switchport
• When using the force option to add a PortChannel to a configuration that uses both Generation-1
and Generation-2 modules, follow these guidelines:
– Configure the PortChannel interface speed to auto max 2000, or add the Generation-1
interfaces followed by the Generation-2 interfaces.
– Generation-1 interfaces do not support the auto max 2000 speed.
– The force addition can fail for a Generation-2 interface if resources are unavailable.
Examples The following example configures switch port parameters for a Fibre Channel interface.
