Hi Friends - I am trying to findout what astreik (*) indicates in the command "show ip flow top-talkers".
I read in the command reference that The asterisk (*) immediately following the "DstIf" field indicates that the flow being shown is an egress flow.
But i see the same 2 flows (having the same source, destination, destination interface), one showing with * and other donot. Can you please explain the why it please
rtr1#show ip flow top-talkers
SrcIf SrcIPaddress DstIf DstIPaddress Pr SrcP DstP Bytes
Po1.2 10.212.16.45 Se0/3/0.777* 172.22.49.41 06 2F30 FA96 317K
Po1.2 10.212.16.45 Se0/3/0.777 172.22.49.41 06 2F30 FA65 310K
Po1.2 10.212.16.45 Se0/3/0.777 172.22.49.41 06 2F30 FA69 219K
Po1.2 10.212.16.45 Se0/3/0.777* 172.22.49.41 06 2F30 FA69 180K
10 of 10 top talkers shown. 1293 flows processed.
Thanks in advance

Hi John Thank you for the response.
Though i can understand that * means egress flow, where i got confused is, why the first line of the below output having *, whereas the next line doesn't have, thougt the traffic pattern is same .
rtr1#show ip flow top-talkers
SrcIf SrcIPaddress DstIf DstIPaddress Pr SrcP DstP Bytes
Po1.2 10.212.16.45 Se0/3/0.777* 172.22.49.41 06 2F30 FA96 317K

It could be because the etherchannel is the source and it could possibly coming over a different link in the channel group, but it's still in the egress direction, so I'm not sure why you wouldn't have the * listed.

Hi,
I am assuming that you config is like this
!
int Po1.2
ip flow ingress
!
int Se0/3/0.777
ip flow egress
!
Now the same flow is going to be captured by both of these interfaces. One with the * is the flow that is captured by the ip flow egress command on the Serial link.
Hope that answers your question.

Hi John & Vishesh - Thank you for your expert response
Here is the configuration i have taken from the same router
interface Serial0/3/0.777 point-to-point
ip flow ingress
ip flow egress
end
interface Port-channel1.2
ip flow ingress
end
regads,
