You can use csup as explained in section 4.5.1.  This will update the
Ports Collection  you installed from CD/DVD
by fetching only the required newer files

Or, you can use portsnap too like this:

First time:
portsnap fetch extract

Subsequent times:
portsnap fetch update


If you are starting with an empty Ports tree (for example you skipped
installing it from CD during sysinstall) portsnap will be faster than
csup. (Note you can start with an empty tree and csup as well)

Anytime you decide to switch from csup to portsnap, always perform an
'extract'

In section 4.5 as you noticed already. Portsnap is also revisited in
chapter 24:
