     LAGs can include either regular ports or on-stick ports, no mixing is allowed. LAG on on-stick is organized on the base (physical) port. LAG is implemented in fastDPI at logical level: there is no single bond device, inside fastDPI work is done with ports as before. LAGs can include either regular ports or on-stick ports, no mixing is allowed.

     The type of the applied balancing algorithm is specified by the ''lag.balance_algo'' parameter: The type of the applied balancing algorithm is specified by the ''lag.balance_algo'' parameter:
    -  * ''0'' - balancing by internal ''session_id'' (default balancing). The ''session_id'' is used as the hash. +  * ''-1'' — without load balancing — the packet is sent to the paired bridge port 
    -  * ''1'' - no balancing - the packet will be sent to the paired bridge port. +  * ''0'' (default) — load balancing by internal ''session_id'' (default balancing). ''session_id'' is used as the hash

     +=====Diagnosis=====
     +LACP diagnostics is performed using the pcap entry. To do this, the parameter ''pcap'' must be added to the LAG description.\\
     +Parameter values: 
     +  * on — enable pcap recording
     +  * off — disable pcap recording
