Hi, have just setup netflow on an 857 running 12.4(15)T9 and am confused with the number of interfaces im able to capture. I've enabling net flow individually on both the dialer and the internal vlan1 interfaces and both show two interfaces (Interface 12 & 16 in this instance) to capture from in RTNFA.
ip flow-export source Vlan1
ip flow-export version 5
ip flow-export destination 192.168.73.1 2055
