Symptoms: 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.
A port on an SFP uplink module installed in an EX3200 switch is disabled
Problem Description: One of the ports (ge-0/1/0 through ge-0/1/3) of an SFP uplink module
installed in an EX3200 switch is disabled.
Symptoms: When you check the status with the show interface commands or with the
J-Web user interface, the disabled port is not listed.
Cause If you replace a transceiver multiple times in quick succession in a port in an SFP uplink
module installed in an EX3200 switch, it might cause an eeprom read problem. The
switch might not create an interface for that port and that port might be disabled.
Solution To enable the disabled uplink module port, remove the transceiver from that port and
install it after 10 seconds.
