Version 8.3.16.1
This command is found on the 1000/10000 Base-T Ethernet interfaces.
When you enable auto , the system performs and automatic discovery to determine the optics installed
and configure the appropriate speed.
When you configure a speed for the 1000/10000 interface, you should confirm
command setting. Both sides of the link should have auto-negotiation either enabled or disabled. For
speed settings of 1000 or auto, the software sets the link to auto-negotiation and you cannot change that
setting.
In FTOS, the command speed 1000

CONFIGURATION
Version 8.3.16.1 Introduced on MXL 10/40GbE Switch IO Module
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
• 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 can be verified using CLI "show system brief". If the unit ID is different than 0, then it must
be renumbered to 0 before ports are split. By using the stack unit 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 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.
