Copy IOS on 3550


How do i copy a IOS from Cisco 3550 to a tftp server on my PC

Question is -- Do i use the port on the switch connected to the tftp server as routed port(no switchport command) or as a switchport

If switchport then should it belong to vlan 1 with the same subnet ip address of tftp server.

I tried copying IOS from Switch but it gave me error message

"Directory cannot be found"


Re: Copy IOS on 3550

Can you currently ping your tftp server from the switch when the tftp server is connected?

If so - when you input "show flash" do you see a file name with a ".bin" extension?

If so - then you need to input "copy flash tftp" it will then prompt you for a server IP then a file name


Re: Copy IOS on 3550

a routed port is possible but not required.

You just put a port in the same vlan as the management vlan.


int vlan10

ip address

no shut

int G0/1

switchport access vlan 10

=> give your pc an address of the same range as vlan 10. For example

then you should be able to ping your switch

You've also to check if the IOS is installed in the root or in a directory via "show flash" If the filesize is small and you see a d in front "drw-", you've to give the path to the image when it asks for filename in the procedure of Andrew.
