Modifying Switch Components in a Stack
Typically, a device's interfaces remain fairly stable and unchanging. However, devices that reside in a chassis or those that can be stacked share management between separate boards or stacked units. When boards or units are added, removed, or repositioned within the chassis or stack, it is necessary to have FortiNAC re-read the device to learn of the changes and display an accurate representation in the Ports tab in Topology View. See Resync interfaces.
Note: If the indexing has changed and FortiNAC needs to remodel the interfaces, FortiNAC will delete and recreate new port models to represent the re-indexed switch interfaces. This will affect manual port grouping done for the interface models.
