    DESCRIPTION
        "This MIB module defines objects required for managing
        Resilient Ethernet Protocol (REP).

        Resilient Ethernet Protocol (REP) is a Cisco proprietary 
        protocol that provides an alternative to Spanning Tree 
        Protocol (STP) to control network loops, handle link 
        failures and improve convergence time. 

        REP controls a group of ports connected in a segment; 
        ensures that the segment does not create any bridging loops, 
        and responds to link failures within the segment. 

        The following diagram depicts a REP segment:

        [Sw E1]E---NE[Sw 1]NE---NE[Sw 2]NE.........
                                                  .
                                                  .
        [Sw E2]E---NE[Sw N]NE---NE[Sw N-1]NE.......

        Sw : Switch.
        E  : Edge port.
        NE : Non-Edge port.  
        E1/E2: Edge switches.  E1 and E2 can either be same or 
        different switches.

        A REP segment is a chain of ports connected to each other 
        and configured with a segment identifier.  Each segment 
        consists of standard (non-edge) segment ports and up to
        two edge ports.  A device can have only two ports that 
        belong to the same segment, and each segment port can have
        only one external neighbor. 

        One edge port in a REP segment acts as the primary edge
        port; the other as the secondary edge port.  It is the primary 
        edge port that always participates in VLAN load balancing in 
        a REP segment.  REP VLAN load balancing is achieved by blocking
        some VLANs at a configured alternate port and all other VLANs at
        an edge port.  The execution (preemption) of VLAN load balancing
        is triggered by manually enforcing it or after a pre-defined
        delay, after the REP segment is complete.

        When segment is completed, all ports will be in open state
        except one port that can be in alternate state that is used for
        VLAN load balancing as explained above."

        'notEdge'     - non-edge Port.

        'edge'        - edge port for the segment.

        'edgePrimary' - primary edge port for the segment."

        identifier for the REP segment."
    SYNTAX          Unsigned32

RepSegmentList ::= TEXTUAL-CONVENTION
    STATUS          current
    DESCRIPTION
        "This TC describes an object that indicates the list
        of REP segments.  Each octet within this value specifies
        a set of eight segments.  The first octet represents the
        first 8 segments of the range of segments specified by 
        the object, the second octet represents the next 8 segments
        etc.  

        Within each octet, the most significant bit represents
        the lowest numbered segment, and the least significant bit
        represents the highest numbered segment.  If that bit has 
        a value of '1' then that segment is included in the set of 
        segments; the segment is not included if its bit has a value
        of '0'.

        NMS may omit any zero-valued octets from the end of this string
        in order to reduce SetPDU size, and the agent may also omit
        zero-valued trailing octets, to reduce the size of GetResponse
        PDUs.

        The maximum length of the object that uses this TC is calculated
        to be the ceiling whole number of 
        ((crepMaxSegmentId - crepMinSegmentId + 1) / 8).  
        Any octets beyond this length in the SetPDU should be ignored."
