If you are like many users of the latest IOS, you may find your routers constantly outputting a mesage like this:
%Error opening tftp://255.255.255.255/cisconet.cfg (Timed out)
19:20:43: %SYS-4-CONFIG_RESOLVE_FAILURE: System config parse from (tftp://255.255.255.255/cisconet.cfg) failed
The reason for this message is the router is attempting to autoload the configuration files after a restart.
So to disable the autoloading of configuration files simply add the following to the configuration of the router:
Router(config)# no service config
If this is not the issue, then we would investigate why the TFTP load is failing.
Hope this helps!
