DES-3326 Layer 3 Fast Ethernet Switch User’s Guide
designated as the master port of the group. Since all members of the link aggregation group must be
configured to operate in the same manner, the configuration of the master port is applied to all
members of the link aggregation group. Thus, when configuring the ports in a link aggregation group,
you only need to configure the master port.
The DES-3326 supports link aggregation groups, which may include from 2 to 8 switch ports each,
except for a Gigabit link aggregation group which consists of the 2 (optional) Gigabit Ethernet ports of
the front panel. These ports are the two 1000BASE-SX, -LX –TX or GBIC ports contained in a front-
panel mounted module.

Figure 5-7. Link Aggregation Group
Data transmitted to a specific host (destination address) will always be transmitted over the same port
in a link aggregation group. This allows packets in a data stream to arrive in the same order they were
sent. A aggregated link connection can be made with any other switch that maintains host-to-host data
streams over a single link aggregate port. Switches that use a load-balancing scheme that sends the
packets of a host-to-host data stream over multiple link aggregation ports cannot have a aggregated
connection with the DES-3326 switch.
