21. A system, comprising:
an enterprise management system residing on a network device for managing a wireless network, the enterprise management system including an offline management policy;
a wireless agent residing on a second network device, the enterprise management system sending the offline management policy to the wireless agent when the second network device is connected to the network, wherein the wireless agent manages the second network device using the offline management policy when the second network device is not connected to the wireless network.
22. The system of claim 21, wherein the offline management policy includes a triggering parameter and a management action and the wireless agent compares a collected parameter to the trigger parameter.
23. The system of claim 22, wherein the wireless agent initiates the management action when the collected parameter satisfies the trigger parameter.
24. The system of claim 21, wherein the network device is one of a network appliance and a network server.

26. The system of claim 21, wherein the enterprise management system send the offline management policy to the wireless agent via one of an access point and a wireless switch.
27. The system of claim 21, wherein the offline management policy corresponds to an online management policy stored in the enterprise management system.
28. The system of claim 21, wherein the wireless agent sends a message to the enterprise management system indicating that the offline management policy was triggered, the message being sent when the second network device reconnects to the network.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An apparatus for applying and releasing a clutch piston in a clutch cylinder, the apparatus comprising:
a fill oil chamber having first and second portions separated by a fill piston, said first portion being a fluid communication with the clutch cylinder through a first passage, and said second portion being in fluid communication with a second passage;
a third passage in fluid communication with the first passage; and
a fill control valve operative to alternately communicate the second passage to a transmission line pressure passage or an exhaust passage, and further operative to alternately communicate the third passage to a controllable source of pressurized oil having a signal pressure or to close the third passage.
2. The apparatus of claim 1, wherein said fill control valve comprises a double spool valve biased by a spring.
3. The apparatus of claim 1, wherein said third passage is connected to the first passage through an orifice.
4. The apparatus of claim 1, wherein said fill oil chamber is positioned below the lowest sump level of a transmission in which the apparatus is positioned.
5. The apparatus of claim 1, further comprising a snubber formed in the fill oil chamber to cushion movement of the clutch piston when applying the clutch piston.
6. The apparatus of claim 1, wherein the apparatus is operative to switch between application of line pressure or signal pressure to the clutch piston to cause a rapid, controlled application and release of the clutch piston.
7. A method for applying and releasing a clutch piston in a clutch cylinder, the method comprising:
providing a source of transmission line pressure;
providing a controllable source of pressurized oil having a signal pressure; and
alternately communicating the clutch cylinder with the source of transmission line pressure and the controllable source of pressurized oil to control application and release of the clutch piston.
8. The method of claim 7, wherein said step of alternately communicating comprises, when applying the clutch piston, communicating said source of transmission line pressure with the clutch cylinder via a fill piston until the fill piston bottoms out, and then communicating said controllable source of pressurized oil to the clutch cylinder to cause a smooth, controlled clutch application.
9. The method of claim 8, further comprising controlling said controllable source of pressurized oil to control the normal force on a clutch pack applied by the clutch piston during applying, holding and releasing of a clutch.
10. The method of claim 9, further comprising reducing pressure of said controllable source of pressurized oil to enable a spool valve spring to move a spool valve to exhaust pressure from the clutch cylinder and allow a clutch return spring to move oil from the clutch cylinder to a fill oil chamber to be available for the next apply stroke.
11. A method for applying and releasing a clutch piston in a clutch cylinder, the method comprising:
providing a source of transmission line pressure;
providing a controllable source of pressurized oil having a signal pressure;
communicating said source of transmission line pressure with the clutch cylinder via a fill piston until the fill piston bottoms out;
thereafter communicating said controllable source of pressurized oil to the clutch cylinder to cause a smooth, controlled clutch application; and
