Administrator Guide

Usage Information
You can configure 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 configuration 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.
Configure DCBX operation at the INTERFACE level on a switch or globally on the switch. To verify the DCBX
configuration on a port, use the show interface dcbx detail command.
dcbx port-role
Configure the DCBX port role the interface uses to exchange DCB information.
Syntax
dcbx port-role {config-source | auto-downstream | auto-upstream | manual}
To remove DCBX port role, use the no dcbx port-role {config-source | auto-downstream |
auto-upstream | manual} command.
Parameters
config-source |
auto-downstream
| auto-upstream |
manual
Enter the DCBX port role, where:
• config-source: configures the port to serve as the configuration source on the
switch.
• auto-upstream: configures the port to receive a peer configuration. The
configuration source is elected from auto-upstream ports.
• auto-downstream: configures the port to accept the internally propagated DCB
configuration from a configuration source.
• manual: configures the port to operate only on administer-configured DCB
parameters. The port does not accept a DCB configuration received form a peer or a
local configuration source.

Usage Information
DCBX requires that you enable LLDP to advertise DCBX TLVs to peers.
Configure DCBX operation at the INTERFACE level on a switch or globally on the switch. To verify the DCBX
configuration on a port, use the show interface dcbx detail command.
If you use the auto-upstream option and the port does not come up on a switch from a different vendor,
manually configure the version a CEE on the peer device.
