WireShark - Packet capture on a single IP

I have a laptop with wireshark 1.10.1 running in my server room, attached to the switch where the system I want to packet sniff. How do I setup WireShark just to sniff what is coming out of 1 single IP address? Please advise.

Your question sounds odd "WireShark just to sniff what is coming out of 1 single IP address? Please advise"

I'm guessing you meant 1 interface/port, which wireshark can do and filter for your specific IP. Be sure to install winPcap.

Also have you set-up a span port to mirror everything to the port you are connected to?

Sorry yes... I want to capture what is coming out of 1 interface. By default is it capturing all DATA?
Yes, all data will be captured as winPcap will put the interface into promiscuous mode and accept all. You can then filter for specific IP,protocols or other.

Is that data easily readable or do I need something else make this happen?
Its easily readily human readable.

You should have a capture filter example in WireShark for filtering for a specific IP address, so it should be very easy for you to set it up (the example is called "IP address", the capture filter expression is "host" - replace the IP address with the one you want to monitor).
In WireShark you need to differ between display filters  - those can be set on the fly while capturing, and have a different syntax, but do not restrict the data captured, only what you see at the moment -  and capture filters, which will exclude anything from being captured which does not fit into the filter, reducing the amount of data.
If you're having a problem setting up the capture filter, try it in the settings for the interface itself, rather than Capture Options.
e.g.Wireshark - Capture Options (click for larger)Wireshark - Interface Settings
