Troubleshooting Disabled or Down Interfaces
This topic provides troubleshooting information for specific problems related to interfaces.
Disabled port on EX 3200 switch with a 4-port Gigabit Ethernet uplink module (EX-UM-4SFP) installed
Problem
One of the last four base 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 EX 3200 switch is disabled.
The 4-port Gigabit Ethernet uplink module (EX-UM-4SFP) is installed.
When you check status with the show interfaces command or with the J-Web user interface, the disabled port is not listed.
Cause
The last four base ports use the same ASIC as the 4-port Gigabit Ethernet uplink module. Therefore, if you insert a transceiver in a 4-port Gigabit Ethernet uplink module installed in an EX 3200 switch, a corresponding base port from the last four base ports is disabled.
Solution
If you need to use the disabled base port, you should remove the transceiver from the 4–port Gigabit Ethernet uplink module. You can install the 2–port 10–Gigabit Ethernet uplink module (EX-UM-2XFP) instead. There is no ASIC conflict with the EX-UM-2XFP uplink module.
