Debugging CRC Errors

Hi,
I am seeing some Header CRC errors and CRC Errors (398 and 561 per 5 seconds respectively),
I have a Syslog Server and I am getting data but I can't seem to debug the Dot11 traffic.
I am running this:
debug dot11 dot11radio 0 monitor crc
And I don't see any output via Syslog or Show Logging.
Running 1121's with 12.3(2)JA2 code.
Thanks,
Rob

Anyone have any thoughts?

Crc error between 2950 and 3620 router

I have connected the 2950 to the 3620, and the running-config of 2950 below:

And the 3620 router just set the interface ethernet0/3:

I have connected the f0/1 of switch to the eth0/3 of router. There are many crc errors between the switch and router, and try to change the duplex and speed rate, but it didn't take effect. I ensure the cable is good.
Thank you for your suggestion!

First, thank you for your notice of my problems.
Yes. When I ping from both directions, I'm seeing the CRC error only in the switch. And I have cleared the counters in both ends.
And I try to connect to another port of the router, It exists the same problem.
I'm seeing both of the input errors and CRC errors.

Input and CRC errors on ASA 5505 outside interface

All,
I see input and crc errors on my ASA 5505 eth0/0(outside) interface and packet drops. There is very slow connection though we have 20mb line. ISP also sees the issue on the Lan interface side. We have the speed and duplex configured same on both ISP and our end.
I am suspecting if this is Physical cable issue. Please suggest.

Hello Ravi,
This kind of issues CRCs/ Input Errors are tipically known as L1 issues so make sure you check the cable and if that does not make a difference change the port on each side to see if there is a difference.
Unfortunetly the ASA does not support the Time-Domain Reflectometer feature so we must do the test of L1 by ourselfs.
Can you clear the counters of the interface, test the changes provided and provide us some feedback?
Looking for some Networking Assistance?
Contact me directly at [email protected]
I will fix your problem ASAP.

Crc error in download of OBIEE 11g

I'm trying to get OBIEE 11g installed, but sadly one of the files i want to download keeps saying it is corrupt.
http://download.oracle.com/otn/nt/bi/111130/bi_windows_x86_111130_32_disk1_2of2.zip gives a crc-error when extracting it. I tried downloading it multiple times using different browsers/computers but no luck.
Do more people experience this or does anybody know a solution for this. A mirror to download the file from works fine for me too. Disk 1 file 1 of 2, and both files from disk 2 download and extract just fine.
thnx for helping.

Hi,
We have downloaded the files without any corruption,sometimes it happens due to internet connectivity.
Follow this link for download and installation http://onlineappsdba.com/index.php/2010/08/14/obiee-11g-111130-documentation-installation/
Hope helps you.Mark points.

Hi,
I had come up with this issue twice, once I download WL from a server from Asia, and had this issue. I just download once again from the server at US, and the issue was gone. The second time it was a weird anti virus configuration that tried to scan the file while the installation was taking place (I do not think this last one applies here.)

CRC Error on installing 10.2.0.1 on Linux

I've downloaded the 10.2.0.1 full Grid version for Linux and tried to install it
on Oracle's Enterprise Linux....
I keep getting a CRC error on disk 2....has anyone else seen this ?
Thanks
Bernard

Well if you've tried it more than once, then there is no point retrying it.
I've seen this happen in the past and redownloading it worked...but may be it's a bad copy online.
Let' see if someone else has seen this error...

How do HDD CRC errors manifest?

I have a KT4V motherboard and I wanna know how do HDD CRC errors manifest? I have problems with my computer locking up and I wanna know if this is due to a CRC error or I must look elsewhere for the solution.
I have BIOS version 1.7.

For what i know, the Kt4V seemed to be plagued with CRC errors.. If i remember right, BIOS V1.7 is suppose be correcting this problem.. This sorts of errors also might be caused by defective memory and in some very rare incedents with bend IDE cables.. What kind of memory are u using.. Kingston value RAM works the best with this board..

KT4V crc errors

hi there!
i have crc errors in my system,i read that a bios update will fix the problem
my system usually reboots when i ripping a dvd or moving files or i watch a dvd movie!
suddenly the screen becomes blue and the system rebooting...
i would like to ask if this is problem of the mainboard an if i can fix it with bios update
thank you!

I have no idea if this will work or is even related, but try this. First, you must be using Windows Xp, I do not know how to do this it you are not using it, but if you are, go to the my computer icon and right click it on the desktop, then go to the Advanced tab and under Startup And Recovery, hit Settings. Under System Failure, uncheck the Automatically Restart option. Hope that helps and read the "What's this?" help for the setting.

Did it complete or abort at that error?
It appears to be just a font file; it the installation completed, you might be able to
ignore this. If more CRC errors occur, the download might be corrupted.

Debug IP error help

Gurus,
Using Ciscoview to monitor our 3750 switch, I noticed high IP error counts. After connecting to the box and issuing the "debug ip error" command the following output was displayed:
"datagramsize=92, IP 27444: s=192.168.1.100(Vlan1), d=192.168.1.255, totlen 78, fragment 0, fo 0, dispose udp.noport"
The destination IP is the broadcast address of our subnet; Cisco documentation says that "the router received a UDP packet when no application was listening to the UDP port."
I'm trying to figure out why so much udp traffic is destined towards the broadcast address, and what is causing the IP errors.
Thanks for your help!
Kevin

UDP broadcasts are a normal solution to initiate connections between clients and servers. This should not nescessarily be an error but it could be a misbehaving application or something like a virus trying to spread.
Your search should focus on the source of the datagrams:s=192.168.1.100(Vlan1) If you are getting these packets from many different hosts, try to figure out which apps they have in common.
In that way, you should be able to find out wether it is caused by an application or a virus.

Leo

Crc error on oracle 9i for NT

after downloading disk1, file sizes do not match posted size and on extraction by WINZIP I get a crc error. Is this a download problem or a strange unzip problem or a glitch in the way the files were zipped?

the same problem I have encounter while downloading personal oracle 9i for windows98.

Why I get CRC error when copying outlook.ost file?

My workstation is using NTFS, Outlook 2007 with Exchange 2007 server.
My outlook.ost file is 1.7GB.
As my Outlook runs into problem, I tried to copy the outlook.ost file to another location for repair, but I keep getting CRC errors and the file was not copied.
I also tried to use winrar to compress it and it runs into the same CRC error.
Q#1. What causes this CRC error? hard disk error or software?
Q#2. How to repair such CRC error?
Thanks.

Hi Peter,
The cyclic redundancy check, or “CRC” error, indicates a bad spot/corruptions within the file that you are trying to copy and in lot of cases with your hard disk.
To make sure if the problem is with the .ost file or your hard disk, you can fire up a Command Prompt window, and then copy the file to NUL:
C:>CD (path of your .ost file)
C:(path of your .ost file)>copy name.ost NUL
If this succeeds, the problem is with your .ost file. If this fails, it should be a hardware based disk issues.
If it's an issue with your .ost file, I'd suggest to run
scanpst.exe tool to repair your data file, then check if this fixed it.
When the issue is hardware based, you probably need to find Disk Errors in the System log of your Event Viewer. You can access the Event Viewer by going to:
Control Panel-> Administrative Tools-> Event Viewer
By the way, .ost file is actually a local copy of your mail items on the server. For a corrupted .ost file, you actually don't need to "copy the outlook.ost file to another location for repair". You can simply rename it to .ost.old
or delete it, and then re-launch Outlook to let it generate a new .ost file from server.

Ethan Hua
