Pull Configs for a series of Switches with TFTP open original image

Hello,



I have inherited a problem or potential problem. We have not been very good at backing up our switch configurations. We have a number of cisco switches throughout three large offices. I would like to backup the configurations in a central location so if a switch fails, I can push the configuration back out with minimal downtime.



What I would like to do is copy the running configuration to the startup config, then pull the config to a central server.



Is there a way to do this easily? I would like to be able to pass in a series of IP addresses for the switches (four different subnets and in three different physical locations).



Thanks.



Kevin

Write an "expect" script. I regularly use that for similar things.

Thank you very much! That is perfect! I have now written a python script that uses pexpect (python's expect) that takes a file of the switches, goes out, does a write mem, then is set to TFTP it to the server with the switch name & date.

Now, and perhaps this isn't the best place to ask this but I prefer the opinions here over a Windows board, what is the best TFTP to set up on a Windows 2003 server?

Thanks again!

Have a look at rancid - it stores the configs using CVS, so you may even restor a config from e few months ago.

I have used tftpd32

for decades, it seems like. Other than feature creep no problems at all. I would consider an older version to avoid having to worry about dhcp server, bootp server etc.

Maybe version 2.2?

This may of course cause other issues - not sure.

You can turn off the bits you don't want. It is very small and did not previously require installation. No idea about the latest Open Source versions - hopefully all you need still is the .exe.

My prefered TFTP utility for Windows platforms is 3cdaemon from 3com -

It includes TFTP, FTP & SYSLOG Clients and Servers so its quite usable and I have it permanently running on my laptop. It also supports TFTP transfers larger than 16MB, something that others frequently do not. An excellent utility.

Cheers.............................pk.
