statistics:
EN Rx Packets: The number of Ethernet packets received.
EN Rx Errors: The number of bad Ethernet packets received.
EN Collisions: An error occurring when Ethernet packets are transmitted simultaneously by nodes on the LAN.
WAN Connection Statistics
The WAN Connection Statistics give the following information about each channel of the point-to-point inter face:
■ The number of bytes and packets received through the channel
■ The number of bytes and packets transmitted through the channel
Event Histories
The Netopia R2121 records cer tain relevant occurrences in event histories. Event histories are useful for
diagnosing problems because they list what happened before, during, and after a problem occurs. You can view
two different event histories: one for the router’s system and one for the WAN. The Netopia R2121’s built-in
batter y backup prevents loss of event histor y from a shut down or reset.
The Router’s event histories are structured to display the most recent events first, and to make it easy to
distinguish error messages from informational messages. Error messages are prefixed with an asterisk. Both
the WAN Event Histor y and the Device Event Histor y retain records of the 128 most recent events.
To go to the Event Histories screens, select either WAN Event History or Device Event History in the Statistics
& Logs screen.
