IP Address Configuration

The L3 (IP) address definition is only required for Physical port and Routed topologies. For Bridge Traffic Locally at EWC topologies, L3 configuration is optional. L3 configuration would be necessary if services such as DHCP (Dynamic Host Configuration Protocol), captive portal, AP registration (with up to 4 topologies) are required over the configured network segment or if controller management operations are intended to be done through the configured interface.

Bridge Traffic Locally at AP topologies can define a Mask and do not require the definition of a corresponding IP address since all traffic for users in that VNS will be directly bridged by the AP at the local network point of attachment (VLAN (Virtual LAN) at AP port).

To define the IP address for the topology:

From the top menu, click Controller> Topologies, or VNS > Topologies.
Click New to create a new topology or select the topology you want to define the IP address for. The Topologies window is displayed. Depending on the preselected options, two or three tabs are displayed.
Configuring IP Address for Routed Topology
For IP interface configuration for Routed topologies, configure the following Layer 3 parameters.
1. In the Gateway field, type the controller's own IP address in that VNS. This IP address is the default gateway for the VNS. The controller advertises this address to the wireless devices when they sign on. For routed VNSs, it corresponds to the IP address that is communicated to MUs (in the VNS) as the default gateway for the VNS subnet. (MUs target the controller's interface in their effort to route packets to an external host.)
  Note
  The Gateway field only supports IPv4 addresses.
2. In the Mask field, type the appropriate subnet mask for the IP address. This separates the network portion from the host portion of the address (typically, 255.255.255.0).
3. If desired, enable Management traffic.

IP Address for Bridged Traffic Locally

In the Interface IP field, type the IP address that corresponds to the controller's own point of presence on the VLAN. In this case, the controller's interface is typically not the gateway for the subnet. The gateway for the subnet is the infrastructure router defined to handle the VLAN.
In the Mask field, type the appropriate subnet mask for the IP address. This separates the network portion from the host portion of the address (typically, 255.255.255.0).
Configure Strict Subnet Adherence.
If desired, configure AP Registration. If selected, wireless APs can use this port for discovery and registration.
If desired, enable Management traffic.
