Issue
LIFs on the port cannot be accessed even if the port is up and healthy.
Ping from LIFs on the affected port is unsuccessful:
::> network ping -vserver <vserver_name> -lif <lif_name> -destination XXX.XXX.XXX.XXX
no answer from XXX.XXX.XXX.XXX
Ping from the destination host to affected LIFs is also unsuccessful.
No firewall between ONTAP and the destination host or ICMP port is allowed.
