Applies to
- ONTAP 9.2 and later
- IP Fastpath
Issue
- TCP/UDP port 2049 responses may fail to egress after an upgrade to ONTAP 9.2 or later
- TCP/UDP traffic ingresses via one interface and egresses out a different interface
- Few NFS and/or CIFS resources are not accessible after upgrade to ONTAP 9.2 or later
