Brocade Fabric Watch Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 59)

Fabric Watch also monitors the Brocade Quad SFP (QSFP) and, as for 16 Gbps SFPs, if configured
thresholds are crossed, Fabric Watch generates an SNMP alarm, a RASLog message, and an e-mail
alert for the following SFP areas:
• Current
• Voltage
• Temperature
• RXP
NOTE
On core blades, only 16 Gbps QSFPs can be installed.
Voltage and temperature monitoring using the QSFP
A QSFP connects four ports of one core blade of a chassis to another core blade of a different chassis.
Typically, voltage and temperature values for all ports, on a single chassis, that are connected using
one QSFP unit will have the same values, resulting in redundant information. To avoid this, Fabric
Watch monitors the voltage and temperature areas on the first available port of the QSFP unit only,
which reduces the display of redundant information. If the port crosses the voltage or temperature
thresholds, Fabric Watch takes the SNMP, RASlog, or e-mail action on the first port and sends a
warning to the user that the other ports are affected.
Logical switch considerations with QSFP
Fabric Watch monitors QSFPs in each logical switch. Temperature and voltage are monitored on the
first available port of the QSFP unit to minimize the display of redundant information. However, if
individual ports of a QSFP belong to different logical switches, then there will be separate action
notifications for each logical switch.
NOTE
This applies only to QSFP voltage and temperature monitoring.
Monitoring the SFP and QSFP
You can use the thMonitor command to enable the Brocade 10 Gbps and 16 Gbps SFPs and 16 Gbps
QSFPs. By default, the 16 Gbps SFP and QSFP are disabled.
To enable or start the monitoring of the SFP and QSFP, enter the thMonitor command using the
following parameter:
switch:admin> thmonitor --enable brcdSfp
To disable or stop the monitoring of the SFP and QSFP, enter the thMonitor command using the
following parameter:
switch:admin> thmonitor --disable brcdSfp
To show the monitoring status of the SFP and QSFP, enter the thMonitor command using the following
parameter:
switch:admin> thmonitor --show brcdSfp
