3550 tftp backup issue

[sapper1]

We have multiple catalyst 3550 switches and I am trying to backup the configs on them just in case. I have been able to successfully backup some of them to my tftp server but I am having some trouble with the others. Below is the command I am using and the out put I get when I run it the first time. After I run it the first time if I try to run the command again I receive a message stating that the file already exists but it is no where to be found on my tftp server. Any help would be greatly appreciated.

copy system:/running-config 10.0.0.6
Destination filename [10.0.0.6]? test
6310 bytes copied in 0.676 secs (9334 bytes/sec)

copy system:/running-config 10.0.0.6

Just wondering, my tftp server shows the incoming connections and file transfers in real time. Does your tftp server show the incoming connection and file transfer as your trying it?

 

[sapper1]

The tftp software that I am using is called tftpd32 and I do not see any activity on it when I try to backup the config. I am not even able to ping any of my machines from the switches I am having problems with.

One thing I did notice is that the files are being written to flash on the switches.

 

[vipergg]

Syntax is incorrect , the easiest way is the following. with your syntax that is all you are doing is to copy your config into flash on the switch .

write net
it will assk you for the address of the server
enter
it will then ask you the filename , input the name and then just hit enter a coupe of times.


another option :
copy run tftp: , enter
enter adress, enter
enter filename and hit enter.

 

[burtsbees]

Yes---you're missing the tftp part...

copy run tftp://10.0.0.6

or

copy run tftp

and answer the parameter questions.

The syntax and the command are correct. I have backed up my other switches the exact same way and it has worked fine.

When I try to use the wr net command I receive the message that "This command has been replaced with copy system:/running config" once I enter in this command I am then prompted for the IP address of my server and the destination file name. All swithces are using the same IOS version and everything. When I have a problem backing up the config I run the ping command from the switch and I am unable to ping my tftp server. Even if I am connected directly to the switch.

I don't know if it has something to do with the way our vlans are setup or what. I'll copy and paste a config of one of the problem switches later and see what you all make of it.

 

[sapper1]

Here is my putty log file of a successful backup of one of my switches. You will be able to see what commands I have used to perform the bakcup as well as the config of the switch. I will post a putty log for a switch that I am having trouble with shortly.

Forgive me - I Haven't scanned in great detail but I raised a TAC case last year for a similar problem with 6500 switches and a particular version of ION (notIOS) software which exibited the same problem. We proved it was a software/Cisco conflict by running a sniff on the TFTP and finding that as the Cisco started it's tftp it always sent out the initiation packet with the filename twice - SO tftpd32 opened one file then failed on the second packet as it had already opened it.

If we used cisco's own (and rather rubbish) tftp program it worked fine as that (and from memory an old 3com tftp proggy) ignored the double request. Cisco were blaming the TFTPD32 software as other packages worked but eventually they admitted there was also a bug in ION which we upgraded - all ok now.

It's worth checking the IOS versions on those that don't work agains those that do and if you can do it sniff the exchange too.

Here is the vesion information on the switch that I can backup.

[tjbradford]

sounds like its trying to use a different vlan than the one that the tftp server is on.

 

[sapper1]

That could be but I can't even ping devices that are on the same vlan and connected directly to the switch. And all devices that are connected to the switch are working fine as far as network connectivity goes. I am getting to the point where I am just going to go to each switch and copy the results of show config to a text file. This will take a little longer but at least I'll get some kind of a backup.

 

[tjbradford]

sounds very odd, what O/S are you running the tftp server from, is there a firewall on it ?

whats the end to end hardware ?
laptop ------ switch --fiber -- switch ------- desktop ?

 

[sapper1]

Windows XP with no firewall. I have also used a Vista PC with the firewall disabled as well. Some of my switches have no problems at all backing up to either of these while other switches will not backup to them at all.

 

[burtsbees]

Where is

int vlan 10
ip add 10.0.8.x x.x.x.x

???

Obviously, you know that your switch cannot ping the node at 10.0.8.x, and I am assuming this is vlan 10? If so, where in the configs are you telling the switches where and what vlan 10 is? If it's not vlan 10, then what is 10.0.8.x? I sure don't see where anything knows where or what that is, and I can only assume it gets the vlan info through a trunk...

Burt

 

[sapper1]

I guess that would be some helpful info.

Our core switch is a catalyst 6500 switch that is acting as our DHCP server and vlan router. All vlans are setup and managed from this switch. If I am looking at the config of the 6500 correctly vlan 10 is in the 10.0.0.x subnet and the 10.0.8.x subnet is assigned to vlan 18.

 

[tjbradford]

i think it might pay to get a backup via a console connection, blat the config and place a minimal config in its place ie
int vlan 1
ip address 10.0.0.1 255.0.0.0
no shut

plug in your pc (10.0.0.2) to fast 0/0 which will be on vlan 1 by default

try to backup your config from that.
