Currently each is connected to a separate Juniper switch stack via an LACP VIF of two 10Gb connections, as in the first diagram. As switch stack reboots (for firmware upgrade etc.), cause an outage, what I want to do is connect them as in the second diagram and then have a VIF of VIFS. I understand this is possible, but the question is how do you ensure that under normal circumstances traffic only uses the 2 x 10Gb connection. With Juniper switches you can’t span LACP groups across switch stacks.</P><P class="MsoNormal"></P><P class="MsoNormal"><IMG src="http://community.netapp.com/legacyfs/online/22582_network.jpg" /></P><P class="MsoNormal"><SPAN style="mso-fareast-language: EN-GB; mso-no-proof: yes;"><IMG height="529" src="https://community.netapp.com/" width="321" /></SPAN></P><P class="MsoNormal"></P><P></P></BODY></HTML> Thu, 05 Jun 2025 05:56:03 GMT nigelg1965 2025-06-05T05:56:03Z Network traffic flow in a VIF of VIFs https://community.netapp.com/t5/ONTAP-Discussions/Network-traffic-flow-in-a-VIF-of-VIFs/m-p/62826#M14842 <HTML><HEAD></HEAD><BODY><P></P><P class="MsoNormal">I wonder anyone has any experience/expertise they can share. </P><P class="MsoNormal"></P><P class="MsoNormal">We’ve a FAS3240 HA pair running 8.0.2P6 7-mode, but likely to be upgraded to 8.1.3 7-mode soon.
