    --  Abstract
 
    --  This memo defines bridging management objects that are not defined
    --  in the IETF RFC:1286 - Definitions of Managed Objects for Bridges,
    --  but are supported by Cabletron bridges.
 
 
    --  Structure of MIB
 
    --  Objects, in this MIB, are arranged into groups.  Each group is organized
    --  as a set of related objects and is described below.
 
    --  The ctBridgeBase Group
 
    --  This group contains objects that are common to all types of bridges.
    --  No current objects are defined in this group.
 

    --  The ctBridgeStp Group
 
    --  This group contains the objects that are specific to the Spanning
    --  Tree Protocol.  If the bridge does not support the Spanning Tree
    --  Protocol, this group will not be implemented.  This group is
    --  applicable to any transparent only, source route only, or SRT bridge
    --  which implements the Spanning Tree Protocol.
 
    --  The ctBridgeSr Group
 
    --  This group contains the objects that are specific to source route
    --  bridging.  If source routing is not supported this group will not
    --  be implemented.  This group is applicable to source route only, and
    --  SRT bridges.
 
    --  The ctBridgeTp Group
 
    --  This group contains objects that are specific to transparent
    --  bridging.  If transparent bridging is not supported this group
    --  will not be implemented.  This group is applicable to transparent
    --  only, and SRT bridges.

    --  The ctBridgeSdbEnet Group
 
    --  This group contains objects that are specific to transparent
    --  Ethernet/802.3 bridging using Cabletron's proprietary special
    --  filter database.  If Ethernet/802.3 transparent bridging is not
    --  supported this group will not be implemented.  This group is
    --  applicable to transparent only, and SRT bridges that support
    --  Ethernet/802.3 networks.
 
    --  The ctBridgeSdbTr Group
 
    --  This group contains objects that are specific to transparent
    --  Token Ring bridging using Cabletron's proprietary special filter
    --  database.  If Token Ring transparent bridging is not supported
    --  this group will not be implemented.  This group is applicable
    --  to transparent only, and SRT bridges that support Token Ring
    --  networks.

    --  The ctBridgeTransTrEnet Group

    --  This group contains objects that are specific to the translation
    --  of packets between Token Ring and Ethernet for transparent or
    --  source route bridging.  If Token Ring to Ethernet bridging is not
    --  supported this group will not be implemented. 

    --  The ctBridgeExtendedControl Group

    --  This group contains objects that control extended functionality.
    --  This includes turning off chassis managment functionality.
    --  This group is only supported on those devices that support
    --  extended control functionality.

    --  The ctBridgeLoadShare Group

    --  This group contains objects that control load sharing.
    --  This concept is also known as Multi-Link Spanning Tree.  
    --  This group is optional.
