Set Up Ethernet Port Aggregation
Ethernet aggregation lets you combine two Gigabit Ethernet ports to 
improve the aggregated file transfer speed. If a device supports Ethernet 
aggregation, you can use the Ethernet aggregate ports 1 and 2 to cable 
the device that supports Ethernet port aggregation to the router. 
Note:  Ethernet port aggregation is also referred to as link aggregation, 
teaming port, and port trunking.
 ¾ To set up Ethernet port aggregation:
1.  If you are connecting a switch, make sure that the switch supports 
802.3ad LACP.
You must configure the switch before you connect the Ethernet 
cables to the router.
Warning:  To avoid causing broadcast looping, which can shut down 
your network, do not connect an unmanaged switch to Ethernet 
aggregate port 1 and port 2 on the router.
2.  Use Ethernet cables to connect a device that supports Ethernet 
port aggregation, such as a NAS or network switch, to Ethernet port 
1 and port 2 on the router.
