Creating The Vlan Routing Interface - D-Link Unified Access System DWS-3000 Series User Manual

the wireless interface on the switch, it is essentially a permanent logical inter-
face and cannot have an IP address of 127.0.0.1. You must create a dedicated
subnet for the loopback interface, and other devices on the network must be
able to contact the IP address of the loopback interface.
You must create static routes so other devices can find the loopback interface.
The advantage of defining a loopback interface is that the interface never goes down. The
disadvantage is that network configuration is more complex because the loopback interface is
located on its own subnet and the rest of the network must know how to get to the subnet.
The network must have routes between the WCS and the APs to manage. The APs must be
able to ping the IP address of the loopback interface used as the WLAN interface on the WCS.
The following procedures show an example of how to enable routing and configure an IP
address on a loopback or routing interface.
1. Log on to the CLI and switch to Global Config mode:
(System-Prompt)
User: admin
Password:
(System-Prompt) >enable
Password:
(System-Prompt) #config
(System-Prompt) (Config)#
2. Enable routing.
(System-Prompt) (Config)#ip routing
3. Change to Interface Config mode for loopback interface 0, and assign an IP address and
subnet mask.
(System-Prompt) (Config)#interface loopback 0
(System-Prompt) (Interface loopback 0)#ip address 192.168.100.15 255.255.255.255
You can also use the Web interface or SNMP to enable routing and configure an IP address.
The following example shows the procedures to enable routing and configure an IP address on
the switch by using the Web interface.
1. Log on to the Web interface and click Routing > IP > Configuration to access the IP
Configuration page.
2. From the Routing Mode drop-down menu, choose Enable, and then click Submit.
3. To create a loopback interface, click Routing > Loopback > Configuration.
4. From the Loopback drop-down menu, choose Create, and then click Submit
5. Enter an IPv4 address and subnet mask in the appropriate fields, and then click Submit.

Creating the VLAN Routing Interface

The D-Link WLAN Controller Switch and the D-Link Access Point support Virtual LANs
(VLANs) to provide the logical separation of a physical network. You can use VLANs to
segment the wireless network on a per-VAP basis. VLAN routing interfaces allow VLANs to
span across different subnets, which is useful for L3 Tunneling.
