Parameters pfc-queues Enter the pfc-queue range. To disable DCB, use the no dcb enable command. Range: 1 or 2. Defaults None Command Modes CONFIGURATION 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, iSCSI is disabled and flow control is not configured on any interfaces or if link-level flow control is enabled on one or more interfaces. To enable DCB, do one of the following: • Apply the dcb-input policy command with the command no pfc-mode on to all the interfaces. • Disable flow-control on all of the interfaces. Example FTOS(conf)#dcb enable pfc-queues PFC lossless queues profile dcb-input S6000 Syntax Create a DCB input policy to apply pause or flow control for specified priorities using a configure delay time. dcb-input policy-name To delete the DCB input policy, use the no dcb-input command. Parameters policy-name Maximum: 32 alphanumeric characters. Defaults None Command Modes CONFIGURATION Command History Version 9.0.2.0 Version 8.3.16.1 Introduced on the S6000. Introduced on MXL 10/40GbE Switch IO Module Usage Information As soon as you apply a DCB policy with PFC enabled on an interface, DCBX starts exchanging information with PFC-enabled peers. The IEEE802.1Qbb, CEE, and CIN versions of PFC TLV are supported. DCBX also validates PFC configurations received in TLVs from peer devices. By applying a DCB input policy with PFC enabled, you enable PFC operation on ingress port traffic. To achieve complete lossless handling of traffic, you must also enable PFC on all DCB egress ports or configure the dot1p priority-queue assignment of PFC priorities to lossless queues (see pfc no-drop queues). To remove a DCB input policy, including the PFC configuration it contains, enter the no dcb-input policy-name command in interface configuration mode.
