ESXi Management not working with SG500 LAG

Question

I am setting up a 3 host ESXi cluster. I am using a pair of stacked SG500-28 switches for switching redundancy. Each host has 8 NICs. 4 to each switch. I have successfully setup a 3 NIC LAG with 1 path to one switch and 2 paths to the other. These LAGs work. When I setup a 2NIC LAG via the console for management, and the associated ports on the switches, I lose managment communication with the host. Before setting up the LAG in the ESXi console, I set that vswitch properties to us IPHASH as instructed here bit.ly/VLaTEt I have attempted to follow those instructions as closely as possible. The one thing that I am wondering is whether the SG series supports etherchannel. I can't find any reference. Either way, it works on the other vswitch that is for vMotion. I can vmkping between the hosts over that LAG. But setting up a LAG on the management vSwitch doesn't?
Thanks,
Stephen

Port Management > Link Aggregation > LAG Management.

• IP/MAC Address—Perform load balancing by the source and destination IP

Here's a good document

Enabling either Route based on IP hash without 802.3ad  aggregation or vice-versa disrupts networking, so you must make the  changes to the virtual switch first. That way, the service console is  not available, but the physical switch management interface is, so you  can enable aggregation on the ports involved to restore networking.
