32 Switch Configuration
DCB Support
DCB enhancements for data center networks are supported to eliminate 
packet loss and provision links with required bandwidth. On the MXL 
10/40GbE Switch,
 you must 
manually configure DCBX port roles to enable 
the switch to 
auto-configure its DCB settings to match the DCB configuration 
in the ToR switches to which it connects.
FCoE Connectivity
Many data centers use Fiber Channel (FC) in storage area networks (SANs). 
Fiber Channel over Ethernet (FCoE) encapsulates Fiber Channel frames over 
Ethernet networks. 
On a MXL 10/40GbE Switch, the internal ports of the MXL 10/40GbE 
Switch
 
support FCoE connectivity and connect to the converged network 
adapter (CNA) in blade servers. FCoE allows Fiber Channel to use 
10-Gigabit Ethernet networks while preserving the Fiber Channel protocol. 
You must manually configure the 
FCoE settings on the 
MXL 10/40GbE 
Switch 
to match the FCoE settings used in the ToR switches to which it 
connects.
iSCSI Operation
Support for iSCSI traffic is turned on by default when the MXL 10/40GbE 
Switch powers up. 
The MXL 10/40GbE Switch monitors known TCP ports for iSCSI 
sessions.When a session is detected, an entry is created and monitored as long 
as the session is active. 
The MXL 10/40GbE Switch also detects EqualLogic iSCSI storage devices on 
all interfaces and auto-configures to optimize performance. Performance 
optimization operations, such as Jumbo frame size support, STP port-state 
fast, and disabling of storm control on interfaces connected to an EqualLogic 
iSCSI storage device, are applied automatically.
CLI configuration is necessary only when the configuration includes iSCSI 
storage devices that cannot be automatically detected and when non-default 
QoS handling is required.
