If a problem persists after taking these actions, contact Brocade technical support.
Tracing a Route
To determine the path through which a Brocade FGS or FGS-STK device can reach another device,
enter a command such as the following at any level of the CLI on the Brocade device:
FGS 624> 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.
TABLE 10 Network Connection-Related LED States
LED Desired
State Meaning Abnormal State Meaning /Action
Link (Lnk) On (Green) A link is established with
the remote port. 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
“Cleaning the fiber-optic connectors”
on page 62.
•
If the other actions do not resolve the problem, try using a
different port or a different cable.
Active (Act) On or
blinking
(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 IronView Network
Manager.
