(High Ip input) on My router , I need to troubleshoot why CPU is high !!!!
(High Ip input) on My router , I need to troubleshoot why CPU is high !!!!
=================
i have a cisco router 7200 NPEG2 processor , worked as LNS for PPPOVPDN circuits (Router for ADSL clients)
i have "high ip input on my processor" and there is alot of differnce on my router between operations done by cef and operations done by router cpu
as an example , lets make show cpu process sorted
CPU utilization for five seconds: 67%/54%; one minute: 67%; five minutes: 68%

=====================
as we see above , we have high "IP Input" about differnece in cpu =67-54=13 % , which is high value process in software .
i follwed the article here :
http://www.cisco.com/c/en/us/support/docs/routers/7500-series-routers/41160-highcpu-ip-input.html
i check and found that my router is fine ,
no arp calls.
no routing loops.
no flapping links.
i checked that my router has cef enabled and no enormous routing protocol updates
i found that i have big differnce between hardware & software process on the router which is 13 %
but when the traffic is more and more , the cpu reach reach 93 % and begin to have drops.
i just want to ask , how can i debug the operations that are done on the cpu processor of the router ???
i mean that if i know that traffic , i can estimate and know the problem that increasing my cpu !!!
another question :
how to debug the packest that has a ttl exceeded 50 or ttl exceeded 100 ?????
i dont wan tto make debug ip packed , because i have a huge traffic and it will let my router hanged due to large debug !!
===============
righ now i will post my router config and some verification:

Help needed to troubleshoot why my MacBook Pro repeatedly drops wifi connection
We run Mac & PC laptops, iPhone, iPad on occasion, with ATT DSL, 2Wire 2701HG-B Router. First 6 months of enjoying my Mac, no trouble. Then things started to go south. Been dealing with this problem of dropped internet connection for over a year. Got a new router--the 2Wire 2701, finally got a new phone line put in from the outside to inside. It now seems like the MacBook Pro drops the signal far more than the PC. It seems worse when I'm at my desk, which is only a room away from the router. It can drop the signal about every 3rd or 4th click on the internet. The Networks Diagnostics will show red buttons on the Server and Internet. Been testing other areas of the house, and find it seems better in these other areas, dropping far less. Hard to tell, because the problem comes and goes, like the sun. iPhone has dropped connection on occasion. iPad has occasional slow download of YouTube. Neither of those are troubling.
I tried checking with the Airport Utility, but it tells me it can't find any Airport. I obviously understand very, very little of this. Any help would be appreciated.Which os are you using?
Change your router channel. Sometimes this is all you will have to do.
Power cycling the router. Read the router's user manual or contact their tech support for instructions.
System Preferences/Internet & Network/Network
Unlock the padlock
Locations: Automatic
Highlight Airport
Click the Assist Me button
In the popup window click the Diagnostic button.
System Preferences/Network- Unlock padlock. Highlight Airport. Network Name-select your name. Click on the Advanced button. Airport/Preferred Networks-delete all that is not your network.
Place a check mark next to "Remember networks this computer has joined." Click the OK button and lock the padlock. Restart your computer.

I'm trying to open the latest i-tunes but it keeps saying I need quick time 7.5 or higher
I'm trying to open the latest i-tunes but it keeps saying I need quick time 7.5 or higher (which I do) and I have no updates available for quicktime
QuickTime 7.5.5 for Leopard - http://support.apple.com/kb/DL27
QuickTime 7.7 for Leopard - http://support.apple.com/kb/dl761
= New version of Quicktime installed but application reports it needs to have that version installed =
Open Application > Utilities > System Profiler and check the Quicktime version in Frameworks vs. the version in Applications. One person had re-installed their operating system. It had kept the newer Player application but had reverted to an earlier version of the underlying support framework files which many applications utilize. Re-installing Quicktime 7.7 took care of the problem. Do this manually, not with Software Update.
Installation get stuck at "configuring installation" - https://discussions.apple.com/thread/2592979?threadID=2592979 - uninstall Quicktime before installing. -
I want to set up the Time Machine and I would love to use the Time
Capsule but since I already have a wireless router I need suggestions on
what other
external disks Apple could recommend to use with the Time Machine and
how to configure that disk.
A complication that I need to resolve is the fact that I am using Vmware
Fusion to be able to use Windows on my Mac. Now it seems that Time
Machine is not backing up my files
on that virtual Windows without additional configuration and my question
is whether you can advise me here or whether this is only a matter for
the Fusion virtual machine.If you want to use Time Capsule you can.. you simply bridge it and plug it into the existing router.. wireless can be either turned off or used to reinforce the existing wireless.. eg use 5ghz in the TC which is much faster than your 2.4ghz.
You can also use a NAS.. many brands available but the top brands are synology, qnap and netgear readynas series. These will all do Time Machine backups although how well always depends on Apple sticking to a standard. There are cheaper ones.. I bought a single disk zyxel which was rebadged and sold through my local supermarket. It actually works very well for TM at least on Snow Leopard. Major changes were made in Lion and again ML so do not instantly think it will work on later versions. I haven't tried it yet with those versions.
Any external drive can be plugged into the mac. Use the one with the fastest connection or cheapest price according to your budget. USB2 drives are cheap and plentiful. But no where near as fast as USB3 or FW800. So just pick whichever suits the ports on your Mac. Interesting Apple finally moved to USB3 on their latest computers.
TM should exclude the VM partition file.. it is useless backing it up from Mac OS side.. and will slow TM as it needs to backup that partition everyday for no purpose.. TM cannot see the files inside it to backup just the changes.
You need to backup windows from windows. Use MSbackup to external drive.. if you have pro or ultimate versions you can backup to network drive. But MSbackup is a dog.. at least until the latest version it cannot restore the partition without first loading windows. There are about a zillion backup software versions for windows.. look up reviews and buy one which works for you. I use a free one Macrium Reflect which does full disk backups and is easy to restore.. to do incremental backups though you have to pay for it. -
I'm trying to sync a 4s so that it can be activated w ATT...my computer says that I need to have 11.1 or higher in order to do that but when I download from the itunes site nothing happens and I still can't sync phone...what am I doing wrong?
The screen that says "Download Now" also shows the proposed iTunes version number (in the box below):
Be sure it indicates 11.1.3.
If it is, here's further troubleshooting:

I've installed bootcamp 4.0 on my iMac 27. Everything works superb, but for playing need for speed run or battlefield 3 I need catalyst driver 11.7 or higher. How can I update my graphics? Is there a possibility except waiting for a new bootcamp version?
But how do you install the drivers if Bootcamp is running interference?
Bottom line, I'ev tried to install three different versions of updated ATI driver sover the last few momnths and on each and every occassion have ended up with the original Bootcamp driver. A number of current games are unplayable on a Mac running Bootcamp as a result.
And if I can't run the software I want, then Bootcamp is as useless as boobs on a bull. -
What is the best charging cable for the iPad Air (that is not made by Apple)? I need a long cable (over 6ft or more). I also need the cable to be of high quality and the cord part of the cable to be made of strong material. Apple does not make one this long. Is there a cable out there that is sturdy like this and is safe to use?
yes, but I'm trying to use my iPad to type notes (using pages) and I have the smart case which I use as a stand. I need a cable long enough to fit through the back of my desk and the charging brick for the iPad won't fit behind the desk. I have to put it on the floor and then the apple cables aren't long enough to reach.

My Macbook Pro tells me I need OS X 10.5 or higher to install essential software, but I already have Yosemite (10.10.1). What is going on?
This is it. Programming was done by idiots. People at schools IT department 20 or so full time positions know less then kids at Best Buy GeekSquad minimum wage part time, don't know or even want to call to find out. They just sit there and ask if the antivirus is upto date, I cant install your software that check the antivirus, "ITS NOT THE ANTIVIRUS". Three weeks and as always I have to find the fix myself. My god, why do I work for my money when I can just sit and collect it. Sorry for the rant.
This fix works and needs to be loaded on the campus network. -
Cisco 7609 router received higher traffic than upstream provider router is sending
Hi all,
I have a Cisco 7609 router that connects to our upstream provider router using 3rd party DWDM Fiber backhaul provider.
The upstream provider router is a Juniper router that had capped our port speed to 1.1Gbps, the backhaul provider didn't capped our port speed and the maximum speed is 2Gbps since it's a 2x1Gbps port channel interface.
I have noticed that our 7609 router able to receive traffic that exceeds 1.1Gbps, and the highest traffic able to received is 1.3Gbps and more.
I have crossed checked the MRTG graph provided by our upstream provider as well as our PRTG graph and indeed we are receiving higher bandwidth than our upstream provider is sending.
I'd like to know if anyone know how it is possible to receive traffic that is higher than what the neighbor router is sending?
RegardsHi at all,
We found a solution for this Problem !!
We always and always got this error:
%PQUICC-1-LOSTCARR: Unit 0, lost carrier. Transceiver problem?
The problem was the cable! The following pin-out is required:
1 ----- 1
2 ----- 2
3 ----- 6
4 ----- 5
5 ----- 4
6 ----- 3
7 ----- 7
8 ----- 8
We used this and the fault has disappeared!!
The only problem that still exists:
After the first connection the router must be rebooted because otherwise no more additional session is established.
Thanks for all answers.
Regards,

Hi I just got my iPad 2 and updated it to ios7 . Here is my problem: my Chinese input doesn't work , I need to restart every time . Is it the problem of the iPad? Or iOS 7??
Hi Eric Ferguson,
Thanks for using Apple Support Communities.
For troubleshooting on this, take a look at this article:
iTunes: Specific update-and-restore error messages and advanced troubleshooting
http://support.apple.com/kb/ts3694
Error 13, 14, 35 and 50 (or -50)
These errors are typically resolved by performing one or more of the steps listed below:
Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting.
Put a USB 2.0 hub between the device and the computer.
Try a different USB 30-pin dock-connector cable.
Eliminate third-party security software conflicts.
There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. Your default packet size being set incorrectly can cause this error. Contact the manufacturer of the software that installed the packet-size modification for assistance. Or, follow this article by Microsoft: How to reset Internet Protocol (TCP/IP) to reset the packet size back to the default for Windows.
Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online.
Try to restore from another known-good computer and network.
Best of luck,
Mario -

I Have an old single 2.4 GHz router. If I upgrade to a new high speed router will I get improved streaming of videos?
thanks.It depends on what's rate limiting - if it's your wifi maybe, if your internet connection is slow the router won't make a huge difference though some products are better with poor lines.
Can you hook up a laptop to the router via ethernet and test the internet speed via speedtest.net? -

After using my computer for some time, CPU usage climbs to about 90% (ca. 65% user / 26% system) and fans run at high speed, but there is no processes that seem to use CPU (other than Activity Monitor itself ~1%).
This has happened a few times recently. It happens when I've used my computer for some time, hours or a couple of days (I usually put my computer to sleep when not using it but rarely shut it down). I've tried to quit all running apps incl. Growl, Dropbox, and anything that could be responsible to this but with no results. Putting computer to sleep for a long time doesn't help, cpu usage will climb instantly after wake up. Restarting system is the only thing that helps.
Most of the time I use my laptop with external monitor, lid closed and connected to power supply. When experiencing this, opening the lid causes fans to slow down, but CPU usage remains high and battery drains quick.
Any ideas what might cause this?

Remove the anti-virus, it's running a root level process all the time that's taking your CPU and it's not necessary as there are no Mac viruses, Apple has the trojan angle covered already.
Always on anti-virus on a Mac is always a source of problems, also is MacKeeper, uninstall that here if you have it.
http://applehelpwriter.com/2011/09/21/how-to-uninstall-mackeeper-malware/
If you need to clean the Windows filth off PC files, then use the free, run as you need, ClamXav.
http://www.clamxav.com/
It seems your machine is used in a corporate enviroment, thus likely a rule that anti-virus must be used, you can avoid high CPU usuage by using the ClamXav instead. -
Hi,
Can any one tell me when the CPU usage will go high in oracle? What are the various reasons that affect CPU usage? what are the necessary steps we need to take in order to bring down?
I will be grateful to your answer
With Regards
BooCPU usage will increase in Oracle when what you are doing requires CPU resources.
To find of what those things are read the docs.
The steps one uses to decrease CPU utilization depend on what is causing it.
If you want to read the docs you will find them at http://tahiti.oracle.com
If you want someone else to read them for you hire a tutor.
