Tags allow you to group
objects using keywords or phrases. You can apply tags to
address objects,
address groups (static and dynamic), zones,
services,
service groups, and to policy rules. You can also use an SD-WAN Interface
profile to apply a link tag to an Ethernet interface. You can use tags to sort or filter objects
and to visually distinguish objects by color. When you apply a color to a tag, the Policy tab
displays the object with a background color. Each object can have up to 64 tags. When an object
has multiple tags, it displays the color of the first tag applied.
