Hint§
The switch provides five load-balancing methods to distribute a balanced load across all links in a
trunk. The following parameters are displayed on the Trunk Distribution Algorithm Setting:
■ Distribution Algorithm Parameters—To ensure the switch traffic load is distributed evenly across
all links in a trunk, the hash methods used in the load-balance calculation can be selected to provide the
best result for trunk connections. The following options are supported:
■ Source Port - All traffic with the same source and destination TCP/UDP port number is output
on the same link in a trunk. Avoid using his mode as a lone option. It may overload a single port
member of the trunk for application traffic of a specific type, such as web browsing. However, it
can be used effectively in combination with the IP Address option.
■ Source MAC - All traffic with the same source MAC address is output on the same link in a
trunk. This mode works best for switch-to-switch trunk links where traffic through the switch is
received from many different hosts.
■ Destination MAC - All traffic with the same destination MAC address is output on the same
link in a trunk. This mode works best for switch-to-switch trunk links where traffic through the
switch is destined for many different hosts. Do not use this mode for switch-to-router trunk links
where the destination MAC address is the same for all traffic.
■ Source IP - All traffic with the same source and destination IP address is output on the same
link in a trunk. This mode works best for switch-to-router trunk links where traffic through the
switch is destined for many different hosts. Do not use this mode for switch-to-server trunk links
where the destination IP address is the same for all traffic.
■ Destination IP - All traffic with the same source and destination IP address is output on the
same link in a trunk. This mode works best for switch-to-router trunk links where traffic through
the switch is destined for many different hosts. Do not use this mode for switch-to-server trunk
links where the destination IP address is the same for all traffic.
