2.6.1 Supported Modules and Cables
2.6.2 Breakout Cables and Adapters
A 100GbE port can be split to two 50GbE ports, or to four (or less) 25GbE ports, using a break-
out cable.
Splitting a 100GbE QSFP28 port to 4 separate 25GbE ports (using a breakout cable) disables
(unmaps) the 100GbE port below it. See
Figure 45,“SN2700M Splitting Options”.
2.6.2.1 Using Breakout Cables with MLNX-OS
When using this feature, you should log into the MLNX-OS® CLI and configure the individual
ports to be ‘split-2’ or ‘split-4’.
