110 BigIron RX Installation Guide53-1001811-01Testing network connectivity4Testing network connectivityAfter you cable the fiber optic modules, you can test connectivity to other network devices bypinging those devices. You also can perform trace routes.To resolve problems that may arise with network connections:• For the indicated port, verify that both ends of the cabling (at the Brocade device and theconnected device) are snug.• Verify that the Brocade device and the connected device are both powered on and operatingcorrectly.• 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 thereceive port on the connected device, and that the receive port on device is connected tothe transmit port on the connected device.• 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 the Web managementinterface or IronView Network Manager.• For copper ports, you can test the cable using Virtual Cable Testing. Refer to “Using virtualcable testing to diagnose a cable” on page 111.• If the other procedures do not resolve the problem, try using a different port or a differentcable.Pinging an IP addressTo verify that a BigIron RX Series switch can reach another device through the network, enter acommand such as the following at any level of the CLI on the BigIron RX Series switch:BigIron RX> ping 192.33.4.7Syntax: ping | [source ] [count ] [timeout ] [ttl] [size ] [quiet] [numeric] [no-fragment] [verify] [data <1-to-4 byte hex>][brief]NOTEIf you address the ping to the IP broadcast address, the device lists the first four responses to theping.Tracing a routeTo determine the path through which a BigIron RX Series switch can reach another network device,enter a command such as the following at any level of the CLI on the BigIron RX Series switch:BigIron RX> traceroute 192.33.4.7Syntax: traceroute [maxttl ] [minttl ] [numeric] [timeout ][source-ip ]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-costroutes to the destination, the Brocade device displays up to three responses by default.
