Example
Prior to FortiOS 5.0, to add SSH administrative access to an interface that currently allows HTTPS, FGFM and PING access, you would enter:
set allowaccess https fgfm ping ssh
In FortiOS 5.0, you can do this:
append allowaccess ssh
Similarly, to remove ping from the list, you would enter:
unselect allowaccess ping
To reset allowaccess to its default, you would enter:
clear allowaccess
