LED Desired State Meaning
Abnormal
State
Meaning or 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:
v
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.
v Verify that the transmit port on the
device is connected to the receive port
on the other network device, and that the
receive port on the device is connected
to the transmit port on the other network
device. If you are uncertain, remove the
two cable connectors from the port
connector and reinsert them in the port
connector, reversing their order.
v Dust may have accumulated in the cable
connector or port connector. For
information about cleaning the
connectors, refer to “Cleaning the
fiber-optic connector” on page 24.
v If the other actions don’t 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:
v 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.
v 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.
If a problem persists after taking these actions, contact IBM technical support.
Tracing a route
To determine the path through which a device can reach another device, enter a
command such as the following at any level of the CLI on the 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 device displays up to
three responses by default.
