Testing network connectivity
After you install the network cables, you can test network connectivity to other
devices by pinging those devices. You also can observe the LEDs related to
network connection and perform trace routes.
Pinging an IP address
To verify that you can reach another device through the network, enter the ping
command at any level of the CLI on the device:
FastIron> ping 192.33.4.7
Syntax: ping
<ip addr> | <hostname> [source <ip addr>] [count <num>] [timeout <msec>] [ttl <num>]
[size <byte>] [quiet] [numeric] [no-fragment] [verify] [data <1-to-4 byte hex>] [brief]
See the Configuration Guide to read additional information about the parameters.
Note: If you address the ping to the IP broadcast address, the device lists the first
four responses to the ping.
Observing LEDs
After you install the network cables, you can observe certain LEDs to determine if
the network connections are functioning properly. Table 17 on page 55 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.
Note: Some modules use combined link and activity LEDs.
