Interfaces Tab

The Interfaces Tab displays information about the Ethernet LAN, PPP channel and Ethernet WAN interfaces.

Ethernet LAN interface

The Ethernet LAN interface is the router's interface for the LAN side or "private" side of your Internet connection which is exposed directly to your PC(s). The interface number is identified in square brackets after the name.

PPP channel interface

The PPP channel interface is the router's interface for the special "ppp_device". The interface number is identified in square brackets after the name.

Ethernet WAN interface

The Ethernet WAN interface is the router's interface for the WAN side or "public" side of your Internet connection which is exposed directly to the Internet. The interface number is identified in square brackets after the name.

Details displayed

The same details are displayed for each of these three interfaces.

Status

The current operational state of the interface: up, down or testing. The testing state indicates that no operational packets can be passed.

Last change

This displays how long since the interface entered its current operational state. It is shown as Days:Hours:Minutes:Seconds.

MTU size

The size of the largest datagram which can be sent/received on the interface, specified in octets. For interfaces that are used for transmitting network datagrams, this is the size of the largest network datagram that can be sent on the interface.

IN

This displays the amount of traffic in megabytes or gigabytes received on the interface including framing characters.

OUT

This displays the amount of traffic in megabytes or gigabytes transmitted out of the interface including framing characters.

inErrors

This displays the number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol.

OutErrors

This displays the number of outbound packets that could not be transmitted because of errors.

InUnknownProtos

This displays the number of packets received via the interface which were discarded because of an unknown or unsupported protocol.

OutQLen

This displays the current length of the output packet queue in packets.

Help

The "Help" button will display the context-sensitive help file for this tab. Pressing F1 at any time will also display the context-sensitive help file.

Update

The "Update" button will update the information displayed in this tab. To set the display in this tab to update automatically every 5 to 60 seconds, see the Interfaces item in the Options Menu.
