USRobotics NETServer/8, NETServer/16 manual Ifconfig

Ifconfig

This command displays the current (active) configuration of an interface. Note that the configuration of a serial port is only displayed when there is an established point-to-point connec- tion using that serial port. That is, an established connection with S1 would show up as ptp1 (point-to-point connection 1)

Ifconfig also lets you reconfigure the NETServer interfaces while they are active. Note that this affects configuration for the currently active connection only. When the connection is terminated, the port reverts to its normal configuration.

Viewing an Active Interface

To view an interface’s active configuration, use the following command:

ifconfig <interface>

If you type the command without a specific interface, the active configuration of all interfaces appears. The first line of the active configuration contains the name of the interface (net0, ptp1, and so on), as well as various flags that indicate its status:

IP_Up/Down	Indicates whether IP and IPX are being used
IPX_Up/Down	by the NETServer on this interface.
Broadcast	The interface is connected to a broadcast
	network (e.g., Ethernet) rather than a point-to-
	point link.
Point_to_Point	The interface is part of a PPP or SLIP link.
Suspended	The interface is an on-demand dial out link.
	However, the connection has been torn down
	because there is no current traffic. The logical
	connection is maintained to preserve routing
	data.
Listen	RIP packets are being received through this
	interface.
RIPsend	RIP is being sent through this interface.
Private	No RIP information is being exchanged
	through this interface.
