6.3.1.5 Defining the IP address for the VNS (for the DHCP
server on the controller)
Bridged at the AP VNSs do not require the definition of a corresponding IP
address definition for the VNS since all traffic for users in that VNS will be directly
bridged by the AP at the local network point of attachment (VLAN at AP port).
The IP address definition is only required for a routed VNS or VLAN bridged VNS.
To define the IP address for the VNS:
1. From the main menu, click Virtual Network Configuration. The Virtual
Network Configuration page is displayed.
2. In the left pane Virtual Networks list, click the VNS you want to define the IP
address for. The Topology tab is displayed.
3. In the Gateway box, type the HiPath Wireless Controller's own IP address in
that VNS.
This IP address is the default gateway for the VNS. The HiPath Wireless
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
HiPath Wireless Controller's interface in their effort to route packets to an
external host).
For a VLAN bridged VNS, the IP address corresponds to the HiPath Wireless
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.
Note: If you are configuring Bridged at Controller VNS, the Gateway field
appears as Interface IP Addr on the user interface.
4. In the Mask box, type the appropriate subnet mask for this IP address to
separate the network portion from the host portion of the address (typically
255.255.255.0).
The following values to DHCP configuration are only applicable for
configurations if the controller is the DHCP server for users in the VNS—a
routed VNS or a VLAN bridged VNS with DHCP enabled (by default, DHCP
is disabled). These values are not visible for a bridged at AP VNS or a VLAN
bridged VNS with DHCP disabled (by default, DHCP is disabled).
The Address Range boxes (from and to) populate automatically with the
range of IP addresses to be assigned to wireless devices using this VNS,
based on the IP address you provided.
• To modify the address in the Address Range from box, type the first
available address.
