sfpShow

sfpShow
Displays Small Form-factor Pluggable SFP information.
Synopsis sfpshow
sfpshow [slot/]geport [ -f]
sfpshow -all
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's
capabilities, interfaces, manufacturer, and other information.
Use this command without operands to display a summary of all SFPs in the switch. The summary
displays the SFP type and, for serial ID SFP, the vendor name and SFP serial number. 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. Use the -f option to refresh the SFP information. This
option is valid only when a spfShow is issued for a specific port.
Use the -all operand to display detailed information for all available SFPs.
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 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 or Admin Domain restrictions that may
be in place. Refer to chapter 1, "Using Fabric OS commands" and Appendix A, "Command
Availability" for details.
Operands This command has the following operands:
slot
port
-all
868
For bladed systems only, specifies the slot number of the port to display,
followed by a slash (/)
Specifies the number of the port for which to display the SFP information,
relative to its slot for bladed systems. Use switchShow for a list of valid ports.
This operand is optional; if omitted, this command displays a summary of all
SFPs on the switch.
-f Refreshes the SFP information. This option is valid only when sfpShow is
issued for a specific port.
Displays detailed data for all available SFPs on the switch. This operand is
not compatible with slot/port operands.
