Usage Information
Splitting a 40G port into 4x10G port is supported only on a standalone unit.
— Split ports cannot be used as stack-link to stack an Z9000.
— Split ports Z9000 unit cannot be a part of any stacked system.
— The unit number with the split ports must be the default (stack-unit 0)
— This can be verified using show system brief command. If the unit ID is different than 0, then
it must be renumbered to 0 before ports are split by using the stackunit id renumber 0
command in EXEC mode.
— Stacking is not supported on FTOS Release 8.3.11.4.
The quad port must be in a default configuration before it can be split into 4x10G ports. The 40G port
is lost in the config when the port is split, so be sure the port is also removed from other L2/L3 feature
configurations.
The system must be reloaded after issuing the CLI for the change to take effect.
This command cannot be used if LR4 optics are inserted on the 40G interface.
