CTRON-ALIAS-MIB Table View

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.
