WMS Offload Details
WMS Offload instructs the Master controller to stop correlating ARM, WIPS, and WIDS state information
amongst its Local controllers, because AMP will assume this responsibility. Figure 24 depicts how Dell
PowerConnect W-AirWave communicates state information with Local controllers.
Figure 24 ARM/WIPS/WIDS Classification Message Workflow
State Correlation Process
1. Dell PowerConnect W-Series AP hears rogue device A
2. Local controller 1-3 evaluates devices and does initial classification and sends a classification request to the
AMP
3. AMP receives message and re-classifies the device if necessary and reflects this within AMP GUI and via
SNMP traps, if configured
4. AMP sends a classification message back to all Local controllers managed by Master controller 1, (1-1, 1-2, and
1-3)
5. AMP sends a classification message back to all additional Local controllers managed by the Dell
PowerConnect W-AirWave server. In this example all Local controllers under Master controller 2, (2-1, 2-2,
and 2-3) would receive the classification messages.
6. If an administrative AMP user manually overrides the classification, then AMP will send a re-classification
message to all applicable local controllers
