i'm using netflow analyzer to monitor one cisco router with three physical interface and 4 virtual interfaces. configuration on all interfaces is the same and yet one of the physical interfaces is not showing at all.
interface 0/0 -> ok
interface 0/0.1 -> ok
interface 0/0.2 -> ok
interface 0/0.3 -> ok
interface 0/0.5 -> ok
interface 1/0 -> not showing
interface 2/0 -> ok
i checked configuration and all interfaces have the following commands configured:
ip flow ingress
ip flow egress
ip route-cache flow
also main router config has the following commands configured:
ip flow-export version 5
ip flow-export destination 172.16.X.X 2055
anyone faced this problem before ?
