I've been doing netflow reporting on my 7206 for awhile now. Since my IOS doesn't support egress, I enable "ip route-cache flow" on all the interfaces (the BGP uplinks, and links that go downstream to equipment). On the 7206 I am running IOS 12.0(28d).
I am replacing the 7206 with a 6509 with Sup2 engines. The 6509 is currently running 12.2(18)SXD7b.
I proceeded to config netflow the way I did on the 7206:
"ip route-cache flow" on all active interfaces, and:
ip flow-export destination X.X.X.X 8787 ip flow-export version 5 origin-as
for the export. Destination host is FreeBSD box running flow-tools.
So here the problem. I am only seeing flow data for one interface, mainly my uplink:
# sh ip cache flow
SrcIf SrcIPaddress DstIf DstIPaddress Pr SrcP DstP Pkts Fa7/1 220.127.116.11 Local 18.104.22.168 01 00000800 2 Fa7/1 22.214.171.124 Null 126.96.36.199 06 E99A 0017 2 Fa7/1 188.8.131.52 Null 184.108.40.206 11 F527 52D0 1 Fa7/1 220.127.116.11 Null 18.104.22.168 06 0ED7 361A 1 Fa7/1 22.214.171.124 Null 126.96.36.199 11 0A81 0035 2 Fa7/1 188.8.131.52 Null 184.108.40.206 11 0F75 059A 1 Fa7/1 220.127.116.11 Null 18.104.22.168 11 0637 059A 1
and thats it. No data for any of the the other interfaces like Fa7/2, Fa7/3 and so on. On these other interfaces are definitely live and pumping data.
Any ideas? Is it an IOS bug, or am I configuring the wrong way?
