IP distribution for a LAG (ifgrp) may not be optimally balanced in ONTAP
Applies to
- ONTAP 9
- Interface group (IFGRP)
- Link Aggregation Group (LAG)
Issue
- The LAG (Link Aggregation Group/IFGRP) is not evenly transmitting traffic across the participating ports evenly when using IP based distribution.
- Low throughput after ONTAP upgrade from 9.1 to 9.7.
system node run -node <nodename> -command ifstat -a
shows unequal load distribution across the participating ports in theTRANSMIT
section.
