<key>CSCuq03168</key> &amp; CSCuq14783: Microsoft Network Load Balancing support on Nexus 9300
Hi there I have a customer using Microsoft NLB which is migrating to Nexus 9300 Switches. NLB seems to be currently not supported, neither in unicast nor in multicast mode. Will the issue be resolved? If yes, - which NLB flavour will be supported: unicast, multicast or IGMP multicast? - what is the target release? Cheers, Heinz
