Testing connectivity
Test for connectivity by observing the LEDs related to network connection.

Pinging an IP address

To verify that a Brocade ICX 6650 device can reach another device through the network, enter a
command similar to the following at any level of the CLI.
Brocade# ping 192.168.0.0
Syntax: ping ip addr [source ip addr] [count num] [timeout msec] [ttl num] [verify] [no-fragment]
[quiet] [data 1-to-4 byte he x#, e.g. ab cdef00] [numeric] [size byte] [bri ef [max-print-per-sec
num 0-2047]]
NOTE
If you address the ping to the IP broadcast address, the device lists the first four responses.
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.
Brocade# traceroute 192.168.0.0
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.
Troubleshooting network connections
•For the indicated port, verify that both ends of the cabling (at the device and the connected
device) are snug.
•Verify that the 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.
•Use the CLI to verify that the port has not been disabled through a configuration change. If you
have configured an IP address on the device, you also can use the Web management interface
or IronView Network Manager.
•If the other procedures don’t resolve the problem, try using a different port or a different cable.
