Hi We have 2 C6509 with an MSFC2 module, these switches are configured as a redundant pair using hsrp on the MSFC. we now need to enable netflow on the msfc for all traffic that pass on the uplink to our core routers (Vlan 900). I have entered the following config and netflow is exporting data to my netflow collector, the problem is that only a small fraction of the actual throuput is reported on the netflow collector. I have checked cisco website but cannot find any adtional information. Anny assistace as greatly apreciated Config follows ip flow-cache entries 131072 ip cef !interface Vlan1 ip address 192.168.105.2 255.255.255.0 no ip redirects no ip mroute-cache standby 1 priority 90 standby 1 ip 192.168.105.1 standby 1 track Vlan900 50 ! interface Vlan900 ip address 196.26.0.206 255.255.255.0 ip route-cache flow ! ip flow-export version 5 peer-as ip flow-export destination 192.168.100.100 9996 _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
