--    Cisco WRED MIB - Overview
--    
--      Cisco Weighted Random Early Detection/Drop is a method which avoids
--      traffic congestion on an output interface.  Congestion is
--      detected by computing the average output queue size against preset
--      thresholds. WRED support are on the IP fast switching and
--      IP flow switching only.  It does not apply to IP process switching.
--    
--      This MIB incorporates objects from the Cisco WRED line interfaces.
--      Its purpose is to provide Weighted Random Early Detection/Drop
--      packet configuration and packet filtering information.
--      
--      WRED are configured/enabled through the CLI command.
--      Defaults configuration values are assigned and values can be
--      modified through additional CLI commands.
