1.Verify the communication link.

2.Check the configuration settings.

3.Check the other elements of the ELAN.

4.Modify the load balancing setting, if desired.

5.Save the configuration in the /etc/rc and /etc/hosts files.

After you add an ELAN to an adapter and configure the interface, check to ensure that the filer can communicate with other clients through the ELAN. The easiest way to do this is to ping another LEC on the ELAN to ensure that information is traveling out through the ATM adapter and back again.

To ping an LEC, or any other client, use the ping command.

Command syntax: The ping command has the following syntax:

+￿￿,￿￿￿￿￿

host is the IP address of the computer to which you want to send an Internet control message protocol (ICMP) ECHO_REQUEST datagram.

Example: The following command sends the datagram to host 204.125.14.45, and waits for a response:

+￿￿,￿￿￿￿￿￿￿#￿￿￿￿￿#

If the host responds, ping prints “host is alive.” Otherwise, ping resends the ECHO_REQUEST once a second. If the host does not respond after 20 seconds, ping prints “no answer from host.”

From a diagnostics point of view, it is often useful to have an LEC configured on the switch.

Double-check the state of the adapters in the filer to ensure that the configuration is as you expect.

To check the configuration setting, use the elconfig show command.

Syntax: The elconfig show command has the following syntax:
