ctAliasMarkInactive
1.3.6.1.4.1.52.4.1.3.7.1.1.2.1.2
This object provides the control to mark this entry
to inactive.
When an entry is created by the agent, this is set to
false(2). A network management application can set this
value to true(1), indicating that the entry is no longer
needed. Once this object has been set to true(1), it
cannot be set to false(2).
If the alias is detected again by the agent, the agent
may create a new entry for the Alias.
When an agent needs to free up resources, it may choose
to delete those entries marked inactive.
