ACI Multiple MACs on a Host

[selif]

Hello everyone,

I have got a question about ACI. We are setting up new virtual machines that will work as a HA cluster (vNIOS HA pair). And It has been said to us that the port profile which the LAN ports and vNIOS HA will connect should allow more than one MAC per vNIC. These hosts will be directly connected to ACI leaves, would multiple MAC for vNIC be a problem and if so how can it be solved?

hello @selif 
there is no Problem with multiple MACs, make sure that the IP Aging function in ACI enabled so you can keep the reachability to the cluster's members.
this you can enable it under System>System Settings>End Points Control >IP Aging  > administrative State enable 

hopefully that was helpful.
best regards
