Cisco UCS vNIC Failover and LAN Pin Groups - best practice

Mohammed Islam

Hi experts!

I have a question around vNIC failover and LAN pinning.

1) I understand what when you enable failover on a vNIC say on FI A, it creates a Standby/Passive VIF/circuit on FI B.  In doing so, I guess you will have to manually LB the vNIC's accordingly for a particular SP should you want to LB the traffic.  Also, is there any reason for NOT enabling vNIC FO and just create another vNIC for the other FI and just allow UCS to manage the FO?  I assume in the latter example dynamic LAN pinning come into play to send traffic to both FI's?

2) In regards to LAN pin groups, is it best to just allow the UCS manage the pinning or is it better to maually specify the the FI's?  Coming from a network background, I thought it was best to know which way your traffic is traversing so in situations of TS you know exactly which way your traffic is flowing, however reading various articals it says otherwise?

FYI, we do not have any nic teaming or OS level NIC FO.  However we do have N1K with HA, if that matters.

Thanks in advance.

Regards

Mo
