Configuring the Wireless Array
call two ports that are bonded
Gigabit
x
and
Gigabit
y
.

a.
Active Backup (gig ports fail over to each other)
— This mode
provides fault tolerance and is the default mode. Gigabit
x
acts as the
primary link. Gigabit
y
is the backup link and is passive. Gigabit
y
assumes the IP properties of Gigabit
x
. If Gigabit
x
fails, the Array
automatically fails over to Gigabit
y
. When a failover occurs in this
mode, Gigabit
y
issues gratuitous ARPs to allow it to substitute for
Gigabit
x
at Layer 3 as well as Layer 2. See Figure 95 (a).
??Are more
than 2 ports in this bond OK? How would it work??

b.
Aggregate Traffic from gig ports using 802.3ad
— The Array sends
network traffic across all member Gigabit ports to increase link speed
to the network. These ports act as a single logical interface (trunk),
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
