The Interfaces page displays generic performance data for the actual physical LAN, WAN, and management interfaces (primary and secondary). It answers the following questions:
From the Monitoring menu, select Interfaces. The page displays the actual statistics accumulated for wan0, lan0, mgmt0, and mgmt1 since the appliance’s last reboot.

The Interfaces page displays the following statistics:
|
Number of packets received inbound from the WAN side, including all packets that were either discarded, contained errors, arrived too quickly for the hardware to receive, or were frame or mcast packets,
|
|
|
Number of times the receiver hardware was unable to hand a received packet to a hardware buffer because the rate exceeded the receiver's ability to handle the data.
|
|
|
Number of packets received incorrectly having a CRC error and a non-integer number of octets. On a LAN, this is usually the result of collisions or a malfunctioning Ethernet device.
|
|
Number of packets transmitted outbound toward the WAN side, including all packets that were either discarded, contained errors, were overrun, had collisions, or were dropped because the interface detection link is lost.
|
|
|
Number of times the transmitter hardware was unable to hand a transmitted packet to a hardware buffer because the rate exceeded the transmitter's ability to handle the data.
