Usage Information
You can congure the transmission of more than one TLV type at a time; for example: advertise dcbx-tlv
ets-conf ets-reco.
You can enable ETS recommend TLVs (ets-reco) only if you enable ETS conguration TLVs (ets-conf). To
disable TLV transmission, use the no form of the command; for example, no advertise dcbx-tlv pfc
ets-reco
.
DCBX requires that you enable LLDP to advertise DCBX TLVs to peers.
Congure DCBX operation at the INTERFACE level on a switch or globally on the switch. To verify the DCBX
conguration on a port, use the show interface dcbx detail command.

The unit of bandwidth percentage is 1%. A bandwidth percentage of 0 is allowed and disables the scheduling of
that class. If the sum of the bandwidth percentages given to all eight classes exceeds 100%, the bandwidth
percentage automatically scales down to 100%.
