Using Diagnostic Pages
• Carrier Sense Lost—The number of disconnects from the Ethernet network.
Carrier sense lost events are usually caused by disconnected wiring.
• Late Collisions—Packet errors that probably were caused by over-long
wiring problems. Late collisions could also indicate a failing NIC card.
• Overrun Packets—Ethernet packets that were discarded because the access
point had a temporary overload of packets to handle.
• Packets Too Long—Ethernet packets that were larger than the maximum
packet size of 1518 bytes.
• Packets Too Short—Ethernet packets that were shorter than the minimum
packet size of 64 bytes.
• Packets Truncated—Corrupt or incomplete packets.
Transmit Statistics
• Unicast Packets—The number of packets transmitted in point-to-point
communication.
• Multicast Packets—The number of packets transmitted that were sent as a
transmission to a set of nodes.
• Total Bytes—Total number of bytes transmitted from the port.
• Total Errors—The number of packets determined to be in error.
• Discarded Packets—The number of packets discarded by the access point due
to errors or network congestion.
• Forwarded Packets—The number of packets transmitted by the port that were
acceptable or passable through the filters.
• Max Retry Packets—Packets which failed after being retried several times.
• Total Collisions—The number of packet collisions that occurred through this
port.
• Late Collisions—Packet errors that were likely caused by overlong wiring
problems. Could also indicate a failing NIC card.
• Underrun Packets—Packets failed to be sent because the access point was
unable to keep up with the Ethernet controller.
