Configuring a vswitch's load balancing policy is easy from Virtual Center, but whenever you are changing network setings on the fly its inevitable that you are going to make a change and loose connectivity to your ESX server. So I went in search of a command line way of seeing a vswitch's load balancing policy. I found two ways.
grep "teamPolicy\/team" /etc/vmware/esx.conf
This would return the following:
/net/vswitch/child0001/teamPolicy/team = "lb_srcid"
Note that your Possible load balancing policies are:
lb_srcid = Virtual port id
lb_ip = IP Hash
lb_srcmac = MAC Address
vmware-vim-cmd hostsvc/net/vswitch_info | grep -E '(policy|name)'
