The Interface Configuration wizard can be used to configure Ethernet and Serial interfaces. After selecting a proper interface type, the other parameters such as IP address, subnet mask can be specified.
Interface Type and Interface Number
You can specify IP address only after changing the global configuration mode to (config-if)#. Specify the interface type and interface number to change the mode to (config-if)# (interface configuration mode).
Primary IP Address
An interface can have one primary IP address. You can assign a primary IP address and a network mask to a network interface.
A mask identifies the bits that denote the network number in an IP address. When you use the mask to a subnet of a network, the mask is then referred to as a subnet mask.
Secondary IP Address
You can specify up to six secondary addresses. It assigns multiple IP addresses to network interfaces.
Source to Service
You can configure a router to transfer files between systems on the network using the File Transfer Protocol (FTP). When it is disabled, the no form of the command takes effect.
To allow the users to select address of an interface as the source address for Telnet connections. If it is not enabled, a "no" form of the command is sent to the device by default.
SNMP Link up/Link down trap
To enable Simple Network Management Protocol (SNMP) link trap generation. If it is not enabled, a "no" form of the command is sent to the device by default.
If you are selecting the Serial interface, the Encapsulation is enabled. It allows you to select a suitable Encapsulation type. Frame-relay, ppp and hdlc are provided and you can select one among them. In general, Frame-relay is used for Serial interface.
Note: If you are not enabling the services FTP, Telnet, and SNMP, the default command with no form will be sent to the device. For example, if the FTP service is not enabled then the command "no ip ftp source-interface" will be sent to the device.
The generated configuration commands are displayed when click "Apply" button and lets you append additional configuration commands for the selected device. Only the parameters applicable to the selected device are displayed.
Clicking this tab sends 'Show interfaces' command to the device and displays the result.
Click Apply and view the IOS configuration. If you select proper configuration tasks click OK to send the commands or Cancel not to send.
