[rancid] Restore config on cisco devices

[simon ben]

 Dear Heasley 
Thanks for your quick reply. 
just wanted to know regarding the alternate way mentioned by you after doing a minimum config for the cisco switch or router for network connectivity as guess it would be a better option
Is it possible to restore the config from viewvc screen from the browser as I dont see any option neither no option to down and save it as a file on my local desktop pc
appreciate your advice and help if the restore could be done from viewvc screen or if any tool is available with viewvc to achieve this
Thanks and Regards
simon

Yes, in general this works.  If you have configured rancid to filter
passwords or other configuration contents, then those must be restored
separately.  And, there are a few devices that simply have bugs (imo)
that do not permit the configuration they display to be loaded in their
entirety; ISTR procurve being one.

Another way to restore the config, instead of cut/paste, is to apply
the minimal config to the device for network connectivity, then use
http/rcp/ftp/tftp to load the config.  Not all devices support this.
