Catalyst 2950 - Problem updating IOS

I am trying to upgrade from version 12.1 (14) EA1a to version 12.1 (22) EA5 on a Catalyst 2950. When I look at the flash directory, I see the following:
Directory of flash:/
2 -rwx 269 Jan 01 1970 00:01:27 env_vars
3 -rwx 1247 Mar 09 1993 06:09:06 config.text
4 -rwx 5 Mar 09 1993 06:09:06 private-config.text
7 -rwx 110 Mar 01 1993 00:01:39 info
8 -rwx 2958970 Mar 01 1993 00:03:19 c2950-i6q4l2-mz.121-14.EA1a.bin
9 drwx 2304 Mar 01 1993 00:04:30 html
84 -rwx 110 Mar 01 1993 00:04:41 info.ver
7741440 bytes total (2480640 bytes free)
When I try to delete the old file (c2950-i6q4l2-mz.121-14.EA1a.bin), I receive a message that the No such file or directory exists. There is no typo when I entered the filename. Also, there seems to be a discrepancy in what free bytes are being shown as available. The system shows 2480640 free bytes, but by my calculations, there should be 4778425 bytes available. Are they files that are hidden and why can I not delete the other file? Thanks.

Hi,
Are you able to dlete any other file except this from the flash. This could be a problem in accessing the flash properly. I would suggest try formatting the flash:, this will make the flash sectors empty and will be as a new scratched one. This should help in uploading the new IOS.
***** Please make sure that the switch doesnot reboot at while while you format the switch and upgrade the IOS as the switch will fall in rommon with any image.

Hi,
So your home button doesn't work so that's a no on the hard reboot. I had that same problem and what i did is hold the lock button until it shut off then turned it back on. You could do that until it works, which is what i used to do.

There is a support article about error code 3259.

Either of these articles should help.
Also antivirus software enabled can cause problems with the downloads in iTunes.

Problem updating ios 4.2 to 4.3

The message says "there is a problem downloading the software. The network connection timed out. Make sure your network setting are correct and your network connection is active or try again later". It happens to my iPhone 4 and iPad. I am using itunes 10.2 on my windows XP laptop. What seems to be the problem?

Download the file separately from here (it's the Apple download site):
http://appldnld.apple.com/iPhone4/041-0551.20110325.Aw2Dr/iPhone3,14.3.1_8G4Restore.ipsw
Then press the Option (alt) key (shift key if you're Windows) while clicking the update button, and install from your hard disk

Other people have found that temporarily disabling their antivirus and firewall has worked.

Catalyst 2950 problem

cisco Switch 2950 showing problem while connecting with other device(Packetwave bridge 100) or switch(Dlink)
Output of uplink port is:
%SPANTREE-7-RECV_1Q_NON_TRUNK: Received 802.1Q BPDU on non trunk FastEthernet0/22 VLAN1.
00:20:54: %SPANTREE-7-BLOCK_PORT_TYPE: Blocking FastEthernet0/22 on VLAN0001. Inconsistent port type

The message means that a Spanning tree BPDU was received with a dot1q tag on a port that is not configured as a trunk.
This means that either the port is not configured as a trunk and should be, or that the connecting device is configured as a trunk and should not be.
The second syslog message indicates that the port is being blocked due to the inconsistency as described above.

Problem updating iOS 5

Hello
Everytime I finish downloading the 'iPod Software Update' for my iPod Touch 4G, an error message shows up saying "There was a problem downloading the software for the ipod. The network connection has timed out." although I am still connected to the internet and I have an excellent internet connection.
That error message always shows up AFTER the download and I think that is not normal :/
I have tried downloading it 10 times, I restored my ipod to its factory settings and I uninstalled and re-installed iTunes to my laptop but the problem still occurs
I assume that the problem is iTunes or the software update itself, and not my internet connection,but I am not sure if I am right.
Do you know any solutions for it? Any suggestions?
Thanks in advance.

Thank you so much! It worked! I have updated it now and i'm restoring my iPod as a backup

Problem update ios 4.3.3. auf 4.3.5

ich habe bisher die firmware-updates problemlos über iTunes vorgenommen.
dieses mal hängt das update beim iphone-backup immer wieder.
am iphone steht "synchronisieren..." in ITunes bewegt sich der balken aber nicht weiter.
nach einiger zeit startet das iphone neu oder ich stöpsle es ab und iTunes muss ich mit dem taskmanager abschießen.
das iphone funkt auch mit 4.3.3 problemlos - bin nur etwas verunsichert.
das ganze läuft unter Windows 7 32 Bit
danke für eure antworten.

Is anyone else having problems updating iOS 6.1.3? It keeps telling me that I am not connected to the Internet. But, I am. Frustrating.

I cannot update 6.1.3

Restart or reboot your iPad and then see if you can update.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Hello,
what other switches do you have in your network ? If you have just the 2950 and the 3500, make sure that the 2950 is the root switch for all your VLANs, by configuring the global command:
spanning-tree vlan x priority 0
Also, check the log on the 2950 for the following message:
SCHAN ERROR INTR: SRC=6 DST=5 OPCODE=20 ERRCODE=5
If you see those, chances are that you have a faulty unit. Here is the relevant bug info:
CSCdv83336 Bug Details
Under certain level of traffic load, the (2950) switch will start logging the following messages on the console:
SCHAN ERROR INTR: SRC=6 DST=5 OPCODE=20 ERRCODE=5
and after a few seconds, the switch will stop passing any traffic. In some cases, the switch seemed still forwarding broadcast and multicast traffic, which will cause STP problem if the switch has redundant link and is not supposed to be the root for the VLAN, as both port will go forwarding.
The same error message has been identified in CSCdu87836.
An assessment of the impact
Unit stops passing any traffic.
WORKAROUND
Several units were returned by CISCO. The units were re-screened to the latest test program, and failed the SDRAM memory test.
Customer should RMA unit back to Cisco

Follow Troubleshooting security software. Often, uninstalling third-party security software will resolve these errors.
There may be third-party software that modifies your default packet size in Windows by inserting a TcpWindowSize entry into your registry. Your default packet size being set incorrectly can cause these errors. 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).
Verify that access to ports 80 and 443 are allowed on your network.
Verify that communication to albert.apple.com or photos.apple.com is not blocked by a firewall, or other Internet security setting.
Discard the .ipsw file, open iTunes and attempt to download the update again. See the steps underAdvanced Steps > Rename, move, or delete the iOS software file (.ipsw) below for file locations.

Please do not post the entire messages log as it takes up unnecessarily a lot of space. It seems that there is a corrupt/nonfunctional file called

Go to your hard drive, enter library, go into users, and go into launch agents and delete the thing above. Empty the trash and restart.

Not very helpful but I have the same issue. Plugging in and doing the update via. iTunes will probably work but I find that whole experience annoying (downloading apps not on the Mac, etc..)
