USAGE GUIDELINES
■
When configuring static trunks, you may not be able to link switches of different types,
depending on the manufacturer's implementation. However, note that the static trunks on this
switch are Alba Ether Channel compatible.
■
To avoid creating a loop in the network, be sure you add a static trunk via the configuration
interface before connecting the ports, and also disconnect the ports before removing a static
trunk via the configuration interface.
■
When incoming data frames are forwarded through the switch to a trunk, the switch must
determine to which port link in the trunk an outgoing frame should be sent. To maintain the
frame sequence of various traffic flows between devices in the network, the switch also needs to
ensure that frames in each “conversation” are mapped to the same trunk link. To achieve this
requirement and to distribute a balanced load across all links in a trunk, the switch uses a hash
algorithm to calculate an output link number in the trunk. However, depending on the device to
which a trunk is connected and the traffic flows in the network, this load-balance algorithm may
result in traffic being distributed mostly on one port in a trunk. To ensure that the switch traffic
load is distributed evenly across all links in a trunk, the hash method used in the load-balance
calculation can be selected to provide the best result for trunk connections. The switch provides
four load-balancing modes as described in the following section.
