After modifying a Cisco (router/switch) equipment's configuration it's possible that the configuration service of the equipment activates. This services will generate TFTP (Trivial File Transfer Protocol) broadcast requests on all interfaces of the equipment looking for a configuration on the network. It generates the following log message on the equipment:
- %Error opening tftp://255.255.255.255/network-confg
- %Error opening tftp://255.255.255.255/cisconet.cfg
- %Error opening tftp://255.255.255.255/3620-confg
- %Error opening tftp://255.255.255.255/3620.cfg
This service can be annoying if you have a TFTP server running on your network as it will try to reply to those requests ; moreover, it slows down equipment's boot time as it will wait for requests to be replied or time out to finish booting up.
To disable that service use the following commands:
Router(config)#no service config
Router#copy running-config startup-config

It may be pretty complicated, but if you will allot time to understand it even more, I am pretty sure that you will get the gist of the post. All you need to do is to make an effort for it and it will happen!
For some locales it is compulsory to transfer an image as well. All correspondence happens through the part profile. Thus you are by and large not requested to present any private contact data for example email address.
