32 Switch ConfigurationDCB SupportDCB enhancements for data center networks are supported to eliminatepacket loss and provision links with required bandwidth. On the MXL10/40GbE Switch, you must manually configure DCBX port roles to enablethe switch to auto-configure its DCB settings to match the DCB configurationin the ToR switches to which it connects.FCoE ConnectivityMany data centers use Fiber Channel (FC) in storage area networks (SANs).Fiber Channel over Ethernet (FCoE) encapsulates Fiber Channel frames overEthernet networks.On a MXL 10/40GbE Switch, the internal ports of the MXL 10/40GbESwitch support FCoE connectivity and connect to the converged networkadapter (CNA) in blade servers. FCoE allows Fiber Channel to use10-Gigabit Ethernet networks while preserving the Fiber Channel protocol.You must manually configure the FCoE settings on the MXL 10/40GbESwitch to match the FCoE settings used in the ToR switches to which itconnects.iSCSI OperationSupport for iSCSI traffic is turned on by default when the MXL 10/40GbESwitch powers up.The MXL 10/40GbE Switch monitors known TCP ports for iSCSIsessions.When a session is detected, an entry is created and monitored as longas the session is active.The MXL 10/40GbE Switch also detects EqualLogic iSCSI storage devices onall interfaces and auto-configures to optimize performance. Performanceoptimization operations, such as Jumbo frame size support, STP port-statefast, and disabling of storm control on interfaces connected to an EqualLogiciSCSI storage device, are applied automatically.CLI configuration is necessary only when the configuration includes iSCSIstorage devices that cannot be automatically detected and when non-defaultQoS handling is required.
