Tracing a route

To determine the path through which a Brocade device can reach another device, enter a
command similar to the following at any level of the CLI on the device.
FCX648SHPOE Switch> traceroute 192.33.4.7
Syntax: traceroute <host-ip-addr> [maxttl <value>] [minttl <value>] [numeric] [timeout <value>]
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
Abnormal State Meaning or Action
Off A link is not established with the remote port. You can do the
following:
•
Verify that the connection to the other network device has
been properly made. Also, make certain that the other
network device is powered on and operating correctly.
•
Verify that the transmit port on the Brocade device is
connected to the receive port on the other network device,
and that the receive port on the Brocade device is
connected to the transmit port on the other network
device. If you are not certain, remove the two cable
connectors from the port connector and reinsert them in
the port connector, reversing their order.
•
Dust may have accumulated in the cable connector or port
connector. For information about cleaning the connectors,
refer to
•
Verify that the port has not been disabled through a
configuration change.
•
Check that the configuration has not forced the use of the
RJ45 port shared with the SFP port.
•
If the other actions don't resolve the problem, try using a
different port or a different cable.
Off A link is not established with the remote port. 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.
