F5 Viprion bit size hash bit size in hardware for LACP

Dear all,


For optimal traffic distribution accross links inside a Trunk / LACP port channel it is important to know what bit size is used built inside the F5 hardware


As explained here a comparison between 3-bit and 8-bit where the first one is optimized for 2, 4 or 8 links the the 8-bit can be used for almost equal link distribution when using 6 links inside the Trunk.


I suppose the F5 hardware uses 3-bit hashing size built inside the Viprion hardware, but can someone confirm? Is it perhaps adjustable by perhaps using a database variable to switch between 3-bit and 8-bit?


The following article explains the hashing methods but it does not provide information about bit-size.
