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:
