https://community.extremenetworks.com/t5/extremeswitching-exos-switch/port-load-sharing/m-p/23198#M2210 Load sharing is not the same as load balancing. EXOS does load sharing (link aggregation), but not load balancing. As Parthiban and Jarek have mentioned, you can adjust the hash algorithm to attempt to better spread the traffic across the links.<BR /> <BR /> I'd like to try to understand your use case. Is there a problem with the traffic favoring one link over another, or is it just a preference to have it balanced? What type of traffic is between these two switches? Using the L3_L4 algorithm, you could see one link more saturated than the other if the IP address and protocol port is the same for a majority of the traffic. If you use the L2 algorithm, it will be based on the MAC address of the source and destination systems - if they are the same, only one link will be chosen.<BR /> Tue, 02 Dec 2014 22:49:00 GMT Drew_C 2014-12-02T22:49:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/port-load-sharing/m-p/23177#M2189 After i enable Lacp .. port is not sharing.
