Usage Information Splitting a 40G port into 4x10G port is supported on standalone and stacked units.
• You cannot use split ports as stack-link to stack an MXL Switch.
• The split ports MXL switch unit cannot be a part of any stacked system.
• The unit number with the split ports must be the default (stack-unit 0).
• This set up can be veried using show system brief command. If the unit ID is dierent than 0, it must be
renumbered to 0 before ports are split by using the stackunit id renumber 0 command in EXEC mode.
The quad port must be in a default conguration before it can be split into 4x10G ports. The 40G port is lost in the
cong when the port is split, so be sure that the port is also removed from other L2/L3 feature congurations.
The system must be reloaded after issuing the CLI for the change to take eect.
