Trunking Masters
The trunking master implicitly defines the trunking group. All ports with the same master are
considered to be part of the same group. Each trunking group includes a single trunking master and
from 1 to 3 trunking slave links. The first ISL found in any trunking group is assigned to be the
trunking master, also known as the principal ISL. After the trunking group is fully established, all
data packets intended for transmission across the trunk are dynamically distributed at the frame
level across the ISLs in the trunking group, while preserving in-order delivery.
