Hi Everyone,

I have an issue with Netflow lite when testing it on a 2960X.

It seems that no flows are send to my collector.

Below the relevant config and som show outputs.

Can someone see what I did wrong or guid me to find a solution?


flow record record1
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
collect interface input
collect counter bytes long
collect counter packets long
collect timestamp sys-uptime first
collect timestamp sys-uptime last
flow exporter export1
template data timeout 60
flow monitor monitor1
record record1
exporter export1
cache timeout inactive 120
cache timeout active 300



sampler sampler1
mode random 1 out-of 100

interface GigabitEthernet1/0/1
ip flow monitor monitor1 sampler sampler1 input
