| Description | The present state of this MPC ingress cache.
The states are:
doesNotExist (1) -- the state is not yet available
inactive (2) -- state exists, entry is not yet
active. For an example, if
using the Finite State Machine
Appendix I.2, then the states
Cached and query are considered
`inactive'.
active (3) -- state exists, entry is active.
For an example, if using the
Finite State Machine in Appendix I.2,
then the states resolved and refresh
are considered `active'.
negative (4) -- state exists, entry is negative,
which could mean a NAK response was
received, or entry is doing a
retry, etc. For example, if using
the Finite State Machine in Appendix
I.2, then the state `hold down' is
considered `negative'. |
