Fabric OS 5.0.0 command reference guide 595
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 Core Switch 2/64 and SAN Director 2/128, 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 (refer to switchShow for an explanation of the two-letter codes) and, for serial ID SFP, 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 display: 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 Specify the slot number for a Core Switch 2/64 or SAN Director
2/128. For all other switches, this operand is not required. The slot
number must be followed by a slash ( / ) and the port number, so that
each port is represented by both slot number (1 through 4 or 7 through
10) and port number (0 through 15). The Core Switch 2/64 and SAN
Director 2/128 have a total of 10 slots. Slot numbers 5 and 6 are
control processor cards; slots 1 through 4 and 7 through 10 are port
cards. On each port card, there are 16 ports, counted from the bottom,
numbered 0 to 15.
portnumber Specify a port number. Valid values for port number vary, depending on
the switch type. This operand is optional.
-all Displays detailed data for all available SFPs on the switch. This operand
is not compatible with slotnumber/portnumber.
