I am trying to understand how the algorithm for Etherchannel load balancing works. If is select port-channel load-balance src-ip and i have say 4 channel members (g1/0/1,g1/0/2,g1/0/3,g1/0/4) lets assume that IP1 goes to g1/0/1 when all are active. If g1/0/4 goes down, will IP1 still remain on g1/0/1 or will it be re-assigned? The question really is whether the traffic assigned to a link will be remain on the link if another member fails?
The EtherChannel Frame distribution hashing algorithm performs an XOR operation on one or more low-order bits of the addresses. For a 2 port bundle the last bit is used. For a 4 port bundle the last two bits are used. For an 8 port bundle the last 3 bits are used. If a link fails then the traffic will move to the remaining links. Hope this helps.. Please rate...
