Linksys Etherfast manual Ethernet-Like

EtherFast® Series

•In Errors - The number of inbound packets that contained errors pre- venting them from being deliverable to a higher-layer protocol.

•Alignment Errors - The number of alignment errors (mis-synchronized data packets).

•Out Octets - The total number of octets transmitted out of the interface, including framing characters.

•Out Unicast Pkts - The total number of packets that higher-level proto- cols requested be transmitted to a subnetwork-unicast address, including those that were discarded or not sent.

•Out Non-Unicast Pkts - The total number of packets that higher-level protocols requested be transmitted to a non-unicast (that is, a subnet- work-broadcast or subnetwork-multicast) address, including those that were discarded or not sent.

•Out Discards - The number of outbound packets which were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a packet could be to free up buffer space.

•Out Errors - The number of outbound packets that could not be trans- mitted because of errors.

•CRC Errors - Number of Ethernet Cyclic Redundancy Check errors detected by this device.

•Single Collisions - The number of successfully transmitted frames for which transmission is inhibited by exactly one collision.

•Deferred Transmissions - A count of frames for which the first trans- mission attempt on a particular interface is delayed because the medium was busy.

•Excessive Collisions - The number of frames for which transmission failed due to excessive collisions.

EtherFast® Managed 24-Port with Dual Gigabit Switch

•Drop Events - The total number of events in which packets were dropped due to lack of resources.

•Octets - Number of octets passing through this port.

•Multiple Collisions - A count of successfully transmitted frames for which transmission is inhibited by more than one collision.

•Late Collisions - The number of times that a collision is detected later than 512 bit-times into the transmission of a packet.

•Carrier Sense Errors - The number of times that the carrier sense con- dition was lost or never asserted when attempting to transmit a frame.

•Fragments - The total number of frames received that were less than 64 octets in length (excluding framing bits, but including FCS octets) and had either an FCS or alignment error.

•Jabbers - The total number of frames received that were longer than 1518 octets (excluding framing bits, but including FCS octets), and had either an FCS or alignment error.
