Reference Guide

Version Description
9.7(0.0) Introduced on the Z9500.
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.
