Tracing a route
To determine the path through which a TurboIron device can reach another device, enter a
command such as the following at any level of the CLI on the TurboIron device.
TurboIron> traceroute 10.33.4.7
Syntax: traceroute host-ip-addr [maxttl value] [minttl value] [numeric] [timeout value] [source-ip ip
addr]
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 three responses by default.
Troubleshooting network connections
• For the indicated port, verify that both ends of the cabling (at the TurboIron device and the
connected device) are snug.
• Verify that the TurboIron 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.
• 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 Brocade Network Advisor.
• For copper ports, you can test the cable using Virtual Cable Testing (VCT). Refer to "Monitoring
Hardware Components" in the TurboIron Configuration Guide.
• If the other procedures don't resolve the problem, try using a different port or a different cable.
Support for digital optical monitoring
You can configure your TurboIron 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+ or
SFP manufacturer recommended thresholds. For more information about digital optical monitoring,
refer to the TurboIron Configuration Guide.
