Tracing a route
To determine the path through which a
Brocade
device can reach another device, enter a
command such as the following at any level of the CLI on the
Brocade
device.
TurboIron> traceroute 192.33.4.7
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
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 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
IronView Network
Manager
.
•
For copper ports, you can test the cable using Virtual Cable Testing (VCT). Refer to "Monitoring
Hardware Components" in the
FastIron and TurboIron 24X 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
Brocade
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
FastIron and TurboIron 24X Configuration Guide
.
