TFTP Service

Question:

i am trying Cisco 3945 router to find a way to verify that the TFTP service is not running on the router.  i issued the no tftp-server flash: <ios> and it accepted it even though it does not show up in the show running config.   any docs would be helpful.    

Answer:

If the command isn't in the running config, it's disabled. The tftp server isn't turned on by default. There are version differences that seem to either support the control-plane command and those that don't. I have a 3845 that has it, but I have a 3825 that doesn't. Here's a 3745 that does that would show you the results should you decide to maybe update your router:

R1#sh control-plane host open-ports
Active internet connections (servers and established)
Prot        Local Address      Foreign Address                  Service    State
tcp                 *:23                  *:0                   Telnet   LISTEN
udp                 *:69                  *:0              TFTP-Server   LISTEN

R1#  Cisco 3945 price
