+    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."

+    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."
