call two ports that are bonded Gigabitx and Gigabity. x Shelly - paginate
and check refs for XR and XN versions!!
a. Active Backup (gig ports fail over to each other) — This mode
provides fault tolerance and is the default mode. Gigabitx acts as the
primary link. Gigabity is the backup link and is passive. Gigabity
assumes the IP properties of Gigabitx. If Gigabitx fails, the Array
automatically fails over to Gigabity. When a failover occurs in this
mode, Gigabity issues gratuitous ARPs to allow it to substitute for
Gigabitx 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
