TLB Automatic Method
Automatic is a load-balancing method that is designed to preserve frame ordering.
This method will load balance outbound traffic based on the highest layer of information in the
frame. For instance, if a frame has a TCP header with TCP port values, the frame will be load
balancing by TCP connection (refer to
“TLB TCP Connection Method”
below). If the frame has
an IP header with an IP address but no TCP header, then the frame is load balanced by destination
IP address (refer to
“TLB Destination IP Address Method”
below). If the frame doesn’t have an
IP header, the frame is load balanced by destination MAC address (refer to
“TLB Destination
MAC Address Method”
below).
Automatic is the HP-recommended setting for outbound load balancing. Although in the current
product Automatic mode is identical to TCP Connection mode, future releases may augment
