DESCRIPTION
"This object can be set by a management station

The purpose of this object is to provide a means
for network management software to inform an end
station that it is using a duplicate station
address. Setting this object does not affect the
current state of the link; the end station will
not be informed of the duplicate address until it
retrains for some reason. Note that regardless
of its station address, the end station will not
be able to train successfully until the network
management software has set this object back to
'false'. Although this object exists on
cascade ports, it does not perform any function
since this repeater is the initiator of training

DESCRIPTION
"A vgRptrHealth trap conveys information related
to the operational state of a repeater. This trap
is sent when the value of an instance of
vgRptrInfoOperStatus changes. The vgRptrHealth
trap is not sent as a result of powering up a
repeater.
The vgRptrHealth trap must contain the instance of
the vgRptrInfoOperStatus object associated with
the affected repeater.
The agent must throttle the generation of
consecutive vgRptrHealth 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.)"

DESCRIPTION
"A vgRptrResetEvent trap conveys information

This trap is sent on completion of a repeater
reset action. A repeater reset action is defined
as a transition to its initial state as specified
in clause 12 [IEEE Std 802.12] when triggered by
a management command.
The vgRptrResetEvent trap is not sent when the
agent restarts and sends an SNMP coldStart or
warmStart trap.
The vgRptrResetEvent trap must contain the
instance of the vgRptrInfoOperStatus object
associated with the affected repeater.
The agent must throttle the generation of
consecutive vgRptrResetEvent 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.)"

6. Security Considerations
Certain management information defined in this MIB may be considered
sensitive in some network environments. Therefore, authentication of
received SNMP requests and controlled access to management
information should be employed in such environments. The method for
this authentication is a function of the SNMP Administrative
Framework, and has not been expanded by this MIB.
Several objects in the vgRptrConfigGroup allow write access. Setting
these objects can have a serious effect on the operation of the
network, including modifying the framing type of the network,
resetting the repeater, enabling and disabling individual ports, and
modifying the allowed capabilities of end stations attached to each
port. It is recommended that implementers seriously consider whether
set operations should be allowed without providing, at a minimum,
authentication of request origin.
One particular object in this MIB, vgRptrPortAllowedTrainType, is
considered significant for providing operational security in an
802.12 network. It is recommended that network administrators
configure this object to the 'allowEndNodesOnly' value on all ports
except ports which the administrator knows are attached to cascaded
repeaters or devices which require promiscuous receive capability
(bridges, switches, RMON probes, etc.). This will prevent
unauthorized users from extending the network (by attaching cascaded
repeaters or bridges) without the administrator's knowledge, and will
prevent unauthorized end nodes from listening promiscuously to
network traffic.
