Cisco WAN :: 3750 IOS Upgrade Failure
Feb 20, 2011
I'm trying to upgrade a 3750-24TS from c3750-ipservices-mz.122-25.SEE2 to a more recent image. On the first pass, I got
Error: There is insufficient space in flash: to install the requiredError: image. Clean up some old images, and try again.
So I used the delete /recursive flash:image-dir-name to clean out the old files, but I'm still getting the same message after doing this. What's the problem? Now I have a switch with no IOS and need to at least get something on there.

I've been working with a client's integrated 3750 WLC running 4.0.179.11. I want to upgrade the code because it is old plus I am having DHCP trouble. I have a couple of questions:
1. Is it OK to upgrade to SWLC3750K9-5-2-193-0.aes ? or do I need to go through 4.2 first ?
2. Will that code upgrade the bootloader at the same time?
3. How can I make sure there is enough flash space on the WLC?
4. Are there any special considerations to plan/prepare for?
The DHCP issue is failure of associated clients to get an IP address with this message found in WLC debugging:

I have a Cisco 1200 Series (AIR-AP1231G-A-K9) access point, I have been upgrading these models to lightweight mode but are having issues with one in particular, this access point keeps "rebooting" itself, I am assuming that the upgrade failed, how can I get the access point upgraded?
When I start to access the AP by typing "enable" and enter the password it starts resetting again.
I have reset the AP by the mode button, power option but still not working.
At this point I would even accept a fix to get it back to working condition. Here is a capture.

Tried upgrading my firmware to 4.0.2.08-tm and now I cannot log in via the web interface. The router boots and gets out to the internet. It still allows incoming vpn connections. The login screen displays and will display an error message if I use incorrect credentials, but if I log in properly and am directed to the routers web config homepage at "192.168.1.1/default.htm", I get a 404 error message. Telnet does not work either (not sure if it's on, never used it before) 404 Not FoundThe requested server-side-includes filename, /usr/local/EasyAccess/www/htdocs/default.htm, does not seem to exist.As if the web pages after the login screen got removed or corrupted after the update.
SN is NKS10403247
I realize there is a newer version. Attempted the upgrade incrementally since I could not find documentation specifiying if that was required or not.

This weekend we have upgraded the ios on quite a few switches on a larger site, the site is a mix of 2960 and 3560 switches and the previouse ios versions were 12.2.44 on most switches but some had an older 12.2.25.On monday when we came into work we got a call that most of the ports on these switches were an amber color and most people could't use the network.After some investigation we discovered that we had a problem with dot1x so for a quick solution we just removed it from the switches and restarted all the ports with no dot1x enabled,[code]

We have a stack of a 3750E with a 3750X, when we turn off the master, a disconnection occurs for around one minute while only one request timeout is seen when the slave is turned off. Is this normal? Details: in other words, when the slave switch is elected as the new master all the port-channels and some physical ports become in 'down' state before reobtaining the up state again, this results in a one minute outage. The question is: is it normal to have a layer2 control traffic interruption when the master fails and re-election occurs and if yes, what is the normal downtime in seconds. the layer2 control information such as port-channels LACP protocol are not synchronised to all slave switches by the master?

IOS upgrade tried on the stack of 2XWS-C3750X-24T-S , Upgrade was tried to support WCCP on the platform. Current version is Cisco IOS Software, C3750E Software (C3750E-UNIVERSALK9-M), Version 12.2(58)SE1, Not able find any IP Plus ios in the site ? Only available are IP base and Universal K9 , Tried upgrading to c3750e-universalk9-tar.122-58.SE2.tar by using stack upgrade method as per document [URL]
Upgrade fails with error :
%Error opening flash:update/info (No such file or directory)
ERROR: Image is not a valid IOS image archive.
Why current ios is not supporting WCCP , I hope it is there in the featureset. ( tried "sdm prefer routing" but no success) Does c3750e-universalk9-tar.122-58.SE2.tar will give me wccp support ? What is the issue with my upgrade and how do I do a successfull upgrade ?

applied an iOS update to a stack via tftp. I used the archive Download-sw tftp:// method. I rebooted the stack after complete and it never came back up. I discovered the master switch upgraded but not the member. The member was sitting there with all amber lights on and frozen after the iOS load. The master wouldn't finish boot until I removed the member from the stack. I had a version mismatch and they would not communicate.

I have tried to upgrade the firmware to the latest greatest but keep getting the "Incorrect image file" error. I bought two of the V1 units and had no trouble with one of them but the other is frustrating me. I have reset it and even tried a tftp upgrade of the firmware but still get "Incorrect image file" even in tftp.

I was prompted by Cisco Connect to upgrade the router software. During this process it came back and said the update failed. At this time the network connection dropped. The power light is now flashing on the device.

The Catalyst 3750 switch reboots, and the " Reloading because of stack merge or communication failure" error message appears.
I saw this issue at "Cisco wiki" but the resolution in that page is just "Open a case with TAC". Because of the reasion is H/W Problem.
Is The resolution only one ? anything else? The 3750 does not use Stack.It is just stand alone. So i think it has other resolution as "disabling Stack" or another one. How about my opinion ? Is the Resolution only "Open a Case with TAC"

I just upgraded a stack of 4 3750s from 12.2(53)SE2 to 15.0(1)SE2. The stack took awhile to come back online (about 20 min). I wanted to make sure this isn't a compatibility issues with the Boot Loader which is (C3750X-HBOOT-M) Version 12.2(53r)SE2, RELEASE SOFTWARE (fc1).

We have 2x Cisco 3750 WS-C3750-48PS-S and 1x WS-C3750-48PS-E in stack mode. They all work well. Currently they have c3750- ipservicesk9-mz.122- 25.SEE2.bin on them which is deffered by Cisco. What would be a good alternate, stable version for my switches? Switches have 16MB flash and 128mb Ram.

I have a situation where I have a 3750-X stack bought with the 350w power supplies. A "show Inv" lists model as "WS-C3750X-48T-L". I now need to suport POE in that space. Is it possible to add in a 1100W power supply and have the switch support POE or is the chassis different and cannot support POE, no matter what PS is installed?

We are going to upgrade our IOS on our WS-C2960G-48TC-L. But before we do that i want to ask whats the best IOS release to choose. Why we want to upgrade is because our switch software now don't support ssh just telnet access
Switch details:
Model: WS-C2960G-48TC-L
SW Version: 12.2(25)SEE2
Image: C2960-LANBASE-M
I was thinking about upgrading the IOS to 12.2(44)SE6 are maybe i should upgrade it to a newer release?
One more thing we have a bunch of stacked 3750 switches, that also need to be upgraded.

I'm trying to use LMS to upgrade a stack of switches that have 1 or more 3750x's and other 3750's. In Software Distribution, if I choose Distrube to devices, basic, it finds the x switch, which is the master but says the others are not candidates. I don't see a place where I can tell it it is a mixes stack and choose multiple IOS's.

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?

I am trying to do ios upgrade on 5 stacked 3750 switches. All the switches have different model number, so i am wondering which image file i should download. As far as i understand all the stacked switches should have the same IOS, i may be wrong. The switches have the following model numbers and SW images;
Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
1 28 WS-C3750G-24PS 12.2(35)SE5 C3750-IPSERVICESK9-M
* 2 28 WS-C3750G-24PS 12.2(35)SE5 C3750-IPSERVICESK9-M
3 52 WS-C3750G-48PS 12.2(35)SE5 C3750-IPSERVICESK9-M
4 30 WS-C3750E-24PD 12.2(35)SE5 C3750E-UNIVERSAL-M
5 30 WS-C3750E-24PD 12.2(35)SE5 C3750E-UNIVERSAL-M
which image file i should use as they all have different model numbers and Cisco provides different image files for each model.

I recently added a 3750X-24P-L into a stack of 3750V2 switches. I did so by getting the temporary upgrade license from LAN Base to IP Services; I added the switch no problem. I now have the permanent license and I was wondering if I could install the permanent license without having to remove the switch from the stack. I tried a license install but that failed. The switch is not currently the master but I figured I might promote it and then try the install.

I have Cisco Catalyst Stack structure that consist of;
3750E-48TD-S (MASTER) (UNIVERSAL Image)
3750G-48TS-S (IPBASE Image)
3750G-48TS-S (IPBASE Image)
3750G-48TS-S (IPBASE Image)
I want to upgrade their IOSs to k9 images.
I can not dowload Universal Image file from Cisco website because of the expired service contract. I have IPBASE IOS files for all switches,
Can it be a problem to upgrade master switch IOS from Universal to IPBASE image?

I want to run rolling-stack upgrades on several stacks containing Catalyst 3750X-switches. I have done as follows: Configured the redundant uplinks as active and stand-by.Started to upgrade by using archive download-sw /rolling-stack-upgrade /overwrite /reload The upgrade starts as expected BUT switch number 2 in the stack is reloaded BEFORE switch 1 is finnished, the result is of course downtime for the stack. The documentation says something about the command "boot time", but what is this command doing? The default seems to be 7 minutes, it this parameter the time the upgrade-process waits before booting the next switch in the stack? I would expect that switch number 2 is reloaded when switch 1 is up again after reload, and not after an absolute number of minutes, is the rolling-stack-upgrade not working this way ?

I have read that the 3750-X supports upgrading with minimal traffic lost with RSU feature, on the configuration guide the scnario is with the end user connected to the 3750-X stack with LACP and the uplinks to the network running STP, one uplink is forwarding and the other is blocked. I have the same scenario but for the network uplink i also have LACP. When i tried to configured the RU stanby one of the uplink LACP the switch gives an error.
