IP flow monitor output

[t-van]

I tried to issue command ip flow monitor ..... output on a trunk interface on switch 2960x, but it errrored out with could not be added to interface due to invalid sub-traffic type: 0.  We have a Cisco One license and running on c2960x-universalk9-mz.152-5.E2.bin.  Does anyone experience with this error and how to fix it?  or the switch just doesn't support the output?  Thanks all.

Hi

you tried to add ip flow a layer 3 command to a layer 2 trunk port , it needs to be added to the vlan svi interface on a latyer 2 switch or else use the

As well if your trying to collect layer 2 fields make sure the specific mac fields are in place

Thanks.  Basically the output command can't be issue on a interface alone.

This link refers to 4500 series but the same limitation may also  may apply to the 2960x series
