+# `add_vlan` Command
+
+## Name
+
+`add_vlan`
+
+## Synopsis
+
+```
+add_vlan ${card} ${vlan}
+```
+
+## Description
+
+Adds an internal network segment with the specified vlan on the specified
+card.  For example, `add_vlan xy0 123` has the effect of
+`vlans_xy0="${vlans_xy0} 123"`.
+
+The internal implementation prevents adding duplicate VLAN ID's to the same
+adaptor, by checking for their presence before adding.  It can safely be
+used alongside manual changes to `rc.conf` changes to these variables.
