Defaults All PFC and ETS TLVs are advertised. Command Modes PROTOCOL LLDP Command History Version 9.0.2.0 Version 8.3.16.0 Introduced on the S6000. Introduced on 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 ETS configuration TLVs (ets-conf) are enabled. 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. bandwidth-percentage S6000 Configure the bandwidth percentage allocated to priority traffic in port queues. Syntax bandwidth-percentage percentage To remove the configured bandwidth percentage, use the no bandwidth-percentage command. Parameters percentage (Optional) Enter the bandwidth percentage. The percentage range is 1 to 100% in units of 1%. Defaults none Command Modes QOS-POLICY-OUT-ETS Command History Version 9.0.2.0 Version 8.3.16.0 Introduced on the S6000. Introduced on MXL 10/40GbE Switch IO Module Usage Information By default, equal bandwidth is assigned to each port queue and each dot1p priority in a priority group. Use the bandwidth-percentage command to configure bandwidth amounts in associated dot1p queues. When specified bandwidth is assigned to some port queues and not to others, the remaining bandwidth (100% minus assigned bandwidth amount) is equally distributed to unassigned non-strict priority queues in the priority group. The sum of the allocated bandwidth to all queues in a priority group should be 100% of the bandwidth on the link. ETS-assigned bandwidth allocation applies only to data queues, not to control queues. The configuration of bandwidth allocation and strict-queue scheduling is not supported at the same time for a priority group. If both are configured, the configured bandwidth allocation will be ignored for priority-group traffic when you apply the output policy on an interface. Data Center Bridging (DCB) | 319
