Chapter 4 Configuring the PA-E3
Checking the Configuration
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 version or show hardware Commands, page 4-15
•
Using the show diag Command, page 4-20
•
Using the show interfaces Command, page 4-23
These subsections offer some platform-specific output examples using the show commands. Choose the
subsection appropriate for your system. Proceed to the
“Using the ping Command to Verify Network
Connectivity” section on page 4-29
when you have finished using the show commands.
