Current Alias Table state.
notStarted(1) indicates the agent has not
completed any required start up routines and
therefore the ctAliasTable and ctAliasControlTable
are not currently valid.
ready(2) indicates that the agent has completed
all initialization procedures and that the alias
MIB is running properly.
full(3) indicates that due to memory restrictions
on the agent, the ctaliasTable has reached the
maximum number of entries possible.
NOTE: If an agent is using a circular queue design,
then the state of full(3) will never be set.
