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 New Interface Status, page 4-9
• Using the ping Command to Verify Network Connectivity, page 4-21
Using show Commands to Verify the New Interface Status
Table 4-4 demonstrates how you can use the show commands to verify that new interfaces are configured
and operating correctly and that the PA-2FE 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.
Note The outputs that appear in this document may not match the output you receive when running these
