Fabric OS 5.x command reference guide 625
Displays serial ID SFP information.
Synopsis
sfpshow [slotnumber/][portnumber] | [-all]
Availability
all users
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 SFPs capabilities,
interfaces, manufacturer, and other information.
NOTE: SFPs are polled by a background process. The sfpShow command retrieves the latest
information from cache. The cache values for each SFP are updated when the SFP is hot plugged, when
it is removed, or when the Fabric OS polls the SFPs. In the HP StorageWorks Core Switch 2/64, and the
SAN Director 2/128 and 4/256, if there is a lot of activity on the switch, poll updates might take several
minutes.
Use this command with no operand to display a summary of all SFPs in the switch. The summary displays
the SFP type (see switchShow for an explanation of the two-letter codes) and, for serial ID SFPs, the
vendor name and SFP serial number.
Use this command with the slotnumber and portnumber operands to display detailed information
about the serial ID SFP in that port. Use the -all operand to display detailed information for all
available SFPs.
For Finisar smart SFPs, five additional fields appear: module temperature, voltage, received optical
power, transmitted optical power (longwave only), and laser diode drive current.
Operands
This command has the following operands:
sfpShow
slotnumber For bladed systems only, specify the slot number of the port to display,
followed by a slash (/).
portnumber Specify the port number to display, relative to its slot for bladed
systems. Use switchShow to list valid ports. This operand is optional;
if omitted, this command displays a summary of all SFPs in the switch.
-all Displays detailed data for all available SFPs on the switch. This operand
is not compatible with slotnumber/portnumber.
