We used to collect full unsampled Netflow from two 7613 routers. Both ran
12.2(18)SXF11 and all was well.
We continue to get flow data as follows from the 12.2(18)SXF router:
Flow export v5 is enabled for main cache
Exporting flows to xxx.139.197.76 (9800) xx.229.0.7 (8888)
Exporting using source interface Loopback0
Version 5 flow records, origin-as
35057147 flows exported in 1168572 udp datagrams
We upgraded the other 7613 to 12.2(33)SRE6 - and most of the flow data no
longer appears in our collector. Yet:
gp1#sho ip flow export
Flow export v5 is enabled for main cache
Export source and destination details :
VRF ID : Default
Source(1) xxx.139.220.90 (Loopback0)
Destination(1) xxx.139.197.76 (9800)
Version 5 flow records, origin-as
28312144 flows exported in 943738 udp datagrams
It appears like we should be getting flow data but we are not.
We have a very simple Netflow setup. On most GigE and 10GigE interfaces we
have defined:
ip flow ingress
and globally we have defined:
ip flow-cache entries 120000
mls flow ip interface-full
This used to work pre-12.2(33)SRE. Something must have changed that we are
not aware of that needs to be defined. Any ideas?
Thanks,
Hank
