Brocade SAN SFP Test

The SFP (Small Form-factor Pluggable) is a hot-pluggable transceiver module that plugs into the switch's ports to enable high-speed data transfer over fiber optic cables. SFP modules are crucial because they perform the conversion between the electrical signals used by the switch's internal circuitry and the optical (light) signals used for transmission over Fibre Channel cables. By tracking trends and deviations from normal operating ranges (e.g., rising temperature, dropping receiving/transmitting power), you can predict SFP failures before they cause an outage. The Brocade SAN SFP test helps the administrators in this regard!

This test monitors the ports in the target switch and reports the current temperature, voltage and tranmission/reception power. This helps the administrator in proactive maintenance, rapid troubleshooting, and failure prediction.

Target of the test : A Brocade 48000 switch

Agent deploying the test : An external agent

Outputs of the test : One set of results for each Slot:Port in the Brocade 48000 switch being monitored

Configurable parameters for the test

Parameter	Description
Test period	How often should the test be executed
Host	The IP address of the switch for which this test is to be configured.
SSH Port	The port at which the target switch exposes its SSH. The default port is 22.
Timeout	Specify the duration (in seconds) within which the SSH query executed by this test should time out in this text box. The default is 180 seconds.
SSH Username and SSH Password	Specify the credentials of a user who has the right to execute CLI (command-line interface) commands on the target switch and pull out metrics via SSH.
Confirm Password	Confirm the SSH Password by retyping it here.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Temperature	Indicates the current temperature of this port.	Celcius	A sudden increase in the value of this measure can point to poor airflow in the rack.
Current	Indicates the amount of electrical current that the SFP’s transmitter laser diode requires to produce the optical output in this port.	Amps
Voltage	Indicates the voltage received by this port.	Volts	A very high value of this measure can potentially damage the SFP's delicate CMOS circuitry.
Received power	Indicates the amount of power received by this port.	Micro Watts
Transmitted power	Indicates the amount of power transmitted by this port.	Micro Watts
