slows down dramatically. I had a 200MB download that was going to take 5hrs with QoS enabled, that took 10min with QoS disabled. And with QoS enabled I can't even watch a youtube video without it pausing to buffer every 10 seconds. And that was the only PC/device using the network at the time. Again turning off the QoS WMM option solved the problem. I have noticed this problem with multiple routers and brands and usually just disable QoS as soon as I set up a router, however I heard that I won't get the full benefit of 300Mbps without QoS enabled. Does anyone know if that is true?
I don't have any special Voice over IP needs, or video streaming etc. and I rarely am using multiple network devices at the same time. Is there really any reason I should enable QoS?
Also I never really play with the settings for QoS, I just figure that since it comes enabled by default it should work for the average consumer. Does anyone know if changing the settings will help?
Thanks for your help
Solved!
Go to Solution.

So leave it off since it's not working for you. FWIW I have never found it to be of any benefit. The router works fine without it.

Kernel 3.9.9 and 3.10 - Slow network, forcedeth kernel module lock up

Hi all,
I updated for the first time in ~60 days uptime (I did the /usr migration without a hitch) and now I am running in a frustrating problem with my network...
When I start a large copy (using gigabit) the transfer starts off at ~ 3MB/s then slowly drops until it stalls. I get this in my dmesg:
[49257.355089] forcedeth 0000:00:12.0 eth1: Got tx_timeout. irq status: 00000020
[49257.665732] forcedeth 0000:00:12.0 eth1: nv_stop_tx: TransmitterStatus remained busy
I looked up this error and most references I have found date back to 2008 - 2010.
Does this seem like a kernel bug, or is it more likely I have something configured wrong?
Thanks,
Sam

On the Add-a-Printer pane, the top box is the protocol choice. Mine defaults to Appletalk, but there are six other possibilities and I have several AppleTalk printers so I don't know if that is the default.
Unless you know it is an AppleTalk-capable printer, the best choice by far is Rendezvous/Bonjour. Then wait a quarter minute and see if it can find any printers using that protocol.
hp web site says that 3990 is not enough to identify a specific product.

I have a 1st generation time capsule and an extreme b/g. Is the extreme slowing the network down

I have a 1st generation time capsule and an appe extreme b/g. Is the extreme slowing the network down? Should I dump it an get the new n version?

yes it is likely to be slowing down the network because you are using 802.11b/g
from what i recall with b/g a slow client can slow down the entire network to that clients speed.
this was the major improvement with 802.11n and Mimo. each client can be connected to the access point without affecting your speed to the rest of the network
its reccomended to get all new "N" equipment if you have the budget for it. some of those old airports and time capsules can still be worth something on amazon marketplace so you might be able to sell them
if you want to create / join / extend a netwowrk your going to probably need all "n" based equipment.
buy the new 4th generation time capsule or the new 5th generation airport they have better stronger radios
in the mean time configure your base station router to a high multicast rate, so it will prevent devices connecting to it at 1-2 mbps speeds and slowing down your network
if you have an apple care covered mac remember the airport / time capsule rule. all airports and time capsules purchased 2 years before you bought your mac to the 3 years of apple care covers them. if you do not have apple care then the standard warranty applies

Random Slowing and deleting files..

Hello,
i have some problems with my Xserve. First when we try to delete files on the Xserve from a network G5, the deleting is direct (no move to trash) and very very slow, making all the xserve going slow...
Sometimes (randomly) all the server go very slow .. i have verified. Network is ok and i have just retrospect running. Copying a file can go as long as 2 hours for 100 megs and all is very slow.
any idea ?

How full are your storage devices?
It sounds as though your disk access could be slowing down.

Time machine running slow and slowing network access

I have had and continue to have issues with wifi on my MBP. Those are pretty well summarized in https://discussions.apple.com/thread/5535320?start=30&tstart=0. I've been able to make mt system usable with some of the less dodgy workarounds in that thread ( like keeping a ping on my router running )
That thread really doesn't mention the issues I've been having with time machine though, so I thought I'd bring this up here. Whenever time machine starts up, Safari and mail become unresponsive. It's worst when TM is "preparing" of "cleaningup", though barely usable during the actual backup. Mostly, I can work around that too, but occationally, TM will find GB of data to be backed up and lock up my mac for a day. Here's a recent example:

This is on an AC router. My peak throughput shows 19 Mb/s on menu meters, so, not great, but not this slow. Mostly, the network activity is nothing with short bursts of higher throughput.
I'm hoping this will be addressed in 10.9.2. In the mean time, are there any workarounds to get past this issue short of turning off TM?
Thanks,
Horst

These instructions were taken from Mac OS X Hints at:
http://hints.macworld.com/article.php?story=20050302225659382
The Unix program dd is a disk copying util that you can use at the command line in order to make a disk image. It makes a bit-by-bit copy of the drive it's copying, caring nothing about filesystem type, files, or anything else. It's a great way to workaround the need for Norton Ghost.
Normally, in order to make a disk image, the disk you're copying from has to be able to spin up and talk -- in other words, it's OK to make a copy if the disk is healthy. But what happens when your disk is becoming a doorstop? As long as it continues to spin, even with physical damage on the drive, dd and Mac OS X will get you out of the fire.
We had a situation recently where a friend sent a disk to us that had hard physical errors on it. It would boot in Windows, but then it would hit one of these scratch marks and just die. We fired up dd, and it started OK, but stopped at the same physical error location -- complaining about a Hard Error.
So the workaround was to designate the dd mode as noerror -- which just slides over the hard stops, and to add the mode sync, which fills the image with nulls at that point. We did it on BSD Unix, but as long as you can get the hard drive attached to your Mac, the command is the same:
dd bs=512 if=/dev/rXX# of=/some_dir/foo.dmg conv=noerror,sync
The bs=512 designates block size, and the if=/dev/rXX# is the UNIX path to the actual disk device. Make sure that the chosen directory (some_dir) has enough room to take the entire disk image -- which will be equal to the size of the drive. Since dd doesn't care about the contents of the drive, it copies every bit on the thing, so you get an image equal to the disk's capacity. A really big file. One workaround is to put it on a RAID array.
Once you've established the disk image (in this example, foo.dmg), you're almost home. Here's where your Mac OS X box is far and away the best thing to have. In this example, the dd output file is foo.dmg. You have to realize that this is an exact copy of a busted drive, but the "holes" are filled with nulls. As long as the damage isn't to the boot sector, though, when you double-click on it, Mac OS X mounts it without breathing hard ... who cares if it's FAT32, NTFS, whatever.
Due to the size of the image that we were copying, we put it on a RAID array, and had to access the image over the network -- it still mounted fine. In straight UNIX, if you try to mount a disk image, it complains that there is "no block device" and fails. Once your image is mounted, it appears in your Finder, and then it's easy work to retrieve the critical files from the image -- usually things like .doc files and .xls files and the lot.
Finally, since your disk is actually dying, once you have your image, you can drop it to tape or something and you've not only recovered your files, you've made a viable backup as well. Once again, that which destroys a Windows box becomes a play thing to a Mac OS X box.

DT files dropped into Finder and whole Mac slowing down

Hi, I don't really know where to start my thread, so apologies if this is not the right place. My problem is that my Mac has slowed right down suddenly and my various DT files will not reappear (except for a few) when I restart. In fact, the DT is empty until I click at random, after which some of them appear. This all started when I did something that was probably unwise. I wanted to make a copy of my Photo Library for my external drive, so I created a file on the DT to put them in but this operation (about 5000 pictures) never really finished and I can see that these photos are stuck in some kind of DT limbo. What I may have done is drop them into the HD by mistake while I was dragging them to the external disk (?). I think that is what has bunged everything up but I have no idea what to do. I am trying to delete them within Finder but each time I do this I get a message for each individual file saying that the file is being used in another application and that deleting it might damage the other application. I can delete them, except for a few. In any case, this means clicking another 4500 times to delete each one individually, which is a bit beyond me. If anyone can help or direct me to another post, I'll re-post there.

Good! Available 194GB You are nowhere near the 10% mark.
Ok.. since things are slowing down... try booting from your install disk and run the Disk Utility app to check the startup disk for errors. You will need your install disk to do this.
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
*"like when I first turn it on, it takes forever to go to the users box."*
Open System Preferences/Accounts and select the Login Items tab.
If there are any applications listed there, delete them.
And go to ~/Library/Startup Items. If there are any files in the Startup Items folder, delete those also.
And see if deleting this file helps.
com.apple.loginwindow.plist
/Users/YourName/Library/Preferences. Drag that file to the Preferences folder to the Trash, empty the Trash and restart your Mac.

Can a Hyper-V machine be made slower and/or emulate a slow network connection?

need to reproduce an issue with a client-server asynchronous communication (a bunch of JavaScript AJAX vs. an OData api), seemingly caused by some race condition in the calculations when the server and/or the network connection
slow down.
Now, the test environment I have is a local Hyper-V machine, so it's all shiny and fast ... I need it to slow
down to verify it.
Is there any known method to (basically) make a LAN Hyper-V machine to behave like a remote server reached though a crawling internet connection ?

The best method I have found for simulating a crapy internet connection is to put a pfsense router between the server and my test PC and setup the Limiter features.https://doc.pfsense.org/index.php/Traffic_Shaping_Guide#Limiter
This can be used to emulate a slow network, latency or even introduce packet loss to see how your applications react to adverse network conditions.
pfsense can run inside a hyperv virtual machine. So you can set it up then change the webserver network settings to be behind pfsense.
If you don't like pfsense you can use any BSD distro that supports Dummynet.http://cs.baylor.edu/~donahoo/tools/dummy/tutorial.htm

Random swich port down and up

Core:4506 x 4
Access Switch: 2950 x 50
i met a problem that almostly all of swich ports down and up randomly. connect with ports are lots kind of laptop and desktop. In one week it appears one or two times.
spanningtree mode PVST. convergence is ok.
VTP mode Transparent.
all vlans Spanningtree root is one of 4506.
network cable is passed testing.

Hello,
do you see any errors on the ports that show those symptoms ? Can you post the output of ´show interfaces FastEthernet´ of one of those ports ?
Also, I understand that all your switches are running their own VTP database, since you have configured them as VTP transparent ? What exactly does your VTP domain look like ?
Regards,
GP

Slow file open and save across airport network

Hello -
I just purchased an Airport Extreme base station and am having some problems. I could not seem to find an answer to this issue in the archives.
I have a small architecture firm and have 3 computers networked together (iBook G4, mac-mini, and Powermac G5). The G5 is our file server. A typical CAD file size is on the order of 10 mb. Since going wireless with the Airport Extreme, opening these files has become painfully slow - 2 minutes for a 11 mb file, for example.
All computers have a strong airport signal (four bars), and internet connection on all machines is fast.
Security: WPA2
Robustness: ON
Thanks for any help you may have to offer.

(I posted this elsewhere, hope this helps you as you did not have any responses. )
Big horrible slowdowns in file transfer over wireless have me pulling my (remaining) hair out.
I had given my Apple Airport base station (b) to my brother in Pakistan after I found a Belkin (g) at Staples for free (after rebates) and have been using it for a while. Not a pretty box but the price is beautiful and it works OK.
My real use for it is for my eMac and a couple of older PowerBooks I keep downstaors as a "music studio" for my music and podcast recording (and transferring upstairs to my server folder over wireless) and web browsing.
All worked OK as I would transfer the files to my PowerBook upstairs (connected Ethernet to a router connected to the wireless router or sometimes directly via Airport connection if laptop was not at my desk). Both configurations worked fine (only limitation being my eMac's (b) speed older Airport speed).
Since 10.4.5 (as that is the last "change" I can see made on my system overall, I have discpovered I cannot even transfer a 3.5 MB file from the eMac to ANY of the other machines. After reading several threads here it seems several people have noticed the HORRIBLE SLOWDOWN if not complete death of Airport usability for file transfer. People are being made to go around changing router settings, channel IDs etc.
That sounds like typical tech support bunk to me. After all, if the channel ID on the wireless router is a problem why is my web browing going on at normal speed but a 120 MB file transfer just told me it will take 2023642128 hours. No, I am not kidding. That is the time it would take to get man to Mars. Someone else was told to hook up the machines over Ethernet. Sure, that works for machines in the same room - and is a bearable temporary solution in that case - but not in an upstairs/downstairs situation. Burning CD-Rs to transfer 120 MB files every time is also not a good way to show off Apple technology.
So, in my humble opinion, some recent update from Apple just broke something in Airport networking or Appleshare. (Much like I have found out that DiskWarrior, a hard disk repair utility will crash after completing a current task unless you downgrade QuickTime from 7.0.4 or something to a lower version. Go figure.)
I love Apple, getting friends to switch all the time, but annoyed at these bugs that basically render standard applications unusable. So far I have not been able to figure out what the problem is.
I already deleted all the network port configurations on the eMac except wireless. Activity Monitor shows 0.1 to 11 kbps speed (yes, that is 0.1 to 11 Kbps not Mbps). No other apps are running, Tried connecting to different machines. All machines can transfer data at high speed except over Airport/wireless.
Hope you can suggest a solution when you find one.

I just upgraded to Maverick on my2 year old Macbook Pro and it has slowed down the computer terribly. All I see is that whirling circle every time I do anything. How do I go back to old OS. Terrible upgrade -- forces you to buy a new Mac!!!!

I just upgrade to Maverick on my 2 year old MacBook Pro and it has slowed down the computer terribly. All I see every time I do anything is that crazy circle going round and round. I don't recommend you upgrading. How do I get rid of it. I believe it forces you to buy a new macbook!!!!

It does not. First things first have you tried restarting?
Try restting PRAM

Try booting up in Safe Mode

Also open "activity monitor" and look and see what is using a lot of processing power.

This is usually indicative of a defective print cartridge. Suspect the black is low in ink or defective. Please check all cartridges.
