Chapter 5 Configuring the PA-8T-232 Interfaces
Checking the Configuration
Step 4 Complete the configuration by pressing Ctrl-Z—hold down the Control key while you press Z—or
entering end or exit to exit configuration mode and return to the EXEC command interpreter prompt.
Step 5
Write the new configuration to NVRAM as follows:
Router# copy running-config startup-config
[OK]
Router#
This completes the procedure for configuring controlled-carrier mode on an EIA/TIA-232 interface. For
additional information on configuring half-duplex operation on low-speed serial interfaces, refer to the
chapter “Configuring Interfaces” of the Configuration Fundamentals Configuration Guide publication.
For more information, see the
“Obtaining Documentation” section on page x and the “Obtaining
Technical Assistance” section on page xi .
Note
To configure EIA/TIA-232 interfaces for Binary Synchronous (Bisync) operation in Cisco 7200 series
routers, refer to the “Block Serial Tunneling (BSTUN)” section of the “Configuring Serial Tunnel
(STUN) and Block Serial Tunnel (BSTUN)” chapter of the Bridging and IBM Networking Configuration
Guide.
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 and loopback commands to check connectivity. This section includes
the following subsections:
• Using show Commands to Verify the New Interface Status, page 5-17
•
Using the ping Command to Verify Network Connectivity, page 5-32
• Using loopback Commands, page 5-32
Using show Commands to Verify the New Interface Status
Table 5-8 demonstrates how you can use the show commands to verify that new interfaces are
configured and operating correctly and that the PA-8T-232 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 .
