Checking the Configuration
After configuring the new interface, use the show commands to display the status of the new interface
or all interfaces, and use the ping command to check connectivity. This section includes the following
subsections:
• Using show Commands to Verify the Interface Status, page 4-5
• Using the ping Command to Verify Network Connectivity, page 4-22
Using show Commands to Verify the Interface Status
This section demonstrates how you can use the show commands to verify that interfaces are configured
and operating correctly and that the port adapter appears in them correctly. Sample displays of the output
of selected show commands appear in the sections that follow. For complete command descriptions and
examples, refer to the publications listed in the “Related Documentation” section on page viii.
If an interface is shut down and you configured it as up, or if the displays indicate that the hardware is
not functioning properly, ensure that the interface is properly connected and terminated. If you still have
problems bringing up the interface, contact a service representative for assistance. This section includes
the following subsections:
• Using the show controllers Commands, page 4-6
• Using the show protocols Command, page 4-6
• Using the show running-config Command, page 4-6
• Using the show startup-config Command, page 4-7
• Using the show version or show hardware Commands, page 4-8
• Using the show diag Command, page 4-13
• Using the show interfaces Command, page 4-17
Choose the subsection appropriate for your system. Proceed to the “Using the ping Command to Verify
Network Connectivity” section on page 4-22 when you have finished using the show commands.
