Ethernet (ETH n) parameters
Rx Overruns
The number of receive overruns that have occurred on the Ethernet interface. An Rx overrun
occurs when there are not enough buffers to receive incoming packets which results in the
received packets being dropped.
Collisions
The number of times the router has detected a packet collision on the Ethernet network when
transmitting a packet.
Late Collisions
The number of times the router has detected a late packet collision on the Ethernet network
when transmitting a packet.
Flood Protection
The number of times the router has detected an Ethernet packet flood on the network and
has enabled the Flood Protection mechanism. Flood protection is designed to stop the router
from being overwhelmed by the sudden large increase in packets on the Ethernet network.
Alignment Errors
The number of alignment errors that have been detected when receiving an Ethernet packet.
FCS Errors
The number of Ethernet packets that have been received but had an invalid FCS.
Tx Deferred
The Ethernet packets successfully transmitted after being initially deferred.
Long Frames
The number of Ethernet packets that have been received which are too long.
Carrier Sense Error
The number of carrier sense errors that have occurred. These occur when the router attempts
to transmit an Ethernet packet but cannot detect the carrier sense condition on the Ethernet
network.
Rx MAC Errors
The number of internal errors that have occurred when receiving an Ethernet packet.
Tx MAC Errors
The number of internal errors that have occurred when attempting to transmit an Ethernet
packet.
Other Errors
The number of errors that have occurred which are not counted by the other statistics.
