McAfee® Network Security Platform 6.0 Troubleshooting Network Security Platform Sensor failover issues By having a check on the following connections and settings may resolve Sensor failover issues.  The Sensor model and Sensor image version on both the peer Sensors should be the same.  The Sensor License and IPv6 status should be identical on the peer Sensors.  Identify the interconnect port for the selected model because the interconnect ports vary for different models.  Check on the FO type setting on the Sensor. The failover creation would fail if the FO type is set on the primary Sensor.  The Sensor health status should be good and normal. External fail-open kit issues in connecting to the monitoring port External fail-open kit issues may occur due to disconnection of network device cables and improper cabling or port configuration. By having a check on the following connections may resolve the issue.  Ensure that the cables are properly connected to both the network devices and the Bypass Switch.  Ensure that the transmit and receive cables are properly connected to the Bypass Switch. XC cable connection issues for M8000 Sensors XC cable connection issues may occur in the M8000 Sensors due to improper cabling of XFP interconnect ports(XC2, XC3, XC5 and XC6). Check the following connections in the M8000 Sensors while facing such issues.  One end of an LC-LC fiber-optic cable should be plugged into the XC2 port of the primary Sensor and the other end of the cable to be plugged into the XC5 port of the secondary Sensor.  One end of an LC-LC fiber-optic cable should be plugged into the XC3 port of the primary Sensor and the other end of the cable to be plugged into the XC6 port of the secondary Sensor. 33

Sensor failover issues
By having a check on the following connections and settings may resolve Sensor failover
issues.
The Sensor model and Sensor image version on both the peer Sensors should be the
same.
The Sensor License and IPv6 status should be identical on the peer Sensors.
Identify the interconnect port for the selected model because the interconnect ports
vary for different models.
Check on the FO type setting on the Sensor. The failover creation would fail if the FO
type is set on the primary Sensor.
The Sensor health status should be good and normal.
External fail-open kit issues in connecting to the monitoring
port
External fail-open kit issues may occur due to disconnection of network device cables and
improper cabling or port configuration.
By having a check on the following connections may resolve the issue.
Ensure that the cables are properly connected to both the network devices and the
Bypass Switch.
Ensure that the transmit and receive cables are properly connected to the Bypass
Switch.
XC cable connection issues for M8000 Sensors
XC cable connection issues may occur in the M8000 Sensors due to improper cabling of
XFP interconnect ports(XC2, XC3, XC5 and XC6).
Check the following connections in the M8000 Sensors while facing such issues.
One end of an LC-LC fiber-optic cable should be plugged into the XC2 port of the
primary Sensor and the other end of the cable to be plugged into the XC5 port of the
secondary Sensor.
One end of an LC-LC fiber-optic cable should be plugged into the XC3 port of the
primary Sensor and the other end of the cable to be plugged into the XC6 port of the
secondary Sensor.
