Recovering 2950 Ios

Dear Sir,

I have typed 'erase flash' command by mistake in my catalyst 2950 switch. After reboot, it stopped at "switch:" prompt.No IOS File Is Present In the FLASH, i Am having backup of ios & i tried to Restore using hyper ternimal, xmodem option,But it is giving the message "remote system is not responding". So what should i do for reinstalling the IOS.

Please help me as early as possible.

With Regards

Sumit Patil.



Re: Recovering 2950 Ios

Here is a guide on recovering the switch. If you have a helper image still loaded you should be able to tftp it after you load the helper image, otherwise, there is a step by step guide to using xmodem and also increasing the console speed to speed up the transfer.

Re: Recovering 2950 Ios

I don't have a 2950 to try but if you are in rommon and have the tftpdnld command available, try this:

rommon 1>IP_ADDRESS= Indicates the IP address for this unit

rommon 2>IP_SUBNET_MASK= Indicates the subnet mask for this unit

rommon 3>DEFAULT_GATEWAY= Indicates the default gateway for this unit

rommon 4>TFTP_SERVER= Indicates the IP address of the TFTP server

rommon 5>TFTP_FILE= c2600-js-l_121-3.bin Indicates the filename to fetch from the TFTP server

rommon 6>tftpdnld

Other questions: is your new ios bigger then your available flash? What is in flash?

I have a 2950 somewhere, just have to go dig it up, will respond again with more details once I locate a switch to test with.
