This table extends the 'casConfigTable' from
CISCO-AAA-SERVER-MIB to provide configuration
flexibility.
An entry cannot be created until at least one of the
following objects/object-set are instantiated :
- cAAAServerAddrType and cAAAServerAddr set
Or
- casAddress of casConfigTable
If both 'casAddress' and 'cAAAServerAddr'(along with
'cAAAServerAddrType') are set during the row creation,
the values need to be consistent. Else it results in
an error.
