Defining the SFP/SFP+ Interface Options
The UFiber Multi-Mode fiber SFP module (UF-MM-1G) will be used to interconnect the EdgeSwitch and the EdgeRouter.
The UBNT branded SFP/SFP+ modules and DAC cables are officially supported and compatible with all EdgeSwitch and EdgeRouter models:
1Gbps SFP modules
UF-MM-1GMulti-Mode fiberUF-SM-1G-SSingle-Mode fiberUF-RJ-45-1GCopper RJ-45
10Gbps SFP+ modules
UF-MM-10GMulti-Mode fiberUF-SM-10GSingle-Mode fiberUF-SM-10G-SSingle-Mode fiberUF-RJ-45-10GCopper RJ-45
10Gbps DAC cables
UDC-1DAC cable (1m)UDC-2DAC cable (2m)UDC-3DAC cable (3m)
More information about these modules and DAC cables can be found on the store page here.
The SFP/SFP+ ports can be configured like any other interface on the EdgeSwitch. Some of the other options available to the SFP/SFP+ ports are:
Forced Duplex/SpeedThe interface duplex and speed can be set manually to 1Gb/full or 10Gb/full (depending on the module and switch).Auto-Negotiate Duplex/SpeedRely on hardware-based Auto-Negotiation to automatically set the duplex and speed.Auto-Detect Duplex/SpeedRely on software-based Auto-Detection to automatically set the duplex and speed (default).
If necessary in your setup, follow the steps below to force the duplex/speed on a SFP/SFP+ interface.
 |
GUI: Access the EdgeSwitch Web UI.
|
Navigate to the Dashboard 
to change the physical mode under the Mode column for interface 0/9.
Dashboard > Port Summary > Port 9 > Mode > 1Gbps FDX
 |
NOTE: EdgeSwitches that support 10Gbps interfaces such as the ES-16-XG will also display the 10Gbps FDX mode in this menu.
|
The above configuration can also be set using the CLI:
 |
CLI: Access the EdgeSwitch Command Line Interface.
|
Enter the following configuration to change the physical mode for interface 0/9:
enable
configure
interface 0/9
no auto-negotiate
speed 1000 full-duplex
exit
It is also possible to verify the physical mode and view the SFP/SFP+ statistics to troubleshoot any issues with the fiber cable or module. The available statistics and information is:
Module vendorModule serial numberModule part numberModule revisionLink length (50um)Link length (62.5um)ComplianceNominal bit rate (Mbps)Transceiver temperatureVoltage (V)Current (mA)Output Power (dBm)Input Power (dBm)Transmitter faultLoss of signal (LOS)
These values can be viewed by running the following commands from privileged mode:
