I came to notice that there is no option available in RA to generate a TRAP where there are NO FLOWS from device for any specific time period. Whereas RA provide a feature to generate a TRAP if defined flows value is breached.
TRAP for any interface which has more than 1000 flows/min ---- Available
TRAP for any interface which does not have flows from last 1hr/2days ---- Not Available
By adding this feature it will proactively help a Network Engineer to detect problems in network.
Can anybody knows how to achieve this.
