Device: Summit X460-24x
ExtremeXOS version 15.4.1.3

NLB configuration.
It is being made to integrate a VMware virtualized system which used Network Load Balance, I use LACP main ports of group 1: 2 to 1:12

enable sharing 1:2 grouping 1:2, 1:4, 1:6, 1:8 algorithm address-based L2 lacp
enable sharing 1:12 grouping 1:12-14, 1:16 algorithm address-based L2 lacp

The IP 192.168.206.95 NLB server associated with the multicast address

## Module fdb configuration.
#
create fdbentry 03: bf: c0: a8: ce: 5f vlan "Servers" port 1: 2, 1: 12
iparp configure add 192.168.206.95 Default vr VR-03: bf: c0: a8: ce: 5f

The need is that from the VLANS to access the server IP 192.168.206.95

Hi,

Are you speaking of Microsoft's NLB? That looks like it, but I want to make sure.
This switch is pure L2, or is it doing the L3 part as well? The config snippet doesn't show the routing config, but you are resolving the ARP on it, so that's ambiguous.
