I don't sure meaning of "link group" is aggregate. If yes = A correct.

1. Select NetworkInterfacesEthernet and Add Aggregate Group.
2. In the field adjacent to the read-only Interface Name, enter a number to identify the aggregate group. The range is 1 to the maximum number of aggregate interface groups supported by the firewall.
3. For the Interface Type, select HA, Virtual Wire, Layer2, or Layer3.

An Aggregate Ethernet (AE) interface group on Palo Alto firewalls uses IEEE 802.1AX/802.3ad link aggregation to bundle multiple physical Ethernet interfaces into one logical interface. The supported interface types for the group are:

>Layer 2
>Layer 3
>Virtual Wire
>HA3 (the packet-forwarding link in an Active/Active High Availability configuration)
