TFTP Broadcast on my Cisco SG200-08

[GillesNebel]

How do I disable TFTP broadcast's on my Cisco SG200-08 Series Router?

The reason I want to do this is because we have some EPSON printers that keep printing pages "Invalid TFTP operation, exiting firmware update". This is some kind of known issue with epson network card and cisco routers.

Thanks for your help

As Kasun pointed out that may work but generally no service config is already disabled by default in cli and can be seen if you issue show run all | i service
if its not definitely worth trying it , another option maybe to apply an ACL and block the TFTP packets to the printer so it cant initiate it

xxxxxxxxxxxx#sh run all | i service
no service log backtrace
no service config
no service exec-callback
no service nagle
service slave-log
