Brocade ICX 6610 Stackable Switch Hardware Installation Guide - Manual (Page 76)

The CLI displays trace route information for each hop as soon as the information is received.
Traceroute requests display all responses to a given TTL. In addition, if there are multiple equal-cost
routes to the destination, the Brocade device displays up to two responses by default.
Troubleshooting network connections
• For the indicated port, verify that both ends of the cabling (at the device and the connected
device) are snug.
• Verify that the device and the connected device are both powered on and operating correctly.
• 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 the device is
connected to the transmit port on the connected device.
• Use the CLI to verify that the port has not been disabled through a configuration change. If you
have configured an IP address on the device, you also can use the Web management interface or
Brocade Network Advisor.
• If the other procedures don’t resolve the problem, try using a different port or a different cable.
Digital optical monitoring
You can configure your device to monitor optical transceivers in the system, either globally or by
specified port. 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 SFP and SFP+ manufacturer’s
recommended thresholds. For more information about digital optical monitoring, refer to FastIron
Configuration Guide.
