20.2.7 DCBX
DCBX uses LLDP (Link Layer Discovery Protocol) to exchange PFC, ETS and application priority
information between switches. PFC information should be consistent between switches, so this can be
configured automatically using DCBX.
See Chapter 44 on page 178
In order for switches to exchange information, they must send their type-length values (TLVs) in order to
be able to read each other's information.
The following table lists the commands for this feature.
