This version published as RFC 2819."; } revision "1995-02-01" { description "Bug fixes, clarifications and minor changes based on implementation experience, published as RFC1757 [18]. Two changes were made to object definitions: 1) A new status bit has been defined for the captureBufferPacketStatus object, indicating that the packet order within the capture buffer may not be identical to the packet order as received off the wire. This bit may only be used for packets transmitted by the probe. Older NMS applications can safely ignore this status bit, which might be used by newer agents. 2) The packetMatch trap has been removed. This trap was never actually 'approved' and was not added to this document along with the risingAlarm and fallingAlarm traps. The packetMatch trap could not be throttled, which could cause disruption of normal network traffic under some circumstances. An NMS should configure a risingAlarm threshold on the appropriate channelMatches instance if a trap is desired for a packetMatch event. Note that logging of packetMatch events is still supported--only trap generation for such events has been removed. In addition, several clarifications to individual object definitions have been added to assist agent and NMS implementors: - global definition of 'good packets' and 'bad packets' - more detailed text governing conceptual row creation and modification - instructions for probes relating to interface changes and disruptions - clarification of some ethernet counter definitions - recommended formula for calculating network utilization - clarification of channel and captureBuffer behavior for some unusual conditions - examples of proper instance naming for each table"; } revision "1991-11-01" { description "The original version of this MIB, published as RFC1271."; } smiv2:oid "1.3.6.1.2.1.16.0"; smiv2:alias "rmon" { smiv2:oid "1.3.6.1.2.1.16"; } smiv2:alias "rmonEventsV2" { description "Definition point for RMON notifications."; smiv2:oid "1.3.6.1.2.1.16.0"; } smiv2:alias "statistics" { smiv2:oid "1.3.6.1.2.1.16.1"; } smiv2:alias "history" { smiv2:oid "1.3.6.1.2.1.16.2"; } smiv2:alias "alarm" { smiv2:oid "1.3.6.1.2.1.16.3"; } smiv2:alias "hosts" { smiv2:oid "1.3.6.1.2.1.16.4"; } smiv2:alias "hostTopN" { smiv2:oid "1.3.6.1.2.1.16.5"; } smiv2:alias "matrix" { smiv2:oid "1.3.6.1.2.1.16.6"; } smiv2:alias "filter" { smiv2:oid "1.3.6.1.2.1.16.7"; } smiv2:alias "capture" { smiv2:oid "1.3.6.1.2.1.16.8"; } smiv2:alias "event" { smiv2:oid "1.3.6.1.2.1.16.9"; } smiv2:alias "rmonConformance" { smiv2:oid "1.3.6.1.2.1.16.20"; } smiv2:alias "rmonMibModule" { smiv2:oid "1.3.6.1.2.1.16.20.8"; } smiv2:alias "rmonCompliances" { smiv2:oid "1.3.6.1.2.1.16.20.9"; } smiv2:alias "rmonGroups" { smiv2:oid "1.3.6.1.2.1.16.20.10"; } typedef OwnerString { type binary { length "0..127"; } description "This data type is used to model an administratively assigned name of the owner of a resource.

Setting this object to the value invalid(4) has the effect of invalidating the corresponding entry. That is, it effectively disassociates the mapping identified with said entry. It is an implementation-specific matter as to whether the agent removes an invalidated entry from the table. Accordingly, management stations must be prepared to receive tabular information from agents that corresponds to entries currently not in use. Proper interpretation of such entries requires examination of the relevant EntryStatus object. An existing instance of this object cannot be set to createRequest(2). This object may only be set to createRequest(2) when this instance is created. When this object is created, the agent may wish to create supplemental object instances with default values to complete a conceptual row in this table. Because the creation of these default objects is entirely at the option of the agent, the manager must not assume that any will be created, but may make use of any that are created. Immediately after completing the create operation, the agent must set this object to underCreation(3). When in the underCreation(3) state, an entry is allowed to exist in a possibly incomplete, possibly inconsistent state, usually to allow it to be modified in multiple PDUs. When in this state, an entry is not fully active. Entries shall exist in the underCreation(3) state until the management station is finished configuring the entry and sets this object to valid(1) or aborts, setting this object to invalid(4). If the agent determines that an entry has been in the underCreation(3) state for an abnormally long time, it may decide that the management station has crashed. If the agent makes this decision, it may set this object to invalid(4) to reclaim the entry. A prudent agent will understand that the management station may need to wait for human input and will allow for that possibility in its determination of this abnormally long period. An entry in the valid(1) state is fully configured and consistent and fully represents the configuration or operation such a row is intended to represent. For example, it could be a statistical function that is configured and active, or a filter that is available in the list of filters processed by the packet capture process. A manager is restricted to changing the state of an entry in the following ways: To: valid createRequest underCreation invalid From: valid OK NO OK OK createRequest N/A N/A N/A N/A underCreation OK NO OK OK invalid NO NO NO OK nonExistent NO OK NO OK In the table above, it is not applicable to move the state from the createRequest state to any other state because the manager will never find the variable in that state. The nonExistent state is not a value of the enumeration, rather it means that the entryStatus variable does not exist at all. An agent may allow an entryStatus variable to change state in additional ways, so long as the semantics of the states are followed. This allowance is made to ease the implementation of the agent and is made despite the fact that managers should never exercise these additional state transitions."; } identity rmonEventsV2 { base smiv2:object-identity; description "Definition point for RMON notifications."; } container RMON-MIB { config false; container etherStatsTable { smiv2:oid "1.3.6.1.2.1.16.1.1"; description "A list of Ethernet statistics entries."; list etherStatsEntry { smiv2:oid "1.3.6.1.2.1.16.1.1.1"; key "etherStatsIndex"; description "A collection of statistics kept for a particular Ethernet interface.

A repeater port must detect a collision when two or more stations are transmitting simultaneously. Thus a probe placed on a repeater port could record more collisions than a probe connected to a station on the same segment would. Probe location plays a much smaller role when considering 10BASE-T. 14.2.1.4 (10BASE-T) of IEEE standard 802.3 defines a collision as the simultaneous presence of signals on the DO and RD circuits (transmitting and receiving at the same time). A 10BASE-T station can only detect collisions when it is transmitting. Thus probes placed on a station and a repeater, should report the same number of collisions. Note also that an RMON probe inside a repeater should ideally report collisions between the repeater and one or more other hosts (transmit collisions as defined by IEEE 802.3k) plus receiver collisions observed on any coax segments to which the repeater is connected."; } leaf etherStatsPkts64Octets { smiv2:max-access "read-only"; smiv2:oid "1.3.6.1.2.1.16.1.1.1.14"; type yang:counter32; units "Packets"; description "The total number of packets (including bad packets) received that were 64 octets in length (excluding framing bits but including FCS octets)."; } leaf etherStatsPkts65to127Octets { smiv2:max-access "read-only"; smiv2:oid "1.3.6.1.2.1.16.1.1.1.15"; type yang:counter32; units "Packets"; description "The total number of packets (including bad packets) received that were between 65 and 127 octets in length inclusive (excluding framing bits but including FCS octets)."; } leaf etherStatsPkts128to255Octets { smiv2:max-access "read-only"; smiv2:oid "1.3.6.1.2.1.16.1.1.1.16"; type yang:counter32; units "Packets"; description "The total number of packets (including bad packets) received that were between 128 and 255 octets in length inclusive (excluding framing bits but including FCS octets)."; } leaf etherStatsPkts256to511Octets { smiv2:max-access "read-only"; smiv2:oid "1.3.6.1.2.1.16.1.1.1.17"; type yang:counter32; units "Packets"; description "The total number of packets (including bad packets) received that were between 256 and 511 octets in length inclusive (excluding framing bits but including FCS octets)."; } leaf etherStatsPkts512to1023Octets { smiv2:max-access "read-only"; smiv2:oid "1.3.6.1.2.1.16.1.1.1.18"; type yang:counter32; units "Packets"; description "The total number of packets (including bad packets) received that were between 512 and 1023 octets in length inclusive (excluding framing bits but including FCS octets)."; } leaf etherStatsPkts1024to1518Octets { smiv2:max-access "read-only"; smiv2:oid "1.3.6.1.2.1.16.1.1.1.19"; type yang:counter32; units "Packets"; description "The total number of packets (including bad packets) received that were between 1024 and 1518 octets in length inclusive (excluding framing bits but including FCS octets)."; } leaf etherStatsOwner { smiv2:max-access "read-write"; smiv2:oid "1.3.6.1.2.1.16.1.1.1.20"; type OwnerString; description "The entity that configured this entry and is therefore using the resources assigned to it."; } leaf etherStatsStatus { smiv2:max-access "read-write"; smiv2:oid "1.3.6.1.2.1.16.1.1.1.21"; type EntryStatus; description "The status of this etherStats entry."; } leaf etherStatsDroppedFrames { smiv2:max-access "read-only"; smiv2:oid "1.3.6.1.2.1.16.1.4.1.1"; type yang:counter32; description "The total number of frames which were received by the probe and therefore not accounted for in the *StatsDropEvents, but for which the probe chose not to count for this entry for whatever reason.
