Linksys EF1324 manual Port Statistics, Interfaces, Ethernet

Instant EtherFast® Series

Port Statistics

Port Statistics display key statistics from the Interfaces Group and Ethernet- like MIBs for each port. Error statistics on the traffic passing through each port are displayed. This information can be used to identify potential prob- lems with the Switch (such as a faulty port or unusually heavy loading). The values displayed have been accumulated since the last system reboot.

Select the required port.

Interfaces

•In Octets - The total number of octets received on the interface, includ- ing framing characters.

•In Unicast Pkts - The number of unicast packets delivered to a higher- layer protocol.

•In Non-Unicast Pkts - The number of non-unicast (that is, subnetwork- broadcast or subnetwork-multicast) packets delivered to a higher-layer protocol.

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

•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.

Ethernet

•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.

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