Dear guys,
i am trying to install a different IOS to my 3550 switch as a practice, but before the installation, i would like to try to back up the current IOS to my TFTP server as a back up, since i am a very beginner of using Cisco switch, i got the following problem that need help.
1. i failed "copy flash tftp: or "archive upload-sw tftp" to back up the current running IOS to my TFTP server. below is the show flash result.
Switch#sh flash
Directory of flash:/
7 drwx 192 Mar 01 1993 00:03:08 c3550-i9q3l2-mz.121-11.EA1
15998976 bytes total (11623936 bytes free)
Switch#
2. as above, c3550-i9q3l2-mz.121-11.EA1 is currently the IOS running in my 3550, but why is
the size so small (only 192 ??) comparing to the IOS that i am going to install to it ?
is this really a IOS or is it the bootup ? since the IOS i am going to install is around 6M in size.
3. what should i do in order that i could copy the current IOS to my TFTP Server as backup?
4. what command should i type in order to download the new IOS to my 3550 swtich from my TFTP server ? is it as simple as "copy tftp flash" and "archive download-sw flash" ??
Thanks Guys !!
