View 5 Replies View RelatedTrying to copy the system image file from the sup-bootflash to a new 64MB ATA flash card. Yes the software can support the 64MB card.
The ATA flash card was formated successfully, however I cannot copy the system image to it so that it can boot after a power loss.
The command I tried was: console(enabled) copy sup-bootflash: slot0:
The source filename was typed in as shown in the Show Verison command.The result was: Error opening slot0: no such device.I suspect that I am missing something obvious as I am new to Cisco Switches.
I had an old Cisco Catalyst 2948G switch that I have not used in about 7 years down in my basement. I powered it on and went through the process of clearing out the configurations, and I got to a point where one of the commands to clear out the config asked me to install jumpers for "ROM" and "ERASE". There is a third jumper labeled "NO BOOT". They are numbered J6, J7, & J8 respectivelyI found the jumpers inside and put the jumpers on them and ran the command expecting it to remove any old configurations I had on the switch and bring it back to factory state, but I was wrong.

There are green LEDs lit next to the jumpers inside, but that is all. I am not able to get any response from it on the console at all anymore.The LEDs that are lit green inside are labeled "CR5" and CR6".

View 5 Replies View RelatedI have a couple of 3560 switches running c3560-advipservicesk9-mz.122-44 and they are randomly experiencing the following:
- The switch locks up with no preceding error message in the log (I am forwarding syslog to Splunk).
- Upon reboot, the switch goes through the normal startup sequence with no error messages, then for some reason reloads the flash and starts all over again. (refer to doc)
This could happen after days or weeks. Sometimes they will go through two of these reloads on boot and be fine for awhile, and other times they will be stuck in the loop infinitely. I am using this same image with all of our 3560s, but am only having this issue with two of them.
i have a Cisco 6513 it is used one, i have tryed to boot it but it did not work, it alwayes go to rommon mode and i am not able to know what is the issue,

I have a 512MB USB Flash device and was able to boot the IOS on the C2960 from it.After that i tried to Copy the IOS file from the USB to the system flash, but it could not find the USB Device.At plugging in the device the systems tells me: "Transfer type 2 not supported" I configured the USB device in NTFS and FAT both are able to boot with the ROMMON, but the normal system does not accept them and i know i can do the copy over a TFTP from my laptop, but it is strange that rommon accepts the usb device and the system does not?

It doesnt let me use the enable command to get into it. I would like to start the config from scratch. Its a 3500xl switch, 24 ports. I dont know what to do with it.

View 6 Replies View RelatedI recently tried to manually format the flash on a model WS-2960S-48TS-L switch running IOS version 15.0(2)SE. While executing the operation I got the following error - mifs[8]: Failed to create superblock %Error formatting flash (I/O error).As a result the flash is no longer accessible by the switch. I spoke with Cisco and they indicated that a switch reload would remount the flash and make it accessable again but the .bin file would need to be reloaded using the xModem recovery procedure (what a pain).The next IOS version 15.0(2)SE1 will supposedly fix this bug but it has not been released yet. In the meantime if you are running 15.0(2)SE you may want to hold off performing a "format flash:" function on a 2960S.

I am testing on lab equipment (2 Catalyst 3550 and 1 Catalyst 3560) HSRP version 1 and 2.I successfully created a load balancing between the two Catalyst 3550 on a couple of vlans (11 and 12) on ver 1
now, just adding the command "standby xx version 2" my hosts on the 2 vlans are completely unable to ping the virtual IP def. gw on debugging i checked that msgs are exchangedthe two cat 3550 are seeing each other on HSRP (active / standby roles)the real ip addresses are pingable rebooted the swiches (just as a last resort try)deleted arp chache on hostsremoved the auth on hsrp all of this no effect.
i also tried to modify the priority on the cat 3560 (before he was on both vlans in standby) to make it the active one and with the same config it worked flawlessly.
My only idea is that there is a bug on CATs 3550 (IOS: c3550-ipservicesk9-mz.122-55.SE4.bin) [code]
I have a Cisco 2948G switch that I am trying to communicate to through this program. It has both an IP address and is hooked up through a cable. I can get Cisco Network Assistant to come up and ask for it's Username and Password, and that it is where I am stuck! I have no clue as to what to put in there as a username and password? I do have a password setup on the switch to login in to it during terminal mode, but that is it.
View 1 Replies View RelatedI am trying to find the serial number on the CLI that matches the serial number sticker on the back of a WS-C2948G-GE-TX switch that runs CatOS. I am running code cat4000-k9.8-3-2-GLX.bin. I have 4 different switches and all the stickers have a serial that starts with JPE.. and both "show version" and "show sprom 1" and "show sprom 2" gives me a completely different serial number that starts wtih JAE... All of these serial numbers I get from the CLI match with each other. The command "show sprom chassis" says "Feature not supported."
Is it possible to find the serial number that matches the sticker from the CLI on a 2948G? Why does Cisco make this so confusing?
I have a 2621 router, because I want an image of about 21M, I upgraded as follows:
IOS = 32M
RAM = 64M
ROM VERSION = 12.2
However, when I power up my router, it goes into a boot loop, and I see the following messages:
NOT ENOUGH MEMORY IN THE SYSTEM TO RUN THIS IMAGE
***SYSTEM RECEIVED A SOFTWARE FORCED CRASH***
how to overcome this error, and successfully upgrade, so I could load my new image?
We are setting up one of these for the first time. It is in a constant rebooting process.
