Re: To check specific port opened or not?

Hi

Im not quite sure what you are asking but if you want to check on your ASA, you can check your access lists to see if traffic on port 21 is allowed (inbound or outbound)

sh access-list (name of acl) | grep eq 21

this will search for anything in your access lists for port 21.
