(Yellow)
The port is
transmitting and
receiving user
packets. Off for an
extended
period. The port is not transmitting or receiving user packets. You
can do the following:
• Check the Link LED to make sure the link is still
established with the remote port. If not, take the
actions described in the Meaning or Action column for
the Link LED.
• Verify that the port has not been disabled through a
configuration change. You can use the CLI. If you
have configured an IP address on the device, you
also can use the Web Management Interface or
Brocade Network Advisor.
If a problem persists after taking these actions, contact Brocade technical support.
Troubleshooting network connections
To resolve problems that may arise with network connections:
• For the indicated port, verify that both ends of the cabling (at the Brocade device and the
connected device) are snug.
• Verify that the Brocade device and the connected device are both powered on and operating
correctly.
• Verify that the port has not been disabled by a configuration change. You can use the CLI. If you
have configured an IP address on the device, you also can use Brocade Network Advisor.
• Verify that you have used the correct cable type for the connection:
‐ For twisted-pair connections to an end node, use straight-through cabling.
‐ For fiber-optic connections, verify that the transmit port on the device is connected to the
receive port on the connected device, and that the receive port on device is connected to
the transmit port on the connected device.
• For copper ports, you can test the cable using Virtual Cable Testing. For more information, refer to
the chapter Hardware Component Monitoring in the FastIron Ethernet Switch Administration
Configuration Guide.
• If the other procedures do not resolve the problem, try using a different port or a different cable.
Support for digital optical monitoring
You can configure your Brocade device to monitor optical transceivers in the system, either globally or
by specified ports. When this feature is enabled, the system monitors the temperature and signal power
levels for the optical transceivers in the specified ports. Console messages and syslog messages are
sent when optical operating conditions fall below or rise above the XFP or SFP manufacturer’s
recommended thresholds. For details about this feature and how to configure it, refer to the FastIron
Ethernet Switch Administration Configuration Guide.
