in show port command itself you can find these details.

If the port is connected to some device then it will show "connected" otherwise it will show "Disconnected". If its administratively disabled then it will show "Disabled"

HI,

what do you mean by ports ? Are you talking about physical ports (interfaces) ? or application ports ? ( ex: telnet for 23).


If you talking about physical ports. use the command "show ip interface brief" . It will tell you which ports are 'up' (already connected ) and which ports 'down' ( not yet connecetd or may be problem in the existing connection ) .

so the ports which are in 'down' state may be the 'open' ports in the router. :)
