Configuring Trunk Groups and Dynamic Link Aggregation
December 2005

10 - 7
Table 10.3 shows how the FESX, FWSX, and FSX load balance traffic across the ports in a trunk group, if the
device is running FESX/FWSX software release 02.2.00 or later or FSX software release 02.1.00 or later.
Likewise, Table 10.4 shows how a FESX and FSX load balance traffic across the ports in a trunk group, if the
device is running a FESX/FWSX software release prior to 02.2.00 or a FSX software release prior to 02.1.00.
Note that load balancing on the FESX and FSX is hardware-based.
NOTE:
There is no change in load balancing for routed traffic, which is always based on the source and
destination IP addresses and protocol field.
.
Configuring a Trunk Group
To configure a trunk group, do the following:
1.
Disconnect the cables from those ports on both systems that will be connected by the trunk group. Do not
configure the trunk groups with the cables connected.
