Version 8.3.16.0 Introduced on the MXL 10/40GbE Switch IO Module.
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.
S4820T
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.
