Setting up IP Interfaces

The Layer 3 switch allows ranges of IP addresses (OSI layer 3) to be assigned to VLANs (OSI layer 2). Each VLAN must be configured prior to setting up the corresponding IP interface. An IP addressing scheme must then be established, and implemented when the IP interfaces are set up on the switch.

An example is presented below:

	VLAN Name	VID	Switch Ports
	System (default)	1	5, 6, 7, 8, 21, 22, 23, 24
	Engineering	2	9, 10, 11, 12
	Marketing	3	13, 14, 15, 16
	Finance	4	17, 18, 19, 20
	Sales	5	1, 2, 3, 4
