runner - mode

1) activebackup :링크 변경을 감시하고 active port 다운시 backup으로 넘어감

 

2) loadbalance : 트래픽을 모니터링하고 패킷 전송에 대한 포트를 선택할 때 완변학 균형에 도달하기 위해 hash function을 사용

 

3) lacp : 802.3ad 링크 표준 loadbalance runner와 동일한 전송

 

4) broadcast : simple한 runner로 이것은 모든 포트로 부터 각각의 패킷을 전송

 

5) roundrobin : simple한 runner로 이것은 각 포트에서 라운드 로빈 방식으로 각각의 패킷을 전송
