Ethernet statistics based on the {{bibref|RFC2819}} ''RMON-MIB'' ''etherStatsTable'', with some extensions inspired by {{bibref|G.988|Section 9.3.32}}. Each instance is associated with an interface capable of transporting Ethernet-encapsulated packets, and contains a set of unidirectional Ethernet statistics. The statistics are sampled either on ingress or on egress. This is determined as follows: * If the instance is associated with an egress queue (or queues) via the {{param|Queue}} parameter or by setting {{param|AllQueues}} to {{true}} then data is sampled on egress. In this case {{param|Bytes}} etc measure the data that has been sent on the interface, possibly filtered by {{param|Queue}} or {{param|VLANID}}. * Otherwise data is sampled on ingress. In this case {{param|Bytes}} etc measure the data that has been received on the interface, possibly filtered by {{param|VLANID}}. When sampling on egress, the term ''received'' means ''received by the queuing sub-system''. Multiple instances can be associated with a single interface: individual instances can be configured to collect data associated with the entire interface, or with a particular VLAN and/or queue. The CPE MUST reset each instances's Stats parameters whenever the instance is disabled and re-enabled. Whether this reset occurs when the instance becomes operationally disabled ({{param|Status}} = {{enum|Disabled|Status}}) or administratively enabled ({{param|Enable}} = {{true}}) is a local matter to the CPE. This is similar to the behavior of interface statistics, e.g. as specified for {{object|Device.Ethernet.Interface.{i}.Stats}}. Furthermore, this instance's Stats parameters MUST be reset whenever the referenced interface's Stats parameters are reset, or when the referenced queue or VLAN is disabled and re-enabled. For enabled table entries, if {{param|Interface}} references an interface that is not capable of transporting Ethernet-encapsulated packets, or if {{param|Queue}} references a queue that is not instantiated on {{param|Interface}}, or if {{param|Queue}} is not a valid reference and {{param|AllQueues}} is {{false}}, the table entry is inoperable and the CPE MUST set {{param|Status}} to {{enum|Error_Misconfigured|Status}}. Note: The {{object}} table includes unique key parameters that are strong references. If a strongly referenced object is deleted, the CPE will set the referencing parameter to {{empty}}. However, doing so under these circumstances might cause the updated {{object}} row to then violate the table's unique key constraint; if this occurs, the CPE MUST set {{param|Status}} to {{enum|Error_Misconfigured|Status}} and disable the offending {{object}} row. Enables or disables this instance. The status of this instance. {{enum}} The {{enum|Error_Misconfigured}} value indicates that a necessary configuration value is undefined or invalid. The {{enum|Error}} value MAY be used by the CPE to indicate a locally defined error condition. {{datatype|expand}} The textual name of the {{object}} entry as assigned by the CPE. The interface associated with this instance. {{reference|an interface that is capable of transporting Ethernet-encapsulated packets}} The term "capable of transporting Ethernet-encapsulated packets" means "has an Ethernet header" and therefore refers to any interface that is at or below an ''Ethernet''.{{object|#.Link}} instance in the interface stack. Filter criterion. The VLAN ID for which statistics are to be collected. A zero value indicates that all packets, whether or not they have a VLAN header, will be considered. A non-zero value indicates that only packets that have the the specified VLAN ID will be considered. Filter criterion. The egress queue with which this instance is associated. Only packets that are sent to the referenced queue will be considered. Indicates whether this instance applies to all queues. If {{true}}, the value of {{param|Queue}} is ignored since all egress queues are indicated. The total number of events in which packets were dropped due to lack of resources. Note that this number is not necessarily the number of packets dropped; it is just the number of times this condition has been detected. This parameter is based on ''etherStatsDropEvents'' from {{bibref|RFC2819}}. The total number of {{units}} (including those in bad packets) received (excluding framing bits but including FCS bytes). This parameter is based on ''etherStatsOctets'' from {{bibref|RFC2819}}. The total number of {{units}} (including bad packets, broadcast packets, and multicast packets) received.

Note that this does not include multicast packets. This parameter is based on ''etherStatsBroadcastPkts'' from {{bibref|RFC2819}}.
