Migrated from various hardware > 10200v and changed VLAN
We migrated from 8900/6900's to 10200V instances over the weekend and also changed from the basic untagged internal VLAN to a tagged vlan. This is on version 11.4.1 HF2 - I ran a iHealth file and found that with the new VLAN being tagged we have the following issue during failover:
BIG-IP objects configured on a different subnet than the self IP address do not send gratuitous ARP requests on failover: sol11880
Question is - if I add a Self-IP per subnet, do I have to do this off-hours? Or will it not cause an issue doing it in the middle of the day? Everything is working fine right now, but I want to be prepared properly for the failover and adding a self-ip per subnet is no problem for our envrionment (vs mac masquerading).
Also - should it be a floating IP or static per box?
