Link Aggregation Configuration Example
11-12 Configuring Link Aggregation
on each device is to ensure that LAGs form only where we configure them. Since the admin key
for the LAG and its associated ports must agree for the LAG to form, an easy way to ensure that
LAGs do not automatically form is to set the admin key for all LAGS on all devices to a non-
default value. The physical ports will initially retain admin key defaults. In our example, the
admin keys for all LAGs are set to the highest configurable value of 65535.
Figure 11-3 Link Aggregation Example
Both physical port and LAG admin keys will be set as shown in Table 11-6 to ensure that the LAGs
form only for the desired ports.
