Show run | redirect FTP: creates 0b file

[bbtMichaelR]

I am running into an issue with trying to backup my configuration (on several switches).

If I run the following, I get a new empty file on the FTP server

show run | redirect ftp://user:pass@10.10.10.1/myconfig.txt

if I do a copy runn  ftp://user:pass@10.10.10.1/myconfig.txt, it works just fine, but requires manual input to confirm the address and filename

I'm trying to accomplish this with a kron schedule, but right now I can't even get it to work from the console.  I had thought that it was because I wasn't granting modify access on the ftp server (and assumed that maybe the redirect option might be appending to a file line by line), but when I granted full access, I still have the same issue.  The file gets created just fine, it just has nothing in it.

I'm fairly certain there is a mistake I'm making since I have tried this on multiple switches with the same result.  The switch I'm testing on now is (C3560 Boot Loader (C3560-HBOOT-M) Version 12.2(44)SE5)

I found instructions for setting this up at http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_tech_note09186a008020260d.shtml#ftp  but haven't been able to find any resources on troubleshooting the redirect pipeline command

Hello Michael,

Did you resolve the problem?
The command syntax seems OK. Did you try to debug the file transfer with "debug ip ftp"?

Best regards,

César.

I get the following when I turn on debug ip ftp:

Hi,

Can you do the same debug when you do the copy command.

Regards.

I also noticed, that if I take the username and password from the url, and specify them with the ios commands (IP FTP User/Pass), it works fine

I must have just missed the error earlier, because when I try that now, it still fails

Hi,

What about the sh run | tee and sh run | append commands are they also failing?

Regards.

Alain.

[bbtMichaelR]

yes, both fail also.

tee does write the config to the console, just fails on the FTP transfer

[cadet alain · Accepted solution]

Have all switches involved the same IOS version ?

Regards.

Alain.

[bbtMichaelR]

yes, all are the same version

just now tried it from a router, and it worked fine

think it is a bug in the IOS version I'm running??

Cisco IOS Software, C3560 Software (C3560-IPSERVICESK9-M), Version 12.2(53)SE, RELEASE SOFTWARE (fc2)

I get exactly the same thing, but when trying to redirect or tee output from 'show tech-support' to flash:

show tech-support | redirect flash:filename.txt

Feb  1 02:44:31.739: %SYS-3-URLWRITEFAIL: redirection url write failed 'No space left on device'

But if I look at the flash device, its got 6MB of space left:

The version of IOS running in the switch doesn't support the 'squeeze' command, so I can't do that. Any thoughts?
