By default, interface process operations are placed in the file named dcd and three 1-MB
files of tracing information are maintained.

SFP+ uplink modules are supported on EX3200 and EX4200 switches. You can use these
uplink modules either for two SFP+ transceivers or four SFP transceivers. You configure
the operating mode on the module to match the type of transceiver you want to use—that
is, for SFP+ transceivers, you configure the 10-gigabit operating mode, and for SFP
transceivers, you configure the 1-gigabit operating mode.
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.
To set the operating mode of an SFP+ uplink module:
Change the operating mode to the appropriate mode for the transceiver type you
