IP Interface Settings
Each VLAN must be configured prior to setting up the VLAN’s corresponding IP interface.
An example is presented below:
VLAN Name
VID
Switch Ports

Table 8- 1. VLAN Example - Assigned Ports
In this case, six IP interfaces are required, so a CIDR notation of 10.32.0.0/11 (or a 11-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).
Using a 10.xxx.xxx.xxx IP address notation, the above example would give 6 network addresses and 6 subnets. Any IP address
from the allowed range of IP addresses for each subnet can be chosen as an IP address for an IP interface on the switch. For this
example, we have chosen the next IP address above the network address for the IP interface’s IP Address:
VLAN Name
VID
Network Number
IP Address
System (default)
1
10.32.0.0
10.32.0.1
Engineer 2
10.64.0.0 10.64.0.1
Marketing 3
10.96.0.0 10.96.0.1
Finance 4
10.128.0.0
10.128.0.1
Sales 5
10.160.0.0
10.160.0.1
Backbone 6
10.192.0.0 10.192.0.1
Table 8- 2. VLAN Example - Assigned IP Interfaces
The six IP interfaces, each with an IP address (listed in the table above), and a subnet mask of 255.224.0.0 can be entered into the
IP Interface Settings window.
