PoE
(1-24/48)
On
(Green)
The port is
providing PoE
power to a
connected device.
Off
A link is not established with the PoE
device. You can do the following:
• Verify that the connection to the other
network device has been properly made.
• If the other actions do not resolve the
problem, try using a different port or a
different cable.
SFP (X1 - X4) for
ICX
7250-24Gdevices
SFP+ (X1 - X8) for
all other ICX 7250
devices
On or
flashing
(Green or
Yellow)
Flashing yellow
indicates the port is
transmitting and
receiving user
packets at 1 Gbps.
The SFP+ port is
operating at 10
Gbps. Flashing
green indicates the
port is transmitting
and receiving user
packets at 10
Gbps.
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 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 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
on page 72.
• Verify that the port has not been disabled
through a configuration change.
• Ensure that the SFP+ in both ends are of
the same optic type (for example. SR,
LR, LRM).
• If the other actions do not resolve the
problem, try using a different port or a
different cable.
If a problem persists after taking these actions, contact Brocade Technical Support.
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.
device> 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 two responses by default.
