12 Dynamic link aggregation 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 Group 1 Group 2 Port1/1 Port1/2 Port1/3 Port1/4 Table 74 shows examples of the ports from Figure 83 that will be eligible for an aggregate link based on individual port states. TABLE 74 Port eligibility for link aggregation Port group 1 Port group 2 Trunk eligibility 1/1 1/2 1/3 1/4 Link State Up Up Up Up Down Up Up Up Down Up Down Down Up Up Up Down Down Down Up Down Down Up Up Down 4-port 1/1 - 1/4 4-port 1/1 - 1/4 4-port 1/1 - 1/4 4-port 1/1 - 1/4 2-port 1/3 - 1/4 2-port 1/1 - 1/2 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. 414 PowerConnect B-Series FCX Configuration Guide 53-1002266-01
