I have two servers connected to a pair of Nexus 7K (peers). Each server is connected to a 4 port LACP port channel (vPC, I think). The switch and all modules are using the default load balance hash mode.... i.e..
show port-channel load-balance
Non-IP: src-dst mac
IP: src-dst ip rotate 0
Each of my servers (on the same tcp subnet), when using multiple tcp connections and ports, can utilize all 4 ports sending flows. However, the receiver of these flows is only receiving on two of the 4 ports. Would switching the port channel load balance mode to src-dst-port allow the sending and receiving tcp port numbers to included in the hash, and thus have the switch send flows to my receiver on all 4 links?
It seems like it would, but I've been led to believe that since the traffic is all layer 2, it will not. I'm not sure if I should believe that.
Thanks for your thoughts.
Solved! Go to Solution.
Thank you! It would be nice if there was Cisco documentation I could point to that made it clear.
