sfpShow sfpShow Displays Small Form-factor Pluggable (SFP) transceiver information. Synopsis sfpshow sfpshow [slot/]port -link [-force] sfpshow [slot/]geport [ -f] sfpshow -pid pid sfpshow -all sfpshow -health sfpshow --help Description Use this command to display information about Serial Identification SFPs, also known as module definition "4" SFPs. These SFPs provide extended information that describes the SFP capabilities, interfaces, manufacturer, and other information. Use this command without operands to display a summary of all SFPs in the switch. For each port, the summary displays the SFP type and, for serial ID SFP, the vendor name and SFP, serial number, and speed capability (in Gbps). Refer to switchShow for an explanation of the two-letter codes. Use this command with a port number to display detailed information about the serial ID SFP in the specified port. In this mode, this command displays values described in the "Gigabit Interface Converter" spec by Sun Microsystems, et al. The detailed view also displays the total number of Monitoring and Alerting Policy Suite (MAPS) state transitions for each SFP and a time stamp of the last polling time. The power-on time is displayed for 16 Gbps/32 Gbps SFPs and QSFPs only. Use the -all operand to display detailed information for all available SFPs. On switches running Fabric OS v7.0.0 or later, this view includes the power on time for the switch in years and hours. For "smart" SFPs including mini-SFPs, this command displays additional fields, including module temperature, voltage, received optical power, transmitted optical power (long wave only), laser diode drive current, optional status/control register, alarm and warning flags, as well as high and low thresholds programmed on the SFPs. A "Can not read Serial Data!" message indicates that an SFP ID could not be detected on that location (it could be a fixed port type, or an unsupported SFP type, or an interchassis link without a cable). Notes The identifier field has the value 3 for SFPs and mSFPs. mSFPs are supported only on FC8-64 blades and can be identified with OUI 00:05:33. The sfpShow command does not reflect changes in the sfpShow output if any SFPs are replaced or removed while a port or a switch is disabled. The execution of this command is subject to Virtual Fabric restrictions that may be in place. Refer to "Using Fabric OS Commands" and "Command Availability" for details. 1002 Brocade Fabric OS Command Reference 53-1004112-02
