You can display media information for all ports in an Brocade device by using the show media
command without options.
The ethernet slot-port parameter limits the display to a single port.
The to slot-port parameter displays information for a range of ports.
This results displayed from this command provide the Type, Vendor, Part number, Version and
Serial number of the SFP or XFP optical device installed in the port.
If no SFP or XFP device is installed in a port, the “Type” field will display “N/A”, the “Vendor” field
will be empty and the other fields will display “Unknown”.
Multi-rate optical transceivers are supported. In this case, if a multi-rate optical transceiver is
inserted in an Interface module, the “Type” parameter will display the transmission code for the
correct value for the port as determined by either the Interface module type or the configuration of
the port. There is one exception to this rule however. If a port is in the disabled state only one type
will be displayed. Once the port is enabled, the correct “Type” will be displayed in accordance with
the configuration.
Optics compatibility checking
This feature checks the installation of the following optical transceivers into Interface module ports
and shuts down the port if the transceiver is incompatible with the port:
• 10 GbE XFP – This interface is brought up if the XFP is compliant with Ethernet transmission
compliance.
• 1 Gb (100/1000) Ethernet interface will be enabled if the SFP is Ethernet capable
If the interface is incompatible with the optical transceiver installed, the port will not come up and
the syslog message “Incompatible optical trans-receiver detected on port n” is displayed. An SNMP
trap is also generated and the port is described as “down” because of “(incompatible transceiver)”
in the output from the show interface command.
Multi-rate optical transceivers (XFP and SFP) are supported as described in the following:
• In Multi-rate SFPs and XFPs, the EEPROM is programmed for multi-rate – for example both
Ethernet 1 Gb and SONET compliance codes can be programmed in the internal EEPROM of a
multi-rate optical transceiver.
• Multi-rate SFPs and XFPs are supported. The system software checks for transmission
compatibility against the interface configuration. Therefore an OC-12 interface will be brought
up if the SFP is compatible for both OC-12 SONET and 1 Gb Ethernet transmission. The same
SFP can also be used in a 1 Gb Ethernet interface.
• The show media command described in “Configuring optical monitoring” on page 29 continues
to show only one transmission rate even for multi-rate SFPs and XFPs. If the interface is
enabled and the SFP or XFP is compatible, the show media command only displays the
compatible transmission code in the “Type” field. If the interface is disabled, the show media
display depends on the module type. For Ethernet interface modules, the Ethernet compliance
code is shown. If the Ethernet compliance code is not set then the SONET compliance code is
displayed.
