Back to the top ### IP Addresses for VLANs VLANs allow you to group your network users and resources by function, team, or application. For example, you can restrict specific data broadcasts to specific logical workgroups for security purposes, such as keeping information about employee salaries only to devices in a VLAN created for payroll-related communications. For more information about VLANs, see the VLANs window. On a multilayer switch, a VLAN interface is a logical interface on a switch that is associated with one VLAN. You can use VLAN interfaces to route between two VLANs connected to a switch without the use of a router. Back to the top ### IP Addresses for Routed Ports On a multilayer switch, ports can be configured as routed ports. A routed port is a physical port 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 switch port can take place. Back to the top ### Assign an IP Address to a VLAN or to a Routed Port
Interface Name | The ports in the Interface column are either VLANs or routed ports. The name and number of the VLAN through which traffic on the port will be managed. The number of the routed port on a multilayer switch. For example: Fa1/1 is Fast Ethernet port 1 on the base switch. Fa2/1 is Fast Ethernet port 1 on the first switch expansion module. Fa3/1 is Fast Ethernet port 1 on the second switch expansion module.
Routed | Select the check box to configure the interface as a routed port. By default, the check box is not selected. This check box is available on multilayer switches.
IP Address | The IP address is a unique identifier for the VLAN or 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 the VLAN 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 or routed port belongs. Subnets are used to segment the devices in a network into smaller groups. The default is 255.255.255.0.
