When a failed link is returned to service, aggregation keying restores load
sharing across all links.
Figure 7-30 illustrates a 300 Mbps LAN connection over two aggregated 150
Mbps links.
• The aggregation process ensures that any one traffic stream is only transported
over one link.
• Load sharing generally ensures an equitable traffic split
• Each link provides redundancy for the other.
• The aggregation option is selected in the Plug-ins screen.

Basic 300 Mbps L2 Link Aggregation: Two 150 Mbps Links
Figure 7-31 illustrates aggregation of four 150 Mbps links. In the top link, C1/C2
link aggregation is selected. In the lower link C1/C2/P1 aggregation is selected.
Link Status Propagation should be enabled for the top link. See Link Status
Propagation Operational Characteristics on page 7-81.
The diagram also illustrates DAC GE VLAN tagging. Three company VLANs
are DAC GE VLAN tagged (double tagged) and carried as a trunked VLAN on
the aggregated links. VLAN tagging is selected in the VLAN Tagging screen.
