```

**Note** : Management Data Plane Separation (MDPS) and Multiple Security Groups (MSG) are enabled in a Dual Chassis environment.

<br />

## Cause

The WebUI uses the SMO IP, and while you review information on the WebUI, queries are sent to the Security Group Resource Manager (SGRM), which is an enabled task on a specific blade.  

Because you use MDPS, the WebUI context uses the Management plane (mplane).  

Sync \& Chassis Internal Network (CIN) interfaces are not part of the Management Plane on Scalable Platforms. Therefore, if the SMO runs on Chassis 2 when the SGRM is on Chassis 1, you cannot query the SGRM through the SYNC/CIN interface to get the topology of the Security Groups because MDPS is enabled, and the SYNC interface is part of Date plane (dplane).
