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."

}
ACCESS read-only

DESCRIPTION
"The rptrOperStatus object indicates the
operational state of the repeater. 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)

DESCRIPTION
"The health text object is a text string that

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 {

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."

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."

ACCESS read-write

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.)"

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)."

DESCRIPTION
"This counter is incremented by one for each
CarrierEvent on this port in which the CollIn(X)
variable transitions to the value SQE (Ref:
9.6.6.2, IEEE 802.3 Std) while the
ActivityDuration is greater than the
LateEventThreshold. Such a CarrierEvent is
counted twice, as both a collision and as a
lateEvent.
The LateEventThreshold is greater than 480 bit
times and less than 565 bit times.
LateEventThreshold has tolerances included to
permit an implementation to build a single
threshold to serve as both the LateEventThreshold
and ValidPacketMinTime threshold.
The approximate minimum time for rollover of this
counter is 81 hours."

STATUS mandatory
DESCRIPTION
"This counter is incremented by one for each frame
received on this port that meets all of the
following conditions: a) The CollisionEvent
signal is not asserted. b) The ActivityDuration
is greater than ValidPacketMinTime. c) The
frequency (data rate) is detectably mismatched
from the local transmit frequency. The exact
degree of mismatch is vendor specific and is to be
defined by the vendor for conformance testing.
When this event occurs, other counters whose
increment conditions were satisfied may or may not
also be incremented, at the implementor's
discretion. Whether or not the repeater was able
to maintain data integrity is beyond the scope of
this standard."

rptrMonitorPortTotalErrors OBJECT-TYPE
SYNTAX Counter
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The total number of errors which have occurred on

rptrMonitorPortFCSErrors,
rptrMonitorPortAlignmentErrors,
rptrMonitorPortFrameTooLongs,
rptrMonitorPortShortEvents,
rptrMonitorPortLateEvents,
rptrMonitorPortVeryLongEvents, and
rptrMonitorPortDataRateMismatches.
This counter is redundant in the sense that it is
the summation of information already available
through other objects. However, it is included
specifically because the regular retrieval of this
object as a means of tracking the health of a port
provides a considerable optimization of network
management traffic over the otherwise necessary
retrieval of the summed counters."

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.)"

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

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."
