Ifindex changed on the flow source





Article describing how are reflected changes of ifindex on the Flowmon side for 3rd party flow sources.


Product: Flowmon Collector

Version: Any

Platform: Any

Question/Problem Description:

Are required any steps if the ifindex number changes on the flow source? How these changes are reflected in Flowmon Monitoring Center?

Steps to Reproduce:  
Error Message:  
Defect Number:  
Enhancement Number:  
Cause: For 3rd party flow sources, the ifindex numbers may change dynamically (e.g. after reboot or due to a bug).
Resolution: Ifindex is taken to the GUI from SNMP and updated every hour. Is recommended to avoid these changes for the flow source. if the ifindex is changed for the profiled interface, this channel is deleted and the interface with a new ifindex is detected.
