If you want to know whis ios is running do 'sh ver', you find a .bin extension, wich is the IOS
Hi
do you mean the router IOS or the running configuration ?
because the IOS is stored already in your router flash
here is a sample how to copy an IOS to tftp
Use "dir flash:" to view the files on the router
Make sure the TFTP server is started on the PC
copy flash tftp
Source filename []? c2950-i6q412-mz.121-11.EA1
Address or name of remote host []? 192.168.254.2
Destination filename [c2950-i6q412-mz.121-11.EA
best regards

u will need solarwinds TFTP server
make sure have it running. create TFTP common folder.
if this just lab, create vlan and give an ip add on switch.
int vlan 10
ip add 10.10.10.1 255.255.255.0
no shut
!
int fa0/1
sw acc vl 10
no shut
!
connect your pc to fa0/1 give it and ip of 10.10.10.2
run tftp server

1) Oh, i am sorry if i confuse you
2)When i execute "dir flash:"
- I saw "c1700-sy-mz.121-27b.bin"
- I have been able to copy this file to pc (through tftp server), and copy it back to the Router
3)My understanding:
This "c1700-sy-mz.121-27b.bin" is a FLASH (or a MEMORY); It is not IOS (as IOS is a program), right? Please confirm if you may
4)Thank you

ys it's the router IOS , in another words it's the firmware
you can be sure of that
by show version
you will see the same IOS as in the flash
c1700-sy-mz.121-27b.bin
send show version results

The IOS is stored in flash so im not sure i understand what you are asking. if you issue a
copy flash:<ios image name.bin> tftp this will copy the actual IOS that the router boots from.
to determine the name of the IOS file in flash issue "show dir flash:" you will see a list of files that are stored in flash. The ios is the .bin file.
