-- Name:          H3C Layer 4 Redirection MIB
-- 
-- Description: 
--  
-- This MIB is used to configure the redirection of network traffic to a
-- network appliance.  It is to be used for switches that are Layer 4 
-- capable.  It is divided into 3 tables and 4 scalar objects:  
-- the Cache table, the IP Exclusion Table, the Redirect VLAN table, 
-- the Information String object, the Free Cache Entries object, 
-- the Free IP Exclusion Entries object, and the Free Redirect VLAN 
-- Entries object.
-- 
-- The Cache table is responsible for storing the information
-- about each cache to which network traffic is potentially being
-- redirected.  This table includes the cache IP address, the status
-- of redirection, the cache port, the cache VLAN, and TCP port
-- information. 
-- 
-- The IP Exclusion table is responsible for storing the IP information 
-- on any IP addresses/subnetworks that are NOT allowed to be redirected.
-- 
-- The Redirect VLAN table is responsible for storing the VLAN ID of 
-- the packet which need to be redirected to the Web cache.
--
-- The Information String object is responsible for storing a string.  This 
-- string will contain information pertaining to configuring Layer 4
-- Redirection (success or failure). 
-- 
-- The Free Cache Entries object is responsible for storing the number
-- of entries that may still be added to the Cache Table.
-- 
-- The Free IP Exclusion Entries object is responsible for storing the 
-- number of entries that may still be added to the IP Exclusion Table. 
--
-- The Free Redirect VLAN Entries object is responsible for storing the 
-- number of entries that may still be added to the Redirect VLAN Table. 
--
-- History V2.0
--
-- V1.00     4/23/04     Created.
-- V2.0 2004-10-12 updated by gaolong
--      Add hh3cL4Redirect MODULE-IDENTITY clause.
--      Change ACCESS clause to MAX-ACCESS
--      Change value of STATUS from mandatory to current
