Configuring the Wireless AP 177
b. Aggregate Traffic from gig ports using 802.3ad — The AP sends
network traffic across all member Gigabit ports to increase link speed
to the network. These ports act as a single logical interface, using a
load balancing algorithm to balance traffic across the ports. For non-
IP traffic (such as ARP), the last byte of the destination MAC address
is used to do the calculation. If the packet is a fragment or not TCP or
UDP, the source and destination IP addresses are used to do the
calculation. If the packet is TCP or UDP over IP then the source IP
address, destination IP address, source port number and destination
port number are all used to do the calculation. The network switch
must also support 802.3ad. If a port fails, the connection degrades
gracefully — the other port still transmits. See Figure 103 (b).
c. Transmit Traffic on all gig ports — Transmits incoming traffic on all
Gigabit ports. Any traffic received on Gigabit ports is sent to the
onboard processor. This mode provides fault tolerance. See
Figure 104 (c).
