SFP+ transceivers, you configure the 10-gigabit operating mode, and for SFP transceivers,
you configure the 1-gigabit operating mode. See “Setting the Mode on an SFP+ Uplink
Module (CLI Procedure)” on page 135.
By default, the SFP+ uplink module operates in the 10-gigabit mode and supports only
SFP+ transceivers. If you have not changed the module from the default setting and you
want to use SFP+ transceivers, you do not need to configure the operating mode.
If the operating mode and the configured mode for an SFP+ uplink module are different,
