Defect Number:  
Enhancement Number:  

It is necessary to create a new profile in the Monitoring Center - Profiles and add new channels to the profile, eg. channels "IN" and "OUT".

Each channel will be defined by a filter that splits the traffic. 

Examples, of how to split the traffic:

  1. Using subnets
    src net in [,,] and not dst net in [,,]
    dst net in [,,] and not src net in [,,] 
    for internet upload/download
  2. Using interface indexes (if flow data are exported by routers/switches)
    [in|out] if <interface_index>
  3. Using VLANs
    [src|dst] vlan <num>
  4. Using AS numbers
    [src|dst] as in [ <ASlist> ]
  5. Some flow sources send also flow field "direction"
    dir [ingress|egress]
