Figure 37: Port Splitting Options
When using a port to split a data stream into 4-10 Gb/s data streams (four lanes) one of the other
ports on the gateway will be disabled (unmapped). See Table 19 to determine:
• which ports can be split into 4
• which ports can be split into 2
• which ports will be unmapped due to a 1X4 split
• When using this feature you MUST go into the MLNX-OS® chassis management sys-
tem and reconfigure the individual ports to split-2 or split -4. See the MLNX-OS® CLI
User Manual for instructions on port configuration.
When using this feature you MUST go into the MLNX-OS® chassis management system and
reconfigure the individual ports to split-4 or split-2. See the MLNX-OS® Software Command
Reference Guide for instructions on port configuration.
