I'm having some problems when upgrading the IOS of my Catalyst 3750 switch through a tftp server. I've been surfing the net and found that there seems to be a problem when the image file is larger than 16M but this is not my case.I erased the flash to be sure that there was enough memory space to upload the image but didnt work.I also tried with archive download-sw /overwrite command and using a ftp server but the problem is the always the same: [code]To make sure it was not a problem of my computer or tftp server, I tried with a different computer and with a different tftp server but the same happen. I also tried with a 3750V2 and still the same. Even when trying to backup the current IOS to my computer, I got "error writing".
Then, I have tried to do the same with a different model of switch, a WS-C3560-48PS and it works perfect.I still need to try using Xmodem but Xmodem takes ages to finalize the process.

I am trying to create a backup of my 2620 router so I can use for GNS3.
I have only configured the IP address on my FastEthernet port. Having many issues with no connection to my pc, finally I found that you must enable the interface 'no shutdown'. Now I have a valid connection
I have made no other configurations on this router, everything else is default.
I can successfully PING from both ends
**PROBLEM: My problem is that when trying to 'copy flash' to my TFTP server, the response is**
".....
%Error opening tftp://192.168.1.3/c2600-advsecurityk9-mz.124-1a.bin (Timed out)
Router"
Is there another setting I should enable? Remember I have made no other configurations bar the ones above.

I recently posted this same issue the other day, using TFTPd32. Now i am pretty close to fixing it. I do have a different setup; my pc ethernet port is broken so I am using an ethernet/usb adapter. I am attempting to backup my IOS from a 3550 switch to my PC.
This is the error I am getting. Code...

I have a cisco 3750 swicth which i want to load a new ios to but unfortunately there's no enough space on the flash. This means that i need to backup the cureent (old) ios to my tftp server but the command keeps failing. It always gives 'No such file or directory' error .The free space on the flash is 8mb and my new ios is about 11mb.I also went inside the directory where the old is and inputed the same copy command but to no avail.Below are some of the command failure on the swicth:

we have two core swiches 6506 and around 55 cat 3550 switches. currently we are on the process of replacing the cat 3550 switches to 3750 switches.We need 10/1000/1000 speed, ip base image with upgrade options. Our up links from cat 3550s(sfps) are single mode and dual mode fiber mode with 1 gbps ports on core switch.
At present we are not upgrading to 10 gb modules on core. Spread over 15 floors each floor needs 2 up links(single mode , and dual mode). since cat 3750 sfps are smaller in size existing gibics cannot be used. Looking for the best option of cat 3750 switches with 1 gb up links which can be upgraded to 10 gb later when we replace the modle on core. Requirements:
1- Cat 3750 switches 55 in no with sfps for 1 gb up link (dual mode fiber and single mode fiber)
2- stacking option
3- 10/100/1000 speed
4- ip base image upgradable to ip service image
5- ipv6 compatibaility. Network is spread over 15 floors so from each floor we need two sfp up links 1 gbps using dual mode and single mode
-6-Should be upgradable to 10 gb in future when we upgrade the core modules
Or is it better to go for 10 gb module in core as well as edge switches ? if so what should be the modules?

I just need a little refreshing on upgrading a stack of 3750's. This stack only has 2 switches: [code]
1.) If I remember correctly I simply tftp the IOS to the flash of each switch and then reload the master only?
2.) Can I safely assume these are the 2 flash locations:

is there a document that explains the compatibility of 3750 series that can be stacked together? for example can we stack 3750-x with 3750-v2 without the power sharing? Can we stack a L3 3750 with L2 3750 without upgrading the L2 switch IOS to ip services?

The company I work have finally decided to enter the 21st century and invest in a new telephone system (Interactive Intelligence) to replace the legacy system which has served us well for the past 10 years. The project has only just started and involves upgrading sections of CAT3 cabling to CAT6, replacing Cisco 3550 switches in one area of the building with Cisco 4507 switches and upgrading our Core switches with Cisco Nexus 7010's. The area that concerns me most is enabling the network for qos as I have very little experience with it. At the moment Im trying to read as much documentation as I can on QOS to bring myself up to speed.
The access layer switches will consist of a mixture of Cisco 3750 & 4507 switches connected to Cisco Nexus 7010 switches which will form a collapsed aggregation & core layer.
Basically, how I should approach this daunting task of making sure the network will support VOIP.

I am trying to convert two Aironet 1141n access points to autonomous stand-alone units. I have connected the console cable and I can see the unit giving information in the console window, but I cannot type any commands. When I try to get the unit to upload the c1140-k9w7-tar.default file by holding the mode button in for 20-30 seconds, it shows it is examining the file, and then states that the connection to the tftp server has timed out. My windows firewall is off, the interface is configured as 10.0.0.2 255.255.255.0 and the tftp server is showing that.

Have a small stack of two 3750 routers. Get the following error message every few secounds:
%STACKMGR-4-STACK_LINK_CHANGE: Stack Port 1 Switch 1 has changed to state DOWN
%STACKMGR-4-STACK_LINK_CHANGE: Stack Port 1 Switch 1 has changed to state UP
Now I replaced the stacking cables but no joy. It was ok for an hr or so but then the error messages popped up again. Also random links on this stack back to access layer user switches have been going up and down randomly. So I have decided to take the next step and upgrade the IOS.
Although when I try and copy a new IOS I get the following error:
%Error writing flash:/c3750-ipservicesk9-mz.122-55.SE6.bin (No space left on device)
Seems this image is 130MB while the image that is currently on it is 74MB and free space is 54MB. How do I get the image onto the router? If I delete the current image from flash will that cause the router to stop functioning?
Also I noticed there seems to be more than one flash directory. See below:
copy tftp: ?
flash1: Copy to flash1: file system
flash2: Copy to flash2: file system
flash: Copy to flash: file system
null: Copy to null: file system
nvram: Copy to nvram: file system
running-config Update (merge with) current system configuration
startup-config Copy to startup configuration
system: Copy to system: file system
vb: Copy to vb: file system
The current router image seems to be in flash1 and flash 2 also. Could I delete the image from flash1. Upload it there and then boot the router from flash1?

We have a stack setup with 2 C3750x-12s and 5 C3750x-48p switches. We have two of these stacks. One is working and responding with snmp just fine. Our second one is showing the errors in the logThe only difference i see between the two stacks right now are the sw versions.

We have a number of 3750 stacks used as access layer switches connecting Siemens VOIP phones and then a PC that connects to the phone.
For example if I plug PC A to the phone that connects to port 13 I pick up an IP addressand all works as predicted now if I plug in PC A to any other VOIP phone that connect to another port on the same switch it goes in error disable state ITs like the switch is holding my PC mac address and locks it down with the port which in my case is Gi2/0/13.
interface GigabitEthernet2/0/13
switchport access vlan 726
switchport mode access

I recently upgraded my network to have two 3750x core, one interface on the Cisco is connecting to a Net gear switch via a fiber converter. I am keep getting the vlan flapping error message in my log as below.

After my research i think this is a looping issue but I'm unsure how to address it.

We have ip arp inspection and dhcp snooping enable in couple of 3750 and 3560 switches. Everything works fine, excepted few case that DAI packet rate trigger and errdisable the port. Later on we found out that most of computer that trigger DAI is Windows 7 and especially when they are in sleep mode. Not sure if anyone experiencing it with Windows 7. Also we have it rate limit at 64.

i want to boot my Router's IOS from TFTP server but when I use the command: boot system tftp c2801-adventerprisek9_ivs-mz.124-24.T7.bin 172.16.10. 200; after that I write-mem, it shows the log:
-Router#wr
-Building configuration...
-ROMMON: out of room in table, cannot set "BOOT"
And when I reload the router, it cannot boot IOS from TFTP Server, sure my TFTP work well and 2801 can ping to TFTP.

I have a really stupid problem with my RV042. The main logon password has expired but it will not let me change it at all. Basically I try to login but get the error 'The old password has expired. Please change the password'. But with no prompt at all for a new password and just a return to the login page. Tried various different browsers, tried the old default password but nothing will work. There seems to be no way of changing it and I cannot login.Am I missing something glaringly obvious? I really don't want to reset it to default as I have numerous VPN tunnels configured and various other settings.

I have been looking at grading the IOS version on our 6509-E however there is not enough space on disk:0 to upgrade to the version I need to install. The question I would like to ask is - is it possible to boot the IOS from a TFTP server? If this is possible what configuration do I need on the 6509 to enable this. How does the 6509 know about the TFTP server as an IOS is not installed and therefore it will not have a network configuration

I'm trying to upgrade my 2950G-24-EI via tftp but it looks like the sw can't transfer any of the files completely or with errors. I downloaded the BIN+TAR files from Cisco (and from another site) matching my Catalyst and opened an TFTP server on my PC. The files are :
c2950-i6k2l2q4-mz.121-22.EA14.bin

On my 2960, 3550, and 2801 equipment which all have IOS 12.2 or 12.3 I am able to obtain things like "show tech" and save it on a tftp server in this manner: ch3550#show tech | redirect tftp://192.168.18.18/techsupport.txt,This is because the | pipe has a bunch of options it refers to as output modifiers.HOWEVER, on my 3750, I am not able to do this. The list of output modifiers has changed, and "redirect" is not available. Consider the following: The 3750 unit I am working with is WS-C3750G-12S with IOS version 12.2(25)SEB2,Now, I know I can capture the show tech output via other means such as in the buffer of Putty.exe.

In the process of upgrading the image for all of our floor switches..In total there are 35 WS-3560G-PS switches.
So far I have been upgrading them all to image c3560-ipbasek9-mz.150-2.SE2.bin and that has gone well.
But this eve 2 of the switches are extremely slow on the TFTP transfer. Duplexing and links are good back to core.
But when I do a sh ver to compare one switch that is good and one that isnt I noticed this
TFTP Transfer is good on this one - cisco WS-C3560G-48PS (PowerPC405) processor (revision F0) with 122880K/8184K bytes of memory.
