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 terminal Router(config)#no service config Router(config)#exit Router#copy running-config startup-config Source : Cisco official related page
