Re: which IOS ?

If you want to download the same IOS, do a dir flash: command from rommon and then you can find out the version number and feature set. For ex:

If the file name starts with,

c2600-is-mz --> The i stands for IP feature set and the S indicates its IP Plus.

After the mz, you should start seeing the version number.

"124-5a.bin" -- Indicates 12.4.5a IOS version.

Use this link to download. You will need CCO login and password.

Hello,

For general IOS features and requirements for your hardware you can use the Cisco Feature Navigator (requires CCO login)

Recovering the image you can use either tftpdnld method (quickest) or XMODEM.
