rptrGroupCapacity OBJECT-TYPE SYNTAX INTEGER (1..1024) ACCESS read-only STATUS mandatory DESCRIPTION "The rptrGroupCapacity is the number of groups that can be contained within the repeater. Within each managed repeater, the groups are uniquely numbered in the range from 1 to rptrGroupCapacity.
Some groups may not be present in the repeater, in which case the actual number of groups present will be less than rptrGroupCapacity. The number of groups present will never be greater than rptrGroupCapacity.
Note: In practice, this will generally be the number of field-replaceable units (i.e., modules, cards, or boards) that can fit in the physical repeater enclosure, and the group numbers will correspond to numbers marked on the physical enclosure."

The rptrHealthText object may be consulted for more specific information about the state of the repeater's health.
In the case of multiple kinds of failures (e.g., repeater failure and port failure), the value of this attribute shall reflect the highest priority failure in the following order, listed highest priority first:
rptrFailure(3) groupFailure(4) portFailure(5) generalFailure(6)." REFERENCE "Reference IEEE 802.3 Rptr Mgt, 19.2.3.2, aRepeaterHealthState." ::= { rptrRptrInfo 2 }
rptrHealthText OBJECT-TYPE SYNTAX DisplayString (SIZE (0..255)) ACCESS read-only STATUS mandatory DESCRIPTION "The health text object is a text string that provides information relevant to the operational state of the repeater. Agents may use this string to provide detailed information on current failures, including how they were detected, and/or instructions for problem resolution. The contents are agent-specific."

rptrReset OBJECT-TYPE SYNTAX INTEGER { noReset(1), reset(2) } ACCESS read-write STATUS mandatory DESCRIPTION "Setting this object to reset(2) causes a transition to the START state of Fig 9-2 in section 9 [IEEE 802.3 Std].
Setting this object to noReset(1) has no effect. The agent will always return the value noReset(1) when this object is read.
After receiving a request to set this variable to reset(2), the agent is allowed to delay the reset for a short period. For example, the implementor may choose to delay the reset long enough to allow the SNMP response to be transmitted. In any event, the SNMP response must be transmitted.
This action does not reset the management counters defined in this document nor does it affect the portAdminStatus parameters. Included in this action is the execution of a disruptive Self-Test with the following characteristics: a) The nature of the tests is not specified. b) The test resets the repeater but without affecting management information about the repeater. c) The test does not inject packets onto any segment. d) Packets received during the test may or may not be transferred. e) The test does not interfere with management functions.
After performing this self-test, the agent will update the repeater health information (including rptrOperStatus and rptrHealthText), and send a rptrHealth trap." REFERENCE "Reference IEEE 802.3 Rptr Mgt, 19.2.3.3, acResetRepeater." ::= { rptrRptrInfo 4 }
rptrNonDisruptTest OBJECT-TYPE SYNTAX INTEGER { noSelfTest(1),
selfTest(2) } ACCESS read-write STATUS mandatory DESCRIPTION "Setting this object to selfTest(2) causes the repeater to perform a agent-specific, non- disruptive self-test that has the following characteristics: a) The nature of the tests is not specified. b) The test does not change the state of the repeater or management information about the repeater. c) The test does not inject packets onto any segment. d) The test does not prevent the relay of any packets. e) The test does not interfere with management functions.
After performing this test, the agent will update the repeater health information (including rptrOperStatus and rptrHealthText) and send a rptrHealth trap.
Note that this definition allows returning an 'okay' result after doing a trivial test.
Setting this object to noSelfTest(1) has no effect. The agent will always return the value noSelfTest(1) when this object is read." REFERENCE "Reference IEEE 802.3 Rptr Mgt, 19.2.3.3, acExecuteNonDisruptiveSelfTest." ::= { rptrRptrInfo 5 }

This value may be allocated within the SMI enterprises subtree (1.3.6.1.4.1) and provides a straight-forward and unambiguous means for determining what kind of group is being managed.
For example, this object could take the value 1.3.6.1.4.1.4242.1.2.14 if vendor 'Flintstones, Inc.' was assigned the subtree 1.3.6.1.4.1.4242, and had assigned the identifier 1.3.6.1.4.1.4242.1.2.14 to its 'Wilma Flintstone 6-Port FOIRL Plug-in Module.'" ::= { rptrGroupEntry 3 }
rptrGroupOperStatus OBJECT-TYPE SYNTAX INTEGER { other(1), operational(2), malfunctioning(3), notPresent(4),
underTest(5), resetInProgress(6) } ACCESS read-only STATUS mandatory DESCRIPTION "An object that indicates the operational status of the group.
A status of notPresent(4) indicates that the group is temporarily or permanently physically and/or logically not a part of the repeater. It is an implementation-specific matter as to whether the agent effectively removes notPresent entries from the table.
A status of operational(2) indicates that the group is functioning, and a status of malfunctioning(3) indicates that the group is malfunctioning in some way." ::= { rptrGroupEntry 4 }
rptrGroupLastOperStatusChange OBJECT-TYPE SYNTAX TimeTicks ACCESS read-only STATUS mandatory DESCRIPTION "An object that contains the value of sysUpTime at the time that the value of the rptrGroupOperStatus object for this group last changed.

Valid range is 1-1024. Within each group, the ports are uniquely numbered in the range from 1 to rptrGroupPortCapacity.
Note: In practice, this will generally be the

rptrPortAdminStatus OBJECT-TYPE SYNTAX INTEGER { enabled(1), disabled(2) } ACCESS read-write STATUS mandatory DESCRIPTION "Setting this object to disabled(2) disables the port. A disabled port neither transmits nor receives. Once disabled, a port must be explicitly enabled to restore operation. A port which is disabled when power is lost or when a reset is exerted shall remain disabled when normal operation resumes.
The admin status takes precedence over auto- partition and functionally operates between the auto-partition mechanism and the AUI/PMA.
Setting this object to enabled(1) enables the port and exerts a BEGIN on the port's auto-partition state machine.
(In effect, when a port is disabled, the value of rptrPortAutoPartitionState for that port is frozen until the port is next enabled. When the port
becomes enabled, the rptrPortAutoPartitionState becomes notAutoPartitioned(1), regardless of its pre-disabling state.)" REFERENCE "Reference IEEE 802.3 Rptr Mgt, 19.2.6.2, aPortAdminState and 19.2.6.3, acPortAdminControl." ::= { rptrPortEntry 3 }
rptrPortAutoPartitionState OBJECT-TYPE SYNTAX INTEGER { notAutoPartitioned(1), autoPartitioned(2) } ACCESS read-only STATUS mandatory DESCRIPTION "The autoPartitionState flag indicates whether the port is currently partitioned by the repeater's auto-partition protection.

rptrPortOperStatus OBJECT-TYPE SYNTAX INTEGER { operational(1), notOperational(2), notPresent(3) } ACCESS read-only STATUS mandatory DESCRIPTION "This object indicates the port's operational status. The notPresent(3) status indicates the port is physically removed (note this may or may not be possible depending on the type of port.) The operational(1) status indicates that the port is enabled (see rptrPortAdminStatus) and working, even though it might be auto-partitioned (see rptrPortAutoPartitionState).
If this object has the value operational(1) and
rptrPortAdminStatus is set to disabled(2), it is expected that this object's value will soon change to notOperational(2)." ::= { rptrPortEntry 5 }

-- Traps are defined using the conventions in RFC 1215 [6].
rptrHealth TRAP-TYPE ENTERPRISE snmpDot3RptrMgt VARIABLES { rptrOperStatus } DESCRIPTION "The rptrHealth trap conveys information related to the operational status of the repeater. This trap is sent either when the value of rptrOperStatus changes, or upon completion of a non-disruptive test.
The rptrHealth trap must contain the rptrOperStatus object. The agent may optionally include the rptrHealthText object in the varBind list. See the rptrOperStatus and rptrHealthText objects for descriptions of the information that is sent.
The agent must throttle the generation of consecutive rptrHealth traps so that there is at least a five-second gap between traps of this type. When traps are throttled, they are dropped, not queued for sending at a future time. (Note that 'generating' a trap means sending to all configured recipients.)" REFERENCE "Reference IEEE 802.3 Rptr Mgt, 19.2.3.4, hubHealth notification." ::= 1
rptrGroupChange TRAP-TYPE ENTERPRISE snmpDot3RptrMgt VARIABLES { rptrGroupIndex } DESCRIPTION "This trap is sent when a change occurs in the group structure of a repeater. This occurs only when a group is logically or physically removed from or added to a repeater. The varBind list contains the identifier of the group that was removed or added.
The agent must throttle the generation of consecutive rptrGroupChange traps for the same group so that there is at least a five-second gap between traps of this type. When traps are throttled, they are dropped, not queued for sending at a future time. (Note that 'generating' a trap means sending to all configured recipients.)" REFERENCE "Reference IEEE 802.3 Rptr Mgt, 19.2.3.4, groupMapChange notification." ::= 2
rptrResetEvent TRAP-TYPE ENTERPRISE snmpDot3RptrMgt VARIABLES { rptrOperStatus } DESCRIPTION "The rptrResetEvent trap conveys information related to the operational status of the repeater. This trap is sent on completion of a repeater reset action. A repeater reset action is defined as an a transition to the START state of Fig 9-2 in section 9 [IEEE 802.3 Std], when triggered by a management command (e.g., an SNMP Set on the rptrReset object).
The agent must throttle the generation of consecutive rptrResetEvent traps so that there is at least a five-second gap between traps of this type. When traps are throttled, they are dropped, not queued for sending at a future time. (Note that 'generating' a trap means sending to all configured recipients.)
The rptrResetEvent trap is not sent when the agent restarts and sends an SNMP coldStart or warmStart trap. However, it is recommended that a repeater agent send the rptrOperStatus object as an optional object with its coldStart and warmStart trap PDUs.
The rptrOperStatus object must be included in the varbind list sent with this trap. The agent may optionally include the rptrHealthText object as well." REFERENCE "Reference IEEE 802.3 Rptr Mgt, 19.2.3.4, hubReset notification." ::= 3
