     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 
    -  * ''2'' - hash from ''flow key <srcIP, dstIP, srcPort, dstPort, proto>''. If there is no flow - balance by ''session_id''+  * ''1'' — hash based on ''flow key <srcIP, dstIP, srcPort, dstPort, proto>''. if there is no ''flow'', balancing is performed by ''session_id''
        
     Additional hash configuration parameters in the ''lag'' section: ''hash_seed'', ''hash_offset'', ''hash_bits''\\ How many significant bits we take from the 64-bit hash during balancing. The balancing algorithm in the general case looks like this: Additional hash configuration parameters in the ''lag'' section: ''hash_seed'', ''hash_offset'', ''hash_bits''\\ How many significant bits we take from the 64-bit hash during balancing.
