                      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.

                      counters defined in this document nor does it
                      affect the vgRptrPortAdminStatus parameters.
                      Included in this action is the execution of a
                      disruptive Self-Test with the following
                      characteristics:

                          1) The nature of the tests is not specified.
                          2) The test resets the repeater but without
                             affecting configurable management
                             information about the repeater.
                          3) Packets received during the test may or
                             may not be transferred.
                          4) The test does not interfere with
                             management functions.

                      After performing this self-test, the agent will
                      update the repeater health information (including
                      vgRptrInfoOperStatus), and send a

                      The agent must reject a SET of this object if the
                      value includes no capabilities that are
                      supported by this port's hardware, as defined by
                      the values of the corresponding instances of
                      vgRptrPortSupportedPromiscMode and
                      vgRptrPortSupportedCascadeMode.

                      Note that vgRptrPortSupportPromiscMode and
                      vgRptrPortSupportedCascadeMode represent what the
                      port hardware is capable of supporting.
                      vgRptrPortAllowedTrainType is used for setting an
                      administrative policy for a port.  The actual set
                      of training configurations that will be allowed
                      to succeed on a port is the intersection of what
                      the hardware will support and what is
                      administratively allowed.  The above requirement
                      on what values may be set to this object says that
                      the intersection of what is supported and what is
                      allowed must be non-empty.  In other words, it
                      must not result in a situation in which nothing
                      would be allowed to train on that port.  However,
                      a value can be set to this object as long as the
                      combination of this object and what is supported
                      by the hardware would still leave at least one
                      configuration that could successfully train on the
                      port.
