I need to check the load balancing mode of the lags on the physical switches (ICX6610, 08.0.30t) facing our esxi cluster. On the cluster side, at the virtual switches, the balancing mode is currently "Source and destination IP address". The manual is a bit vague of the modes and I can't seem to find a command to modify the mode in the physical switch.
The manual says (a snippet...):
Layer 2 Bridged TCP/UDP: Source and destination MAC addresses, source and destination IP addresses, and source and destination TCP/UDP
... Layer 2 Bridged IPv4
Source and destination IP addresses, and source and destination TCP/UDP ports.
So what is the difference here with "bridged tcp/udp" and "bridged ipv4 tcp/udp"? And are those different, selectable modes?
Eg "src & dst ip address and tcp/udp port" is one of the possible selections on the cluster side. Would that be a better combination for icx?
LAG load balancing is fixed and cannot be changed, the method used depends on the traffic type (this is described in the L2 config guide). Symmetric load balancing can be enabled if required (some firewalls need this) but it does not alter the traffic distribution across the links.
