Testing Connectivity; Pinging An Ip Address; Observing Leds - Brocade Communications Systems ICX 6430 Hardware Installation Manual

You can configure your device to monitor optical transceivers in the system, either globally or by
specified port. When this feature is enabled, the system monitors the temperature and signal power
levels for the optical transceivers in the specified ports. Console messages and syslog messages are
sent when optical operating conditions fall below or rise above the SFP and SFP+ manufacturer's
recommended thresholds. For more information about digital optical monitoring, refer to the FastIron
Ethernet Switch Security Configuration Guide.

Testing connectivity

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

Pinging an IP address

To verify that a device can reach another device through the network, enter a command similar to the
following at any level of the CLI.
device> ping 10.33.4.7
Syntax: ping ip-addr [ source ip-addr ] [ count num ] [ timeout msec ] [ ttl num ] [ verify ] [ no-
fragment ] [ quiet ] [ data 1-to-4 byte hex#, e.g., abcdef00 ] [ numeric ] [ size byte ] [ brief [ 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.

Observing LEDs

After you install the network cables, you can observe certain LEDs to determine if the network
connections are functioning properly. The table below outlines the LEDs related to the network
connections, the desired state of each LED, possible abnormal states of each LED, and what to do if an
LED indicates an abnormal state.
