sfpShow

sfpShow
Displays Small Form-factor Pluggable (SFP) transceiver information.
SYNOPSIS sfpshow
sfpshow [slot/]geport [ -f]
sfpshow -all
sfpshow -health
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 Fabric Watch state
transitions for each SFP and a time stamp of the last polling time. The power-on time is displayed for 16
Gbps SFPs and QSFPs only.
To configure the SFP state changes, use the fwFruCfg command. Use the -f option to refresh the SFP
information. This option is valid only when the spfShow command is issued for a specific port.
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 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
For bladed systems only, specifies the slot number of the port to display, followed
by a slash (/)
port
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.
