IP Interface Configuration

To configure IP interfaces, first set up VLANs, then access the IP Interface Settings menu located in the Layer 3 - IP

Networking subdirectory of the Advanced Setup folder.

Set Up IP Interfaces

Each VLAN must be configured prior to setting up the VLAN’s corresponding IP interface.

An example is presented below:

Table 3. VLAN Example – Assigned Ports

VLAN Name VID Switch Ports

System (default) 1 5, 6, 7, 8, 21, 22, 23, 24

Engineer 2 9, 10, 11, 12

Marketing 3 13, 14, 15, 16

Finance 4 17, 18, 19, 20

Sales 5 1, 2, 3, 4

Backbone 6 25, 26

In this case, 6 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:

Table 4. VLAN Example – Assigned IP Interfaces

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

The 6 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 Setup IP Interface window.

To setup IP Interfaces on the switch:

Go to the Advanced Setup folder, and click on the Layer 3 IP Networking link, and then click on the Setup IP Interfaces

link to open the following dialog box:
