Network Performance Monitor

Cause

SolarWinds polls standard IF-MIB interfaces for F5 devices. F5 devices use IF-MIB and also F5 enterprise MIBs for their interfaces. BigIP systems use IF-MIB for standard Linux data only and you must use F5 enterprise MIBs for interfaces that are specific to BigIP system. This feature is about adding support for F5 specific interfaces that are polled from F5 enterprise MIB (F5-BIGIP-SYSTEM-MIB).

Resolution

SolarWinds polls the interface data from both IF-MIB and F5 enterprise MIBs, therefore you will see the duplicated interfaces in the List Resource.

The following is the interface description from IF-MIB and F5 enterprise MIB:
