Greetings fellow toaster admins
I hope someone can shed some light on the IP distribution function for lacp ifgrps.
We have a four port, multi mode lacp ifgrp, a0a, using interfaces e2a-e2d. We observe SnapMirror traffic egressing port e2c.
The XOR of the last two bits of the source and destination IPs are either x0 or x3 so I am expecting traffic to egress either the first or fourth port in the ifgrp.
Assuming e2a is port 0, e2b is port 1, etc., I would expect traffic to egress either e2a (0x0) or e2d (0x3).
What am I missing? I can’t find any details about the actual hashing function for IP distribution or port member indexing in an ifgrp to confirm my assumptions.
Both clusters are a single A250 HA pair running 9.15.1.
I’m typing this with my thumbs so apologies for any typos or insufficient detail.
Best wishes
Stephen
