Can be used to solve the multiple-manager problem.
Before performing any SETs, the manager reads this
value. As a VAR-BIND of the only/last SET PDU,
this value is written with that value read. If
some other manager had made changes, this value
would have incremented, and the SET to it will
fail.
Note that this only guards against other managers
that use this semaphore. Changes made without
using this value will NOT be protected against.
For this reason, it is suggested that
ccCfgHistChangeCount also be SET - though that is
not a perfectly fail-safe semaphore, it will in
most cases protect even against this latter case.
