Dynamic link aggregation
12
Figure 83 shows an example of 2-port groups in a range of four ports on which link aggregation is
enabled. Based on the states of the ports, some or all of them will be eligible to be used in an
aggregate link.
FIGURE 83 Two-port groups used to determine aggregation eligibility
Table 74 shows examples of the ports from Figure 83 that will be eligible for an aggregate link
based on individual port states.
As shown in these examples, all or a subset of the ports within a port range will be eligible for
formation into an aggregate link based on port states. Notice that the sets of ports that are eligible
for the aggregate link must be valid static trunk configurations.
Enabling dynamic link aggregation
By default, link aggregation is disabled on all ports. To enable link aggregation on a set of ports,
enter commands such as the following at the Interface configuration level of the CLI.
