Port configuration

How can I view which ports on the router are open for me and which are not

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"

do you mean for communication throught the router

how can I know which ports on the router are open for me and which ports are not.
Is the same concept be applied for the virtual ports in the windows os

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.
