WMS Offload Details
WMS Offload instructs the Master controller to stop correlating ARM, WIPS, and WIDS state information
amongst its Local controllers, because AWMS will assume this responsibility. Figure 25 depicts how AMWS
communicates state information with Local controllers.
Figure 25 ARM/WIPS/WIDS Classification Message Workflow
State Correlation Process
1. AP-1-3-1 hears rogue device A
2. Local controller 1-3 evaluates devices and does initial classification and sends a classification request to the
AWMS
3. AWMS receives message and re-classifies the device if necessary and reflects this within AWMS GUI and via
SNMP traps, if configured
4. AWMS sends a classification message back to all Local controllers managed by Master controller 1, (1-1, 1-2,
and 1-3)
5. AWMS sends a classification message back to all additional Local controllers managed by the AMWS 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 AWMS user manually overrides the classification, then AWMS will send a re-
classification message to all applicable local controllers
