Deploying the Dell Force10 MXL into a Cisco Nexus Network Environment
Split an MXL 40Gb Ethernet Interface into Four 10Gb Ethernet Links
The external QSFP+ 40Gb Ethernet ports can be configured as four separate 10Gb Ethernet links.
Physical connectivity is enabled by an optical split fiber cable or a split twinax cable. When a 40GbE
port is run in quad mode, it provides four 10Gb Ethernet interfaces that number sequentially starting
with the port number of the 40GbE interface. In the following example this makes four 10GbE links
numbered 33, 34, 35, and 36 from the single 40GbE port numbered 33.
MXL1#configure
MXL1(conf)#stack-unit 0 port 33 portmode quad
Please save and reload for the changes to take effect.

Note, as shown in the above example, splitting a 40GbE port into four 10GbE links requires saving the
configuration and reloading the MXL to take effect.
Save the Current MXL Configuration Settings
Always remember to save your settings so that they are not lost in case the switch is restarted.
