       DESCRIPTION
                      "The rptrGroupCapacity is the number of groups

                      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

               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
