Solution Set a port in the uplink module as a VCP. See Setting an Uplink Module Port as a Virtual
Chassis Port (CLI Procedure).
One of the last four network ports on an EX3200 switch with an SFP or SFP+ uplink module
installed is disabled
Problem One of the last four built-in ports (ge-0/0/20 through ge-0/0/23 on 24-port models or
ge-0/0/44 through ge-0/0/47 on 48-port models) of an EX3200 switch with an SFP or
SFP+ uplink module installed in it is disabled.
When you check the status with the CLI command show interfaces ge- or with the J-Web
user interface, the disabled port is not listed.
Cause The last four built-in ports use the same ASIC as the SFP uplink module. Therefore, if
you install a transceiver in an SFP or SFP+ uplink module installed in an EX3200 switch,
a corresponding base port from the last four built-in ports is disabled.
Solution If you need to use the disabled built-in port, you must remove the transceiver from the
SFP or SFP+ uplink module. Alternatively, you can install an XFP uplink module instead
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.
