Back to the top ### IP Addresses for VLAN Interfaces A VLAN interface is a logical interface on the switch that is associated with one VLAN. VLANs allow you to group your network users and resources by function, team, or application. If the switch is operating as a DHCP server, the devices in a VLAN receive IP addresses from the DHCP IP address pool in the same subnet as the VLAN IP address. For more information about VLANs, see the VLANs window. For more information about DHCP, see the DHCP window. On a Layer 3 switch, you can use VLAN interfaces to route between two VLANs connected to the switch without the use of a router. VLAN interfaces must have IP addresses assigned directly to them to allow communication with the hosts on those interfaces that use IP. Back to the top ### IP Addresses for Routed Ports A routed port is a physical port on a Layer 3 switch that acts like a port on a router; it does not have to be connected to a router. Routed ports must have IP addresses assigned directly to them to allow communication with the hosts on those interfaces that use IP. Back to the top ### Enable IP Routing By default, IP routing is disabled on the switch (the Enable Routing check box is not selected). Select the check box to enable IP routing so that routing on a VLAN interface or routed port can take place. Back to the top ### Assign an IP Address to a VLAN Interface or to a Routed Port
Interface Name | The name of the VLAN interface through which traffic on the port will be managed, or the number of the routed port on a Layer 3 switch.
Routed | Select the check box to configure the interface as a routed port. By default, the check box is not selected.
IP Address | The IP address is a unique identifier for the VLAN interface or the routed port. The format is a 32-bit numeric address written as four numbers separated by periods. Each number can be from 0 to 255. Make sure that the IP address that you assign to the VLAN interface or routed port is not being used by another device in your network.
Subnet Mask | The subnet mask is the network address that identifies the subnetwork (subnet) to which the VLAN interface or routed port belongs. Subnets are used to segment the devices in a network into smaller groups. The default is 255.255.255.0.
