RMON-MIB DEFINITIONS ::= BEGIN IMPORTS MODULE-IDENTITY, OBJECT-TYPE, OBJECT-IDENTITY, NOTIFICATION-TYPE, mib-2, Counter32, Integer32, TimeTicks FROM SNMPv2-SMI TEXTUAL-CONVENTION, DisplayString FROM SNMPv2-TC MODULE-COMPLIANCE, OBJECT-GROUP, NOTIFICATION-GROUP FROM SNMPv2-CONF; -- Remote Network Monitoring MIB rmonMibModule MODULE-IDENTITY LAST-UPDATED "200005110000Z" -- 11 May, 2000 ORGANIZATION "IETF RMON MIB Working Group" CONTACT-INFO "Steve Waldbusser Phone: +1-650-948-6500 Fax: +1-650-745-0671 Email: waldbusser@nextbeacon.com" DESCRIPTION "Remote network monitoring devices, often called monitors or probes, are instruments that exist for the purpose of managing a network. This MIB defines objects for managing remote network monitoring devices." REVISION "200005110000Z" -- 11 May, 2000 DESCRIPTION "Reformatted into SMIv2 format. This version published as RFC 2819." REVISION "199502010000Z" -- 1 Feb, 1995 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 "199111010000Z" -- 1 Nov, 1991 DESCRIPTION "The original version of this MIB, published as RFC1271." ::= { rmonConformance 8 } rmon OBJECT IDENTIFIER ::= { mib-2 16 } -- textual conventions OwnerString ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "This data type is used to model an administratively assigned name of the owner of a resource. Implementations must accept values composed of well-formed NVT ASCII sequences. In addition, implementations should accept values composed of well-formed UTF-8 sequences. It is suggested that this name contain one or more of the following: IP address, management station name, network manager's name, location, or phone number. In some cases the agent itself will be the owner of an entry. In these cases, this string shall be set to a string starting with 'monitor'. SNMP access control is articulated entirely in terms of the contents of MIB views; access to a particular SNMP object instance depends only upon its presence or absence in a particular MIB view and never upon its value or the value of related object instances. Thus, objects of this type afford resolution of resource contention only among cooperating managers; they realize no access control function with respect to uncooperative parties." SYNTAX OCTET STRING (SIZE (0..127)) EntryStatus ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The status of a table entry. 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."

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." ::= { etherStatsEntry 13 } etherStatsPkts64Octets OBJECT-TYPE SYNTAX Counter32 UNITS "Packets" MAX-ACCESS read-only STATUS current DESCRIPTION "The total number of packets (including bad packets) received that were 64 octets in length (excluding framing bits but including FCS octets)." ::= { etherStatsEntry 14 } etherStatsPkts65to127Octets OBJECT-TYPE SYNTAX Counter32 UNITS "Packets" MAX-ACCESS read-only STATUS current 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)." ::= { etherStatsEntry 15 } etherStatsPkts128to255Octets OBJECT-TYPE SYNTAX Counter32 UNITS "Packets" MAX-ACCESS read-only STATUS current 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)." ::= { etherStatsEntry 16 } etherStatsPkts256to511Octets OBJECT-TYPE SYNTAX Counter32 UNITS "Packets" MAX-ACCESS read-only STATUS current 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)." ::= { etherStatsEntry 17 } etherStatsPkts512to1023Octets OBJECT-TYPE SYNTAX Counter32 UNITS "Packets" MAX-ACCESS read-only STATUS current 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)." ::= { etherStatsEntry 18 } etherStatsPkts1024to1518Octets OBJECT-TYPE SYNTAX Counter32 UNITS "Packets" MAX-ACCESS read-only STATUS current 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)." ::= { etherStatsEntry 19 } etherStatsOwner OBJECT-TYPE SYNTAX OwnerString MAX-ACCESS read-create STATUS current DESCRIPTION "The entity that configured this entry and is therefore using the resources assigned to it." ::= { etherStatsEntry 20 } etherStatsStatus OBJECT-TYPE SYNTAX EntryStatus MAX-ACCESS read-create STATUS current DESCRIPTION "The status of this etherStats entry." ::= { etherStatsEntry 21 } -- The History Control Group -- Implementation of the History Control group is optional. -- Consult the MODULE-COMPLIANCE macro for the authoritative -- conformance information for this MIB. -- -- The history control group controls the periodic statistical -- sampling of data from various types of networks.

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." ::= { etherHistoryEntry 14 } etherHistoryUtilization OBJECT-TYPE SYNTAX Integer32 (0..10000) MAX-ACCESS read-only STATUS current DESCRIPTION "The best estimate of the mean physical layer network utilization on this interface during this sampling interval, in hundredths of a percent." ::= { etherHistoryEntry 15 } -- The Alarm Group -- Implementation of the Alarm group is optional.

If the -- monitoring device finds itself short of resources, it may -- delete entries as needed.

As this order, and thus -- the index, is among those entries currently in the table, -- the index for a particular entry may change if an -- (earlier) entry is deleted. Thus the association between -- hostTimeCreationOrder and hostTimeEntry may be broken at -- any time. -- The hostTimeTable has two important uses.

This allows very -- efficient packing of variables into SNMP PDU's and allows -- a table transfer to have multiple packets outstanding. -- These benefits increase transfer rates tremendously. -- The second use of the hostTimeTable is the efficient discovery -- by the management station of new entries added to the table. -- After the management station has downloaded the entire table, -- it knows that new entries will be added immediately after the -- end of the current table. It can thus detect new entries there -- and retrieve them easily. -- Because the association between hostTimeCreationOrder and -- hostTimeEntry may be broken at any time, the management -- station must monitor the related hostControlLastDeleteTime -- object. When the management station thus detects a deletion, -- it must assume that any such associations have been broken, -- and invalidate any it has stored locally. This includes -- restarting any download of the hostTimeTable that may have been -- in progress, as well as rediscovering the end of the -- hostTimeTable so that it may detect new entries. If the -- management station does not detect the broken association, -- it may continue to refer to a particular host by its -- creationOrder while unwittingly retrieving the data associated -- with another host entirely.
