The screen displays the VLAN ID and primary IP address for this interface.
8. 
In the Routing Interface list, select the interface.
9. 
In the Secondary IP Address field, add a secondary IP address to the selected interface.
10. 
In the Secondary IP Subnet Mask field, enter the subnet mask for the interface. 
This is also referred to as the subnet/network mask, and defines the portion of the 
interface’s IP address that is used to identify the attached network. This value is read-only 
once configured.

VLAN Overview
You can configure managed switch software with some ports supporting VLANs and some 
supporting routing. You can also configure the software to allow traffic on a VLAN to be 
treated as if the VLAN were a router port.
When a port is enabled for bridging (default) rather than routing, all normal bridge processing 
is performed for an inbound packet, which is then associated with a VLAN. Its MAC 
destination address (MAC DA) and VLAN ID are used to search the MAC address table. If 
routing is enabled for the VLAN, and the MAC DA of an inbound unicast packet is that of the 
internal bridge-router interface, the packet is routed. An inbound multicast packet is 
forwarded to all ports in the VLAN, plus the internal bridge-router interface, if it was received 
on a routed VLAN.
Since a port can be configured to belong to more than one VLAN, VLAN routing might be 
enabled for all of the VLANs on the port, or for a subset. VLAN routing can be used to allow 
more than one physical port to reside on the same subnet. It could also be used when a 
VLAN spans multiple physical networks, or when additional segmentation or security is 
required. This section shows how to configure the NETGEAR switch to support VLAN 
routing. A port can be either a VLAN port or a router port, but not both. However, a VLAN port 
can be part of a VLAN that is itself a router port.
