| * ''-1'' — without load balancing — the packet is sent to the paired bridge port | * 0 (default) - LACP is disabled, SSG does not hold LAG, but freely skips it |

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.
