The interface on the port in which an SFP or SFP+ transceiver is installed in an SFP+
uplink module installed in an 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 1343.

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).
