We use MLM's with Netview version 5.1 (testing 5.1.1 now). You an set
up distribution through the collection facility. Check out the netmon
man pages and the MLM documentation specifics. The -C flag to netmon
allows you to set a collection prefix to assign nodes in the collection
to the MLM's. The collection name must be the MLM Prefix specified by
the -C flag prepended to the MLM name. You can do a "failover" to
another MLM by changing the collection rules of the backup and primary
MLM collections in response to the Mid-Level Manager down trap.
