Cannot FTP new IOS from PC to Switch

[jmalge]

Hi all. I'm pretty new to Cisco equipment and I'm working on a lab where I am trying to load a new IOS onto a 3750V2 switch. 

Here are the details.

Network. /24

Switch IP 192.168.1.1

PC IP 192.168.1.3

(Undefined error)

I'm not sure what I'm doing wrong so I'm looking for help.  I'm connected into FA1/0/1 which was showing up/up.  I would really appreciate any help I can get.

For the record, I've also tried FileZilla which doesn't seem to want to connect to the switch either.  So maybe there is something with the config that I'm doing wrong.

[graham smart]

just for the hell of it..

conf t

int fa1/0/1

no shutdown

switchport mode access

switchport access vlan 1

end

conf t

int vlan 1

no shutdown

end

Can tyhe PC ping the switch?

Can the switch ping the PC?

You may also need to supply the username and password on the FTP command line from the switch.

Note: Your filezilla wont be able to ftp to the switch, the switch is ftping to the pc..

ftp:	[[//[username[:password]@]location]/directory]/filename For example: ftp://network-config (prefix://filename) ftp://user1:secret@example.com/3600-configsecret@example.com/3600-config

Hello Jason,

you need an FTP server running on the PC and also in the switch configuration you need to specify the username and password to be used to authenticate with the FTP server

config t

ip ftp username

ip ftp password

this is because these parameters are not asked by the IOS prompt so you need to instruct the switch on what to use.

The FTP account has to exist on the FTP server and to have at least reading rights, the IOS image has to be present at the working directory of the FTP server.

Hope to help

Giuseppe

Hi guys. Thanks for the responses. 

I have verified all of this information and made the config changes accordingly.  I'm still getting the undefined error.  I have even tried FileZilla thinking maybe that I could connect that way, and no luck.  I put in the username and password that I set, and it gives an EConnRefused- Connection refused by the server".  I wonder if there is still a setting incorrect that I'm not thinking of.

Any other ideas?

[graham smart]

Seems that either you have a firewall enabled on your server or your username / password is incorrect.

On your server/pc  open up internet explorer..

Now type in the url bar:  ftp://username@localhost

Enter the pasword in the popup box.

Does it let you in? can you see the files?

if you can, then the server is running fine and it may be a firewall issue.

if you cant login then your server may not be running or your details are wrong..

Just to make like easy, It may be better to just use tftp..

Ie: http://tftpd32.jounin.net/tftpd32_download.html

Then just use copy tftp://yourip/filename.bin flash:

tftp is slower but no need to passwords etc..

Hi Jason,

Hop your doing good!!!

Cisco has removed FTP command from most of recent IOS ,as Its saying there is bug ,due to router gets crashed and reload

Better you can use TFTP

follow below procedure

conf t

itn vl 1

ip add x.x.x.x/24

no sh

int fa1/0

description to tftp server

switchport

switchport mode access

switchport access vlan 1

no sh

exit

#ping x.x.x.x (ip address of tftp server)

copy tftp: flash:

Address or name of remote host []?x.x.x.x

Source filename []?(copy n paste ur file name with .bin extension)

Destination filename?

It will start uploading IOS to ur flash:

verification

sh flash: or sh bootflash:/ sh supbootdisk:

Go to

conf t

boot system flash:(copy new ios name with .bin extension)

do wr

exit

#sh boor var

reload

I hop this is informative

Thanks

Ashish

Hi ,

forgote to mention Some good points ,If your using Window 7 please check firewall and you need to enable

telnet,ftp,tftp as by default they are turn off.

Please let us know if you still unable to upload IOS into switch.

Thanks

copy ftp:192.168.1.3/c:\c3750-ipbasek9-mz.122-55.SE1 flash:c3750-ipbasek9-mz.122-55.SE1

Hold on ... This is NOT the filename.

This command means "I want to copy the file 'c3750-ipbasek9-mz.122-55.SE1' and put into the flash as 'c3750-ipbasek9-mz.122-55.SE1'."

Ok, the command syntax could be correct (haven't used FTP option so wouldn't know if you can run the "C:\").

But do you have the file "c3750-ipbasek9-mz.122-55.SE1" or "c3750-ipbasek9-mz.122-55.SE1.BIN"???

This is possibly the reason why you are getting this error message.
