ip subinterface


Subinterfaces are virtual interfaces created by dividing one physical interface into multiple logical interfaces. They are used for a variety of purposes, such as assigning a different IP address to each subinterface and creating multiple broadcast domains on a single physical interface. 1 To configure a subinterface, an interface number and a tag need to be assigned, with the tag matching the VLAN exactly. 2 The interface should then be added to the 'default' Virtual Router and assigned to the 'trust' Security Zone. 2

For ease of management, it's best to set it the same id as the VLAN tag. Add the interface to the 'default' Virtual Router and assign it to the 'trust' Security Zone.
