Switch Management and Operating Concepts
Note: An IP addressing scheme must be determined before
the IP interfaces can be setup on the switch. Some
consideration is required to arrive at an addressing scheme
that will suit the needs of a given network. Please see the
section titled IP Addressing and Subnetting in Chapter
5 for more information.
The Layer 3 switch allows ranges of IP addresse to be assigned to
VLANs. 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:

In this case, 6 IP interfaces (or 6 subnets) are required, so a CIDR
notation of 10.32.0.0/3 (or a 3-bit) addressing scheme will work.
This addressing scheme will give a subnet mask of
11111111.11100000.00000000.00000000 (binary) or 255.224.0.0
(decimal).
