Usage
Information
Splitting a 40G port into 4x10G port is supported on standalone and stacked units.
stack-unit stack-unit port number portmode quad dynamically fan-out
40G ports to 10G ports and vice-versa without reload in switch. Split ports cannot
be used as stack-link to stack an S4820T system.
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.
This command cannot be used if LR4 optics are inserted on the 40G interface.
