    DESCRIPTION
        "This MIB module defines a portion of the MIB tree
         under the Enterasys enterprise OID. This branch 
         defines Enterasys Networks' proprietary Node Alias
         feature.

         This MIB defines objects which can be used to discover 
         end systems per port, and to map end system addresses
         to the layer 2 address of the port."

-- Alias Table

ctAliasTable OBJECT-TYPE
    SYNTAX  SEQUENCE OF CtAliasEntry
    MAX-ACCESS   not-accessible
    STATUS  current
    DESCRIPTION
        "The ctAliasTable contains information about the aliases
         known by the agent.  This table is indexed using a unique
         and arbitrary ID and a TimeFilter to allow a management
         station to learn all alias entries that have been modified
         since time X.  This table is NOT designed to do a single
         GET.  This Table is designed for MIB Walks only.

         This table contains objects that map upper-layer 
         network services and entities to the physical location 
         of the associated port, and the MAC address of the
         associated end-system (node).

         All entries in this table are deleted when sysUpTime
         is reset to zero.

         This table allows for a time filtered view.  It is useful 
         for determining what has been modified in the Alias Table 
         since a specified time.

         If a management station reads the ctAliasTable
         of an entity at time X, subsequent updates can be 
         realized by performing get-next requests of this
         table to determine which entries have been modified 
         since time X. Then the management station can use
         GET requests to retrieve only the records of interest
         from the Alias table. 

         There is a delay between retrieving the Alias Reference 
         values from this table, and a GET request to retrieve a 
         modified row from the Alias table. The management 
         station should be prepared for two possibilities:
         1) the GET request may fail if the Alias table entry 
         has been deleted during the delay, and 2) the 
         entry may have been modified during the delay, so the
         modification time of the retrieved entry may differ from 
         the modification time of the Delta entry.

         If the entry in the Alias Control table identified by 
         ctAliasID is marked inactive by management request, and 
         subsequently deleted to free resources, all corresponding 
         entries in this table are also deleted.

         If the agent needs to free resources, it can delete
         entries from this table. It SHOULD first remove those
         which have been marked inactive in the ctAliasControlTable, 
         then it SHOULD remove those entries with the oldest 
         modification times."

         The ifIndex is an 'external value' that identifies a

         This object can be used to identify the physical
         location of the interface in the ifTable [RFC2863].  

         The possibility of ifIndex value re-assignment must be
         accommodated by a management application whenever the 
         value of sysUpTime is reset to zero.

         Since ifIndex values in different 'naming scopes' are 
         not related to one another, the interface to physical 
         component associations are relative to the same
         logical entity within the agent. For more discussion
