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 verified using show system brief command. If the unit ID is different 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 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 that 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.
