Cisco Switching/Routing :: 3750x Doesn't Boot After Upgrade To Version15
Apr 22, 2013
Due to a problem with POE+ i have tried to upgrade the IOS to Version15.0.2SE2, from 12.2.58. unfortunatly the Switch doesn't boot up anymore. It starts to decompress and install the IOS 2 Times, after the Second try it displays "unable to boot" and the switch goes in Bootloader-mode. When i look at the version i See that bootloader is still the old version 12.2.58. It seems that the bootloader doesn't geht upgraded and that's why the Switch can't Boot the new Image.
I wanted to upgrade our three WLC 4402 from software version 5.0.148 to 18.104.22.168. The upgrade on the first controller was working. Unfortunately he lost all the local management users and it's MAC filters, but restoring this was not the problem. After upgrading the second controller.... the device does not boot anymore! The alarm led is RED and I don't know what to do. The only way to get connected to the controller is via the console port. There I can see a "parse error" but I don't know if that is the problem. Please look at the "log" attached. I'm not sure if the red alarm led was there before upgrading the controller software because the device is located to another place. I'm really concerned about upgrading the third controller because it's the most important wlc.
I am planning to upgrade BootLoader image of 7206VXR router due to booting issue. The router is not booting .But if I go to rommon and give boot it will boot.So I am upgarding my Boot Loader image. Now the Bootloader image and IOS image are exactly same.Can I upgarde the Bootloader image to latest version without upgarding IOS?
I've 3750X switch that isn't loading email. then I went to rommon mode and accidently for "format flash". after that I loaded 15.0 SE2 s/w on it using tftp server but it doesn't boot up with that image. flash had only .bin file after I loaded it from tftp server.
since it wasn't booting up, I did format flash again and thought to load image again from tftp server but now, it doesn't load image from tftp server.
Switch 2 has an interface configured in RSU Standby.Switch 3 has an interface configured in RSU active. The upgrading sequence is : Switch 2, Switch 1, Switch3.The aim of the test is to prove that there is no loss of IP connectivity throught the RSU process.During the RSU process, there are ping between all the computers.
IOS starting version : 15.0-1.SE3 IOS upgrading version (with OVERWRITE) : 15.0-1.SE3 (same version)
1rst step : Switch 2 reboot and come back master but isolated from original stack (switch 1 and 3)
2nd step : Switch 1 reboot, and come back with switch 2 into the upgrading stack.
Issue : at this step :
- Switch 1 put its interface (IP 192.168.5.254) up :
- Switch 3 has not reboot and still has its interface (IP 192.168.5.254) up
=> we have some OSPF adjencies and mac flapping issues : switch 1 and 3 are trying to mount there OSPF adjencies on the same IP. We loss our IP connectivity since step 3 is not over.
3rd step : Switch 3 reboot and come back up in the upgrading stack. The IP connectivity is back, and the RSU process is done.Is that a normal behaviour ?How can we avoid to loose IP connectivity during RSU process ?
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 ?
I have upgraded my Catalyst 3750X-switches to software-version 15.0(2)SE2, but I cannot upgrade the 10G servicemodule to the same version. I use the archive download-sw command to load the c3kx-sm10g-tar.150-2.SE2.tar. The file is loaded to the switch, but when the process starts to transfer the file to the module it fails with the following messages:
Error 2: Unable to transfer image to FRU Modul on switch 1Error: Failed to update FRU Module image
The modules is now running with in-compatible versions as shown below:
Switch# H/W Status (CPU/FPGA) CPU Link Version ----------------------------------------------------------------- 1 OK 77C/71C ver-mismatch 03.00.41 2 OK 73C/73C ver-mismatch 03.00.41
I have two 3750x in a stack running c3750e-universalk9-mz.122-55.SE3.bin with License Level: ipservices?I am planning to upgrade to c3750e-universalk9-mz.122-58.SE2.bin will this keep my ipservices licence or revert back to IPbase
I have a remote customer who is having issues with their 3825 router - since I can't be on site troubleshooting is difficult but so far all that seems to happen when the device is powered on is the "SYS PWR" light goes solid green, and no other lights come on. Fans seem to be operating normally. Console access doesn't appear to be working.
I unpacked a new 3560x and went to put our standard code version on it c3560e-ipbasek9-mz.122-53.SE2. Everything seemed to upgraded fine but it won't boot to a console prompt. It seems like it loads the IOS image fine but can't get passed the Front-end Microcode IMG MGR: Programming device 0. [code]
My management has tasked me to give them a high level overview of the different switching we can choose for our new building.
This is what I know so far.4 Closets, each closet has 450 ports,One MDF room that is will contain one UCS Chassis and a Nimble iSCSI SAN.
I am working on the spreadsheet and it looks like this (Not totally filled):

i cant find any difference in these two devices when i am trying to compare throughput.I need upgrade our new POP and there will be around 4900 MAC adresses in VLAN 150 and 130 MAC adresses in vlan 200.Uplink is 1 gig routed internet connection and there is 14 downlinks to separate villages.i found a few differences for eg stack interface on 3750x but i dont need it.
I have a stack of 2 x 3750X switches these are running 12.2(55)SE5. I needed to add some static IP routes and found that the ‘ip routing’ command is not supported. I came across a document that stated “On switches running the LAN base feature, static routing on VLANs is supported only with Cisco IOS Release 12.2(58)SE and later.” So I have upgraded to 12.2(58)SE2, but ‘ip routing’ is still not a valid command.
The release notes state:“On the Cisco Catalyst 3560-X and 3750-X Series, it adds support for 16 static IPv4 routes in the LAN Base image.”
I have read other posts that talk about running the ‘sdm prefer routing’ command which I have done, but I am still unable to add any routes or run the ‘ip routing’ command.
I tried to upgrade IOS from SXI2a to SXI9 in cat 6506 VSS. But the problem is that switch always boot with old IOS. I put the new IOS in sup-bootdisk and slave sup-bootdisk, bootvar is ok with new IOS: [code] Show bootvar is ok but switch always boot with old IOS SXI2a, some bug in IOS sxi2a???, I will try to delete de old IOS from sup bootdisk and try with the new one only.
my Catalyst 3750 switch. Following a power cut the switch no longer boots up. The SYST light flashed green but no POST checks are made. I cannot see any boot messages from the console port either. The switch was on a UPS but some thing may have damaged the switch.
What would happen if I installed a 32MB (MEM870-32F=) flash upgrade card in to a Cisco 871 router that already had 28MB flash on-board already? Would the router boot seeing 52MB (the max this router can have) or would it fail completely since the combined total would be over 52MB?
I know you can get a 24MB upgrade card but they are quite expensive.
Last night we had some pretty bad lightning and thunder and our Linksys WAG160N appears to have had a bit of a fright.As I was going round unplugging items in case of a hit (this was after a flash or two, relatively nearby), all the lights on the router were off except for the ethernet light (plugged into a Linksys homeplug adaptor). Now the router doesn't appear to boot. When powered on, the power light doesn't flash or anything to indicate booting up, all you get is the ethernet light (if connected) after a few seconds, but no activity. I'm presuming something has been fried or corrupted? I'm not sure if we did have a power spike either through the mains or phone line as all other equipment seems to be fine, but I'm wondering the the homeplug connection might of had something to do with it after reading a few posts from others on the subject.I've held in the reset button while starting and it doesn't appear to have done anything. I will try the 30/30/30 reset tonight.
