[j-nsp] LACP hashing algorithm

[junos fordummies]

Hi all,

This will sound like a very weird question, but has anyone seen a scenario
whereby an MX960 with 4 x 10G links always hashes (uses) a single link out
of the 40G bundle ? We have restarted the device, traffic flows in one
direction only use a single link, the reverse path is all 4 links in the
bundle. Both ends of the AE is MX960 running 16.1r2

Just wondering if anyone has seen anything similar ?

Many thanks

JfD.
