of an SFP or SFP+ uplink module. There is no conflict between the built-in network ports
and the ports on the XFP uplink modules.
The interface on the port in which an SFP or SFP+ transceiver is installed in an SFP+
uplink module installed in an EX3200 or EX4200 switch is down.
When you check the status with the CLI command
user interface, the disabled port is not listed.
By default, the SFP+ uplink module operates in the 10-gigabit mode and supports only
SFP+ transceivers. The operating mode for the module is incorrectly set.
Either SFP+ or SFP transceivers can be installed in SFP+ uplink modules. You must
configure the operating mode of the SFP+ uplink module to match the type of transceiver
you want to use. For SFP+ transceivers, configure the 10-gigabit operating mode and for
SFP transceivers, configure the 1-gigabit operating mode. See "Setting the Mode on an
SFP+ Uplink Module (CLI Procedure)" on page 1156.

Check the following:
Verify that there is no configuration mismatch.
Verify that all member ports are up.
Verify that a LAG is part of family ethernet—switching (Layer 2 LAG) or family inet
(Layer 3 LAG).
Verify that the LAG member is connected to the correct LAG at the other end.
Verify that the LAG members belong to the same switch (or the same Virtual Chassis).
